What to use to attach the isoplat to the wall. Izoplat slabs for external cladding of a house - material properties and installation technology. Insulation of external walls under plaster

Reading time ≈ 4 minutes

Izoplat appeared on our construction market quite recently, but has already gained great popularity. This material is ideal for northern regions with harsh climate and severe frosts, as it has excellent thermal insulation abilities. In this article we will look at the basic properties of the material, its scope and installation features.

Isoplat building board is made from coniferous species wood and paraffin. The coniferous mass is pressed into slabs of a certain size and thoroughly impregnated with paraffin. The workpiece is then placed in drying chamber, where moisture is completely evaporated from it.

Technical characteristics of Isoplat

Obtained in this way Isoplaat slabs used for insulation of walls, floors and ceilings. The material is completely natural, environmentally friendly and has many other advantages. The main characteristics of the material are as follows:

• High heat-protective properties from cold and wind;
• Eco-friendly and breathable;
• Can be used in combination with other insulation materials, such as ecowool, etc.;
• Removes moisture from the room, prevents rotting processes and the formation of dampness and mold;
• Provides excellent sound insulation;
• Easy to install, cut and provides additional strength to structures;
• Long service life.

Izoplat soundproofing boards are available in thicknesses of 12 mm and 25 mm and respectively weigh 9 kg and 18 kg. The density of the material is 240 kg/m3. Isoplat provides sound insulation with noise absorption up to 26 dB. The service life of the material reaches fifty years or more.

Wall covering

Isoplat is widely used for interior decoration walls Due to its hypoallergenic properties and environmental friendliness, it can even be used to insulate children's rooms. Before installing Isoplaat, it is advisable to keep it in a warm room for several days in order to equalize the humidity levels of each slab. Then the material is puttied and primed. Joint areas are glued special tape. After this, the walls can be painted or decorated with wallpaper.

Isoplat can also be used for external cladding Houses. For fastening panels to concrete or brick materials glue is used special staff, which dries quickly and is resistant to adverse external conditions with high humidity and sub-zero temperatures. For additional fixation, facade dowels or screws can be used.

Isoplat can be used as an adhesive base for attaching Isoplat to external walls. polyurethane foam or drywall adhesive. The glue is applied in a layer about 10 mm thick. The sheets are attached to the wall at a distance of 12 mm from the floor surface and leveled. The seams are sealed with glue or foam. After complete drying, the resulting surface is primed or puttied. Then you can begin further facing work using any materials for decorating the facade.

The Izoplat windproof board significantly insulates the room and helps maintain a comfortable temperature in the house even in very coldy. This material can be used to insulate stone, wooden, brick and aerated concrete houses.

Underlay for laminate

Izoplat with sheet thicknesses of 5 mm, 6 mm and 7 mm is used as a substrate. An isoplat of this thickness provides sound insulation with sound absorption up to 22 dB. Installation of slabs to wooden surface made using construction staples, nails or special screws with flat heads. When making a substrate under the laminate, a distance of about 2 mm must be left between the Isoplat boards.

For attaching slabs to concrete floor you can use the same glue or foam as for cladding external walls. Isoplat panels provide acoustic comfort in the room, as they perfectly absorb the noise of footsteps. Coniferous substrate makes floors warmer and smoothes uneven surface bases for laminate or any other flooring. The laminate will lie perfectly flat and will not creak or sag under the weight of a person.

It is advisable to use such material when installing new floors or for restoration or insulation of old coverings. The panels do not emit hazardous toxic substances when burned or disposed of, they last a long time and can withstand significant loads.

Looking at the statistics of visits to the “Finnish house”, I noticed that people are actively interested in reviews of Izoplat windproof boards and about these boards in general :)

I have something to say about this and quite a lot.

Let's start with the fact that Estonian Isoplaat boards are MDVP (soft wood fiber board), also known as softboard. Such material is produced not only by Izoplat, but unfortunately, it is the only one that is more or less widely represented on the market in St. Petersburg and slightly less in Moscow (at the time of writing).

At one time, the production of MDVP began in Russia under the Softboard brand (Woodway company), but before it really started, production was curtailed in 2008 and, apparently, there are no plans to resume.

It's a pity. Because in principle, MDVP material is very interesting and good.

But let's return to Izoplat. There is a backing for the laminate, thermal insulation boards, roofing and windproof boards. By and large, it's all the same thing. The only difference is in size and in the fact that windproof and roofing slabs are impregnated with paraffin to give them hydrophobic properties.

The material itself is wood “wool” compressed and bonded (according to official versions) with a natural adhesive contained in cellulose - lignin. Therefore, the material can be called “environmentally friendly”.

There is some cunning of the manufacturer here, because it is quite difficult to make a slab with similar characteristics without binders, using only lignin. It would either be fragile (like pellets) or fall apart when wet and then dry. Therefore, I am 90% sure that there is still a binder, although manufacturers carefully hide its name and its presence in general. According to indirect evidence, this may be synthetic latex. Although this does not prevent the product from being called environmentally friendly.

Among the advantages of the material is a high degree of sound insulation (although in my opinion this is not so important, given the small thickness), as well as high thermal insulation (thermal conductivity coefficient at the level of modern insulation), high vapor permeability, and also, oddly enough - his "softness"

Isoplat - hard or soft?

The softness of an isoplat is a changeable thing.

if you look closely, you can see a “belly” on some sheets, like a wave

However, this “belly” partially disappears when the sheet dries.

In addition, after monitoring the information and talking with different knowledgeable people, I found out that the situation with the “belly” is typical for 12mm sheets. This no longer happens with 24mm.

Example 6

Dry isoplat can be cut perfectly with a regular knife with replaceable blades. It is very difficult to cut when wet. Rather, the plate begins to tear, rather than cut. It is very difficult to cut a wet slab with a knife.

Total:

Actually, what can you say? The softness of isoplaate directly depends on humidity. The wetter the material, the softer it is. But at the same time, it dries instantly and restores its original properties. In this regard, it is preferable to use a 24 mm sheet rather than a 12 mm sheet - which, frankly speaking, is completely “snotty”.

Does windproof isoplat provide rigidity to the frame?

One of the popular questions on the forums is whether isoplat gives rigidity to the frame and whether it can be used without jibs. There are different opinions.

I will express my opinion - yes, it can be used without jibs. But - 12mm only for a 1-storey building, if for a 2-storey building, then 24mm. In general, the question of the need for jibs together with an isoplat is quite specific and largely depends on the specific design of the wall.

Why do I think this? Firstly, while I was making the roof, and the frame was standing with temporary jibs, some “staggering” was felt. After sheathing with a 12mm slab and removing the temporary jibs, it’s gone.

Moreover, the box without internal walls, under the roof and only covered with 12mm isoplaat, stood completely calm from autumn until next summer. Although there was enough snow in the winter, and a couple of times there was even a stormy wind.

You must also understand that isoplat is not the only element that gives rigidity to the frame. In the future, interior decoration, exterior decoration, etc. will be added. I call this the “bun of arrows” principle. One arrow is easy to break, but a bunch is not.

So it is with the rigidity of the frame. Perhaps just a 12mm isoplate will not be enough. But in general, in combination with other layers of the wall, each of which makes its own contribution, the rigidity will be sufficient.

In addition, in my opinion, as paradoxical as it sounds, the softness of the windproof Isoplaat gives rigidity to the structure.

The fact is that due to its softness, the windproof plate is pressed very tightly against the racks

Stiffer boards (OSB, DSP, etc.) will not press this way precisely because they are rigid. Thus, it turns out that MDVP has a contact area with the frame and “adhesion” to it that is much better and denser than that of more rigid slabs.

Therefore, my conclusion is that in terms of rigidity, it is quite possible to use 12-24mm isoplats without jibs. But this will depend on the number of floors of the house, the windiness of the area and other layers of the wall.

Is it possible to leave the isoplat open for the winter?

Another popular question. Officially, the manufacturer writes something about 3 months. Unofficially, it sometimes stands for years, in Estonia. By and large, in terms of strength, nothing will happen to the stove if you leave it for the winter.

But there is an interesting nuance with which I have, let’s say, exclusive experience.

I sheathed the house at the end of August, when there were heavy rains, high atmospheric humidity and other delights. After a couple of weeks, I began to notice the appearance of black dots on the sheets, very unpleasantly reminiscent of “blackness” - mold that appears on boards and some slab materials. Photos were taken in winter

Interestingly, I installed a couple of sheets already in November, when I mothballed the house for the winter. So on these sheets, there were an order of magnitude fewer black dots.

Moreover, there were strange places with stains, where there was direct contact with moisture, and in the center of the stains - the slab was completely clean. And the points themselves are purely superficial.

It's like a blur. If you peel off the surface layer a little, everything underneath is clean.

On the right is a stove installed in November, it is almost clean. On the left - installed in August. The photo was taken at the end of spring, that is, more than six months later

Moreover, at its lowest point, the wall was covered with snow all winter. So, when the snow melted, all the “blackness” disappeared with it and did not appear again

the blackness was “washed away” by the melting snow

As you can understand, this situation really stressed me out, so I launched a whole investigation into this matter, including contacting the manufacturer and the dealer, using all the connections and channels available to me.

Unfortunately, I never got a clear answer from anyone. There is an opinion that it was not mold, but the release of a certain paint pigment under the influence of humidity. Because windproof boards are specially painted (that very green color) so that they can be distinguished from ordinary boards.

This version is supported by the strange nature of the “blurs” and the fact that in the last photo you can clearly see how a dark stripe runs over the top of the nail. In addition, all the blackness was exclusively on the outer, painted part of the slabs.

On the other hand, we should not forget that my site is practically in a swamp and given the constant high humidity, even those things that, in theory, should not mold, were often covered with mold and blackness - for example, pieces of FSF plywood.

In the end, just in case, before installing the imitation timber, just in case, I went over all the slabs with FBS antiseptic

I can also say that “colleagues” who also used windproof isoplaat on their houses and left them for a long period without external protection, nothing like this was noticed. Or it was, but in very small, local areas.

How to fasten and cut windproof boards?

• Nails with wide heads (tar paper) (40-70mm)
• Staples (35-60mm)

For 12mm slabs, the fastening pitch is 10cm at the edges and 20cm in the center. For 24mm - 20 at the edges and 30 in the center.

I attached it with 40mm tar paper nails. In principle it’s ok, but there are a couple of nuances.

Not all nails are created equal - in the photo below, the nails are from different batches, both of which were sold as "galvanized". This is what happened to them in six months

Good tar nails are for some reason a very expensive item. Even if you buy in bulk.

The amount of fasteners on a 12mm sheet is depressing. Both in terms of money and time. It took me almost 3 days to fasten all the slabs, and mostly it was just blunt waving of a hammer.

Therefore, I think that the best way is to fasten the boards with a pneumatic or electric stapler, a 40-50mm staple with a wide “back”.

In addition, I already wrote that I attached the slabs when it was humid and the slabs “swelled”.

In the spring, the slab dried out, the geometry changed and the slab around the fasteners broke in several places.

If you look closely, on the right sheet the plate is broken around the fastener

Hence the moral

1. Fastening with staples is faster and most likely more reliable
2. If you are attaching a “wet” sheet, do not leave a gap between the plates, it will appear on its own when the sheet dries
3. Do not attach the slab too close to the edge

You can cut slabs with anything. You can use a circular saw. But I didn't like it. A lot of nasty fine wood dust.

I cut with a regular construction knife with replaceable blades. The 12mm sheet is cut amazingly, although there are a couple of “buts”. Firstly, the blades get dull very quickly. Secondly, dry sheets cut well. Wet, starting to get shaggy.

Which windproof boards to choose?

Considering the rather low cost, the question often arises of which slabs to choose?

My opinion is that 24mm is best. They are more stable in size, they are easier to attach, and they provide greater rigidity to the frame. 12mm is an “economy option” that has certain disadvantages.

You can try an option that is more labor-intensive, but slightly cheaper than a 24 mm plate. Use a simple heat-insulating board as the first layer (it’s cheaper), and a wind-proof one as the second. This will save on the cost of the material, but not much.

But you can cover the joints of the first with a second layer, obtaining a more reliable structure.

In addition, you can splurge on roofing sheets (now called universal). They have a “tenon groove”, which allows them to be mounted horizontally, without being tied to the pitch of the racks and the size of the slabs. Which is important because there will be less waste. The slabs are laid one after another according to the laminate principle. The last piece in the first row is placed first in the second and so on. And the tenon groove does not create gaps at the joints.

Conclusion

What can I say in conclusion of my “review”? Would I use MDVP again - definitely yes. For me, this is an ideal material for the outer cladding of a frame. The only serious downside is the price.

After all, in normal countries, it costs 1.5-2 times cheaper than here.

Would I use Isoplaat if there were alternatives on the MDVP market? This is not a fact. I came across a Finnish Leon slab - subjectively it was less friable and more rigid than isoplaat. Unfortunately, supplies to our market were local and quickly stopped.

In particular, the Steico Universal cooker. What makes it different? Firstly, it is again denser than isoplat. Secondly, Steico Universal has a smaller sheet format and an excellent “tenon groove”, which allows it to be mounted like a laminate, without bothering at all with the slab joints getting onto the studs and with a minimum amount of scraps. A small sheet makes the installation process easier.

The problem of home insulation is especially pressing for our compatriots living in the harshest climatic conditions on the planet. Practice often shows that many advertised insulating materials simply cannot cope with our frosts in the form of use in which the manufacturer advises them to be used. But with isoplat everything is different; it really shows its effectiveness when used even in the Siberian climate.

The isoplat is based on compressed sawdust of coniferous wood. To turn sawdust into slabs, they are impregnated with paraffin, then placed in molds and dried. The factor that holds sawdust together is also the release of lignin from wood, which occurs during wetting and pressing.

The result is a slab that can be used in a number of areas of activity, allowing you to effectively insulate both walls and floors with ceilings. In the case of floors, this material is used as both an insulating and soundproofing component, and can be easily combined with laminate or screed.

This material has been known since Soviet times, and then the main direction of its use was floors, where isoplat was used to reduce noise levels. Since then, its scope of application has expanded significantly, and modern models of these sheets are widely used in frame construction, including in the Scandinavian countries.

Specifications

• Length – 2700 millimeters;
• Width – 1200 millimeters;
• Width – 12-25 millimeters;
• Weight – 9-18 kilograms;
• Density – approximately 260 kilograms per cubic meter;
• Heat capacity – 2100 J/kgK;
• Sound insulation coefficient – ​​26 dB.

Advantages of isoplat

• The material consists of one hundred percent natural components that are completely safe for health. Can be used for isolation in children's rooms;
• High insulating qualities that protect against cold and wind. The stove can be used in regions with the harshest climates;
• Izoplat can be used either individually or in combination with other insulating materials, such as mineral wool;
• In case of high humidity in the room, isoplat can draw excess moisture out, which helps normalize the microclimate and also prevents the formation of mold and mildew;
• Long service life. According to manufacturers, their product can last up to half a century or more. At the same time, over the years, the slabs do not lose their heat and sound insulation qualities;
• Easy to install. The plate is easy to cut with improvised tools, has a relatively low weight, and standard fastening materials can be used for its installation;
• Isoplat slabs allow for any type of finishing.

Important! You should not prime this material with conventional primers, since in this case the “breathing” qualities of the isoplat are greatly reduced.

Areas of application of isoplat

Wall covering

The technical characteristics of the material allow it to be used with equal efficiency in both internal and external wall cladding. In the case of interior work, experts recommend keeping the material for several days in the room where it will subsequently be installed, so that the isoplat “gets used” to the local microclimate.

Standard drywall adhesive is often used as a means of fixation to a brick or concrete wall. The gypsum-based composition is applied approximately a centimeter thick. It is necessary to install the slab not at the very level of the floor, but about a centimeter from its surface. After the glue has set, you can further strengthen the material with screws or dowels. Having leveled the material, you should use polyurethane foam along all the seams. By the way, the foam itself can be used as the main fastener, applying it along the perimeter of the sheet and in zigzags along its entire back side.

Lathing device

In addition to directly gluing the isoplat to the wall, the material can be mounted like plasterboard sheets - fixing it on a frame sheathing. For the latter, it is necessary to use wooden beams with sides of at least 45 millimeters. The bars are mounted at a distance of 30-60 centimeters from each other, depending on the thickness of the isoplat sheet. Fastening occurs with nails, which should be driven in increments of 15 centimeters around the perimeter and 30 centimeters along the internal parts of the sheet. In this case, after installation, the joints between the sheets and the heads of the fastening elements must be puttied.

Installation of slabs on the floor

As in the case of walls, you can mount the material either by directly gluing it to concrete or on joists (analogous to a frame). In the latter case, the same principles are used as in the case of lathing. Gluing is carried out with the same glue or foam as in the case of walls. Any method can serve as further finishing, but the most popular is laminate.

• On one side, the sheets of this insulating material are smooth, and on the other, wavy. It should be mounted so that the smooth side is on the outside;
• Work with isoplat sheets should be carried out in places with dry or normal air. Do not carry out work in places with high humidity;
• The horizontal joint of the slabs in the case of installation on a frame surface should be made exclusively on a horizontally located bar;
• In the case of frame installation, the wiring should be laid so that it does not interfere with the full fastening of materials to the wall, but is not damaged;
• When installing slabs on the ceiling, fasteners should be installed at half the pitch. It is also recommended to use nails with a wide head;
• Installation of sheets should be carried out after all “wet” work in the room that can increase humidity levels has been completed. An exception is the putty of the isoplat itself;
• If the sheets are slightly bent, which often happens with those located at the bottom of the pallet, they should be slightly wetted before installation, and then left for about a day on a flat surface.

Recently, a new material called isoplats has become increasingly popular. In essence, it is a simple windproof slab that is attached to the base of the building. It has a number of advantages. The most prominent ones include thermal insulation and sound insulation. That is, excess noise will not penetrate into the room and precious heat will not escape. In this article we will talk about the features of the material, its advantages and installation methods.

Application

Currently, isoplats are used to insulate all kinds of structures (ceilings, walls, etc.) and give them an interesting appearance. As a rule, they are made for the harsh northern climate. After all, it is here that a huge amount of winds and a humid climate are concentrated. As for the European part of the planet, slabs have been used here for quite a long time.

They are made from high-quality wood with the addition of all kinds of paraffins. This combination allows you to obtain very high-quality material that lasts for several years. After impregnation with paraffin, all structures are placed in a drying chamber. This is where the process of removing excess moisture occurs. It is worth noting that the isoplat contains no chemical additives. Due to this, many experts classify the slabs as environmentally friendly and natural.

Modern plates are used in the following areas:

1. Frame house construction. Here they serve as internal and external cladding.
2. Using them you can insulate houses made of stone, wood and aerated concrete.
3. Roofing materials are constructed on the basis of Isoplaat. It follows that the latter are used for the base layer of tiles and tin roofs.
4. Underfloor slabs are used both for repairing old floors and for laying new ones. They can be installed as a substrate under laminate or parquet. It is worth noting that the thickness should not exceed 5 millimeters. The new technology relates to good heat and sound insulation. Allows you to obtain a very high-quality and even floor.
5. They are also used to give an interesting appearance and protect the floor and ceiling.

Purpose

Also, do not forget about the purpose of such material:

1. To protect the house from wind blowing.
2. Removing excess moisture from the wall structure.
3. Increasing the total thickness of the thermal insulation layer.
4. Overlapping the cold bridge that runs along the frame posts.
5. Creating a sound-absorbing screen on all surfaces. Due to this, you will live in peace and quiet.
6. Protecting the walls of the house from all kinds of temperature changes and external irritants.
7. Load-bearing and enclosing element for insulation.

Advantages and disadvantages

Modern stoves have many advantages and several disadvantages. We will talk about each of them further.

Advantages:

1. Environmentally friendly. That is, they can be installed in almost any room, regardless of area and humidity. Besides, it doesn’t matter who will live here. The fact is that the new material does not cause all kinds of allergic reactions and other negative consequences.
2. Isoplat is very well protected from harmful weather conditions, including high humidity.
3. This material is not subject to rolling and exposure to wind. That is, after the installation is completed, you will not have to check its condition every day, which is very good. Isoplat can break the cold bridge in the frame base of the house.
4. The slabs can breathe, which extends their service life. It is worth noting that they also prevent the direct movement of air masses.
5. Capable of supporting soft thermal insulating material. One of these is ecowool.
6. Releases excess moisture out.
7. With a relatively small thickness, the thermal insulation of the room increases significantly.
8. The material can provide additional rigidity and strength to the structure.
9. Very easy to install, no additional experience required.
10. The material is very easy to cut with a simple knife.
11. They can protect from wind and moisture, and also last more than one year.

Flaws:

1. It is necessary to do the sheathing quickly.
2. High price.
3. Not available in every store.
4. If you do something wrong, you will have to redo everything.
5. The material is afraid of moisture.

Installation and assembly

Now we come to the most interesting and difficult part. The fact is that without special experience it is quite difficult to establish the foundation. Before starting work, the slabs must be left in the room so that the humidity levels out a little. If you don't do this, the end result will not be what you want to see.

Isoplates can be attached to a wooden structure using nails, screws, self-tapping screws and other devices. It is worth noting that it is necessary to install the new material with some clearance, approximately two millimeters. This is necessary so that during temperature changes the material can expand and contract. If this is not done, the plates may be damaged against each other.

If you have sheathing, then the isoplats must be secured with simple staples or nails. Experts recommend taking steps of 300 millimeters, or 600 millimeters. Typically this depends on the length and width of the slabs used. It is worth noting that nails should be driven in along the entire perimeter of the material at a distance of 10-15 centimeters from each other. This method allows you to avoid cracks and other troubles.

Windproof boards can be used not only for external cladding, but also for internal. If you want to finish the interior, you must adhere to certain standards. Before starting all work, the slabs are puttied and primed with a special material. All resulting joints must be sealed with special tape. Next, the surface can be covered with wallpaper or simply painted in the color you like. This already depends on the imagination of the builders and material capabilities.

If you want to fix the slab to a concrete or brick base, you should use glue and special screws for additional fixation. This allows time for the glue or façade dowel to dry. It is worth noting that glue can be of several types: glue for drywall, for thermal insulation, gypsum-based and polyurethane foam.

The glue should be applied in a layer no more than 5 centimeters wide and 10 millimeters thick. As for the polyurethane foam, it should be applied in a zigzag pattern.

Between the inner rows you need to leave 300 millimeters, but the distance from the edges should be 30 millimeters. If everything is done efficiently, the result will be good. Next, you need to lift the sheet and install it 10 millimeters above the floor. Press it against the main wall and level it with a level. This procedure is done over 15 minutes. Only after this can the resulting seams be filled with oil and foam. Further work should be done after the glue has completely dried.

After the adhesive base has dried, you can begin the final part of the installation. The surface can be finished with any materials and in any way. Before all this, it is recommended to prime or putty the surface. This process adds additional strength and durability. Only after this finishing is carried out in accordance with standards and methods.

Specifications

Separately, I would like to talk about some characteristics of the material. The quality and service life will depend on their values:

1. The thickness varies between 12-25 millimeters.
2. Width no more than 1200 millimeters.
3. The length is usually 2.7 centimeters.
4. The area of ​​the slab is 3.25 cubic meters.
5. Weight no more than 3 kilograms.
6. The weight of the plate itself is 9 kilograms.
7. Must withstand a bending load of 1.7 Newton per square millimeter.
8. The density of the material is more than 240 kilograms per cubic meter.
9. The maximum swelling is about 6 percent.

I would also like to note the number of basic materials:

1. About 95 percent wood.
2. Paraffin no more than 3.7 percent.
3. Aluminum sulfate 1.9 percent.
4. Sodium aluminate not more than 0.5 percent.

Review and cost

It is very easy to work with this material. It has many advantages that other materials do not have. If you want to preserve your health, then use isoplats. To buy one sheet with an area of ​​3.24 square meters, you will need 630 rubles.

Conclusion

And in conclusion, I would like to say that isoplat plates are very popular. THEY can be installed not only indoors, but also outdoors. This not only improves the appearance, but also provides protection from the wind.

What is Izoplat wood fiber insulation, how is it made, types of material, technical characteristics, pros, cons and features of do-it-yourself installation.

Description and production of wood fiber insulation

This material is produced using the technology of drying or pressing a wood-fiber “carpet”. In this case, wood waste is used - shavings, sawdust, etc. The ground raw materials are treated with water and folded into a “carpet”. After this, it is compacted under the influence of a press so that sheets are formed and lignin production begins.

If necessary, chemicals are introduced into the fiberboard composition that improve certain characteristics of the material. However, for gluing Izoplat boards, adhesives containing harmful phenol-formaldehyde compounds are not used. The fibers are connected to each other due to the natural resins that wood contains. The structure of the finished material is similar to felt.

Next, the material is dried for several hours. The finished slabs are shaped using a cutting machine. The standard size is 2700x1200 millimeters. Thickness can be 10, 12 and 25 millimeters. At the same time, one of the sides of the slab is smooth, which allows it to be used for fine finishing.

Wood fiber insulation Izoplat is a completely homogeneous natural sound and heat insulator. It has sufficient strength for frame house construction. Soft fiberboards occupy a leading position among windproof materials in the Baltic and Scandinavian countries. In addition, they are considered an alternative to drywall.

Isoplat is used both in residential buildings and in seasonal buildings (dachas, country houses). Also, for greater efficiency, it is used in multilayer structures as a sound-absorbing soft or lining material in combination with rigid sound-reflecting sheets.

Fiberboard insulation can be used to insulate roofs (usually logs), walls, ceilings, and floors. It is also used as a substrate for laminate or parquet, which is called “floating”. Isoplat is easy to process and saw, which guarantees an accurate fit of the slabs.

Main varieties of Isoplat

• Roofing slabs. They are used for installation under tiles on rafters. With their help, you can perfectly muffle the noise of precipitation and insulate the roof. The ends have a milled tongue and groove. The material is additionally impregnated with paraffin to achieve maximum non-hygroscopicity.
• Windproof boards. Suitable for sound and heat insulation of external surfaces under a ventilated facade. Impregnated with paraffin and completely waterproof. They are used, as a rule, for insulating wooden, frame, timber houses, as well as attics.
• Underlay for laminate. This type of Izoplat fiberboard is used for laying under parquet and laminate as an additional layer of insulation. The products are able to level out certain floor defects, and it is not necessary to use screed or plywood.
• Thermal and sound insulating boards Isoplaat. Their scope of use is the internal walls of the house, as well as ceilings. Most often, such boards are used instead of plasterboard sheets. They perfectly protect against the penetration of cold and extraneous noise. In addition, you can glue wallpaper directly onto them.

Technical characteristics of Isoplaat

1. Thermal conductivity. According to this indicator, the slabs are close to stone wool. The coefficient is 0.045 W/(m*K). The small thickness allows for economical use of space when insulating with this material.
2. Moisture resistance. Almost all products are treated with paraffin, which makes them non-hygroscopic and resistant to moisture. Even a small percentage of moisture absorbed by Isoplat will not worsen the thermal insulation characteristics of the material. The wood will accumulate moisture, but the interfiber space, which is responsible for thermal conductivity, will remain free of water.
3. Vapor permeability. Natural insulation allows the walls to “breathe”. It prevents condensation from accumulating on the surface, removing moisture out.
4. Soundproofing. The material is capable of absorbing from 23 to 26 decibels of acoustic noise.
5. Density. For Izoplat this figure is from 230 to 270 kilograms per cubic meter.
6. Compressive strength. The slabs have a value of about 200 kPa. This allows them to be used for insulating coatings under soft roofs.
7. Fire resistance. Universal Izoplat products comply with all fire safety standards. Despite the fact that wood is the raw material for their production, the special structure of the material prevents fire from spreading. When exposed to flame, ash will form on the surface of the insulation, blocking access to oxygen to the fire site.
8. Biological resistance. During the production of boards, wood is deprived of components such as starch and sugar, which serve as food for microorganisms. Therefore, mold, rot and fungi will not appear on the insulation.
9. Environmental friendliness. In the manufacturing process of this heat insulator, no harmful chemicals or glue are used. Therefore, the material will not emit volatile compounds during installation and during use.
10. Lifetime. The manufacturer sets a warranty period for slabs of 50 years. If installed correctly, Izoplat can be used longer.

Advantages of Izoplat plates

• Environmentally friendly insulation. The raw material for Isoplat is wood. There are no binders in the composition; the fibers are intertwined naturally and held together with natural resins. Therefore, it is important to use such material for insulating wooden eco-houses, as well as rooms where children and allergy sufferers live.
• Excellent vapor permeability. Isoplat is able to regulate the humidity state inside the building and create a favorable microclimate.
• High thermal inertia. The plates are capable of accumulating and releasing heat for 14 hours. Thus, the temperature inside the building is stabilized. Temperature fluctuations will not be felt as much when it decreases or increases outside the room.
• Not subject to shrinkage or destruction. Unlike a large number of synthetic insulation materials, fiberboards do not shrink or deform over time.
• Windproof abilities. Izoplat slabs can also be installed as wind protection. The fiber is located inside the material in layers, along which air pores are randomly concentrated. Getting into the space between the fibers, the outside air loses pressure and speed.
• Filtration properties. Isoplat, due to its structure, is able to retain harmful compounds. This is especially true when using slabs in structures with insulation materials such as polystyrene foam, mineral wool, which can emit formaldehyde, styrene and other toxic chemicals.
• Easy to install. To install the products, you do not need special equipment. All work can be done by yourself. The convenient tongue-and-groove system greatly simplifies the installation process.

Disadvantages of Izoplat fiberboards

• Increased softness when exposed to moisture. If the material is exposed to water or humid air for a long time, it will become softer. However, when it dries, it will regain its strength and shape.
• Relatively high price. Natural materials tend to be more expensive. Izoplat is no exception. Therefore, it will cost an order of magnitude more than artificial insulation.

Price and manufacturer of Izoplat plates

The price of fibreboard insulation can vary depending on its type. The average cost in Russia is:

1. Thermal and sound insulating board Izoplat - from 200 to 500 rubles per square meter;
2. Windproof board Izoplat - from 290 to 1150 rubles per square;
3. Thermal insulating substrate for Isoplat laminate - from 115 to 200 rubles per square meter;
4. Izoplat facade slabs - from 1000 to 1200 rubles per square.

Brief instructions for installing Izoplat insulation

The tools you will need are construction staples or flat head screws, a knife, a building level, a hammer or a screwdriver.

Isoplaat boards can be installed on pre-installed sheathing or glued directly to the wall surface.

We work according to this scheme:

• If you decide to make lathing, then its pitch should be from 30 to 60 centimeters, depending on the thickness of the slab.
• For fastening to concrete and brick surfaces, you can use various types of glue - for thermal insulation, gypsum-based, plasterboard, as well as polyurethane foam.
• Apply glue to the rough surface of the product in stripes or dots around the perimeter. We press the insulation to the surface.
• Self-tapping screws or nails when attaching slabs to the sheathing must be flush with the surface and not protrude above the insulation.
• We seal the fastening points with putty.
• If you fixed the slabs with glue, then before decorative finishing it is recommended to go over them twice with glue or primer (if you plan to paint).
