The issue of thermal insulation of the veranda using becomes relevant when there is a desire to use this room all year round. The verandas are usually unheated, as a result of which the temperature in them can drop below zero in winter.

If you want to ensure a comfortable air temperature inside the veranda even in the coldest season, you need to take care of the quality insulation of the extension.

With complex thermal insulation using proven materials, and installing an elementary heating device: a small solid fuel stove or a good electric radiator, it is possible to ensure a constant temperature in the veranda at + 18 + 19 degrees.

1 Carrying out work from the inside

It’s worth mentioning right away that since the construction of a veranda, as a rule, is a budget project, as a result of which it is being built from inexpensive materials- wood, cinder blocks, or gas silicate blocks, it will be necessary to insulate the veranda comprehensively.

You can, of course, insulate only the walls and even make or ceiling, but you will not get the desired effect from such thermal insulation.

To make a full-fledged year-round living space out of the veranda, it is necessary to insulate both the surface of the walls from the outside and the ceiling, walls and floor from the inside of the building.

1.1 What is the best way to insulate?

If savings are at the head of the insulation project, then ordinary foam can be used as a heat-insulating material. This material has good thermal conductivity, and is inexpensive.

It is also easy to work with foam plastic, even one person can handle it without problems, so if you plan to do everything yourself, foam plastic is a good option from inexpensive heaters.

The thermal conductivity of the foam is approximately 0.04 W / mK per , which, of course, is less than that of mineral wool, or extruded polystyrene foam, but also quite good, given the cost of this material.

For insulation of walls, ceiling and floor, you can take foam plastic 5 centimeters thick - in most cases it will be enough.

Expanded polystyrene wins not only in terms of thermal insulation properties. An important fact is that this material has minimal vapor permeability and hydrophobicity, as a result of which condensation will not form on its surface, which is the main enemy of most heaters.

The advantages of expanded polystyrene also include ease of installation - this insulation is made in the form of plates with dimensions of 100 * 160 cm, for the installation of which in most cases only an adhesive solution is sufficient.

2.1 Do-it-yourself veranda insulation technology (video)

It is difficult to imagine a country cottage or cottage without a veranda. Basically, such a building is used only in the warm season. But often, in order to increase the usable area and operate the premises in winter, they perform the insulation of the veranda,. About how to implement it correctly and with minimal cost, we will tell in this article.

Warming methods

How to make a veranda suitable for winter residence? It is desirable to think over the possibilities of thermal insulation at the beginning of construction, since after completion of work, labor costs and financial investments increase several times.

Insulation of the veranda involves the installation of insulation on the floor, walls, ceiling. However, due to the influence of the atmospheric environment, not all types of materials are suitable for solving this problem.

The best option serve as roll and plate heaters based on natural minerals. They are quite air and vapor permeable, which contributes to the free removal of moisture and protects the wood from rotting and damage.

Less preferred for the veranda are artificial polyurethane foam insulation, which have low vapor permeability. These materials are more often used for external insulation, the plates are mounted on a pre-installed timber frame.

Starting from the floor

It is much easier to carry out measures for warming the veranda during the construction phase. As a rule, such structures are made according to frame technology. This facilitates the process of laying insulation in walls, floors and top floors.

The first stage of preparing the structure for winter living is the insulation of the floor on the veranda. After the foundation has been erected, a lower trim of a bar with a section of 150x150 mm is installed on the supports and the crate is mounted. Before insulating the floor on the veranda, the tree is treated protective composition.

Next, the so-called draft floor of the veranda from edged or unedged boards 25 mm thick is attached to the floor beam. In the presence of a subfloor, this problem is solved relatively easily. In the absence of the necessary space under the floor of the veranda, 30x30 bars are attached to the side planes of the ceiling in the lower part, on which the subfloor is mounted.

On top of the fixed boards, an insulating material and a layer of vapor barrier are installed. Since the lion's share of heat loss occurs through the floor, 2-3 layers of insulation are laid on the lower floor, alternating directions at an angle of 90 °.

Instead of slab or roll insulation, solid materials are used, for example, expanded clay is poured between the beams. A layer of vapor barrier is laid on top and the floor is finished.

We insulate the walls

The next step in warming the veranda is wall insulation. Vertical bars are attached along the perimeter of the floor and fixed with the help of jibs and transverse horizontal inserts. Walls are sheathed outside finishing material of one kind or another, after laying the vapor barrier.

Between the vertical posts, a heater is mounted in at least two layers.

As a rule, the thickness of the material allows you to not fix it additionally. It is enough to cut pieces of mineral wool 3-4 cm wider than the opening into which installation is planned.

After the vertical surfaces are insulated, the final layer of vapor barrier is sewn on and the interior walls are finished.

We work with the ceiling

It is impossible to qualitatively insulate the veranda from the inside, bypassing the ceiling. The upper frame is assembled similarly to the lower floor, that is, from wooden beams square section. In the case of sequential work, the ceiling is insulated before the installation of the roof. To do this, on the underside of the floor bars, a finishing sheathing of the surface is performed with a preliminary installation of a vapor barrier.

A heater is mounted on the finish in several layers and covered with a draft ceiling. If the veranda does not imply the presence of a separate roof with an attic, a crate is attached over the sheathing and the roof is installed.

Insulation of the finished veranda

It is much more difficult to carry out thermal insulation of a building erected several years ago. In this case, it is desirable to minimize dismantling work that can damage the previously installed finishing material of walls, floors and ceilings. Let us consider in more detail the nuances of warming the finished veranda.

Ceiling

If it becomes necessary to rebuild the premises for winter living, the installation of insulation begins with dismantling interior decoration ceiling. The operation is carried out carefully to minimize the amount of waste. As a rule, in wooden houses when decorating verandas, expensive material is used - lining.

After all the panels have been removed from the upper horizontal ceiling, the installation of the insulation begins. To prevent the fallout of mineral plates, proceed as follows:


Walls

As a rule, the insulation of the finished veranda is performed from the outside. This allows you to save expensive interior decoration. After dismantling the outer wall sheathing, a vapor barrier is installed: the film is fixed in the gaps between the uprights using a construction stapler.

Insulation of the veranda from the outside

Instead of mineral wool, foam plastic is used for external wall insulation, which is resistant to weathering and is not afraid of the influence of microorganisms. The insulation of the veranda with foam plastic is carried out in a pre-mounted crate, which provides free air circulation.

Particular attention is paid to windows. It is better to install two- or three-chamber double-glazed windows.

If the windows for the veranda have single glass, all joints are treated with a special adhesive-based insulation, and the frame landing sites are coated with sealant.

Floor

A large amount of cold air enters the room through the floor. Without high-quality thermal insulation, winter operation of the veranda is impossible, while heating costs increase significantly.

We begin work on laying insulation from dismantling floor covering. can be attached in several ways:


If there is a rough sheathing, a vapor barrier membrane is attached and expanded clay or mineral wool is laid. With a standard thickness of mats or rolls of 50 mm, it is recommended to lay 3 layers between a 150x150 beam. On the upper planes of the beams, a vapor barrier is fixed and the floor boards are mounted in their original place.

If there is no draft floor, a false lattice is made of a 30x30 pine beam, attaching it to the side planes of the beams with 70x4 mm self-tapping screws.

Thus, having studied the technology of warming the veranda, even a novice master will be able to independently perform all the work. Of course, it is better to insulate the room at the construction stage. But in extreme cases, you can make the insulation of the finished veranda, spending an additional amount of effort, time and finances.

In a harsh climate, the owners are trying in every possible way to insulate the house or cottage. For example, to protect the front door put a veranda. This is a kind of vestibule where cold street air is mixed with warm air from interior spaces. But, when insulating the house, they do not always take into account that additional insulation will not interfere with the veranda. Otherwise, the unheated room will freeze and damp, which will quickly make the finish unusable. With a competent approach, the veranda is insulated even at the construction stage. But it happens that the house was not built, but bought, and not in the at its best. In this case, the insulation of the veranda from the inside with their own hands is carried out as necessary. The main thing is to know in what places the cold "creeps" into the room, and to take all possible protective measures.

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

Options for insulating the base summer veranda, maybe several.

Backfilling the interior space with earth or expanded clay

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

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

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

Pasting with polystyrene foam

For Russian lands, where 80% of the soils are heaving, external insulation of the foundation with polystyrene foam 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 save the base from direct contact with the ground, and also blockade the frost. Expanded polystyrene boards paste over the entire outer surface of concrete, including the base.

Do-it-yourself veranda insulation is suitable for: 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, the foam pulls moisture from the ground, so when it is installed, an additional waterproofing layer is created (from the soil). Extruded polystyrene foam due to the dense structure, it does not absorb moisture, is not afraid of soil movements, has high frost resistance and lasts more than half a century. But it costs a lot.

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

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

The latest way of external insulation - polyurethane foam coating. It is brought to the construction site in the form of liquid components and sprayed onto the foundation with special equipment. After curing, the coating becomes dense, monolithic and very durable. According to the characteristics, this material is not inferior to the extruded "brother", but the cost of work is more expensive.

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

To keep your feet warm: floor insulation

In addition to 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 the verandas. If you plan to heat the veranda using the "warm floor" system, then you should take care of it already at the stage of pouring the subfloors. It is better to choose an electrical system that you will turn on as needed. The water floor can freeze at very low temperatures, and you will have to wait for spring to thaw it, or dismantle the coating to warm up the pipes.

If there was an old tile on the veranda, then you can put insulation directly on it

Consider how you can insulate the floor on an unheated veranda:

  1. The entire underground is covered with rubble, and on top - with sand and compacted tightly.
  2. Lay out reinforcing bars or mesh (so that the concrete does not burst) and make a concrete screed 5 cm thick.
  3. When the fill is tired, we create waterproofing. The easiest way is to coat the screed with water-repellent mastic. But it's cheaper - to lay sheets of roofing material and fasten them together using bituminous mastic (or warm it up with a burner and roll it).
  4. Logs impregnated with an antiseptic are mounted on top of the waterproofing, and insulation is laid between them. Most best option– mineral wool with a foil side. The foil does not release infrared radiation from the veranda, with which most of the heat escapes. Rolls of insulation are placed after all the logs are installed.
  5. You can also insulate with polystyrene foam. Then the joints between the plates must be blown out mounting foam, and when it dries, cut off the excess.

After that, boards or decking are laid, because both materials are warm. The board must be treated in every way from decay and painted with a protective compound. Besides, natural wood very afraid of poor ventilation. To avoid dampness, it is necessary to make ventilation vents in the foundation, which should be located below the floor level.

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

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

Decking is also a board, but already processed with compounds at the factory. It is made from larch, which is not afraid of frost or moisture. Open terraces are lined with such material, so it is all the more suitable for a veranda. True, the cost of such a floor will be expensive.

We put thermal protection for the walls

The walls have a large area of ​​​​contact with the street, so consider how to insulate the veranda with your own hands from the outside and from the inside. Outside, insulation is carried out if the material of the walls looks unpresentable. Those. it can be blocks, old wood, etc.

External insulation

and for wooden walls:

  1. We close all the cracks in the building.
  2. We fill a vertical crate of bars on a 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 plates will fit tightly to the crate.
  3. Insert between the bars mineral wool, fixing the 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, it is necessary to attach a waterproofing film to the crate with a stapler

b) For block walls:

  1. Glue on the walls polystyrene boards with a special adhesive composition, additionally strengthening the dowel-umbrellas.
  2. We coat the same glue on the top of the plates and fix the reinforcing mesh on them.
  3. After drying, we cover the walls with decorative plaster.
  4. We paint.

Choose an adhesive composition specifically for laying polystyrene foam boards

All layers of the insulation cake are hidden under decorative plaster.

We warm 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 insulating the veranda from the inside, it is necessary to carefully caulk all the cracks (in a wooden building).

Work progress:

  1. They are stuffing the crate.
  2. A waterproofing film is fixed with a stapler, which will not let moisture from the street into the insulation.
  3. Mounted metal carcass from profiles, on which drywall is then fixed.
  4. Fill the frame with mineral wool.
  5. Cover the insulation with a vapor barrier film.
  6. Install drywall.
  7. Inflict top 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, doors

Large heat losses can come from windows and doors. If there are old wooden windows on your veranda, but you do not want to change them to 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: for this, we pull each glazing bead.
  • If they are cracked or loose, then it is better to remove all the glasses, 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!).

Walk with an ordinary metal ruler at the joints of the frame and the window opening. If in some places it passes freely, then these slots must be sealed with mounting foam. Check the front door the same way. If you bought a non-insulated version, then you will have to insulate the canvas yourself from the inside and upholster it with leatherette.

By fixing the glass on both sides with sealant, you will make it impermeable to the wind

All places where the ruler moves freely must be foamed

We exclude the leakage of warm air through the ceiling

It remains to figure out how to insulate the ceiling, because through it a significant part of the heat escapes from the wooden veranda. Especially if it opens. Entrance door. A stream of cold air rushing inward instantly squeezes out warm air.

The best option is to lay a foil foamed polymer between the beams, which will simultaneously keep heat and prevent moisture from passing through.

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

Roofing material is laid under mineral wool for waterproofing

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

Country houses are in fashion today. Someone is a happy owner of a summer house, and many even prefer to live away from the bustle of the city. Of course, everyone strives to make their homes more comfortable and beautiful, so they decorate them with verandas and terraces. These extensions must be distinguished. If you do not go into the essence, then the terrace is an open area without walls, and the veranda is part of the house, but, as a rule, without heating.

In summer, such rooms are good for various gatherings, but with the onset of the cold season, they are no longer used. However, you can not deny yourself and your loved ones in the usual pastime. Warming the veranda will help keep it cozy at any time of the year. Of course, it is best to think about this at the construction stage, but even in a finished purchased house or in a veranda attached later, you can correct the situation.

So, it makes no sense to insulate the terrace, but you can take care of the comfort on the veranda. As a rule, insulation is a set of measures aimed at improving the heat-saving properties of walls, windows, ceilings, but you need to start from the floor, because the cold rises from below.

The procedure will depend on how the floor is made, which can be concrete, laid on a solid foundation, as well as wooden on supports.

Bottom insulation

Floor insulation on a concrete base

  1. Doing concrete foundation for the future veranda, you need to start work with backfill sand and gravel cushion. River sand (or another, the main thing is not to be fine and without clay impurities) is poured into the foundation pit and rammed. Then comes a layer of crushed stone or gravel, which also needs to be compacted.
    Such a cushion will not let the cold coming from below to the concrete slab, and will protect it from capillary moisture, which can rise through channels less than 0.5 mm wide. The thickness of the layers of sand and stone depends on the type of soil and structures being built.
  2. Over stone for greater reliability laying reinforcing mesh from rods with a cross section of 10-12 mm and pour the foundation with a solution based on frost-resistant concrete.
  3. Concrete is covered with a layer of waterproofing: roofing felt or similar material, and on top is laid insulation layer. For example, you can take mineral wool boards.
  4. The heater, in turn, is also covered a layer of waterproofing film, and already on top of all this “pie” reinforced concrete slabs are laid or a reinforced screed is made.

Such a foundation will be a good obstacle to the cold rising from the ground, and will also protect the veranda from dampness. In addition, the concrete floor allows you to take additional measures for warming.

Floor insulation on supports or piles

With this type of foundation, the floor is usually made of wood. Air circulates under it, so it will be very cold on the veranda in winter.

  1. Warming begins with measures to block access to cold air under the veranda. To do this, along the perimeter of the floor, marked with supports, you need to build a formwork.
  2. The second step is backfilling the resulting underground with expanded clay. On top of it, you can lay a film for vapor barrier and additionally lay insulation. Of course, before such actions, you will need to remove the existing floor.

basement insulation

External insulation of the foundation is another way to save the heat of the veranda. In addition, the soil, expanding or decreasing in volume under the influence of air temperature, can deform the foundation. Such a problem is solved quite simply, by gluing the base around the entire perimeter with a heater. Usually these are expanded polystyrene plates, which will become an obstacle to the cold, and also prevent contact with the ground.

A less budgetary, but more reliable option would be to use extruded polystyrene foam, which has the necessary strength, is not afraid of moisture and cold, and its service life is more than 50 years. Before gluing the insulation boards, the foundation is smeared with bitumen or bitumen-polymer mastic, which is not afraid of low temperatures.

There is another option to insulate the basement, the newest, expensive, but also reliable. This is a polyurethane foam coating. The liquid base is sprayed with special equipment on the walls, and after drying, the foam becomes solid, monolithic, without a single seam.

Top insulation

Such methods are good when you can’t get to the bottom of the foundation, but you still want to make the floor warm. However, even with an insulated foundation, thermal insulation measures will also not be superfluous. The main feature of all work with the finished floor is raising its level, which occurs due to the laying of various heat-insulating materials.

concrete floor insulation

Underfloor heating system

Since the veranda is not heated, this solution will be ideal for maintaining a comfortable temperature in the room. Moreover, an electrical system is recommended, and not a water one, since the cable is not afraid of frost, which cannot be said about pipes with water.

A rather time-consuming, but reliable option that requires the use of durable insulating material in the form of plates or mats. It can be expanded polystyrene, extruded polystyrene foam, mineral wool.


A wooden floor can be very beautiful, and country houses it is often customary to decorate with just such coatings. Wooden floors can be laid on any base, taking care of the insulation at the same time.


One of the insulation options is sprayed materials. This is quite expensive and requires the work to be carried out by specialists using special equipment. The use of such a heater will require cleaning the floor from debris, bitumen drips, grease stains and solvents. It is not necessary to lay transverse bars between the lags - the future spraying forms a fairly dense heat-insulating layer. The foam is applied with a special device that mixes a special liquid composition with carbon dioxide and sprays it under pressure.

The crate filled with insulation must be covered with another layer of film or penofol, a relatively new material, which is polyethylene foam on an aluminized substrate. It is laid with the substrate up and slightly crumpled into the cells so that there is space for floor ventilation.
Now you can lay the boards treated with an antiseptic on top, attaching them with self-tapping screws. The boards are located perpendicular to the lags, but instead of them, if desired, plywood or GVL sheets are laid, and only then - the finish coat.

Wooden floor insulation

There is an opinion that it is easier to insulate a wooden floor than a concrete one, but this is not entirely true. Of course, you don’t have to do a screed, but you still need to work hard.

Infrared warm floor

This is an alternative electrical cable, which fits into the screed layer and is therefore not suitable for wooden floors. The only requirement that must be observed for laying such a system is the non-toxicity of the floor materials when heated, and in all other respects this is a good option for maintaining heat on the veranda.

This method is the main one for warming wooden floors. In terms of the sequence of actions, it is similar to the previously described one, only the foundation is prepared differently.


In addition to all the methods described earlier, you can use the flooring of special types of linoleum or laminate, which are able to retain heat, as well as carpet.

Warming the floor on the veranda is the best thing to do in the process of building this extension, but with a special desire, you can start work at any time. It cannot be said that the complex of actions is extremely simple and accessible to anyone. The mere ability to hold a hammer in your hands will not be enough to do the job, but those who are confident in their abilities and have a little, but still building experience, may well do everything on their own.

The main thing is to choose the materials that are most suitable in terms of price and quality, because the success of any repair consists of two components: the skill of the workers and the quality of the tools and tools used.

Warming the veranda from the inside with your own hands 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 the veranda requires its insulation even at the beginning of construction. But if the house was bought, do-it-yourself warming of the terrace should be done if necessary.

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

The building can be finished:

  • Outside. Such work is best done only in good weather: when it is easier to work, and the materials used will not be damaged.
  • From within. This method is relevant in cool and even cold weather. In this case, you can immediately:
  1. insulate the veranda;
  2. prepare a good base for interior decoration.

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 can be:

  • Minvata.
  • Styrofoam. But in case of unexpected contact with fire, quite dangerous carcinogens will be released, which should not be ignored. However, the relatively low price makes the material affordable for warming such a room. Polyfoam is a budget option.
  • As an additional material, you can use a foam pad. Its metallized layer will be able to reflect cool air from the street, and heat will remain inside the veranda. This material is a high-tech, heat-insulating agent consisting of a layer made of polyethylene foam and high-quality aluminum foil covering it. Such a "reflected" layer can also be used as a separate independent thermal insulation. But for maximum effect, to preserve heat, it is necessary to combine foam phenol with other types of heaters.
  • Polyurethane foam, basalt wool, resole foam are considered effective options for insulating a building with your own hands.. These materials do not burn.

More about insulation

How to insulate the foundation

Tip: For the veranda, you should choose the same type of foundation as the main building - concrete slabs, cast-in-place concrete or strip foundation.

Base material absolutely does not block the cold going into winter period from the ground, so the foundation can freeze through. Through it, heat loss reaches up to 20%. There are several ways to insulate cold veranda, namely its base.

It could be:

  • Backfilling with earth or expanded clay of the internal space.

Such options are used only in the construction of the veranda, when foundation work is carried out. For this:

  1. the formwork is removed;
  2. the entire internal site is covered with expanded clay or earth, which will be very cheap, especially when excess soil remains after construction. But at the same time, the quality of its heat saving is low.

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

Tip: To isolate the base, a double layer should be made: the first is covered with soil, and then expanded clay pebbles are laid.

  • Pasting with polystyrene foam.

In the presence of heaving soil, it is necessary to carry out external insulation of the foundation walls with expanded polystyrene. This is due to the deformation of the base, which occurs due to the expansion of the soil in volume during periodic thawing and freezing.

In this case, the insulation layer plays the role of an insulator, relieving the base from direct contact with the ground, and blocking frost. The entire outer surface of the concrete, including the plinth, is pasted over with expanded polystyrene plates.


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

The order of work is as follows:

  • Polystyrene is laid on the outside of the foundation, which is dug up to the very foundation.
  • The first row is mounted on a gravel bed.
  • The base is smeared with bituminous polymer mastic, for a waterproofing layer.
  • After drying, expanded polystyrene plates are glued.
  • The adhesive composition is selected polyurethane, which is applied in dots or the entire sheet is lubricated.
  • Between the plates, the joints are taken with glue, which will make it possible to avoid cold bridges and save the base from 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 with special equipment. After complete curing, the coating acquires density, becomes monolithic and sufficiently durable.

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

How to insulate floors

Closest to the ground, in addition to the foundation, are the floors. Their insulation must be performed without fail in order to avoid the appearance of black spots of dampness in the corners.

On the verandas, the floors are usually poured with concrete. When planning a heating device using the "warm floor" system, it should be carried out on initial stage floor fillings.

In this case, it is better to choose an electrical system that turns on as needed. At sufficiently low 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 is an old tile on the veranda, the insulation can be placed directly on it.


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

  • The entire area of ​​​​the underground is covered with gravel.
  • Sand is poured on top and carefully compacted.
  • Rebars are laid out for reinforcement or a mesh is laid out, which will protect the concrete from cracks.
  • Is being done concrete screed five centimeters thick.
  • After the fill hardens, 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 sheets and fasten them bituminous mastic or rolled, pre-heating them with a burner.
  • On top of the waterproofing, logs impregnated with an antiseptic are mounted, and a heater is laid 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 escapes. Insulation rolls are laid after installing all the logs.
  • Insulation can also be performed with polystyrene foam. At the same time, the joints between the plates are blown with mounting foam, and the excess material is cut off after drying.
  • Boards or decking are laid.

Tip: All wooden details must be carefully treated with antiseptics that protect them from decay, and then painted with a protective composition.

  • To avoid dampness, which the tree is very afraid of, good ventilation is organized. To do this, ventilation vents are made in the foundation, located below the floor level.
  • Insulation is placed with the foil up, which prevents heat from reflecting back to the veranda.
  • Underground decking does not require ventilation - 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. For its manufacture, larch is used, it is not afraid of frost and moisture. Such material is usually lined with open terraces. But, the cost of such flooring is quite high.

How to insulate the walls of the veranda

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


When insulating wooden walls, you must:

  • Close up all the cracks in the building.
  • On a tree, fill a vertical crate from the bars with a step of elements up to 0.5 meters.

Tip: When stuffing the rails, measure the width of the insulation, and then fill them exactly according to its dimensions. In this case, all the plates will fit snugly against the crate.

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