Types of roll insulation. Roll insulation for walls: choosing the best thermal insulation. Review of manufacturers Izover, Knauf, Ursa

How do you look at the prospect of reducing home heating costs by almost a third? We think this is a case where comments are unnecessary. It is possible to achieve such a result; you just need to choose the right thermal insulation for the roof.

One of the most common thermal insulation materials is mineral wool, in particular in the form of mats. However, when it is necessary to insulate, for example, large areas, such a solution is ineffective. For such cases, roll insulation is more suitable.

All materials of this type have approximately the same advantages, which explains their high demand. We are talking about their qualities such as

• low thermal conductivity,
• good sound insulation,
• optimal hygroscopicity,
• high hydro-repellent properties,
• chemical resistance,
• fire safety.

And this is not the whole list.

Rolled insulation, due to its elasticity and flexibility, easily restores its shape and is suitable for working on uneven surfaces. It has no temperature restrictions, as it retains its performance characteristics at extreme temperatures.

Scope of application of insulation in rolls

It is successfully used for roofs and basements, floors and ceilings, pipes and more. Installing thermal insulation from this material is a fairly simple process. Moreover, the work can be done independently, without the involvement of additional labor. Therefore, this type of thermal insulation has gained great popularity in private construction, in particular, bathhouses, outbuildings, etc.

Types of insulation

A separate group includes materials that have a protective layer of foil. They are somewhat more expensive than others, but they have many additional valuable properties.

Foil itself does not have the thermal conductivity necessary for insulation, however, it effectively retains heat due to the ability of the reflective surface to block infrared rays from the room. It is worth noting that at the same time it does not allow their penetration from the outside. The last one is quite useful quality for roof insulation, especially in hot summers, when the roof gets very hot under the influence of sunlight.

Roll foil insulation allows you to ensure the maximum length of the material, that is, it is laid from one whole strip, which is extremely important for its efficiency. . These include foam rubber, polyethylene and other materials in roll form

These materials do not hold their shape and are easily rolled up. They are quite effective and easy to work with. Unlike foil thermal insulation, they are used in combination with a vapor barrier, which creates an ideal tandem against the cold.

This is the most common type of insulation. This form of packaging is considered by many to be optimal, since with this approach long strips of insulator occupy a small volume. Most often, floor beams or mounting profiles are installed in increments equal to the width of the roll. This greatly simplifies installation: firstly, the material is simply spread over the surface and secured, and secondly, no unnecessary seams are formed.

How to choose the right roll insulation for your roof How to choose roll insulation. Types of roll insulation. What are the advantages of rolled foil insulation. Characteristics of roll

Popular manufacturers

Products on the market various manufacturers. Each brand has its own characteristics and advantages.

Knauf

The German manufacturer offers a material that does not contain formaldehyde. Knauf products are safe for people. Mineral wool does not cause allergies, but it should be installed with gloves. Microscopic fragments included in the insulation can cause skin irritation.

Knauf roll materials are not of interest to insects and rodents. In addition, they are able to protect against external noise due to good soundproofing characteristics. They are characterized by low thermal conductivity and good air permeability. The company offers materials for protecting walls, slabs, pipes and other surfaces in dachas and country houses.

Izover

High density insulation. The French manufacturer offers products of various thicknesses: from 20 to 150 mm, which significantly expands the possible area of ​​use of Isover insulation.

The company catalog presents thermal insulation material with foil, which is often used for insulating pitched roofs, walls, ceilings, and installing heated floors not only in houses, but also in baths and saunas. In terms of flammability it corresponds to the first class.

Ursa

High-quality professional insulation with a long service life. Has excellent soundproofing characteristics. Does not burn. When exposed to flame, it does not emit toxic substances. It does not break or crumble during installation. Pleasant to the touch.

When insulating the walls of private houses, M-11 is most often used. When performing thermal insulation work in an industrial complex, preference is given to P-30.

Topizol

The insulation can have a thickness of 3 – 20 mm. Suitable for various climatic zones, including for regions with high humidity. Doesn't rot. It has good vapor permeability. When ensuring sufficient tightness of the seams, it can withstand gusts of wind.

Used to protect walls, roofs, including attics, and floors. It is lightweight, which facilitates transportation and reduces the requirements for the strength characteristics of the insulated surface. Able to maintain its performance characteristics for at least 30 years.

Installation can be done independently without special equipment.

Penofol

Multilayer foil material comes in several types. Type A provides for the presence of one foil layer. Type B has self-extinguishing polyethylene between layers of high-quality aluminum foil. Type C comes with a special adhesive base, which greatly simplifies its installation. Type A has the lowest cost and the least rigidity.

Penofol's foil thickness is 12 - 30 microns with a base thickness of 2 - 10 mm. To insulate surfaces operating in fairly harsh conditions, material up to 40 mm thick can be used.

Eco-friendly, safe, suitable for insulating children's rooms.

Scope of application of roll insulation

Roll insulation materials are used for thermal insulation of vertical and horizontal surfaces. Foil material is indispensable for creating thermal insulation in bath rooms, as it retains heat well and has heat-reflecting properties. And this material has found wide application for thermal insulation of individual structures, joints, and in hard-to-reach places.

Let's look at the main ways to use rolled heat insulators.

Rolled thermal insulation for walls

Rolled wall insulation can be used as a heat-insulating material applied under decorative finishing, including under wallpaper.

The application technology is very simple:

• self-adhesive material is glued to a wall that has been prepared in advance, leveled and cleared of debris and old finishes;
• A cement-based adhesive is applied to the heat insulator layer, its properties reminiscent of liquid plaster;
• After the adhesive has hardened, you can begin gluing the wallpaper.

The use of such material for wallpaper will significantly increase the heat-retaining properties of the walls, as well as their sound insulation.

Rolled floor insulation

It is used as a substrate for various types of decorative floor coverings. It not only has heat-insulating properties, but also gives the floor “softness”, eliminates squeaks and sounds when the floor covering shrinks and moves.

In some cases, a foil thermal insulator can be used to insulate the floor; this will increase heat retention; however, the cost of materials reinforced with foil is 30–60% more expensive.

The technology for performing floor insulation work using foamed polymer in rolls is very simple:

• the material is glued to a wooden floor or concrete screed using an adhesive composition or self-adhesive properties;
• leveled so that there are no “bubbles”;
• The floor covering is laid on top.

The advantages of such a heat insulator include ease of installation, lack of debris, durability and environmental Safety. When choosing a roll insulation for the floor, it is worth remembering that the “softer” the floor covering, the denser the insulation should be.

In other words, it is better to use a polymer with maximum density under linoleum, otherwise when walking you will “drown” in floor covering, but under laminate or parquet you can lay polymer with any density.

Rolled roof insulation

Suitable for thermal insulation of pitched and flat roofs. A roof insulated with such material will remain warm for several decades. You can install thermal insulation on your own, without involving highly paid specialists. The heat insulator is located between the elements of the roof rafter system, and distortions, the formation of waves and other defects are not allowed.

In some cases, for example, when insulating residential attic room or in regions with cold climates, it is recommended to lay insulating polymer in two layers.

The technology for installing roof thermal insulation depends on the design features. Best option when thermal insulation is calculated at the design stage. In this case, the work boils down to: roll material rolled out and glued to the inner surface of the roof, a layer of vapor barrier material and the final finishing is installed, for example, siding, lining, etc.

Application of roll insulation

This technology is far from perfect and creates only the illusion of real savings in material resources, since in fact this type of insulation is inferior in all respects to such sprayed analogues as polyurea

Another difficulty is the application technology. It should be mentioned right away that all surfaces must be prepared: thoroughly cleaned or even washed. Even minor contamination can lead to negative consequences. Self-adhesive insulation is applied similar to adhesive tape, but this method is less effective. Over time, the glue loses its properties, especially under the influence of temperature changes, and the material peels off. Fused insulation is applied using a gas torch. This is a slow and painstaking process, but the grip is somewhat better, although there is no guarantee that it will not give way in some places.

Regardless of whether roll waterproofing of the floor or any other surfaces will be carried out, this process takes a lot of time and effort. Accordingly, the deadline for putting the facility into operation is being delayed. And this work is not cheap. Therefore, this technology is far from perfect and creates only the illusion of real savings in material resources, since in fact this type of insulation is inferior in all respects to such sprayed analogues as polyurea.

Advantages and disadvantages

The main advantages of rolled material are:

• Versatility. Suitable for thermal insulation of any surfaces. For complex spatial shapes, including curved ones, you can cut out a suitable piece.
• Minimum requirements for surface preparation before installation.
• Gain in terms of material price and work productivity during insulation large areas walls, especially straight sections.

Roll materials have disadvantages.

• High labor intensity when laying in frequent lathing; additional time is required for cutting.
• Low rigidity does not allow them to be used where it is necessary to withstand significant loads.

In general, the advantages compensate for the disadvantages, which explains the high popularity of roll materials among consumers.

The materials are harmless to health provided they are correct operation and compliance with fire safety regulations.

Types of roll insulation

Mineral wool

Available in several modifications. A common disadvantage is hygroscopicity. All insulation materials must be protected from direct contact with liquids; the difference between them is only in the intensity of its absorption.

• Glass wool. Pros: one of the cheapest (made from broken glass that has been melted down), unattractive to rodents and insects (often used when installing heated floors). Increased density, the ability to dampen sounds, and resistance to combustion add advantages to glass wool in use. The downside is the complexity of working with the material. When installing glass wool-based roll insulation, you cannot do without protective equipment. And not only the respiratory and visual organs; you need thick, closed clothing - microscopic fractions of glass penetrate literally everywhere.
• Slag-like. It is also based on waste, but from the metallurgical industry. In terms of cost, this insulation is comparable to glass wool (even somewhat cheaper), but in terms of resistance to high temperatures it is inferior. But in terms of thermal conductivity it is the leader among mineral wools. In all other characteristics, it is approximately on the same level as other insulation materials of this group. Cons: absorbs moisture (increased hygroscopicity), does not dampen noise well.

There is also a drawback that makes the use of slag wool for insulation of metal pipes impractical. It is not recommended to be used for thermal insulation due to residual acidity - it has a destructive effect on steel.

Basalt wool. The raw materials are processed rocks. Pros: ability to withstand high temperatures (up to +700), optimal combination thermal conductivity/density characteristics. The peculiarity of the material is that after getting wet it does not lose its thermal insulation properties (although there is a limit on the percentage of humidity), it is characterized by high sound absorption, fire-resistant, and “eco-friendly” (safe for allergy sufferers).

There are few downsides: this insulation requires high-quality vapor barrier, which cakes over time.

Any of the listed thermal insulation materials is also sold in a “foil” modification. The thinnest layer of aluminum increases the heat-reflecting properties of the product and protects it from contact with moisture.

Polymers

All roll insulators are made on the basis of foamed polyethylene or polypropylene. They differ in characteristics, but given the small thickness of the canvases, the difference in thermal conductivity between them is not particularly significant, so they can be considered identical. The most advertised, although not the only representatives of this group of elastic insulation materials on the market: Penofol (PE) and Penotherm (PP).

Russian products under the brands Energoflex, Energofloor, Jermaflex (combined material) from ROLS ISOMARKET have good reviews. It is relatively new on the market, but judging by the exchange of opinions on the Internet, it has proven itself to be an effective and versatile insulation material. Its quality was also appreciated by specialists.

The main role is given to the metallized layer. It is the foil that prevents heat rays from passing through the material. The heat insulator is covered with it on one or both sides; The choice of option is determined by the application conditions.

When choosing insulation from an unknown brand, you may encounter a substitution of concepts. To reduce costs, some manufacturers apply metallized spraying to the thermal insulation instead of a layer of foil. Such a screen is not durable, and is significantly inferior in efficiency to an aluminum coating.

So which option is better to choose cotton wool or polyethylene foam?

The main point that is important to understand is that foamed polyethylene or polypropylene in the form of rolls is precisely thermal insulation, that is, a material whose purpose is to slightly improve the characteristics of walls, and not to fully insulate them. Regardless of where it will be fixed - from the inside or from the front part

But basalt wool is already a real insulating layer. True, if used indoors, the wall will still freeze, but noticeably less heat will escape from the room.

It turns out that foam propylene from the inside will give less effect than cotton wool, since the temperature will only rise by a degree and a half. And even if you perform external installation, the “picture” will be the same, but with only one positive thing- the wall will freeze a little less and condensation from the room will disappear.

At the same time, the material has an undeniable advantage - it is cheap and very easy to install. It is more difficult and expensive to work with cotton wool because you will need to make a false wall (usually drywall) to protect the basalt fibers, and in addition, it is important to take care that moisture does not get into the structure of the material. If this happens, then the effect of all the work done will be zero, since all the thermal insulation qualities will very quickly disappear.

Here it seems that cotton wool is better anyway (because it’s “warmer”), but everything is decided by the nuances of the situation. Yes, cotton wool seems to be good, but what is the point in it if, for example, you need to insulate a shower room not in the house, but, for example, in the country and you don’t want to invest? The obvious budget solution in this case is a metallized insulator - stick it on the wall and forget it.

But in the case of a more or less capital approach, but again in the absence of noticeable financial resources- it is better to opt for mineral wool and insulation from the inside. It turns out that there is no ideal option and you need to make a decision only based on the characteristics of the project.

Characteristics

Thermal insulation material in rolls, produced under various brands, is characterized by general characteristics.

Environmental friendliness

The insulation responds regulatory requirements environmental safety.

As a rule, it contains salts of heavy metals, alkalis, acids, oxides, phenols or toxic organic compounds, which are inactive at room temperature, are present in minimal quantities.

Due to its low chemical activity, thermal insulation practically does not interact with aggressive environments, and therefore, for example, is not afraid of exposure to solvents.

Biological resistance and fire safety

The material has a high level of biological resistance. As a result, there are no rodents, fungus, or mold in it. It is of no interest to insects and animals as food. Depending on the composition and other characteristics, the insulation can withstand high temperatures.

Air and vapor permeability

If insulation is used to insulate floors or walls, air permeability is an important indicator.

When using rolled materials, you do not have to worry about excessive dampness in the room, condensation and other negative phenomena, provided that the installation is done correctly.

When going shopping, it is worth remembering the following aspects of your choice:

1. Various variations of insulation are suitable for indoor and outdoor use.
2. The surface that will be covered with roll insulation also matters. There is a fundamental difference between the materials used to insulate the ceiling and walls. Each of these bases has its own insulation.
3. It is also important to remember what material the walls are made of. A thermal insulator for a wooden base may not be suitable for a concrete base and vice versa.
4. When choosing the thickness of the material, it is worth taking into account the temperature conditions in winter and the climate characteristics for a particular region.
5. Before purchasing, you should definitely familiarize yourself with quality certificates and other permitting documentation on the selected roll insulation, and in addition, make sure the integrity of the packaging. Moisture, even in small quantities, can negatively affect the calculated parameters of the material and its properties.

Choose high-quality material from trusted manufacturers

Insulation in rolls is available on the market in a wide range. Each of them has its own characteristics, positive and negative characteristics. The choice of a specific option is up to the user, but if there are difficulties, you should not rely on chance. It is better to seek help from professionals and save your nerves and money.

3 Rolled foil thermal insulation

Rolled foil insulation on the market is usually made either from polyethylene foam (the fairly popular brand Penofol) or from polypropylene (Penotherm).

These are two almost identical materials, the difference between which is only physical and mechanical characteristics. If we consider only those that affect the direct effectiveness of use as a thermal insulation material, then foil roll insulation for walls based on polypropylene appears more preferable.

Thus, the polypropylene base has an order of magnitude lower thermal conductivity (a difference of about 30%), less moisture absorption and better resistance to external mechanical influences.

In fact, the last factor can be neglected, since foil insulation materials themselves, due to their minimum thickness, do not perform effective insulation if the foil is damaged, so it is important to look at the quality of the foil coating. .

Rolled penofol with one-sided foil

Unscrupulous manufacturers, in order to reduce the cost of products, may not use aluminum foil as a shielding layer, as required by technology, but ordinary metal spraying.

The efficiency of such spraying is much lower than that of foil, but the cost of such products, sold under the guise of high-quality insulation, is comparable to high-quality products from trusted manufacturers. When choosing foil-covered insulation for walls, floors, or pipes, carefully check the quality of the shielding layer.

High-quality foil thermal insulation has the following advantages:

• High heat shielding coefficient, about 97%;
• Wide functionality - foil materials are used not only for household insulation of walls, floors and ceilings, they are also widely in demand for thermal insulation of all kinds of industrial equipment;
• Minimum roll weight;
• Easy to install - foil thermal insulation does not require frames, anchoring and similar frills; it sits on the wall on polyurethane foam, or regular construction adhesive;
• Minimum cost - the price of foil materials is significantly lower than that of mineral wool;
• Complete vapor barrier;
• Safety for the human body.

Foil thermal insulation has only one significant drawback - it is susceptible to burning. The operating temperature of polypropylene is 150 degrees, polyethylene foam is 80 degrees.

Characteristics

Rolled insulation materials are characterized by the following main parameters:

• Environmentally friendly. All models on the market must comply with safety requirements for installation, operation and disposal. They must contain small amounts of harmful substances; these substances must not be released from the insulation during its storage, installation and during use. The packaging indicates the disposal method. The materials are resistant to organic solvents and other active substances.
• Fire and bioprotection. Mineral insulation does not burn on its own and prevents the spread of flame. Foam materials can withstand fire for a certain time. The materials prevent the formation of mold and repel rodents.

• Air and vapor permeability. Key characteristics. They show how much air or water vapor at a certain temperature can leak through a unit area of ​​material. Vapor permeability is necessary in order to remove excess moisture from the room to the outside through the walls and their ventilation systems.
• Strength. Important characteristic insulation under wallpaper. Touching, including with hard objects, should not damage the wallpaper.

Which roll insulation to buy

Roll insulationis the name of a whole class of lightweight thermal insulation, widely used in civil and industrial construction. They are made from staple fiberglass with the addition of various binding materials, fillers, water repellents (substances that repel water), which give them softness, elasticity and resilience. Rolled thermal insulation is the most inexpensive of all types of insulation, and therefore is in consistently high demand among builders.

This section of the site presents roll insulation, their price and parameters of the rolls. All information about products from different manufacturers is given on one page. Here you will find a brief description of each of them.

• ROLL INSULATIONS URSA

This is a very well-known line of insulation materials from the European manufacturer - the URALITA concern. URSA brand roll insulation materials are soft elastic mats made of staple fiberglass. Each brand has its own marking, which allows customers to easily navigate the characteristics of the material and, accordingly, its purpose. URSA insulation products are high quality lightweight insulation materials recommended for use in horizontal unloaded building structures. Good thermal characteristics, ease of transportation and installation make them in great demand for many years.

A special place in the line of roll insulation products of the URSA Concern is occupied by new generation insulation materials under the URSA PUREONE trademark (in rolls and slabs). Acrylic, a neutral and safe polymer, is used as a binding component. The production technology of these insulation materials excludes the use of phenols and formaldehydes, which makes them particularly environmentally friendly. They are widely used in Europe, America, Japan for heat and sound insulation indoors. In Russia they also gained well-deserved popularity.

• KNAUF ROLL INSULATIONS

These are natural mineral wool insulation materials made on the basis innovative technology ECOSE. During the manufacturing process, binders based on natural components are used, so it has a pleasant color of natural flax and a structure that is pleasant to the touch. Due to environmental friendliness, such insulation can be used indoors.

You can always contact our specialists, who will tell you where you can find additional information about the insulation you are interested in or give advice on installing the material.

Installation technology

The technology for installing roll insulation is slightly different from slabs. They begin to insulate the walls or floor initially. The walls are mainly made of slabs, as is the straight ceiling. Therefore, often, floors and pitched ceilings-walls are suitable for insulation and installation. When insulating the floor, it is worth looking at what type of insulation is available.

Insulation in foil is mainly used, but sometimes rolls of insulation are covered with ordinary heat-insulating foil or metal film. The insulation should extend 1 cm away from the walls. This is due to the fact that when temperature changes, the material contracts and expands. Absence free space in metallized or foil insulation leads to its deformation and damage over time.

Ceiling (pitched) insulation is attached between the rafters, cutting out a little more in order to insert it better between the boards. They are inserted strictly from bottom to top to avoid voids. After installation, the surfaces are clamped with main profiles or boards for application of additional (for example, vapor barrier) materials on top. The work is carried out especially carefully.

Let's move on to installing walls with roll-type insulation from the inside. It is produced by preparing walls for pasting. A special glue for cotton wool is diluted; the wall should not be covered with putty or plaster; only bare concrete or brick is allowed. The composition is applied to the wall evenly using a special comb, after which they begin gluing the rolls, which can be cut for convenience.

In this case, it is advisable to make the wall itself level, flat, if there are no further plans for sewing it into a box or gluing glass wallpaper. After the material is mounted on the wall, you need to screw it on. Each petal should be slightly recessed in the cotton wool. At least 5 fixing holes are required per 1 m2. It is better to fasten the sheets themselves and the space between them (in this case, both sheets will adhere, which will avoid warping and ensure level and plane).

After the sheets have set, a layer of glue should be applied. The technology is similar to puttying, only with a different solution

It is important to monitor the level and plane. It is necessary to make at least two passes, since it will be problematic to lay a good layer the first time

After leveling, regardless of the type of room, you can proceed to the next work. When installing sheets of drywall inside the house, they are attached using dowels to a layer of thermal insulation, which should preferably be treated with glue, as in the previous paragraph.

About the advantages of URSA roll insulation, see the video below.

Operational imperfections and maintenance difficulties

Each type of waterproofing material has its own characteristics unique features. Thus, TechnoNIKOL, which, according to the manufacturer, can withstand heavy mechanical loads, may not withstand increased soil mobility. Therefore, many people use a modification for waterproofing road substrates from the same manufacturer. But these are unjustified costs.

As for maintenance, for example, if the polyurea coating is damaged, it is enough to simply spray a small layer locally on the area. But roll waterproofing that has peeled off in any place requires serious repairs. It is necessary to remove it, at least in this place, prepare the base, reapply insulation, covering the resulting seams. Of course, we are not talking about any aesthetics, and the quality of such a patch will be far from perfect.

Waterproofing with roll materials is not universal. Thus, with their help it is impossible to process surfaces of complex shapes, for example, the underbody of a car. And even roll roof waterproofing can become a serious problem. In addition, high temperatures have a detrimental effect on this material and the degree of its adhesion to the base.

The main disadvantages of waterproofing with roll materials in specific conditions:

• Rolled roof waterproofing – impossibility of processing surfaces of complex shapes, long application process, susceptibility negative impact temperature changes, difficulty of maintenance
• Rolled floor waterproofing – poor perception of constant mechanical loads, especially in vibration conditions
• Rolled foundation waterproofing – instability to the negative effects of moving soils, additional load on the foundation, which is undesirable in areas with high levels groundwater and in loose soil foundations

Characteristics of basalt wool

If roll insulation for wallpaper, discussed above, is not suitable for you, then you can choose basalt or fiberglass wool, which has a wide application potential. It can be installed on walls or floors, as well as on ceiling spans. It is not recommended to use this material for sloping roofs, this is due to the fact that over time the mass slides and the insulation density is broken. If you want to use this flooring, you need to lay at least two layers. This will allow you to get 1 decimeter of thickness. If there is a need to insulate the walls, then half the amount should be used, and laying the material in one layer will be sufficient. If you want to achieve an effective heat-saving screen, then you should use similar thermal insulation with vapor and waterproofing.

What to consider when working

Insulation with mineral roll materials can be carried out at any time of the year, it is only important to ensure that the material is protected from precipitation. . The use of foam materials mounted on an adhesive layer depends on the air temperature

Usually the limit is down to –10C. Issued and special adhesives, effective down to –20C.

The use of foam materials mounted on an adhesive layer depends on the air temperature. Usually the limit is down to –10C. Special adhesives are also produced that are effective down to –20C.

Before insulation begins, minimal surface preparation is required:

• Dismantle pipes, electrical wiring, lamps, decorations, plants, etc.
• Clean the walls from remnants of old coatings, debris and dust.
• Install sheathing for mineral insulation.
• Level and clean the surface for gluing foam thermal insulators.

Installation does not require special equipment; the tools you will need are:

• construction knife;
• stapler;
• screwdriver;
• hammer;
• double sided tape.

It is more convenient to carry out installation and cutting of roll insulation together by two people, especially for large volumes of work. Small volumes can be done by one master.

Insulation process

The sequence of operations when installing mineral insulation is as follows:

• A vapor barrier film is attached to the prepared wall.
• A sheathing made of wooden blocks or metal profiles. The recommended guide pitch is 50 or 60 cm.
• Rolls are cut in accordance with the selected pitch. The cutting must be carried out so that the insulation fits tightly between the guides and, when straightened, provides a better fit to the guide.

Disc dowel

• Mineral wool is attached to the wall using disc-shaped plastic dowels, cut according to the thickness of the layer at the rate of 4-5 per square meter.
• The windproofing film is attached to the guides on top of the laid cotton wool. The joints of the film are sealed with double-sided tape. Installation of insulation on the walls of the house.
  Installation diagram under the sheathing

  Thermal insulation is complete. You can proceed to the installation of the selected cladding - wooden or vinyl siding. To ensure ventilation of the façade, a secondary sheathing of thin slats is installed on top of the wind barrier.

  Installation of roll foam insulation for external and interior walls in itself is simpler, but requires better surface preparation. It will have to be leveled more carefully - foam will not be able to hide unevenness as much as mineral wool.

  Fasten foam rolls with construction stapler not recommended - staples create so-called thermal bridges through which cold can penetrate into the warm part of the room. The thermal insulation effect of the material is somewhat reduced.

  How to fix insulation to the wall:

  • Clean and level the wall surface.
  • Cut the material for end-to-end installation.
  • In places of complex spatial shape - near openings, in corners, junctions of building structures (beams, balconies, etc.) it is better to try on the cut pieces before applying glue or removing the protective layer.
  • Apply glue to the heat insulator or remove the protective film from the adhesive layer.
  • Glue the material, moving from bottom to top.
  • Smooth the surface with your hands or a rule, achieving the best fit. If large air bubbles have formed, they should be carefully pierced in the center with a sharp needle and, moving from the edges of the bubble to the hole, squeeze out the air.

  After half an hour the glue will set and thermal insulation layer will be ready for use. When installing a cork sheet, glue specially designed for cork is used. It is applied both to the wall and to the cork. Before gluing wallpaper, you should wait until the glue has completely dried to avoid warping.

2 Rolled thermal insulation based on mineral wool

The quality of this category of insulation is regulated in accordance with the requirements of GOST RF “52953-2008”. This quality standard allows the following thermal insulation material to be classified as mineral wool insulation:

• Basalt wool is a material produced by melting rocks and the subsequent formation of microscopic fibers from them, connecting into a solid carpet;
• Slag wool is a material made from waste from the metallurgical industry. As a rule, it costs much less than basalt wool;
• Glass wool is a morally obsolete material, but still quite often used due to its low price. Produced by melting cullet.

Rolled basalt wool has a characteristic yellow tint

Rolled insulation based on mineral wool, due to its elasticity and flexibility, is an extremely versatile material that can be successfully used for thermal insulation of walls, floors, attics, and other flat surfaces, as well as for thermal insulation of pipes.

2.1 Mineral wool production

Let's look at the technology for making mineral wool using an example basalt insulation. Basalt rocks, the chemical composition of which meets GOST requirements, can be melted in two ways - hot and cold.

The hot method involves heating basalt rocks in blast furnaces, the cold method involves exposure electromagnetic radiation(based on the principle of a regular microwave).

The molten rock is fed into a centrifuge, which is equipped with constantly cooling carbide disks. Under pressure, molten basalt is fed into a centrifuge and falls onto rotating disks, where individual basalt fibers are formed from the melt through the process of cutting cooling and pressure drop.

The resulting fibers are immediately removed from the drum by a special functional element and supplied via a conveyor to a laying machine, which forms a carpet of basalt wool of the required thickness.

After laying the carpet, the fibers are impregnated with various impurities, which are necessary to give the final product the required characteristics - hydrophobicity, fire resistance, density and elasticity.

Slag material, as a rule, has a darkish tint

2.2 Advantages and disadvantages

Among all the thermal insulation materials on the market in the middle price category, it is mineral wool that has the lowest thermal conductivity. Although the leaders in general are polystyrene foam and mineral wool.

An important factor is that thermal insulation properties mineral wool do not depend in any way on any external conditions - this material does not expand under the influence of moisture, is not subject to thermal expansion, microorganisms and rodents do not grow in mineral wool.

Rolled mineral wool insulation is produced in a wide variety performance characteristics– you can choose either low-density mineral wool for insulating pipes and other uneven products, or dense material for thermal insulation of surfaces experiencing external loads– floor or attic floor.

An important advantage of mineral wool is its fire resistance. This material can withstand temperatures up to 700 degrees; it does not ignite even under direct exposure to fire. It is also worth noting good noise-reducing properties - by insulating walls and floors with rolled mineral wool, you will solve not only the issue of insulation, but also sound insulation of the house.

The only drawback of mineral wool is its high vapor conductivity, due to which the installation of a special vapor barrier film is required when installing this insulation.

Types and characteristics

Mineral wool insulation materials are widely used.

Their popularity is explained by their high operational and technical indicators and relatively low cost.

Roll insulation based on mineral wool includes:

1. . The material is obtained by melting rocks of a certain type and forming thin fibers.
2. Glass wool. Insulation made from molten broken glass, has an affordable price. Thanks to this, the material is in high demand, although it is considered obsolete.
3. Slag-like. The material is based on waste from the metallurgical industry, so it has a fairly low price.

Insulation based on mineral wool has its own distinctive properties:

• temperature resistance;
• low thermal conductivity;
• high density;
• absorption of vibrations and sound vibrations;
• no shrinkage after long-term use.

Foil roll insulation is made from expanded polystyrene foam by applying it to a layer of foil. The foil creates the effect of a thermos, pushing heat back into the room.

Expert advice: foil insulation can be used when installing infrared floors and for thermal insulation wooden saunas and baths.

The main properties of foil roll insulation include:

• high thermal insulation;
• reliable vapor barrier;
• good noise absorption;
• fire safety;
• durability.

Intercrown roll insulation is a rather specific solution. The main purpose is to fill the empty space between the crowns. Even high-quality assembly of houses from profiled timber or logs cannot guarantee a tight fit of the elements. An inter-crown heat insulator will fill the free space.

The material is produced in narrow rolls; natural and harmless materials such as linen, batting, and jute are used for its production. The use of this type of insulation is possible both during construction and during operation of the house. Everyone knows that over time, wood dries out, forming gaps between building elements. By filling the resulting voids with insulation using a chisel and mallet, you can retain maximum heat in the house.

Thermal insulators based on mineral wool

Materials in this group are most common in domestic market. This is due not only to their excellent operational and technical data, but also to an acceptable pricing policy - such a combination is so far unattainable for competitive offers.

Flexibility makes work easier

Assortment and features of species

The term “mineral wool” is a unified designation for a whole range of heat insulators, namely:

• basalt wool - for the production of this material, the technology of melting certain rocks is used, followed by the formation of the finest fibers on their basis, woven into a single carpet;
• glass wool is a material, although it is considered obsolete, but still has a fairly high demand due to its affordable cost. For its production, remelted broken glass is used;
• slag wool - it is based on waste obtained in the metallurgical industry. Due to this, such insulation in rolls has a lower cost than basalt and glass wool.

Each type of mineral wool has its own distinctive features and characteristics. Thus, glass wool perfectly resists high temperatures, up to 450 degrees - after exceeding this parameter, the material is destroyed irreversibly. The highest density is 130 kg/m3, thermal conductivity values ​​vary in the range of 0.038–0.046 W/m*C.

Glass wool in rolls

Glass wool is not flammable, it does not even smolder, it perfectly absorbs vibrations, resists sound vibrations and does not shrink even after long-term use. At the same time, the material is not moisture resistant, and getting it wet completely eliminates the entire range of positive characteristics. It is worth noting the fragility of glass wool, as well as the fact that contact with human skin causes severe itching.

As for basalt wool, such rolled thermal insulation can withstand temperatures up to 700 degrees. Its thermal conductivity is 0.035–0.045 W/m*C, and its density reaches 220 kg/m3. The material is resistant to moisture; slight wetting does not affect its parameters at all. Basalt wool is an environmentally friendly and non-irritating material.

Basalt wool

Slag wool has the largest mass, and its density reaches 400 kg/m3. The material is characterized by minimal thermal conductivity - 0.046–0.048 W/m*C, and the highest temperature it can withstand is 300 degrees - its increase causes melting of the slag wool and destruction of its structure.

Slag in rolls

The dimensions of the materials largely depend on the manufacturer, but most often they have the following standard sizes:

• length – varies between 3-6 m or more;
• width - standard 0.6 and 1.2 m, although products of individual brands may have a width of 1.22 m and 0.61 m;
• thickness – 50, 100 and 150 mm.

Wall mounting

Despite the fact that roll insulation is created from different materials, mount it on the wall according to the standard principle. All differences will lie in the composition of the glue that will be used, and, accordingly, in the drying time of the substrate on the wall.

Conditions for carrying out installation work with the substrate indoors

To glue insulation to the walls of your apartment, you have to do the following:

• First of all, it is worth preparing the surface, for which you need to remove the old wallpaper, plaster the wall, smoothing and sealing large cracks and irregularities. Small defects in the wall surface can be left, they will be closed.
• Next, the surface of the wall must be primed. This is done either using glue, which we will use to glue the substrate, diluted in a weaker consistency, or using a special primer composition. After priming, you need to wait until it is absorbed into the wall and dries.
• It is recommended to cut the rolled insulation into pieces of the required length in advance so that it can lie down and level out. This will make gluing it up a lot easier for us. When cutting the canvas, add a little material for insurance.
• We prepare the adhesive composition according to the instructions on its package. If we are dealing with a substrate with a top layer of paper, then we apply glue to the wall and to the cut pieces, and let them soak in the composition for literally 5 minutes. If the backing is equipped with non-woven edges, then it is enough to smear the wall, and the material will easily attach to it.

• Next, we proceed directly to installing the paintings on the walls. This process is reminiscent of wallpapering; the pieces are also glued together and carefully smoothed out. The air is expelled from under the canvas and it sticks firmly to the wall. It is convenient to use a rubber roller; it will create the necessary pressure and will not damage the insulation material.
• After the insulation has dried, after about 1-3 days, seal the joints of the panels with regular masking tape. Krepp will allow us to give solidity to our structure.
• Now our walls are well insulated, and we can proceed directly to gluing the wallpaper itself.

Wall insulation will allow us to create the most comfortable living conditions. It will serve us for a long time, no matter how long any wallpaper hangs.

The widely used thermal insulation boards have been replaced by roll insulation materials, which are more convenient and have improved functionality. Such products are suitable for finishing roofs, walls, engineering communications, ventilation shafts and other surfaces of complex shape. Rolled insulation has improved technical performance compared to mineral wool in slabs and is characterized by increased density and rigidity.

The flexibility of the insulation will help you complete the work of insulating your home in the shortest possible time.

Flexible thermal insulation in rolls

The material is affordable and has excellent performance properties. The scope of its application is renovation finishing and capital construction, when there is a need to increase the thermal insulation performance of surfaces:

• balcony;
• basement;
• gender;
• floors;
• attic.

Which insulation retains heat better:

There are roll-type insulation materials based on mineral wool, which are glued to the walls directly under the wallpaper. Their main purpose is to increase the temperature inside the room, reducing natural heat loss during the cold season. Additionally, such materials prevent the development of mold and mildew and the formation of high humidity. The uneven surface is perfectly masked due to the soft insulation, which does not require finishing work.

Characteristic features and differences of insulation:

The versatility of roll thermal insulation based on mineral wool determines a wide range of its use. . It is indispensable in modern construction industry , creates a durable working layer of insulation that protects from the cold:

• Living spaces;
• offices;
• warehouses at enterprises;
• outbuildings;
• baths and saunas.

Insulation, soundproofing of walls under wallpaper:

Soft thermal insulation is not damaged by regular contact with ventilation ducts and pipelines. Due to its sufficient flexibility, it covers tightly uneven surfaces, can be laid at sub-zero temperatures.

Material advantages

Thermal insulation in rolls designed to take into account the shortcomings, which characterize similar material in slabs. It has a number of positive aspects:

1. Minimization of thermal conductivity even among models belonging to the budget class.
2. A large assortment of roll insulation, the basis of which is various types of mineral wool. They differ in performance characteristics.
3. No damage from rodents, fungi, microorganisms.

1. Resistance to temperature changes, unfavorable atmospheric phenomena while maintaining the original thermal insulation properties.
2. Noise-reducing feature, resulting in increased sound insulation in the furnished room.
3. Resistance to open fire.
4. Easy installation that even an inexperienced craftsman can handle.

Like other universal materials, soft insulation has a drawback. They are characterized by increased vapor conductivity, which an additional layer of vapor barrier will help eliminate.

Main types and characteristics

The main component of the materials described is usually mineral wool. It, in turn, is presented in several versions:

1. Slag-like. The insulation is made from waste from the metallurgical industry. It is characterized by strength characteristics, while being the cheapest and most accessible product.

1. Basalt wool. The peculiarity of insulation in rolls for walls and other surfaces is that they are produced using rock melting technology. Then thin layers are formed from the resulting contents, woven into a single carpet.
2. Glass wool. The heat insulator is created from pre-melted broken glass. This approach to the production process significantly reduces the final price of the products described.

Each of the designated insulation materials has a specific set of characteristics. But in any case, they all represent an improved version of standard mineral wool. For example, glass wool exhibits excellent resistance to high temperatures: a heat insulator made from it can withstand up to +400°C. Exceeding this mark entails complete destruction of the material with the impossibility of restoration.

Which insulation is better:

As for the highest rates of thermal conductivity and density, they are typical specifically for roll insulation made of glass wool. It tolerates vibrations well, does not smolder or burn, and absorbs sound vibrations.

Throughout the entire service life, there is no shrinkage of such material.

Among the unpleasant aspects, irritation of human skin upon contact with fiberglass wool and slight instability to moisture are noted.

Thermal insulation rolls made of basalt wool also withstand high temperatures and are characterized by sufficient density and thermal conductivity. Excellent resistance to high humidity. Even when completely wet, the original quality indicators are maintained. This material is completely environmentally friendly, does not cause irritation upon direct contact, and does not cause allergic reactions.

The heat insulator made of slag wool can withstand temperature loads not exceeding +300°C. Otherwise, the slag melts and the structure of the described building product is completely destroyed.

Rolled thermal insulation materials differ in parameters and functionality. It all depends on the product brand, manufacturer, and buyer requirements when making a custom product.

The role of the foil surface

The main feature of such insulating devices is the presence of a thin but durable foil coating. In this way, the material is protected from the negative effects of ultraviolet rays and high humidity, which is very important when equipping industrial premises, kitchens, bathrooms, baths, saunas.

Laying of foil insulation is carried out in accordance with a special technological process. Between thermal insulation and finishing material a gap of 1−1.5 cm is necessarily created. This is very important, since at elevated temperatures the insulation maintains a given degree by transferring it to the back wall and then returning it back to the walls, but not to the room.

In comparison with rolled materials made of slag wool, glass wool and basalt base, the foil product must be fixed to the lathing. The layers are overlapped, and their joints are carefully treated with insulation.

Before buying soft thermal insulation for finishing a room for any purpose, you need to take into account some tips that experts share. The features and type of surface being treated are important, which can be brick, concrete, wood, etc. One should not lose sight of such an aspect as the thickness of the base when it comes to external insulation. In this case, the frequency and intensity of precipitation plays an important role, temperature regime by season.

Rolled heat insulation made from any type of mineral wool must be sold in undamaged packaging. Otherwise, moisture accumulates inside the material, worsening the quality of the product. When choosing the material to be described, its main functionality and purpose are taken into account.

Insulation in rolls is a popular finishing product. They are easy to use, improve the thermal insulation of premises for various purposes, maintaining it at the proper level for many years.

Knauf insulation:

When insulating large areas better efficiency They show not insulating boards, but rolls of insulation. The same applies to pipes and ventilation ducts. Their main difference is increased density, and a consequence of this is high rigidity of the coating, which allows for much better insulation of objects with non-standard geometry.

Features of the species

There are several types of insulation, mainly divided by composition.

Minvata

One of the most common thermal insulation materials on the Russian market is mineral wool. This is mainly due to a combination of price and technological properties of the material itself. It is very easy to use. It is advisable to choose a white, soft and self-adhesive material for the timber.

The name “mineral wool” is inherent in many thermal insulation materials that differ in their composition and properties. Not particularly popular is insulation, which is made by melting certain rocks to form certain fibers. During manufacturing, these fibers are woven into a single carpet; this wool is called “basalt”. Any resident of Russia and the CIS is familiar with the term “glass wool”.

This thermal insulation material is an outdated technology, but due to its price it is still in demand today. It is made by melting broken glass into single fibers. There is also cotton wool obtained by melting waste from the metallurgical industry (slag wool).

Due to the raw materials used in its manufacture, its price is much lower than that of glass wool or basalt wool.

Characteristics, pros and cons

Cotton wool differs from each other in technical characteristics. Glass wool has a high temperature threshold of 450 degrees, after which the material becomes irreversibly damaged. The density of glass wool is 130 kg/m3, and the thermal conductivity is about 0.04 W/m*C. This material is not flammable, it does not smolder, and has a high vibration and sound absorption threshold.

Over time, there is virtually no shrinkage, including options with long-term use.

The disadvantages include the fact that when water gets in, all the positive properties of this material disappear. Glass wool is a rather brittle and brittle material. Upon contact with skin, it causes irritation and itching, which is difficult to remove.

If it gets into the organs of vision, it can seriously harm them, as well as if it gets into the nasopharynx. You need to wear closed clothing when working with such material.

Basalt wool can withstand high temperatures (up to 710 degrees). Its thermal conductivity is about 0.04 W/m*C, density varies between 210 – 230 kg/m3. Unlike glass wool, this material is not afraid of moisture and does not lose its properties. When contacted with skin, roll insulation does not cause irritation or itching.

Slag wool has the greatest mass and density. Its density ranges from 390 to 410 kg/m3, and its thermal conductivity is about 0.047 W/m*C. However, its temperature maximum is much lower (about 300 degrees). The slag melts, and during the melting process its structure is destroyed, irreversibly.

The dimensions of these materials vary, depending on the manufacturer's established standards. However, the most common ones are:

• length from 3 to 6 m;
• standard width is 0.6 or 1.2 meters.

Some manufacturers make other width sizes (0.61 m). The thickness of the wool is standard (20, 50, 100 and 150 mm).

Foil material

Often one side of the insulation is covered with a layer of foil material. This allows you to protect the coating from moisture and ultraviolet rays. Most often, such materials are used for internal insulation premises, the cotton wool itself can be absolutely anything. The types of such material are varied. These include polystyrene foam, cork, and polyethylene.

The most popular material on the market is polystyrene foam. It is very practical and inexpensive. Copes perfectly with sound insulation and vibration. The length of the roll is usually 10 m, the width does not exceed 0.5 m. This material copes well with moisture and fungus. However, in terms of thermal insulation, it is significantly inferior to foamed polyethylene.

Thermal insulation with cork is characterized by high strength, low weight, harmlessness and good appearance. For wet rooms, it is recommended to use cork flooring with wax impregnation. The dimensions of this material are the same as those of expanded polystyrene. A fairly good material is foamed polyethylene. It consists of small cells filled with air, with cardboard or paper along the edges.

The substrate is secured by lamination. Due to this, it is possible to achieve the most durable and reliable connection with any type of base. Roll insulation has good thermal conductivity characteristics. Depending on the purpose, there are foil and metallized coatings.

For vapor reflection, a foil type of material is more suitable; for vapor containment, metallized spraying is required.

Spraying is very fragile and is damaged by small mechanical impacts. The foil material has excellent heat-reflecting characteristics. It is less susceptible to mechanical damage. Today, silver material with a reflector is quite popular.

Manufacturers and selection criteria

One of the leading companies producing roll insulation is a German company Knauf. A distinctive feature of the product is the absence of formaldehyde. In addition, the materials are characterized by ease of use. This company provides installation instructions for almost every roll, which will allow novice builders to do their insulation work better. Due to the composition, insects (beetles, ants) and rodents (rats) will not be able to settle in such thermal insulation.

The French brand is no less famous Isover. This company has a huge selection of roll-type insulation. Foil rolls are also available. The products of this company are used for insulating interior spaces, as well as outside buildings.

Due to its composition, it is fire-resistant; in the event of a fire or brief ignition, it does not support combustion and goes out on its own.

The most common company in the European part of Russia is the Spanish company URSA. Its products are somewhat cheaper than the French brand, the range is in no way inferior to it, which makes the materials in demand among buyers. The company provides a very long warranty on its products; it is better to check the exact warranty figures immediately before purchasing.

The cheapest insulation is produced by a domestic brand "TechnoNIKOL", which is aimed at middle-income people. The quality of this material is incomparable to foreign analogues, but the insulation is in great demand by people involved in their own construction of dachas or private houses. Due to the price, this is the favorite thermal insulation among management companies and other organizations that want to do something voluminous for little money. The mineral wool “Warm House” is also distinguished by its quality.

When purchasing, it is important to remember that different types of rooms require different insulation, just as ceiling insulation is highly undesirable when applied to the floor (and vice versa).

Wall insulation has its own characteristics, because the purpose of each type of insulation is slightly different, as are the properties. Some points also depend on the material of the structure on which the roll insulation is attached. It is necessary to look at how moisture affects the material in order to take this into account when choosing.

Installation technology

The technology for installing roll insulation is slightly different from slabs. They begin to insulate the walls or floor initially. The walls are mainly made of slabs, as is the straight ceiling. Therefore, often, floors and pitched ceilings-walls are suitable for insulation and installation. When insulating the floor, it is worth looking at what type of insulation is available.

Insulation in foil is mainly used, but sometimes rolls of insulation are covered with ordinary heat-insulating foil or metal film. The insulation should extend 1 cm away from the walls. This is due to the fact that when temperature changes, the material contracts and expands. The lack of free space in metallized or foil insulation leads to its deformation and damage over time.

Ceiling (pitched) insulation is attached between the rafters, cutting out a little more in order to insert it better between the boards. They are inserted strictly from bottom to top to avoid voids. After installation, the surfaces are clamped with main profiles or boards for application of additional (for example, vapor barrier) materials on top. The work is carried out especially carefully.

Wall insulation with roll insulation is most often used in cases where the wall area is significant and there are long straight spans. In this case, it is possible to achieve significant savings in material costs and performance compared to insulation in the form of slabs or mats. A variety of insulating materials are supplied in rolls, from mineral wool to pressed cork. Each of them has its own advantages in specific conditions. Installation of roll insulation is not a complicated operation and does not require highly qualified workers or expensive equipment.

Main types

Experts highlight following features and types of insulation supplied in rolls.

Based on material, insulation materials are divided into several types:

• Mineral (glass or slag wool). Typically used for external walls.
• Polymer - based on foamed plastics. Used to insulate walls from the inside and outside.
• Cork - from the pressed bark of the cork tree. Rolled cork insulation for interior walls is attached under the wallpaper.

Mineral and polymer roll insulation can be covered on one side with aluminum foil to reduce thermal conductivity and improve waterproofing. A thin layer of foil reflects over 95% thermal radiation, returning heat to the insulated room. Foil not only reflects heat well, but also increases the strength of the material.

Mineral basalt wool in roll

Characteristics

Rolled insulation materials are characterized by the following main parameters:

• Environmentally friendly. All models on the market must comply with safety requirements for installation, operation and disposal. They must contain small amounts of harmful substances; these substances must not be released from the insulation during its storage, installation and during use. The packaging indicates the disposal method. The materials are resistant to organic solvents and other active substances.
• Fire and bioprotection. Mineral insulation does not burn on its own and prevents the spread of flame. Foam materials can withstand fire for a certain time. The materials prevent the formation of mold and repel rodents.

• Air and vapor permeability. Key characteristics. They show how much air or water vapor at a certain temperature can leak through a unit area of ​​material. Vapor permeability is necessary in order to remove excess moisture from the room to the outside through the walls and their ventilation systems.
• Strength. An important characteristic of insulation under wallpaper. Touching, including with hard objects, should not damage the wallpaper.

Advantages and disadvantages

The main advantages of rolled material are:

• Versatility. Suitable for thermal insulation of any surfaces. For complex spatial shapes, including curved ones, you can cut out a suitable piece.
• Minimum requirements for surface preparation before installation.
• Benefits in terms of material price and work productivity when insulating large areas of walls, especially straight sections.

Roll materials have disadvantages.

• High labor intensity when laying in frequent lathing; additional time is required for cutting.
• Low rigidity does not allow them to be used where it is necessary to withstand significant loads.

In general, the advantages compensate for the disadvantages, which explains the high popularity of roll materials among consumers.

The materials are harmless to health provided they are used correctly and fire safety regulations are observed.

Popular brands

What to consider when working

Insulation with mineral roll materials can be carried out at any time of the year, it is only important to ensure that the material is protected from precipitation.

The use of foam materials mounted on an adhesive layer depends on the air temperature. Usually the limit is down to –10C. Special adhesives are also produced that are effective down to –20C.

Before insulation begins, minimal surface preparation is required:

• Dismantle pipes, electrical wiring, lamps, decorations, plants, etc.
• Clean the walls from remnants of old coatings, debris and dust.
• Install lathing for mineral insulation.
• Level and clean the surface for gluing foam thermal insulators.

Installation does not require special equipment; the tools you will need are:

• construction knife;
• stapler;
• screwdriver;
• hammer;
• double sided tape.

It is more convenient to carry out installation and cutting of roll insulation together by two people, especially for large volumes of work. Small volumes can be done by one master.

Insulation process

The sequence of operations when installing mineral insulation is as follows:

• A vapor barrier film is attached to the prepared wall.
• The sheathing is made of wooden bars or metal profiles. The recommended guide pitch is 50 or 60 cm.
• Rolls are cut in accordance with the selected pitch. The cutting must be carried out so that the insulation fits tightly between the guides and, when straightened, provides a better fit to the guide.

Hello, dear friends! When choosing thermal insulation materials for a residential building and outbuildings, you probably paid attention to roll insulation.

It is easy to use, its small thickness does not “steal” space, and the price in most cases is quite reasonable. Where and how can roll thermal insulation be used? What properties, advantages, disadvantages does it have? We'll tell you in this article.

Roll insulation refers to thermal insulation materials produced in rolls, based on expanded polystyrene foam or polyethylene. Now manufacturers are mastering the production of foam roll materials based on environmentally friendly natural raw materials, for example, rubber, balsa wood, cellulose.

Rolled heat insulators based on polymer materials are divided into two types:

1. Insulation in rolls with foil has high heat-retaining properties. The peculiarity of this type of insulation is that the layer of cellular polyethylene is covered with a layer of foil 0.5–2.0 mm. This material is resistant to high temperatures up to +180 C.
2. Conventional fine-porous insulation, produced in the form of rolls of various sizes. IN in this case There is no foil reflective layer.

There are also mineral-based roll insulation materials - these are mineral wool and basalt wool in rolls. In terms of properties and characteristics, these insulation materials are absolutely identical to ordinary mineral wool.

Thermal insulators in rolls based on foamed polymers have the following properties:

• high level of environmental safety;
• durability, not susceptible to rotting, exposure to rodents and insects;
• excellent heat-retaining properties with small thickness;
• low level of moisture absorption;
• good sound insulation;
• easy to install, can be cut into any parts and shapes without any problems.

Most thermal insulators in rolls have a self-adhesive base, which makes it possible to further simplify the insulation process and save on the purchase of adhesive composition.

Scope of application of roll insulation

Roll insulation materials are used for thermal insulation of vertical and horizontal surfaces. Foil material is indispensable for creating thermal insulation in bath rooms, as it retains heat well and has heat-reflecting properties. This material has also found wide application for thermal insulation of individual structures, joints, and in hard-to-reach places.

Let's look at the main ways to use rolled heat insulators.

Rolled thermal insulation for walls

Rolled wall insulation can be used as a heat-insulating material applied under decorative finishing, including wallpaper.

The application technology is very simple:

• self-adhesive material is glued to a wall that has been prepared in advance, leveled and cleared of debris and old finishes;
• A cement-based adhesive is applied to the heat insulator layer, its properties reminiscent of liquid plaster;
• After the adhesive has hardened, you can begin gluing the wallpaper.

The use of such material for wallpaper will significantly increase the heat-retaining properties of the walls, as well as their sound insulation.

Rolled floor insulation

It is used as a substrate for various types of decorative floor coverings. It not only has heat-insulating properties, but also gives the floor “softness”, eliminates squeaks and sounds when the floor covering shrinks and moves.

In some cases, a foil thermal insulator can be used to insulate the floor; this will increase heat retention; however, the cost of materials reinforced with foil is 30–60% more expensive.

The technology for performing floor insulation work using foamed polymer in rolls is very simple:

• the material is glued to a wooden floor or concrete screed using an adhesive composition or self-adhesive properties;
• leveled so that there are no “bubbles”;
• The floor covering is laid on top.

The advantages of such a heat insulator include ease of installation, lack of debris, durability and environmental safety. When choosing a roll insulation for the floor, it is worth remembering that the “softer” the floor covering, the denser the insulation should be.

In other words, it is better to use a polymer with maximum density under linoleum, otherwise when you walk you will “sink” into the floor covering, but under laminate or parquet you can lay a polymer with any density.

Rolled roof insulation

Suitable for thermal insulation of pitched and flat roofs. A roof insulated with such material will remain warm for several decades. You can install thermal insulation on your own, without involving highly paid specialists. The heat insulator is located between the elements of the roof rafter system, and distortions, the formation of waves and other defects are not allowed.

In some cases, for example, when insulating a residential attic space or in regions with a cold climate, it is recommended to lay the insulating polymer in two layers.

The technology for installing roof thermal insulation depends on the design features. The best option is when thermal insulation is calculated at the design stage. In this case, the work boils down to rolling out the rolled material and gluing it to the inner surface of the roof, laying a layer of vapor barrier material on top and installing the final finish, for example, siding, lining, etc.

Conclusion

Rolled polymer heat insulation is an excellent option for increasing heat retention indoors. It is easy to use, flexible, durable, and not expensive. Foil material is indispensable when insulating a bath or sauna, because it has reflective properties and is moisture resistant.
