Insulating a veranda from the inside with your own hands for winter living in a wooden house - an overview of materials and step-by-step diagrams. We insulate a veranda for winter living with our own hands How to insulate a veranda for winter living outside

In order to insulate an extension to your house, you will need good thermal insulation material. The optimal solution for internal and external insulation – mineral wool slabs. They are excellent for insulating walls and floorboards, have good thermal conductivity, are moisture resistant, durable and inexpensive. For interior work you need insulation with a thickness of 50-70 mm.

Insulation of walls and ceilings of an extension from the inside

List of required materials:

Waterproofing film to protect insulation from moisture.
Fasteners and metal profiles for frame construction and plasterboard cladding.
Wooden slats with a section of 5 x 2 cm.
Plasterboard sheets for final wall cladding with a thickness of 9.5 to 12 mm.
Putty for processing seams between plasterboard sheets.

Warming stages:

Creation of lathing for attaching thermal insulation. On the surfaces to be insulated, we fill prepared slats or boards with a distance slightly less than the width of the insulating panels.
Installation of insulation. Place between the bars mineral wool. So are the walls.
Waterproofing. We cover the entire insulated surface with a vapor barrier membrane, overlapping the edges. We fix the film with staples on the sheathing bars.
Frame for plasterboard sheets. We fasten vertical and horizontal metal profiles, creating a frame for the final cladding.
GKL covering. We install drywall on the walls and ceiling.

Note. In principle, instead of drywall, you can use other material for sheathing. It could be wooden lining, plywood, OSB or GVL. Choose what suits you best in terms of external and internal characteristics.
Processing of joints. Using putty, we cover the joints between the plates and clean them.
Cosmetic finishing. The finished surface can be painted, covered with wallpaper, tiled or any other finishing materials.

Features of wall insulation made of certain materials

Walls made of foam concrete blocks are warm due to the huge number of air bubbles contained in the foam concrete, but additional insulation work cannot be done, otherwise heating costs will be too high. Insulating the outside is much more expensive because it requires cladding. Proper insulation walls from the inside requires good vapor barrier and ventilation of the insulating layer on both sides.

It is recommended to avoid highly absorbent, fibrous, moisture-permeable insulation materials. These measures are necessary to reduce humidity in the extension and prevent freezing of the walls. When installing insulation, it should be taken into account that cold penetrates into the room through the joints.

Mineral wool is not suitable for foam concrete blocks; expanded polystyrene sheets require additional joining. The best insulation such walls - spraying polyurethane foam. It prevents the formation of condensation. For education required thickness insulation layer should be used wooden sheathing. Metallic profile creates cold bridges. A waterproofing layer is secured on top of the foam with slats, and then drywall is attached. The dew point is located at the point of contact between the polyurethane foam and the foam block extension or inside the polyurethane.

The disadvantages of spraying polyurethane are the high price and the need to attract special equipment and trained specialists.

Insulating the walls of a frame extension from the outside

We do external insulation of an extension to a frame house according to the same principle as internal insulation. First, a vertical frame made of wooden beams. The distance between the boards should be about 50 cm, slightly less than the width of the insulation. Mineral wool blocks are tightly inserted between the beams, which are covered with a layer of waterproofing. The film is strengthened with staples around the perimeter of the frame. At the final finishing stage the surface is covered with siding.

Outside or inside, which is more effective?

Advantages of internal insulation

insulate the ceiling, floor, walls in one step;
work can be performed in any weather conditions;
simplicity - insulated surfaces are available throughout the entire height.

Disadvantages of internal insulation

The freezing point during internal insulation shifts into the wall, which contributes to its faster destruction. In addition, if the extension room already has finishing, decorative coating will have to be dismantled.

Advantages of external insulation

displacement of the freezing point in the insulation, due to which the rate of destruction of walls decreases;
the internal living space of the extension is preserved;
no waste from construction work indoors;
the possibility of using the extension during work, the way of life is preserved;
additional protection wooden walls from getting wet.

Disadvantage of external insulation

Insulation of concrete floor

List of materials you will need:

insulation – mineral wool boards;
vapor barrier;
scotch;
damper tape;
reinforcing mesh;
screed solution.

Stages of insulation

On concrete base a layer of vapor barrier film is applied. The insulation joints must be carefully taped to ensure the overall tightness of the layer.
On top waterproofing material Insulation boards are laid. It is important that the blocks fit tightly to each other, there are no gaps or cracks left.
The entire perimeter of the room is covered with damper tape. This is necessary to compensate in case of expansion of the screed.
Another layer of vapor barrier and then a reinforcing mesh is applied on top of the mineral wool insulation.
The screed is poured. Its thickness should be at least 3 cm.
After the surface has completely dried, any topcoat is applied.

Floor insulation on beams

List of materials - what you will need:

wooden boards, logs;
insulation;
vapor barrier coating;
clay mortar;
plywood.

Stages of work

Attach smaller transverse joists to the floor beams. Lay the boards on the joists with rough, continuous flooring to prevent heat from escaping. Coat the coating with a thick clay solution, wait until it dries and apply a layer of vapor barrier on top. Place insulation boards between the joists and cover it with another layer of vapor barrier. Cover the surface with boards or plywood on top. Lay a decorative coating to your liking on the resulting wooden floor.

Roof insulation

To properly insulate the roof of an extension to a house, the following principle should be observed: all layers of the insulation cake must provide moisture insulation on the outside and vapor permeability on the inside. For thermal insulation of roofs, polystyrene foam, penoplex, and polyurethane foam are used, but mineral wool and other fiber insulation in combination with membrane films for removing water vapor are best suited.

Types of insulation - features, characteristics

Mineral wool. It has low thermal conductivity, is fireproof, durable, flexible, temperature resistant and chemical substances. In addition, mineral wool insulation provides good sound insulation. Cons: a frame is required for installation, after some time of operation it becomes compacted and loses its thermal insulation properties.
Polyurethane foam is produced in three types: flexible, dense, sprayed. Polyurethane foam is easy to install, lightweight, and resistant to biological and chemical environments. Disadvantages - expensive price, quickly ages from ultraviolet radiation, deforms from mechanical stress, has a low vapor permeability indicator, which is why it accumulates moisture, which has a detrimental effect on the walls of the house.
Penofol is environmentally friendly, flexible, and easy to install. The material has low vapor permeability and high combustion resistance. Cons: thin, overly soft. Expanded polystyrene has low weight, sufficient rigidity, and is easy to install and cut. This is a very durable, wear-resistant material. Cons – can’t stand it high temperatures from 100 degrees, has low soundproofing qualities.
Basalt wool is a fibrous material whose properties and performance characteristics are identical to mineral wool. Disadvantages - during operation it becomes compacted, which increases thermal conductivity.
Polystyrene foam is light and hard, does not lose its performance properties even after long-term use, and can be mounted using both frameless and frame methods. Insulation with low vapor permeability and hygroscopicity. Cons: flammable, loved by rodents.
Moss, flax, tow - used for insulation without disturbing the appearance of the building. Such materials are certainly environmentally friendly. Disadvantages: they are specific, difficult to install, and are of interest to animals and birds that build their nests from them.

When insulating an extension with your own hands, it is always better to start with the walls. How to insulate an extension, whether it will be external or internal insulation, depends on the size, characteristics of the room and the personal tastes and preferences of the homeowners. The insulation process itself does not take much time, and the cost of materials for such work will not hit the budget.

Almost every house has an extension in the form of a veranda, where you can spend a pleasant summer evening.

Usually it is built of wood, so it becomes unsuitable for the winter season. But there is a way out - insulating the veranda from the inside with your own hands.

Veranda layout.

The terrace is an open area, so, as a rule, it is not insulated.

To insulate the veranda you need to stock up the following materials and tools:

insulation. You can use penofol, mineral wool or some other;
polystyrene foam. The thickness of the foam sheets depends on the natural conditions of the area, as well as on the dimensions of the veranda;
bars measuring 50x50 mm;
polyethylene or foil;
polyurethane foam;
construction tape and paint;
The tools you will need are scissors, a spatula, a knife, nails, a hammer, screws, a tape measure and brushes.

Warming the veranda floor

It is better to start insulating the veranda from the floor.

Floor boards in wooden houses are usually attached to joists laid on the ground. To insulate the floor, you must first free it from the boards. Next, between the lags you need to lay wooden blocks 50x50 mm in size and fasten them with screws. Insulation is laid between the bars.

Foam or mineral wool materials are better suited as insulation.

It is important to completely fill the space tightly with insulation. Foam sheets can be easily adjusted to any size of joists, as it is easy to cut with a knife. To protect mineral wool from excess moisture, it is necessary to insulate it using polyethylene or foil. IN empty seats they launch a special polyurethane foam.

The height of the insulation should be slightly below the floor level to ensure ventilation, which will protect the floor elements from rotting and getting wet. At the end, a polyethylene film is stretched over the insulation, fixed at the edges with metallized tape. Now the floor is being laid.

Insulation of veranda walls and ceilings

Option to insulate walls from the inside.

If the veranda is located inside the house, then only the external walls, the walls in contact with interior rooms no need to insulate.

Before insulating the walls from the inside, they must be covered with waterproof material. Polyethylene or foil is glued in horizontal stripes.

We insulate the veranda for winter living with our own hands

The resulting joints are covered with tape to avoid any air voids. In accordance with the dimensions of the insulation boards, bars are placed on the wall.

The space between the bars is filled with insulation in the form of mineral wool, the foam is glued special glue to Wall. The easiest way to insulate is with polyurethane foam, liquid foam.

He has good protection from the cold and long term service, fills all voids well, forming an even coating. Insulation boards must be wrapped in polyethylene foam. When using heat-reflecting material, it should be positioned with the metal surface inward. Having insulated the walls inside, you can close the structure finishing material, clapboard or something similar.

In order for the room to be truly warm, it is necessary to insulate the ceiling.

If warm air, going up, will not meet a good barrier, he will leave the room. When insulating the ceiling, the heat that comes in will be retained. The ceiling is insulated similarly to the walls. The insulation must be insulated from moisture, then wooden strips must be filled with which the insulation is secured. To fill the voids, special mounting foam is used, and to finish the ceiling, lining or other finishing material is used.

If the veranda consists mainly of window frames, then it is better to use triple frames, since a lot of heat is lost through the windows.

To provide fire safety Non-flammable materials, for example, mineral wool, should be used as insulation. For greater effect, you can also insulate external walls. This insulation can protect the walls from precipitation, thereby increasing their service life.

Thus, any homeowner can properly insulate a veranda with their own hands; the main thing is to prepare all the materials in advance and decide on the scope of work.

If you want to expand the useful area in a country house and use it in winter time, it’s time to find out how to insulate a cold veranda. This procedure will also not be superfluous for creating a more favorable microclimate for the building in this room. Otherwise, it will freeze, become damp, and as a result become unusable. With a competent approach to the matter, it is better to insulate the verandah during the construction stage. But this is not always possible, either for economic or functional reasons.

Each structural element (floor, ceiling and walls) has its own insulation characteristics.

When is the best time to insulate a veranda?

It is worth immediately noting that having correctly solved the problem of how to insulate a veranda for winter accommodation, and by creating a kind of thermos out of it, you can significantly reduce heating costs.

This factor will also be relevant for baths. There are two fundamentally different options How to insulate a cold veranda for living space: outside and inside. If possible, it is better to use the outdoor option.

It is better to hold the event in the warm season, since there are materials that can only be used at positive air temperatures. That is, when deciding what and how to insulate the veranda of a house from the outside, you need to focus on the season and weather.

If outside the windows negative temperatures, then it’s worth considering the option of how to properly insulate the veranda from the inside. The event can be held during the construction stage of your country house. But you can solve the problem of how to insulate the veranda with your own hands already during your stay.

The vast majority of additional rooms in country houses are built from wood. Therefore, it is worth noting that there is no fundamental difference in how to insulate a veranda made of boards or a wooden veranda from the inside.

In approximately the same way, adjusted for building materials, warm rooms are arranged in buildings made of concrete, gas blocks, bricks, etc.

We insulate the veranda in stages

When insulating the veranda, you should adhere to the following order:

roof;
walls;
ceiling;
window;
doors.

How to insulate a veranda roof

To solve the problem as correctly as possible, how to insulate a veranda in wooden house, you should first inspect the roof structure.

If it is a continuation of the main roof of the house, then there is no need to touch it. If this element is a simple ceiling, then it is necessary to solve the problem of how to insulate the roof of the veranda.

First, the structure is thoroughly sealed.
Next, we lay a thick layer of insulation material.
The best option for carrying out the work would be foil insulation. It will allow you to carry out the procedure quickly and with little effort.
Don't forget about the vapor barrier so that the roof doesn't get damp.

When insulating this element of the building, you should take care of the reliability of the structure, since it is difficult to access.

Only after working on the roof can you move on to insulating the veranda as a whole.

How to insulate veranda walls?

To correctly solve the problem of how to insulate a summer veranda, you need to start with the walls.

This is advisable, since these structural elements will require less effort from the master. When choosing a technology for how to insulate the walls of a veranda, it is better to focus on the frame method. Practice shows that the insulating structure is more reliable than when using the method of gluing the material. Mineral wool, polystyrene foam, polystyrene foam or polyurethane foam can be used as insulation material. The main goal in the question of how to insulate the walls of the veranda from the inside or outside is to stop the access of cold to the room.

The frame method of insulation involves the use of timber, its thickness should be equal to the thickness of the insulation.
Before insulating a veranda in a private house, it is better to treat the wood with impregnation to prevent the appearance of mold and fungi. A cellular structure is assembled from timber using self-tapping screws.

The cell dimensions must be equal to the dimensions of the material slabs.
Now you can begin installing the insulation. The slabs are laid in cells against the frame, without cracks or gaps.
After installing the insulation material, a vapor barrier must be laid over the structure with an overlap of 10 cm. It is secured using a stapler and staples. It is better to seal the joints with tape. A vapor barrier will protect the insulation from moisture.
This is very important point in the question of how to properly insulate the veranda.
Then you can sheathe the structure with any finishing material: lining, plasterboard, MDF boards or PVC panels. Once the walls are ready, you can move on to working on the ceiling.

How to insulate a veranda ceiling?

Everyone knows that warm air rises and forms an air cushion near the ceiling.

But its presence does not prevent cold air from entering the room through cracks and gaps. Therefore, it is better to solve the problem of how to insulate the ceiling on the veranda along with other elements of the building. Many people think that these works are quite complicated, but this is not so.

The main thing is to initially choose the right technology: from the outside or from the inside.

The insulation material will also depend on the chosen method:

Exterior works.
If you decide to insulate the ceiling from the outside - along the floor of the attic, then it is better to choose frame technology and insulation in slabs, for example, polystyrene foam. Don’t forget to lay a vapor barrier on top of the structure. Attic insulation More often used during the construction of a house, but it can be implemented later.

The advantage of insulating the ceiling from the outside is that it does not reduce the volume of internal space.
Interior work. But with the task of how to insulate the ceiling on the veranda from the inside, using frame technology, difficulties arise. If the beams are attached to the surface with screws and do not interfere with the continuation of work, then the insulation in the slabs will simply fall out of the cells under the weight of its own weight. It is recommended to immediately secure it with a vapor barrier. Immediately upon completion of installation, the cladding material should be installed. You can also install an already installed insulation structure.
The work will be fundamentally simplified if foil insulation is used to insulate the room. Now you can move on to insulating the lower structural element - the floor.

How to insulate the floor of a veranda?

Before you independently insulate a wooden floor on a veranda, it is worth opening up the floor covering and examining the structure to see if there are logs in it and whether they can be used.

If the answer is positive, the procedure can be carried out using insulation material in slabs.

Otherwise, you will have to lay the joists on top of the existing surface.
Then fill the cells with insulating material, similar to working with walls.
And complete the work by laying a vapor barrier.
After laying the thermal insulation structure, a solid base can be laid for flooring, for example, OSB boards.
It is better to seal all seams with sealants.

If you want to make your task easier, you should ask yourself how to properly insulate a wooden veranda floor with foil insulation.

This is a technologically advanced material that allows you to work with structures of any geometric shape. Foil insulation can be used to insulate buildings made of any materials.

How to insulate windows

The main heat loss in any room occurs through doors and windows.

Therefore, when solving the problem of how to insulate a veranda with your own hands using polystyrene foam or other material, special attention should be paid to these openings:

The best insulation option would be to install PVC windows. You can install single-glazed windows, but this will significantly reduce the temperature balance in the room. The larger the volume of glazing, the lower the heat saving indicators.

Therefore, it is better not to save money, but to immediately install double or triple glazed windows.
The tightness of the junction of these elements should be carefully monitored. Double-glazed windows, as a rule, are foamed; in some cases, strip thermal insulation can be installed.
But PVC glazing- a very expensive undertaking. If you want to save money, you can add a second one to the existing frame. This is what our ancestors did before the onset of winter. In this case, the cracks are filled with foam rubber or other soft material, and a special tape is glued on top.

How to insulate doors

In this case the best option will be the installation of a modern front door.

How to insulate a veranda from the inside and outside during the winter? We insulate a cold veranda

It was originally designed to retain heat in the room:

Companies producing and installing metal entrance doors, in their catalog, as a rule, have several models intended for installation in a private home.
If you want to avoid additional expenses, you need to insulate the structure yourself. For example, it can be covered with felt or an old stuffed blanket.
It is better to cover the structure, both from the outside and from the inside.
In order for the door to look aesthetically pleasing, a leather substitute, matting and other materials are mounted on top of the insulation.
Self-adhesive rubber seals must be installed around the perimeter of the door.
If you want to radically solve the problem of how to insulate a summer veranda, install a second internal one, this will create an additional air gap.
After completing the work, you can begin finishing the room and continue to use it in the winter.

Let's summarize

The veranda requires constant maintenance, as does the house itself.

By insulating this room, you will not only expand the usable space for use in the cold season, but also save yourself from regularly updating the finish and treating structural elements with protective impregnations. It is better to carry out insulation already at the construction stage. Take advantage of our unique offer and you will receive a functional and comfortable country home at a competitive price.

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 the appearance of mold, fungi and black spots, which lead to warping of the wood and simply spoil appearance premises. Even before the start thermal insulation works we need to make sure that the windows and doors in our extension perform their role well - they have no gaps, cracks in the 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, foam plastic is difficult to cut precisely due to its thickness; you will need to provide a large margin for losses during cutting. 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 of severe frosts and large rooms, a combined insulation option is used - first roll insulation is mounted on the wall, then sheet foam is installed. 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, clapboard or wall panels for finishing the 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?

With a sound assessment of the total scope of work and the required costs. 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 of various 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:

The sequence of thermal insulation of the veranda - step-by-step diagram

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. Flooring direction finishing coating must be perpendicular to the insulating layer - so plan in advance how you will lay the laminate or lay linoleum on the new thermal insulation.

If desired, a “double floor” system is equipped - logs are laid on top of the insulation and a full covering is assembled from new floorboards or solid boards. 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 the sheathing is nailed (targeted) from wooden slats. 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 polystyrene foam, it is easier to assemble the mounting lathing based on the size of its sheets 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 water barrier is installed - a special roofing film with fine perforations; the seams of the film are carefully taped with metal-coated tape. Further work is similar to wall installation of insulating 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 insulation 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 the 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.

Specialization: master of internal and exterior decoration(plaster, putty, tiles, drywall, lining, laminate and so on). In addition, plumbing, heating, electrical, conventional cladding and balcony extensions. That is, renovations in an apartment or house were done on a turnkey basis with all necessary types works

If you have a house or cottage outside the city, then you probably had to think about how to insulate the veranda for winter living. This is far from an idle question - and even if you don’t sleep there, warm room in front of the main building significantly saves energy costs for heating.

Today I want to tell you how to make insulation in a private house with minimal costs, taking two paths separately, or combining them with each other.

Two directions in insulation

Let me make a reservation that a veranda is usually called an open or glazed room attached or built into the main building. It is noteworthy that we are not talking about heating here, therefore, it is possible to insulate both a plank and a stone extension only in other ways.

Option 1: double-glazed windows

Since we are talking about insulating a veranda in a wooden house (brick, stone), then, of course, this means not an open, but a glazed room:

main source cold the temperature in this case is the windows, of which there are, of course, a lot, but this, alas, is an integral part of such a room;
therefore, we can reason like this - if we cannot reduce the number of windows in this room, which are the main source of cold, which means that it is necessary to somehow reduce the conductivity of this bridge;
the only thing we can do in this case is to install frames (plastic, aluminum, wood) with double-glazed windows (single, double, triple);
Of course, with such glazing the price of windows will increase significantly, but you get high-quality products that will in no way make the interior or exterior of the room worse, but will even improve it;

of course, the frames themselves cannot be neglected, especially if they are made of aluminum, which is an excellent thermal conductor;
if the stained glass windows are made from this particular material, then make sure that it is “warm” aluminum, for example, as in the top schematic image.

No matter how you increase the thermal insulation capacity of the ceiling, walls and floor with your own hands, all your efforts will come to naught with single stained glass windows. It will be the same as if you put on a hat and boots, but at the same time remained in only your underwear in the cold.

Option 2: floor, ceiling, walls

One of the most powerful sources of cold in a room can be a floor that lacks hydro- and thermal insulation, especially if the building is located in the northern regions of our country. Let's start with waterproofing.

Any moist substance is an excellent conductor of cold, not to mention problems such as dampness and rotting. Therefore, if the shut-off waterproofing was not laid during construction, then it must be installed now.

This can be roofing felt or thick polyethylene film (I am not mentioning vapor-permeable film - it is too expensive, and besides, you can completely do without it).

And now - about materials for insulation. For example, mineral wool, polystyrene foam, extruded polystyrene foam and, of course, expanded clay - the cheapest and most reliable component of country construction.

I would also like to say about the sand pillow, if you add it, of course. Waterproofing should be laid not on it, but under it - this way we will minimize the amount of moisture from below.

The ceiling can be insulated both from the inside and outside - it all depends on what kind of roof is on your veranda and, of course, on your desire. Regarding the material here, the same can be said as for the floor, but it all depends on its location - from below, of course, it is much more convenient to use foam plastic or mineral wool.

But, if you consider that verandas generally have a pitched roof, there is no attic there, therefore, in 99% of cases, the insulation has to be hemmed from below, that is, internal installation must be done.

In order to do internal insulation, you will have to mount any of suspended ceilings, for example, like the one in the photo above, for . But insulating the veranda from the inside with your own hands in this way may not always work out for the most trivial reason - low ceilings, which, well, it’s simply impossible to lower another 5-6 cm.

In this case, there is only one thing left - to install some kind of insulation under the roofing material, only with good waterproofing. And this will be more difficult, since you will have to dismantle and then reinstall the roof.

Well, finally, let's look at how to insulate a cold veranda for living space inside or outside along the walls. Let me note that there is nothing new to say here. In such cases, as a rule, mineral (preferably basalt) wool or polystyrene foam is used.

The thickness of the material directly depends on the need, that is, on the thickness and climate of the region. There's one here small nuance- if the insulation is installed outside, it will bring more benefits than from the inside, and you can see its effectiveness in the diagram above.

Another point - by insulating the room from the outside with polystyrene foam, you get the possibility of “wet finishing”. That is, you can tile the veranda decorative plaster directly on the foam (of course, with a reinforcing plaster mesh).

Conclusion

Insulating the veranda either from boards from the inside or from any other materials from the outside is beneficial only if there are no drafts and there are windows with bags. Do you have any questions or suggestions? Write about it in the comments.

Do-it-yourself insulation of the veranda from the inside is quite in demand in the harsh climate of Russia. Owners often want to make an additional room warm in their country house or in their home. Otherwise, the unheated veranda will freeze and become damp, and because of this, the finish will quickly begin to deteriorate.

A competent approach to the construction of a veranda requires its insulation even at the start of construction. But if the house has been purchased, insulating the terrace with your own hands should be done if necessary.

Insulation of the veranda is carried out in any season of the year.

The building can be finished:

Outside. It is better to carry out such work only in good weather: when it is easier to work and the materials used will not be damaged.
From the inside. This method is relevant in cold weather and even cold weather. In this case, you can immediately:

insulate the veranda;
prepare a good base for interior finishing.

After the room becomes warm, you can gather here in winter with the whole family and friends over a cup of warm coffee.

What material is chosen for insulation?

The best option for finishing the veranda may be:

Minvata.
Styrofoam. But if it unexpectedly comes into contact with fire, quite dangerous carcinogens will be released, which should not be ignored. However, the relatively low price makes the material available for insulating such a room. Polystyrene foam is a budget option.
As additional material You can use a foam pad. Its metallized layer will be able to reflect cool air from the street, and heat will be retained inside the veranda. This material is a high-tech, heat-insulating product consisting of a layer made of foamed polyethylene and high-quality aluminum foil covering it. This “reflected” layer can also be used as a separate independent thermal insulation. But for maximum effect To preserve heat, it is necessary to combine penophenol with other types of insulation.
Effective options for insulating a building with your own hands are polyurethane foam, basalt wool, and resole foam.. These materials do not burn.

Details about insulation

How to insulate a foundation

Tip: For the veranda you should choose a foundation of the same type as the main building - concrete slabs, monolithic concrete or strip base.

The base material does not at all block the cold coming from the ground in winter, so the foundation can freeze through. Through it, heat loss reaches up to 20%. There are several ways to insulate a cold veranda, namely its base.

It could be:

Filling the internal space with earth or expanded clay.

Such options are used only when constructing a veranda, when foundation work is being carried out. For this:

the formwork is removed;
the entire internal area is covered with expanded clay or earth, which is very cheap, especially when there is excess soil left after construction. But at the same time, the quality of its heat conservation is low.

The expanded clay layer does not allow moisture and frost to pass through concrete slab. Expanded clay has greater thermal insulation, but it will need to be purchased, which will increase costs.

Tip: To insulate the base, you should make a double layer: the first layer is filled with soil, and then expanded clay stones are laid.

Pasting with polystyrene foam.

If there is heaving soil, it is necessary to perform external insulation of the foundation walls with polystyrene foam. This is due to the deformation of the base, which occurs due to the expansion of the soil during periodic thawing and freezing.

In this case, the insulation layer plays the role of an insulator, saving the base from direct contact with the ground and blocking the frost. The entire outside surface concrete, including the base.

Tip: Before polystyrene foam is glued, the entire foundation must be covered with mastic for waterproofing, as shown in the photo.

The work order is as follows:

Polystyrene is laid on the outside of the foundation, which is dug out to the very foundation.
The first row is mounted on a gravel bed.
The base is coated thoroughly with bitumen-polymer mastic for a waterproofing layer.
After drying, polystyrene foam boards are glued on.
The adhesive composition chosen is polyurethane, which is applied in dots or smeared on the entire sheet.
The joints between the plates are glued, which will make it possible to avoid cold bridges and rid the base of cracks into which moisture can penetrate.

Most new way external insulation – polyurethane foam spraying. It consists of liquid components and is sprayed onto the foundation using special equipment. After complete hardening, the coating acquires density, becomes monolithic and quite durable.

According to its characteristics, the composition is not inferior to extruded polystyrene foam, although the cost of the work is much higher. There are no joints, which improves the quality of thermal insulation.

How to insulate floors

Apart from the foundation, the floors are closest to the ground. Their insulation must be carried out to avoid the appearance of black spots of dampness in the corners.

The floors on verandas are usually poured with concrete. When planning a heating device using a “warm floor” system, it should be done on initial stage pouring floors.

In this case it is better to choose electrical system, switched on as needed. At low enough temperatures, the water floor may freeze and freeze only in the spring, or the coating will need to be dismantled to warm up the existing pipes.

If there are old tiles on the veranda, the insulation can be laid directly on it.

The procedure for insulating floors in an unheated room is as follows:

The entire underground area is covered with crushed stone.
Sand is poured on top and compacted thoroughly.
Rods for reinforcement are laid out or a mesh is placed, which will protect the concrete from cracks.
Done concrete screed five centimeters thick.
After the pour has hardened, a waterproofing layer is created. The easiest way is to make a screed coated with water-repellent mastic. However, a less expensive option is to lay roofing felt sheets and fasten them together bitumen mastic or roll them, pre-heating them with a burner.
Logs impregnated with an antiseptic are installed on top of the waterproofing, and insulation is placed between them, which can be mineral wool foiled on one side. The foil prevents infrared radiation from leaving the room, with which a lot of heat evaporates. The insulation rolls are laid after all the joists are installed.
Insulation can also be done with polystyrene foam. In this case, the joints between the plates are blown with foam, and the excess material is cut off after drying.
Planks or decking are laid.

Tip: Everyone wooden parts must be carefully treated with antiseptics to protect them from rotting, and then painted with a protective composition.

To avoid dampness, which the tree is very afraid of, organize good ventilation. To do this, ventilation vents are made in the foundation, located below the floor level.
The insulation is placed with the foil facing up, which prevents heat from being reflected back onto the veranda.
Decking does not require ventilation in the underground - it does not deteriorate due to temperature changes and the appearance of dampness. Decking is a board, but previously treated with compounds at the factory. Larch is used to make it; it is not afraid of frost and moisture. This material is usually lined open terraces. But, the cost of such floor covering is quite high.

How to insulate veranda walls

The walls of such a room are usually insulated from the inside, and from the outside only to give the veranda a presentable appearance.

When insulating wooden walls, you must:

Seal all cracks in the building.
Place a vertical sheathing on the tree using beams with element spacing of up to 0.5 meters.

Tip: When stuffing slats, you should measure the width of the insulation, and then fill them exactly to its dimensions. In this case, all the slabs will fit tightly to the sheathing.

Mineral wool is installed between the slats, which is secured with dowel umbrellas.
The waterproofing film is fixed on top with a stapler.
The surface is finished with clapboard, siding or other finishing material (see).

Insulating a veranda with your own hands from block walls:

They are glued to the walls with a special adhesive composition polystyrene foam boards, they are additionally strengthened with dowel umbrellas.
The same glue is applied on top of the slabs and a reinforcing mesh is attached to them.
After final drying, the walls are covered with decorative plaster.
Surfaces are painted.

Before insulating the veranda from the inside, all cracks must be carefully caulked.

The procedure for insulating a terrace with your own hands is as follows:

The sheathing is being filled.
The waterproofing film is fixed with a stapler; it will protect the insulation from moisture from the street.
Mounted metal carcass, onto which the drywall will then be attached.
The frame is filled with mineral wool.
The laid insulation is covered with a vapor barrier film.
Drywall is being installed.
The finishing coat is carefully applied.

Tip: The distance between the metal profile elements on the frame should be equal to the width of the insulation sheets.

How to insulate a veranda from the inside with polystyrene foam can be seen in detail in the video in this article. Each owner of his home decides for himself how to insulate the veranda from the inside. The main thing is that it is warm and cozy here.

How to check the tightness of windows and doors installation

If we insulate the veranda with our own hands, we must ensure that there is no heat loss from windows and doors. When installed on the veranda of old wooden windows, you will need to carefully check their tightness.

For this:

Attention is drawn to the quality of installation of the beads, which just need to be pulled.
If they crack or begin to wobble, all glass must be removed, the grooves cleaned, and then their surfaces coated with silicone sealant.
The glass is inserted back and sealant is applied along the edge.
They are pressed with new glazing beads.

At the joints of the window opening and the frame, you need to go over it with a regular metal ruler. Where it passes freely, there are cracks that must be sealed with polyurethane foam. The front door is checked in the same way.

How to insulate a veranda ceiling

A significant part of the heat can escape through the ceiling, which requires insulation. The best option may be to lay foil-coated foam polymer between the beams, which will simultaneously retain heat and keep moisture out.

You can also use mineral wool, but in this case the first layer will be roofing felt and serve as a vapor barrier, and insulation boards are laid on it.

A few nuances when insulating a veranda

To have an insulated veranda to a house with large window frames was as warm as possible, it is recommended to install a triple frame structure.

Besides:

Before insulating the veranda, you need to take care of the fire safety of the building. For this purpose, non-combustible materials must be selected.
In the event of a fire, a veranda that is not protected by fire-resistant materials, even with a small amount of fire, can flare up and catch fire in a very short time.

Insulating the veranda yourself will not be difficult; the main thing is to determine in advance what to insulate and with what.
