How to insulate the ceiling on the veranda of a house. How to insulate a veranda: do-it-yourself technology. Insulating veranda walls - several inexpensive ways

In conditions harsh climate The owners are trying in every possible way to insulate their house or cottage. For example, to protect front door they put up a veranda. This is a kind of vestibule where the mixing of cold street air and warm air from interior spaces. But when insulating a house, they do not always take into account that the veranda could use additional insulation. Otherwise, the unheated room will freeze and become damp, causing the finishing to quickly deteriorate. With the right approach, the veranda is insulated during the construction stage. But it happens that the house was not built, but bought, and not in the very at its best. In this case, insulation of the veranda from the inside is carried out with your own hands as necessary. The main thing is to know in what places the cold “creeps” into the room and take all possible protective measures.

Usually the veranda is placed on the same type of foundation as the main building - monolithic concrete or concrete plates. This material does not block the cold that comes from the ground in winter at all, so it can freeze through. Heat loss through the foundation reaches 20%.

There may be several options for how to insulate the base of a summer veranda.

Filling the interior with earth or expanded clay

These options are only possible at the stage of constructing the veranda, when foundation work is underway. After removing the formwork, the entire internal area is covered with earth or expanded clay. Land will be cheap, especially if there is a lot left during construction excess soil. True, its heat saving quality is low.

Expanded clay layer prevents moisture and frost from penetrating into the concrete slab

Expanded clay has higher thermal insulation, but you will have to buy it. You can make a double layer: first fill it with soil, and the second half with expanded clay pebbles.

Pasting with polystyrene foam

For Russian lands, where 80% of the soil is heaving, external insulation of the foundation with expanded polystyrene is necessary. When thawing and freezing, such soils expand in volume and can deform the foundation. The insulation layer will become an insulator, which will relieve the base from direct contact with the ground, and will also block frost. Expanded polystyrene boards cover the entire outer surface concrete, including plinth.

For insulating a veranda with your own hands, the following are suitable: polystyrene foam, extruded polystyrene foam and liquid polyurethane foam. All these are varieties of polystyrene, which differ in properties and method of application. The cheapest one - Styrofoam. It retains heat well, but will crack on moving soils. In addition, polystyrene foam draws moisture from the ground, so when installing it, an additional waterproofing layer is created (from the soil). Extruded polystyrene foam Due to its dense structure, it does not absorb moisture, is not afraid of soil movements, has high frost resistance and lasts for more than half a century. But it is expensive.

Before gluing expanded polystyrene, it is necessary to cover the entire foundation with waterproofing mastic

Both versions of polystyrene are laid with outside foundation, excavating it to its very foundation. In this case, the first row is placed on a gravel bed. Before laying, the foundation is coated with bitumen-polymer mastic (for waterproofing), and when it dries, polystyrene foam boards are glued on. The glue must be polyurethane. It is applied in dots or by smearing the entire sheet. The joints between the plates are also glued so that there are no cold bridges and cracks for moisture penetration.

The newest method of external insulation is polyurethane foam spraying. It is brought to the construction site in the form of liquid components and sprayed onto the foundation using special equipment. After hardening, the coating becomes dense, monolithic and very durable. In terms of characteristics, this material is not inferior to its extruded “brother”, but the cost of work is more expensive.

With sprayed insulation, the most best quality thermal insulation because there are no joints

To keep your feet from getting cold: floor insulation

Besides the foundation, the floor is closest to the ground. Its insulation is mandatory if you do not want to see black spots of dampness in the corners.

Most often, concrete floors are poured on verandas. If you plan to heat the veranda using a “warm floor” system, then you should take care of it already at the stage of pouring the subfloors. It's best to choose an electrical system that you can turn on as needed. A water floor can be very low temperatures freeze, and you will have to wait until spring for it to thaw, or dismantle the coating to warm up the pipes.

If you were lying on the veranda old tiles, then you can put the insulation directly on it

Let's look at how you can insulate the floor on an unheated veranda:

1. The entire underground floor is covered with crushed stone, and on top - with sand and compacted tightly.
2. Lay out reinforcing bars or mesh (so that the concrete does not burst) and make concrete screed 5 cm thick.
3. When the filling is dry, we create waterproofing. The easiest way is to coat the screed with water-repellent mastic. But it’s cheaper to lay sheets of roofing felt and fasten them together using bitumen mastic (or heat them with a burner and roll them).
4. Antiseptic-impregnated logs are installed on top of the waterproofing, and insulation is laid between them. Most best option – mineral wool with foil side. Foil does not let you out of the veranda infrared radiation, along with which most of the heat evaporates. Rolls of insulation are placed after all the joists are installed.
5. It can also be insulated with polystyrene foam. Then the joints between the plates must be blown out with polyurethane foam, and when it dries, the excess must be cut off.

After this, planks or decking are laid, because both materials are warm. The board must be treated in every possible way to prevent rotting and painted. protective composition. Besides, natural wood very afraid of poor ventilation. To avoid dampness, it is necessary to do in the foundation ventilation vents, which should be located below floor level.

The insulation is placed with the foil facing up so that it reflects the heat back into the veranda

Decking does not require ventilation in the underground, because it is not afraid of dampness and temperature changes

Decking is also a board, but already treated with compounds at the factory. It is made from larch, which is not afraid of either frost or moisture. This material is used to line open terraces, so it’s even more suitable for the veranda. True, the cost of such a floor will not be cheap.

We install thermal protection for the walls

At the walls big square contact with the street, so let’s look at how to insulate a veranda with your own hands from the outside and inside. External insulation is carried out if the wall material looks unpresentable. Those. it could be blocks, old wood, etc.

External insulation

a) For wooden walls:

1. We seal all the cracks in the building.
2. We place a vertical sheathing of beams on the tree in increments of up to half a meter. It is better to measure the width of the insulation and fill it exactly to its size. Then all the slabs will fit tightly to the sheathing.
3. We insert mineral wool between the beams, securing them with dowel umbrellas.
4. We fix the waterproofing film on top with a stapler.
5. We finish with clapboard or siding.

After laying the mineral wool, you need to staple the waterproofing film to the sheathing

b) For block walls:

1. We glue polystyrene foam boards to the walls with a special adhesive composition, additionally strengthening them with dowel umbrellas.
2. We smear the same glue on the top of the slabs and attach the reinforcing mesh to them.
3. After drying, cover the walls with decorative plaster.
4. Let's paint.

Pick up adhesive composition specifically for laying polystyrene foam boards

All layers of the insulation cake are hidden under decorative plaster

Let's insulate ourselves from the inside

If the veranda looks aesthetically pleasing from the outside and you do not want to change it appearance, then you can carry out internal insulation. But, before you insulate the veranda from the inside, you need to carefully caulk all the cracks (in a wooden building).

Work progress:

1. They stuff the sheathing.
2. Fix the waterproofing film with a stapler, which will prevent moisture from the street from entering the insulation.
3. Mount metal carcass from profiles onto which drywall will then be attached.
4. Fill the frame with mineral wool.
5. Cover the insulation with a vapor barrier film.
6. Installing drywall.
7. Apply the finishing coat (putty, paint).

The distance between the metal profiles must match the width of the insulation sheets

We check the tightness of the installation of windows and doors

Large heat losses can come from windows and doors. If there are old ones on your veranda wooden windows, but you do not want to replace them with double-glazed windows, then you need to thoroughly check their tightness:

• First of all, we pay attention to the quality of the glazing of the veranda: to do this, we pull each glazing bead.
• If they are cracked or loose, it is better to remove all the glass, clean the grooves and coat them with silicone sealant.
• Then we insert the glass back and apply sealant around the edge.
• We press with glazing beads (new!).

Go over the joints of the frame and the window opening with a regular metal ruler. If in some places it passes freely, then these cracks must be sealed with polyurethane foam. Check the front door in the same way. If you bought an uninsulated option, you will have to insulate the canvas yourself inside and upholster with leatherette.

Seal the glass on both sides with sealant to make it windproof

All places where the ruler moves freely must be foamed

Eliminate leakage of warm air through the ceiling

It remains to figure out how to insulate the ceiling, because through it wooden veranda a significant part of the heat evaporates. Especially if the front door opens. The flow of cold air rushing inward instantly squeezes the warm air upward.

Most the best option– place foil-coated foam polymer between the beams, which will simultaneously retain heat and keep moisture out.

You can also choose mineral wool, but then the first layer is roofing felt for vapor barrier, and insulation boards are placed on it.

Ruberoid is laid under mineral wool for waterproofing

After such careful insulation, your veranda will withstand any frost, even if it is unheated.

Veranda - beautiful place for relaxation, family tea parties and friendly gatherings. In the warm season, the terrace becomes the most popular part of the house and a great opportunity to gather dear people together. However, with the onset of cold weather, the idyll ends - no one wants to sit on a cold veranda. But the situation can be easily corrected - all you need to know is how to properly insulate the veranda. By the way, proper insulation will not only preserve the usual comfort, but will also help protect the corners of the extension from the formation of black spots that occur under the influence of low temperatures.

What is the best way to insulate a veranda?

The range of thermal insulation materials is quite wide, so the selection process remains more relevant than ever. Meanwhile, there are samples that have proven themselves best. These are the ones you should give preference to when purchasing.

The leaders in the number of positive reviews are mineral wool and polystyrene foam. A profitable way to insulate a terrace, and even save a significant amount. To improve the created effect, a foam pad is used. Metallized sheets reflect cold street air and prevent precious heat from escaping. Penofol is a high-tech heat insulator consisting of foamed polyethylene covered with aluminum foil. This material can be used both in tandem with other thermal insulators and alone. Of course, the first option is more effective, because allows you to use the benefits of protective raw materials to the maximum.

How to insulate a wooden veranda?

The problem is how to insulate cold veranda starts to worry owners country cottages with the onset of the first frost. Will you really have to leave the tradition of relaxing on the terrace until spring? Not at all - warm yourself up and continue enjoying life!

Tools and building materials

• insulation (penofol, mineral wool, expanded polystyrene, etc.);
• polystyrene foam (thickness at least 10 cm);
• nails, hammer, nail gauge;
• scissors, hacksaw;
• tape measure, pencil;
• scotch;
• paint, brushes;
• putty knife.

We insulate the floor

If you are thinking about how to insulate a plank veranda, but don’t know where to start, then experts advise that the first step is to protect the floor. Some people mistakenly believe that it is not necessary to insulate floors and that you can limit yourself to just the walls and ceiling, but this opinion does not correspond to reality. If there is no continuous foundation strip, then the question of how to insulate the floor on the veranda takes on a different meaning. Defining.

The seams between the boards are puttied, then painted and punched with penofol on the underside. The inside of the floor can be insulated with polypropylene-based linoleum or felt-based carpet. Arranging a second floor is considered a more complex, but also more reliable method. It is used as a rough draft, followed by installation of thermal insulation and finishing coating. The only thing, keep in mind that this will significantly reduce the ceiling height.

How to insulate walls?

How to insulate a veranda from the inside? If this problem is relevant to you, then get ready for the fact that you will have to completely replace the wall cladding. The boards are removed using a nail gun. To prevent the tool from leaving marks, place a piece of cardboard under it. The more carefully you remove the old boards, the easier it will be to install new ones. One of the most simple solutions- attach insulation with a foil layer (10-15 mm thick) to wooden brackets, and finish the walls with MDF panels on top.

If the walls are brick, then it is necessary to make a sheathing of transverse wooden beams with a section of 25x40 mm. Insulation in in this case thicker is used - 25-30 mm. It must be cut into strips and laid between the beams. There should be no gaps.

The following method is no less popular. After carefully measuring the area, penofol is cut into pieces of the appropriate size. Leave a couple of centimeters at the top and bottom for folding. Cover the walls with material and secure the edges with tape. Next, polystyrene foam is laid on top of the penofol. The panels should fit together as tightly as possible. In narrow, hard to reach places you will inevitably need pieces non-standard forms and sizes that can be cut using an ordinary hacksaw.

Nail the trim. If the thickness of the insulation is chosen correctly, then the boards will not bend and will “sit” perfectly. The final stage is painting the trim and replacing the ceiling plinth.

How to insulate the ceiling on the veranda?

A hydraulic barrier is mounted on the ceiling, then the surface is sheathed with 27x27 mm timber. The gaps between the beams depend on the thickness of the insulation, but it is not recommended to leave intervals greater than 0.8 mm. The hydrobarrier is attached horizontally, the seams are glued together with metal tape. Sheathing beams are nailed vertically.

Penoplex sheets are inserted between the bars and secured with wide-headed dowels. A heat reflector is placed on top of the penoplex, for example, Ecofol (foamed polyethylene covered with a lavsan metallized film). The heat reflector is temporarily secured using a stapler. Later he is pinned down by a blockhouse. The blockhouse is installed in concentric rows, which is necessary to create a perfectly flat surface.

The blockhouse can be replaced with clapboard or OSB. When carrying out work, use only serviceable tools, remember the protective equipment (mask, gloves). If you spray foam, ventilate the room from time to time.

How to insulate a summer veranda?

If the veranda is not in the house, but is an extension, this does not mean that insulation is impossible. If you have a canopy or roof, this is quite possible.

You should start again from the floor. Along the perimeter of the veranda, paved with concrete or stone, a small fence made of building blocks or bricks is laid. Then the floor is covered with two layers of roofing felt, which will simultaneously serve as a hydro- and vapor barrier. The selected insulation is laid on top (layer thickness - 10 cm), then a vapor barrier membrane and finishing coating are laid.

The next step is double-glazed windows placed right under the roof. The roof is insulated according to the “pie” type: waterproofing film on rafters, insulation, vapor barrier, decorative coating.

Terrace with wooden floors It is insulated somewhat differently. The floors are opened and insulation is laid between the joists. However, it is necessary to lay waterproofing under it, because... in this case, there is usually no foundation under the summer veranda. A timber fence is installed around the perimeter, which is used as a basis for double-glazed windows.

Features of insulation from the outside

If you have recently made repairs and don’t want to start construction work all over again, you can insulate the veranda from the outside. This will provide a wonderful opportunity to refine the façade and give the building a modern look.

The sheathing is attached horizontally or vertically to the walls. The intervals between the guides are filled with insulation and moisture insulation. The cladding is attached last, for example, metal siding or decorative panels, finished with powder coated honey.

Now you know how to insulate a veranda, which means your home will always be cozy and comfortable. Even on the chilliest autumn evenings, spring will reign on the terrace and good mood!

Video: how to insulate a veranda

The idea of ​​adding a veranda to your country house is quite rational, but it is not enough to just put a foundation and build a box on it - you need to think about thermal insulation. An uninsulated veranda will very quickly become unusable, and you will feel discomfort with the onset of the first cold weather - condensation will appear on the walls, and it will be replaced by black mold and mildew. To prevent this from happening, you should provide protection for the walls, floor and ceiling. This is what will be discussed in our article.

Today on the market you can find scary a large number of a wide variety of thermal insulation materials for every taste and budget. In most cases, thrifty owners give preference to polystyrene foam or mineral wool - they are inexpensive and retain heat well. But when using, say, polystyrene foam, you should remember the measures fire safety– it does not burn, but melts, releasing toxic black smoke. Therefore, if you are planning to organize a kitchen on the veranda, it is better to refrain from insulating it with foam plastic.

As additional insulation A foam pad is used. Thanks to its metallized layer, penofol perfectly reflects ultraviolet radiation from the outside, thereby keeping the room cool in summer and warm in winter. Penofol consists of a layer of foamed polyethylene and a layer of durable aluminum foil. It can be used as additional or completely independent thermal insulation, but to achieve maximum effect it is recommended to combine it with other materials, for example, polystyrene foam or polyurethane foam.

Polyurethane foam is also inexpensive and effective material for thermal insulation of residential premises. It is not subject to combustion and exhibits excellent results even at very low temperatures.

Foundation insulation

The veranda is not only an additional living space where you can relax or receive guests, but also a kind of buffer zone for the main home. During the cold season, it provides additional thermal insulation for the front door. Therefore, the better the veranda is protected from the cold, the warmer the house itself will be in winter.

It is necessary to start insulating the veranda from the very base - from the foundation. In general, this should be taken care of during its laying, but if the moment is missed, there is a way to fix everything. The most important thing is to know where the main “loopholes” for cold flows are located and act purposefully.

Usually the veranda is built on the same type of foundation as the main house - concrete slabs or monolithic strip foundation. Despite the reliability of the structure, concrete does not at all prevent the penetration of cold that comes from underground, so the foundation and the house built on it can freeze thoroughly. It has been proven that up to 25% of heat escapes through an uninsulated foundation.

There are several options for insulating a veranda with your own hands. You can fill the space between the foundation segments with soil or expanded clay, but this is only possible when building a veranda, otherwise you will have to dismantle the floor to the base. Filling with earth will be cheaper, but it retains heat much worse than expanded clay (foamed clay). To save money and get good results, many people combine insulation materials, alternating layers of earth and expanded clay.

Pasting with polystyrene foam

Most of the territory of Russia is covered with heaving soils, so the foundation built on them requires additional strengthening and insulation. To do this, the outside is covered with polystyrene foam. This material is a reliable insulator that prevents the foundation from direct contact with the ground during expansion (swelling), maintaining its integrity and strength. Expanded polystyrene is sold in large slabs, which should be used to cover the entire surface of the foundation from the outside, not forgetting to protect the base.

Polystyrene foam and liquid polyurethane foam are types of polystyrene foam and differ in price and operational characteristics. Foam plastic is the most a budget option insulation. It retains heat well indoors, but is not suitable for highly mobile soil (it will crack and crumble over time). The main disadvantage of polystyrene foam is its ability to take moisture from the ground, so if you are planning to make such thermal insulation, you should take care of good waterproofing layer, otherwise on next year you'll have to start all over again.

Another thing is extruded polystyrene foam. It does not absorb moisture and is suitable for heaving soils, has excellent frost resistance and can last about 50 years. The only drawback is the impressive cost, but in this matter it is better not to skimp on quality, especially if you are building a veranda for the house in which you live permanently.

To reinforce with polystyrene foam or polystyrene foam, you should excavate the foundation to the ground. The first row of material must be placed on a gravel bed, having previously coated the foundation bitumen mastic(waterproofing). After the mastic has dried, you can glue the slabs using a special polyurethane foam adhesive, which is applied spotwise or spread over the entire slab. The joints between the materials should also be glued to eliminate the risk of cold bridges.

Polyurethane foam spraying is in the newest way insulation of foundations. This requires special spraying equipment and professional skills. The good thing about this method is that it allows you to very quickly create 100% thermal insulation of any foundation or wall. Having hardened, the material becomes very strong and durable, however, the cost of such insulation will be much higher than pasting with slabs.

Floor insulation

When the foundation insulation work is completed, it is time to work on the floor. This is a mandatory step, which determines whether you will enjoy seeing black mold in the corners or not.

If you are planning to pour concrete on the veranda and plan to heat it using a “warm floor”, you should take care of everything at the stage of working with the subfloor. Give preference electrical systems, which can be turned on as needed and adjust the temperature. This way you will save impressive amounts on electricity.

The area of ​​the walls is the largest compared to the ceiling or floor, so they require thorough insulation. Fortunately, this is no more difficult to do than with the floor. The only “stumbling block” that most inexperienced self-taught builders have is whether to insulate the walls from the outside or the inside? Opinions on this matter differ, since each situation is individual and depends on climatic conditions, the material from which the walls are made, the type of insulation, the thickness of the walls, etc. Finding out all this can take a very long time, but if you want to get a 100% result, it is recommended to do insulation on both sides.

The image below very clearly shows how heat loss occurs when different types insulation:

Insulation from outside

Insulation should begin in the spring, when all the snow has melted and you can work for a long time on fresh air With various solutions And construction mixtures. From the outside, the veranda can be insulated with polystyrene foam or polystyrene foam using special fasteners - “mushrooms”. This is a special type of fastener that distributes the load of the slab, ensures its tight fit to the wall and ventilation.

It is recommended to pre-treat the wall with protective mixtures against fungi and dampness, then glue the “mushrooms” and slabs of expanded polystyrene or polystyrene on them. A fixing mesh is placed on the slabs, and plaster can be applied on top of it and the finishing of the facade can begin.

Finishing can be done using various plaster compositions. You can learn more about which plaster to choose and how to work with it in the article.

There are other insulation technologies, for example, combining polystyrene foam with a vapor barrier and finishing the facade with siding, or using an insulating film and a block house. In this case, you should focus on the amount you plan to spend.

Insulation from the inside

Insulating the veranda from the inside will help achieve best result and preserve precious warmth in the house. When you're done with external finishing, you can move inside and properly work with the walls.

How does internal wall insulation occur:

1. Caulk all the cracks if you have a wooden veranda.
2. Stuff the sheathing from wooden slats.
3. With help construction stapler fix the waterproofing film to protect the insulation from moisture from the street.
4. Attach the metal profile frame.
5. Lay drywall into the frame and fill the space with mineral wool or any other insulation material of your choice.
6. Cover the insulation with a layer of drywall.
7. Apply topcoat.

In this case, drywall provides a perfectly flat wall surface, on which wallpaper, putty, paint or even artistic painting will perfectly fit.

Ceiling insulation

If you have even a superficial understanding of air circulation, then it should be obvious to you that almost as much heat escapes through the ceiling as through the floor. An uninsulated ceiling will negate all work to retain heat inside the room and will also create ideal conditions for condensation to form, which will lead to mold and mildew.

It is best to insulate the veranda ceiling with foil foam polymer material, which will simultaneously reflect heat and keep moisture out. Mineral wool will also work, but in this case you need to put roofing felt (waterproofing) as the first layer, take care of the vapor barrier, and only then put insulation.

We hope the above information will help you figure out how to insulate a wooden veranda with your own hands and make your home more comfortable even in the dead of winter.

Preface. High-quality insulation of a wooden terrace will maintain indoor comfort and also protect the walls of the house from freezing. In the article we will look at how to independently insulate a veranda with mineral wool, polystyrene foam, penoplex, and how to insulate the floor, ceiling and walls on a wooden veranda.

The veranda is a place for relaxation, tea drinking and friendly gatherings. In summer, the terrace becomes a popular part of the house where the whole family gathers together. However, with the onset of cold weather, you don’t want to be in an uninsulated veranda. The problem of insulating a cold veranda begins to worry home owners with the onset of frost.

But the situation can be corrected - to do this, you should learn how to properly insulate the veranda with your own hands. After the work is completed, you will not have to leave the tradition of relaxing on the terrace until spring. Insulate a cold veranda in country house and continue to enjoy your gatherings. But first, you should consider the question of how best to insulate the veranda.

How to insulate a wooden veranda?

The range of thermal insulation today is quite wide, so the choice of material remains relevant. Meanwhile, there are types of thermal insulation that have proven themselves with the best side when insulating balconies and loggias, insulating rooms with high humidity– steam rooms and dressing rooms.

Leaders in positive feedback and popularity of use - mineral wool, polystyrene foam and penoplex. To improve the effect, you can additionally use a gasket made of foil penofol or isolon - a heat insulator made of foamed polyethylene covered with aluminum foil. The material can also be used alone.

Styrofoam– insulating the veranda with polystyrene foam is the cheapest material to use and is practically not afraid of moisture. But main drawback– this is flammability and increased fire hazard.

Penoplex– superior to polystyrene foam in terms of characteristics. The material can withstand high mechanical loads and is not afraid of moisture, so the insulation of the veranda with penoplex is of better quality.

Minvata– characterized by a high heat transfer resistance. The main disadvantages of the material are moisture absorption and wrinkleability, so high-quality vapor barrier and protection from damage are necessary.

Required tools and materials

– insulation (mineral wool, penoplex, etc.);
– nails, hammer, screws, hacksaw;
– metal scissors, stationery knife;
– tape measure, level, pencil;
– tape, paint, brushes, spatula.

How to insulate a wooden veranda yourself?

If you are thinking about how to insulate a plank veranda, but don’t know where to start, then experts advise starting with the floors. The seams between the boards are foamed, then protected with an antiseptic (like all wooden structures on the terrace), on the lower side (if there is a possibility for this) the floor is sheathed with a vapor barrier or isolon.

How to insulate floors?

As a result, the entire structure of joists and insulation is covered with a vapor barrier and a subfloor made of OSB boards, boards or plywood is laid. Already on this insulated floor you can lay any finishing material. flooring, but before that it is also necessary to insulate the walls and ceiling on the cold veranda.

How to insulate walls?

On the walls, after you have treated the boards with an antiseptic and covered them with a vapor barrier, you need to make a lathing from vertical bars with a cross section of 40 mm, the distance between the bars should be equal to the width of the insulation sheet. The insulation is laid between the beams; if there are gaps, they should be thoroughly foamed.

After laying the insulation, the entire structure is covered with a vapor barrier membrane. If desired, you can make a counter-lattice so that there is a gap between the insulation and the false wall for ventilation. Next, the sheathing or counter-lattice is sheathed wall panels– plasterboard, OSB boards or clapboard - at your discretion.

How to insulate a ceiling?

To begin with, a water barrier is mounted on the ceiling, the seams are glued together with tape, and the surface is sheathed with timber. The distance between the beams also depends on the width of the insulation. If you are insulating the veranda with mineral wool, then the width should be 1-1.5 cm less than the width of the mineral wool slabs so that the insulation fits tightly, without the formation of cracks.

A vapor barrier or foamed polyethylene covered with a metallized film is laid on top of the insulation. Roll material secured with a stapler. Later, it is additionally pressed with a blockhouse or a counter-lattice is made, onto which panels or other ceiling coverings are attached.

How to insulate a summer veranda with your own hands?

If the summer veranda is not an extension to the house, but is located far away, this does not mean that its insulation is impossible. If you have a roof and walls, this can be done. You should start again from the floor.

The floor is covered roll waterproofing roofing felt or glassine, which will serve as a hydro- and vapor barrier. 10-20 cm of insulation is laid on top, then a vapor barrier and finishing coating are laid.

The roof of a summer terrace is insulated like a “pie”, just like insulating the ceiling of a bathhouse with your own hands - waterproofing film on the rafters, slab insulation, vapor barrier and any decorative coating.

The walls of a wooden veranda can also be insulated from the outside. A wonderful opportunity to improve the facade and give the building an updated look is to insulate the veranda outside a private house and cover it with mineral wool siding.

A vapor barrier and sheathing are attached to the outside walls, between which insulation is laid. After covering the structure with a vapor barrier membrane, it is attached finishing cladding, siding or PVC panels.

How to insulate a veranda with your own hands. Video lesson

IN warm weather a veranda or terrace is a natural place for friendly meetings, bachelor parties or family tea parties. Timely insulation of the veranda will allow you to expand such communication throughout the year, keeping indoors warm comfort in spite of the winds and blizzards.

Choosing material for insulation

This procedure can be performed independently; it does not require any special repair skills. In addition, a high-quality insulated veranda is protected from mold, fungi and black spots, which lead to warping of the wood and simply spoil the appearance of the room. Even before the start thermal insulation works it is necessary to make sure that the windows and doors in our extension perform their role well - they do not have gaps or cracks in window glass, fit tightly to the frame, etc. If there are frosty drafts on the veranda, no amount of insulation will help it.

The easiest and cheapest way is to buy sheets of polystyrene foam, but they have a significant thickness (up to 12 cm), thereby significantly narrowing the insulated room. In addition, polystyrene foam is difficult to cut precisely due to its thickness; it will be necessary to provide large stock for cutting losses. Rolled thermal insulation based on mineral wool retains heat better and is much easier to install. You can buy premium materials for thermal insulation like Insulation, Izover or Ursa, with an outer layer of foil or with double-sided metallization. They retain heat best, but the price of such insulation will be more than noticeable.

In conditions severe frosts and extensive premises are used combined option insulation - first roll insulation is mounted on the wall, then sheet foam. The layered structure retains heat well even with large dimensions of the veranda.

Yes, any insulation should be decorated outside! Not only for aesthetic reasons, but also for long-term use. Modern thermal insulation materials they are not resistant to mechanical stress (however, the old ones cannot be called durable either). So you need to stock up on plywood, lining or wall panels for finishing walls and ceiling of an insulated veranda. But with the floor there are options (see below)

Insulating the veranda from the inside - where to start?

From a sound assessment of the total scope of work and necessary expenses. In terms of planning your own time and effort, unfinished repairs are worse than the premises in their original, “pre-repair” state. After measuring the surface of the floor, walls and ceiling, you need to choose your insulation option (foam plastic, thermal insulation rolls, mineral wool, a combination of these materials) and immediately buy them in the required quantity.

In addition, you will need Consumables– bars and slats different sections, nails, moisture-resistant film, glue, polyurethane foam etc. Purchasing everything you need in advance will help you plan your expenses wisely and not be distracted by trips to hardware stores instead of work.

Thermal insulation sequence - moving from bottom to top

Insulation of residential premises begins from the floor. Yes, yes, the cold always comes from below, without “floor” work there is no point in starting on the walls. At a minimum, you need to make sure that the floor retains heat well - perhaps it was planned to replace the veranda living room, and heat-saving functions were incorporated at the stage capital construction. Which happens rarely. So the typical sequence of our repair actions is as follows:

Step 1: Insulate the floor

If the floorboards are good and strong, you can try to remove them, lay our thermal insulation and reassemble the floor - but such insulation of the veranda from the inside with your own hands will require solid carpentry skills.

It is easier to lay the insulating layer directly on the floor, provided that the base is mechanically strong. The cracks in the floor are first covered with epoxy resin or a mixture of sawdust and PVA glue - then, when hardened, even “musical” floorboards will become a monolith. But! Epoxy resin hardens quickly, almost instantly, so you need to work with it confidently and quickly. The mixture of PVA glue with small sawdust hardens for a long time, almost a day. This gives time to calmly process all the cracks, but the floor insulation itself is postponed until the next day.

The base is ready and strong - we lay roll moisture-resistant insulation on the floor and shoot it with a stapler in increments of no more than 10-15 cm (the thicker the insulation, the more often the fasteners). We pierce the corners with nails with wide flat heads, and carefully seal the seams with tape. We lay linoleum or laminate on top. The direction of laying the finishing coating must be perpendicular to the insulating layer - so plan in advance how you will lay the laminate or lay linoleum over the new thermal insulation.

If desired, a “double floor” system is equipped - logs are laid on the insulation and a full covering is assembled from new floorboards or solid board. But such repairs are quite expensive and significantly reduce the height of the room. In addition, you will have to redo the doorways and the doors themselves to the veranda.

Step 2: Insulate the walls

If the walls are made of boards, then they are carefully removed and the board veranda is insulated along the “wrong side” of the facade. Then the old boards can be put in place, puttied and wallpaper pasted, MDF panels, wall plastic, etc. mounted, depending on design preferences and the renovation budget. Often the kitchen is taken out onto the insulated veranda - then it is used in wall decoration. tile or PVC panels for the kitchen.

On brick or concrete walls a sheathing of wooden slats is nailed (targeted). Bars with a cross section from 25x25 to 40x40 mm are selected. The foam can be tightly inserted into the resulting openings (then they are made wide and deep, according to its dimensions) and glued along the end. In general, when working with foam plastic it is easier to assemble mounting lathing, based on the size of its sheets, rather than vice versa - sawing hard material on an already installed grid.

Thermal insulation in rolls is stitched (nailed) to the slats, the seams are taped. If it is used without foam, then the mounting slats are selected thin, along the length of the fastening nails, in order to preserve the space of the veranda. If necessary, you can combine the installation of foam plastic and rolled thermal insulation on the same sheathing.

Step 3: Insulate the ceiling

The procedure will require waterproofing works, any ceiling is exposed to precipitation. Even if the roof is good, there is no escape from moisture condensation, accidental leaks, etc. First, the ceiling lining is removed and a special hydraulic barrier is installed. roofing film with fine perforations, the seams of the film are carefully taped with metal-coated tape. Further work is similar wall installation insulation material, with the exception of safety measures. When insulating the ceiling, it is necessary to use safety glasses, as there is a danger of eye injury when attaching insulation with nails, shedding small chips, etc.

We insulate a terrace or summer veranda

It is quite possible to make a living space without walls at all - that is, to carry out insulation of the terrace with your own hands, including if it is located in the form of a separate building. The main thing is to have a waterproof roof over your head. The typical sequence of actions is as follows:

• Along the perimeter of the terrace you need to install an improvised plinth - a fence made of bricks or cinder blocks with a height of at least 20 cm.
• The floor is prepared according to the procedure described above and covered with insulation - carefully gluing the seams with tape and fastening them to the base with nails, everything is as it should be. Required thickness of thermal insulating material for open verandas– at least 6 cm;
• A moisture-proofing film is laid on top, which acts as a water barrier - against accidental splashes of rain and snow drifts;
• The finishing floor covering is made of linoleum, laminate, or solid board;
• The ceiling is sheathed in exactly the same way as when working in closed verandas, only waterproofing is laid in two layers - for reliability;
• Double-glazed windows are installed on the entire wall - you get a new terrace with windows in french style. You can, of course, board up the openings with ordinary film - but there will be no time for aesthetics, no time for comfort.

Expanding the warm space of your home yourself is easier than it seems. This work is quite doable alone, all materials are reasonably priced, availability is required simple tools and basic repair skills. You can try to assemble thermal insulation on a separate section of the floor or wall on the same summer veranda- to understand how much you can handle this matter. Additional tens square meters living space are worthy of several days of summer effort - because their results are noticeable all year round.
