Preparing the loggia for insulation in a panel house. How to insulate a loggia or balcony in a panel house: secrets and nuances. The main stages of thermal insulation of a loggia or balcony

Most of the apartments in panel houses are complemented by loggias. These external structures are used in different ways. Their functionality depends on the presence of glazing and insulation. Open balconies and loggias can be actively used only in the warm season, but even in this case, precipitation and wind cause a lot of inconvenience.

Rice. 1 Insulation of the loggia in panel house- scheme

Glazing will protect the balcony space from precipitation and other negative factors, but without insulation of all surfaces, the winter temperature will be too low and uncomfortable. Thermal insulation will make the space more functional and comfortable if you know how to insulate a balcony in a panel house.

Preparing the balcony for insulation

Before you start insulating balcony design, you need to prepare it. Preparation includes clearing away debris and removing old trim and glazing. If necessary, the balcony in the panel house is repaired. There may be a need to strengthen balcony slab, frame replacement.

Even if major repairs to the balcony are not required, chips, cracks and potholes still need to be repaired. Any depression will become a place where moisture will accumulate. Only when the insulation fits tightly to the surface to be insulated can condensation be avoided.

Rice. 2 Start of repair of the loggia in the panel house

Surface defects are repaired suitable compositions. It is better to use sealant and polyurethane foam for cracks, and cement mortar for potholes.

Balcony glazing can also be called preparation for insulation. The characteristics of the frames and the glass part largely determine how reliable the thermal insulation will be.

Glazing is made of plastic, aluminum or wooden frames. Wood and plastic insulate well. Aluminum profiles practically do not retain heat if they do not have a special insulating filling.

Most often, frames made of plastic profile. The more internal air chambers there are in the profile, the better it protects against heat leakage. But at the same time its weight increases. When choosing frames for glazing a balcony, you need to find a balance between these two characteristics, because Load-bearing structures should not be overloaded.

The frames are complemented with single glass or double-glazed windows. The second option provides a higher level of thermal insulation.

Materials for insulating balconies

After glazing a balcony or loggia in a panel house, insulation materials are selected. During the selection process, the installation method and operational characteristics are taken into account.

Most often, mineral wool, penoplex, polystyrene foam and penofol are used to insulate balconies. Materials differ in their density and methods of fastening.

Rice. 3 Basic thermal insulation materials

Mineral wool is used only if there is sheathing. Foam plastic and penoplex can be installed frame method or attach directly to the surface.

It influences the choice of heat-insulating material and the nature of subsequent finishing. If cladding with sheet materials is used, then it is necessary to install a frame. You can perform plastering work on glued polystyrene foam and penoplex.

Rice. 4 Balcony insulation with mineral wool

The procedure for insulating a balcony ceiling

There are many options for insulating balcony ceilings, but the procedure is approximately the same.

First, the surfaces are treated with a primer that protects against mold. Foil material is glued to the prepared ceiling. It could be penofol. The material can be glued with PVA or tile glue, as well as polyurethane foam. It is important to ensure that the insulation fits tightly to the ceiling.

Rice. 5 Balcony insulation - use penofol for the ceiling and walls

A sheathing is installed on top of it. Finishing material is attached to this frame.

As insulation, you can use polystyrene foam, which is attached to the ceiling or installed between the sheathing elements, as well as mineral wool.

Thermal insulation of walls and floors on the balcony of a panel house

When figuring out how to insulate a balcony from the inside with your own hands, we highlight two methods. The first option is to attach polystyrene foam or penoplex without a frame, directly to the wall surface. To insulate a loggia in a panel house, slabs of material are glued and additionally secured with dowels. The advantage of this type of installation is the absence of space between the wall and the insulation. As a result, condensation does not form on the wall under the insulating material.

Rice. 6 Wall insulation option

This insulation option also has its disadvantages. Firstly, the walls must be perfectly smooth. Secondly, only plaster or those few can be used as finishing Decoration Materials, which are glued to the surface to be finished. Most cladding options require sheathing.

Another way to insulate a loggia is with a frame. The sheathing is made from timber of the required thickness. Next, mineral wool or foam sheets are laid. The materials are secured with dowels. The gaps between the supports and the foam sheets are sealed with polyurethane foam. Mineral wool does not form cracks due to its elasticity.

A vapor barrier is fixed over the insulation. Next, cladding is performed with selected materials.

Insulation and arrangement of the balcony floor is carried out in the same way. The surface is waterproofed so that moisture from outside does not penetrate into the insulation.

Then the logs are laid on the floor. Insulation is placed between them: mineral wool or penoplex. It is better not to use polystyrene foam, because... it is sensitive to mechanical stress.

A vapor barrier is placed on top of the insulation layer and closed. sheet material, which forms the subfloor.

The work is completed by laying the floor covering.

Rice. 7 Attractive balcony design in a panel house

The result of insulating and finishing a balcony in a panel house with your own hands is an attractive interior and comfortable conditions. In order for the result to correspond to the expenditure of effort and money, you should find out how to properly insulate the loggia.

Knowing how to insulate a balcony in a panel house, you can effectively block the access of cold air to the apartment. After all, with the onset of frost, it is from there that it penetrates into the living space. You can complete all the work using wide range heat-insulating materials and without recourse to the services of specialists, that is, with your own hands.

What is it for?

The loggia can be turned into a warm office

At the beginning of the article it was already said that if you insulate a loggia in a panel house, this will serve as a barrier to the cold from the street. It should also be recalled that reinforced concrete has a high degree of thermal conductivity, and this negatively affects heat retention. Additionally, the small space can be used in many different ways. The first option is to connect the balcony with the adjacent room. The second is to use it for its intended purpose and design a separate room in its area.

The warm loggia will become excellent option for a place of rest and relaxation after a working day, ideal option a schoolchild doing his homework here, because the best lighting is natural, sunny. And if you install a computer and a desktop, the room can turn into an excellent office. In general, we can say that there are a lot of arrangement options. The only thing left to do is to insulate the balcony with your own hands.

Required scope of work

Insulate the floor, walls and ceiling

When thinking about the question of how to insulate a balcony in a panel house with your own hands, you should evaluate the scope of work that will need to be completed to achieve your intended goal. There are several main stages:

  • Floor insulation.
  • Ceiling insulation.
  • Thermal insulation of walls.

It is worth emphasizing right away that it is best to perform this procedure with outside. But in some situations, installing thermal insulation with outside impossible. For example, if an apartment is located on the upper floors of a building, this can be life-threatening. Not everyone will be able to work using scaffolding (depending on what floor the apartment is located on), and hanging over the handrails during installation is a direct violation of safety regulations. Based on this, we next consider options for how to insulate a balcony from the inside with your own hands.

Many balconies in panel houses built in the last decade already have the necessary thermal insulation. For fencing, structures made of gas are used here. concrete slabs with internal reinforcement tie. If a wall made of this material meets the climatic requirements of the region, insulation will not be needed.

Choice of insulation

Before choosing insulation, you should first decide how the loggia will be insulated. This is due to the fact that some types of work require the use of a certain category of insulation. Therefore, below are the most alternative views heat insulators offered on the modern construction market:

  • Mineral wool.
  • Expanded polystyrene.
  • Extruded polystyrene foam.
  • PVC foam.
  • Polyurethane foam.
  • Polyurethane mastic.
  • Bulk expanded clay
  • Polyuria (polyurea).

The main coefficients regulating the composition of thermal insulators are considered to be 3 characteristics:

  • Density.
  • Thermal conductivity.
  • Vapor permeability.

The table below shows the average coefficients of these insulation categories.

Insulation category Density coefficient, kg/m3 Thermal conductivity coefficient, W/(m*C) Vapor permeability coefficient, mg/(m*h*Pa)
Mineral wool 50 — 200 0,048 – 0,070 0,49 – 060
Expanded polystyrene 33 — 150 0,031 – 0,05 0,13 – 0,05
Extruded polystyrene foam 45 0,036 0,013
PVC foam 125 0,052 0,23
Polyurethane foam 30 — 80 0,020 – 0,041 0,0 – 0,05
Polyurethane foam mastic 1400 0,25 0,00023
Expanded clay (bulk) 250 — 800 0,10 – 0,18 0,50 – 0,70
Polyuria (urea) 1100 0,21 0,00023

Insulation of a loggia in a panel house

According to the data, you can choose the right quality material in order to insulate a loggia in a panel house with your own hands.

To correctly answer the question of how to insulate a balcony from the inside with your own hands, it is enough to follow a simple procedure. In this case, the frequency can be ignored and the work can be done in any order.

It is assumed that the loggia is already glazed with good double-glazed windows.

Floor insulation

One of the important criteria in how to properly insulate a loggia is proper thermal insulation of the floor. This can be done using various heat-insulating materials: from bulk expanded clay to mineral wool or extruded polystyrene foam. Initially, for this you need to lay it on the floor wooden joists or timber, which must be treated with an antiseptic.

The location of the so-called sheathing is carried out strictly horizontally. This will simplify subsequent work. Heat-insulating material is placed (or poured) into the resulting cells. The next step is to cover the entire area with sheets of plywood, chipboard or OSB, on which the facing floor material is laid:

  • Laminate.
  • Linoleum.
  • Parquet.
  • Tile.

The final aspect of insulation in how to insulate your balcony is the installation of a heated floor connected to a heating system, or the installation of a similar independent system powered by an electrical medium.

Ceiling insulation

Distribute the insulation over the entire ceiling area

How to insulate a loggia from freezing of the ceiling slab during cold weather? It is necessary to insulate it. It is done like this: galvanized hangers are fixed to the surface using dowel nails. Having bent the technological edges, a thermal insulation board is pushed through them. If the density of the material is sufficiently rigid, you can perform this action one by one, piercing one hole at a time. Thus, the insulation is distributed over the entire ceiling area.

In order to insulate the loggia from the inside, a wooden beam or galvanized profile is fixed to the protruding edges of the hangers. This is done along a previously stretched rope, which should be positioned strictly horizontally, parallel to the floor surface. The interval between the elements of the sheathing should not exceed 40 cm. Otherwise, the decorative material may bend under the influence of time. The location of the beam is determined depending on the chosen method and type finishing. If, for example, PVC panels are used, they will be fixed parallel to the window, the sheathing should be positioned perpendicular window opening. For more information about insulating a balcony, watch this video:

As a ceiling decorative finishing can be used the following types finishing material:

  • PVC panels.
  • MDF panels.

When choosing drywall, keep in mind that in the future it will need to be wallpapered, painted or applied decorative plaster, which requires some financial expenses, time and effort.

Wall insulation

It is difficult to imagine insulating a balcony without thermal insulation of the walls. If the floor and ceiling can have a relatively positive temperature due to the fact that they are insulated by neighbors above or below, then the wall partition goes directly to the street. The procedure in this case is similar to the work on ceiling insulation. Special hangers are fixed to the wall, which are bent and insulation boards are placed through them. Using expanded polystyrene or polystyrene foam, it is advisable to foam the resulting seams between the panels with polyurethane foam.

IN Do you have to forget about the balcony in winter? It's time for a change - turn your warehouse of unnecessary things into a warm one cozy corner or even ! Insulate cold balcony both in a new building and in a private house it is not as difficult as it seems: it is enough to know what materials can be used and in what sequence the insulation work should be carried out.

To begin with, it’s worth saying that there are two ways to insulate a balcony – from the inside and the outside. External insulation, of course, is more convenient - precious centimeters of space are not “eaten up”, and the cladding of the balcony facade becomes more pleasant. But this labor-intensive process, which requires attracting construction crew and industrial climbers. Therefore, in this article we will focus on how to properly insulate a balcony in an apartment from the inside - you can do this yourself.

To insulate the inside of the balcony, you first need to carry out preparatory work. They include several important steps:

  • Where to start insulating a loggia or balcony? Free up space from everything unnecessary. It’s best if the balcony is completely empty: it’s much easier to work this way. Also, get rid of old trim in advance.
  • Seal all the cracks - a lot of heat escapes through them. For small gaps, a weather-resistant sealant is suitable; fill larger ones with mounting foam - it will not only fill the voids, but will also serve as an additional heat insulator.
  • To make it easier for you to carry out insulation work, it is important to level out cracks and unevenness on the walls and ceiling using cement mortar.
  • If you plan to place light bulbs or lighting, it is worth taking care of the wiring in advance. To hide unsightly cables, place them in plastic boxes.
  • Before starting work, cover the opening between the balcony and the adjacent room with film to prevent construction dust and other pollutants from entering the apartment.

Is it possible to insulate a balcony in winter? Yes, you can. Only when carrying out work in winter is it necessary to choose frost-resistant materials, in particular polyurethane foam.

How to insulate a balcony: what materials are best to choose

To understand how to insulate a loggia or balcony, let’s first figure out what properties the materials should have:

  • high strength;
  • fire safety;
  • water resistance;
  • environmental friendliness;
  • relatively low cost;
  • ease of installation (if we want to do all the work ourselves).

Most often, mineral wool, polystyrene foam, polystyrene foam, etc. are used for insulation. Sometimes several of these materials are combined. We have reflected the pros and cons of each heat insulator in the table:

Insulation Advantages Flaws

Rarely used as an independent heat insulator, usually only in combination with other materials

Which insulation for a balcony is better? The answer to this question depends on your preferences and financial capabilities. You can read more about the characteristics of insulation, as well as in general, in our blog.

First you need to lay it on the floor waterproofing layer made of polyethylene or penofol so that dampness does not bother us. Craftsmen advise laying penofol with the reflective side up. At the same time, we can attach the waterproofing material to the walls. It is better to glue the joints between the sheets of waterproofing with foil tape.

Another good waterproofing agent is bitumen-based mastic. It dries for about a day; surfaces treated with it should not be touched.

Then we install logs - wooden beams or metal beams, serving as the basis for floors, platforms and other surfaces. Wooden logs are suitable for floor insulation. You should choose logs made from high-quality materials: the moisture content in the wood should not exceed 12%. Also, in order to prevent fungus and rotting, the beams are treated with an antiseptic or primer.

The distance between the logs should be equal to the width of the insulation, and builders recommend making the height of the beams 10-15 centimeters - this is necessary for reliable protection floors from frost. To seal the holes between the joists and the wall, and also to secure the beams in the desired position, use polyurethane foam. Don't worry about being careful: excess foam can be cut off with a knife after it dries.

Further stacked thermal insulation layer, slab or fiber. Make sure that there are no gaps between the heat insulator and the joists: “cold bridges” will negate all your insulation efforts. If you are laying insulation in several layers, be sure to move each new layer so that the seams between the insulation sheets are not in the same place.

To protect the floor from condensation, you will need a layer of vapor barrier.

Using self-tapping screws, attach a “sub-floor” made of boards, sheets of plywood, fiberboard or chipboard to the joists. This is the last step before finishing a floor such as laminate, linoleum or carpet.

There are two technologies for insulating the ceiling - with or without a frame. Before starting work, it is recommended to apply an antiseptic layer to the ceiling: this will protect the surface from mold.

If you decide to make a sheathing, you will need wooden blocks and dowels. We put insulation into the sheathing - mineral wool or polystyrene foam is suitable as a thermal insulation layer. Mineral wool is secured with polyurethane foam, and the foam holds without additional fastening. Then the ceiling is finished: plastic panels, drywall, lining - any materials will do, it all depends on your idea.

Without a frame, ceiling insulation work is carried out as follows: the ceiling surface must be cleaned of dust and dirt, and also treated with strengthening primer - this will help fix the insulation more reliably. Then the glue is applied to the foam sheets (it is enough to apply glue along the perimeter and a little in the middle). We glue the sheets to the ceiling; for reliability, they are attached using dowel mushrooms. We seal the joints with polyurethane foam.

The glue you will use should under no circumstances contain toluene.

We already have the waterproofing ready, so we can immediately install the sheathing made of wooden blocks. The distance between them should be equal to the width of the heat insulation, and the height of the bars should be equal to the width of the insulation. For walls, polystyrene foam boards, polystyrene foam or high-quality mineral wool are suitable. As always, we fill the joints between the insulation with foam. A vapor barrier film must be secured over the insulation.

As a rule, the wall between the balcony and the room is insulated in one layer, and the remaining walls in two layers, or the thickest heat insulator is used.

What to do with the windows?

Think about it: is it worth insulating a balcony with cold glazing? If you want a truly warm corner, you shouldn’t skimp on windows. You can insulate the ceiling, floor and walls to the highest standard, but cold air will still leak through old or low-quality double-glazed windows.

If your balcony is not glazed, first of all pay attention to the parapet - a low wall that protects the balcony from the street. It must be strong enough to support the window structure.

Which windows to choose? If you plan to make the balcony a living room, two-chamber plastic windows with hinged doors. They are more airtight than sliding ones window systems, such windows also have better heat and sound insulating properties. The only negative is that since the balcony area is generally small, the arrangement of furniture may interfere with opening the windows.

In general, you can install plastic windows yourself. But it’s better not to take risks if you don’t have experience: after all, even some companies specializing in window installation make annoying mistakes in their work. In order not to encounter would-be installers, frozen windows, etc., be sure to read the reviews of people who have worked with this or that company.

If installing new windows is still not possible, it is quite possible to find another way out. on the balcony easily using available materials.

Even a perfectly insulated balcony can be a little cool in winter. To make it comfortable for you to be on the balcony on the coldest days, the ideal option would be electric heater. Usually it is placed near the wall separating the balcony and the apartment. You should not place a heater near the windows, otherwise the glass will start to fog up.

Conduct central heating You are not allowed on the balcony: this is prohibited by building codes.

Also good decision For heating there will be an electric heated floor or a water floor. Modern technology heated floors will delight you as long as the balcony itself will exist. Many systems are equipped with a thermostat, so you can set a comfortable temperature.

After you have done everything necessary work regarding insulation, care should be taken. If you have sealed all the cracks on the balcony, fresh air there will simply be nowhere to take it from. Therefore, regularly is extremely important. At a minimum, you can just open the windows.

How to insulate a balcony from the inside with your own hands in a panel house? It is often cool in apartments located in panel buildings due to fairly thin walls and poor thermal insulation. If you have a loggia, insulating the balcony can be a good solution to this problem; in addition, this allows you to expand the usable area. There are currently a large number of materials on sale with which you can perform this operation yourself.

Why is it cold in a panel house?

Its cellular structure retains heat well and does not allow sound to pass through, since the partitions between the cells dampen heat transfer and sound vibrations.

Available in a variety of options, varying in thickness - from 20 to 200 mm and density - from 15 to 50 kg/cub.m. The density of the foam should be selected based on need. If it is covered on top with additional plywood or other strong material, then you can take a lower density, since the higher the density of the foam, the worse it retains heat.

High-density polystyrene is stronger and easier to install and secure. It will help smooth out the unevenness of the walls, and not just insulate them. But the best option for leveling is extruded polystyrene foam.

Extruded polystyrene foam

Extruded or extruded polystyrene foam and polystyrene foam, although they consist of the same substance, differ in the technology for creating granules. At elevated temperatures, the granules are mixed and squeezed out of the extruder, due to this a uniform, closed-porous structure is formed, which has a high density.

This material can even be used when covering the floor, as it does not deform under strong pressure, levels and supports the surface.

In terms of thermal insulation and lightness, extruded polystyrene foam is better than conventional foam. Also one of its advantages is low flammability.

The sheets have a thickness of 20 mm and usually have a special groove for joining, which makes it possible to achieve a uniform coating without cracks and facilitates installation. Additionally, they need to be secured with polyurethane foam or “ liquid nails" Easy to cut with regular construction knife.

The only drawback of this material is its high price, but usually the floor area of ​​the loggia is quite small, so in this case better to spend it.

Polyethylene foam

Foamed polyethylene is an elastic elastic fabric, available in rolls, sheets and strands. Thickness from 2 to 20 mm. Thin polyethylene foam is usually used as a backing for laminate flooring, and the densest one is used as insulation, alone or in combination with other materials.

The most efficient polyethylene foam is covered with foil, which allows heat to be thrown in the right direction - towards the room. It is important to follow the rules for laying the heat reflector - with the foil side facing the room.

Polyethylene foam sheets are mainly used for the production of rugs of various thicknesses, for example, for tourism or children's games; it is not very convenient for insulating floors and walls.

Preparing the premises for insulation work

Before choosing insulation, you need to decide on the thermal insulation technology, but first of all you need to prepare the balcony for repair, since the preparation is the same in any case, no matter what method you choose.

Don't ignore preliminary procedures and do not skimp on them so that the insulation is of high quality and does not have to be redone in a few years. Proper preparation is necessary to prevent moisture from getting under the insulation, which will cause it to begin to deteriorate, lose the qualities for which you chose it, and become ineffective.

The algorithm for preparing surfaces for insulation is as follows:

  • First, thoroughly clean the walls, ceiling and floor of old paint, various irregularities in concrete, bumps, etc. Crushed, breaking concrete must be removed before flat surface.
  • Then the floor is carefully cleaned until it is absolutely clean. Large debris can be collected by hand, but dust must be sucked up with a vacuum cleaner to detect various cracks in walls and slabs.

Now you can start sealing holes, crevices and holes

  • Visible to the eye the cracks are expanded, cleaned, if necessary, moistened with water and filled with cement mortar or sealant
  • The gaps between the plates also need to be enlarged, moistened with water and filled with foam.
  • In addition to the damage listed above, cracks, dents, and small potholes may form in the concrete. They will not interfere with fixing the base evenly, but when the temperature changes, condensation may accumulate in them. Therefore, they need to be leveled; this can be done using cement mortar with the addition of PVA glue.

After all the covered defects have dried, you need to cut off the excess foam and remove the remaining sealant. Afterwards, it is necessary to prime all surfaces to protect against mold and strengthen the surface.

Surface waterproofing

At the next stage, you need to protect the floor and lower part of the walls from water. The walls must be waterproofed to the height of the final floor installation.

There are several main methods of waterproofing:

  • Covering the floor with roll materials that do not allow moisture to pass through, for example roofing felt, which is glued “hot” onto the bitumen mastic. Currently, there are roofing felt with a prepared glued mastic layer, which is heated with a burner.
  • Penetrating waterproofing is a special composition for impregnating concrete. If you are going to lay tiles on the floor, then this method is not suitable. The effect of such protection against moisture is based on the fact that it penetrates the cellular structure of concrete and forms crystals that fill the pores of the material from the inside. The crystals become part of the concrete, compacting its structure and preventing water penetration. Since the composition is very toxic, it must be applied extremely carefully, protecting exposed skin, otherwise you may get burned.
  • For tiles, it is recommended to use liquid rubber - a two-component mastic that is cold applied and quickly hardens. It is applied with a roller or wide brush. Freezing liquid rubber forms a kind of thin moisture-proof film on the floor and walls.
  • Waterproof plaster mixture, which is applied with a wide brush, or, if necessary, with a spatula suitable size.
  • Inexpensive way- thickly grated Oil paint, which is easy to apply and hides minor flaws, but is quickly absorbed by concrete, which increases its consumption
  • A time-tested method is to cover the floor with thick plastic film, making sure that it completely covers the height of the future floor and fits correctly in the corners. The film should form something like a bowl that will protect the insulation. Secure it with construction tape or liquid nails.

You can choose any method based on your preferences and budget. They all do their job main function- do not allow water to penetrate into the room, which means they reduce the likelihood of black mold, which is very difficult to fight.

Glazing

Currently the most common are window designs three models:

  • metal-plastic - the most common, characterized by a long service life and high tightness, and are relatively inexpensive. Among the disadvantages, we can note that they are not environmentally friendly, compared to wooden structures.
  • wooden - modern, sealed, well protected from the cold and can be made in any configuration, but quite expensive
  • , if you are going to use the balcony as a living area, since they are not airtight and do not protect well from the cold

Ceiling insulation

Foil backing for sheathing

It is mounted on construction tape with two adhesive sides or on universal Moment adhesive, which is evenly distributed over the ceiling in small dots and the insulation is pressed against it. It is best to use sheets for this purpose that need to be bent onto the walls by approximately 150-200 mm for additional waterproofing of the joints. Check that the insulation is securely fastened, as the sheathing will be installed on it.

The sheathing can be made either from a galvanized metal profile for drywall, or from a wooden beam - both are suitable for laying mineral wool or polystyrene foam.

The distance between the fastenings of the sheathing elements depends on the width of the insulation; it is desirable that it be close together, without gaps. Because mineral wool elastic, then for it this interval can be reduced by 30-50 mm for a good tight installation.

Laying insulation in sheathing cells

At the next stage we lay the insulation. The mineral wool will become tight between the beams, especially if you followed the advice and shortened the interval, but polystyrene foam is a hard material, so small gaps may remain. To prevent the penetration of cold, they need to be filled with polyurethane foam, the protruding parts of which will need to be cut off after drying.

Installation of slabs directly on the ceiling

Installation is carried out using special plastic mushrooms. For them, holes are drilled in the concrete directly through the insulation, into which the fungus is inserted, and then a plastic nail is carefully driven in.

Insulating the loggia floor

To insulate the floor, you can also choose various options: dry screed, lifting with joists, or simply laying a concrete floor extruded polystyrene foam. The latter action is not effective in maintaining the temperature on the balcony as in the rooms, it will simply make the floor not too cold.

Expert opinion

Konstantin Alexandrovich

Ask a question to an expert

The most highly effective and most frequently used method is insulation using logs.

The joists can be laid directly on the concrete floor or adjusted in height using various devices - metal holders, studs, adjustable or homemade coasters.

Metal holders lift the guides and this good way fastening joists, if their height is sufficient for installing insulation. For a standard loggia (size 3*1.2 m), three rows of logs will be enough.

The holders are attached to concrete and insulation is put on each. Mineral wool is most often used in combination with such fastenings. A square is cut from it, in which two holes are made, through which the insulation is put on the rack.

Having secured the logs in the holders and checked the horizontality, we lay the main insulation over the entire floor area. To achieve a better effect, place another layer of mineral wool, almost to the level of the joists.

Using staples, secure the vapor barrier film on top of the insulation to the joists.

The logs are covered with 10 mm thick plywood on top, and all cracks and crevices are filled with polyurethane foam. After drying, the excess foam is cut off and laid on top of the plywood. decorative coating.



  • If you do not plan to use the balcony as a living space, but simply want to raise the temperature there so as not to let cold air into the apartment, then raising the floor to the threshold level is not required. It will be enough to lay the insulation to the height of the logs, fixed to thin polyethylene foam laid on concrete.

Under these conditions, the joists are drilled through and secured using anchors. The space along the walls and between the joists is filled with insulation and covered with a vapor barrier and plywood.

Insulation of loggia walls

Insulation of walls is done in the same way as on the floor or ceiling of the loggia. Here, too, you can choose a method to your liking - use wooden or metal sheathing or rigid insulation that is attached to the walls special glue or polyurethane foam.

  • Installation of penoplex will be easy if you prepare the panels of the required size in advance. All vertical surfaces are faced equally - on reverse side Apply glue to the insulation and press it firmly to the wall. For additional fastening, you can fix the panels using plastic mushrooms.

But still, a more popular option, which is suitable for any thermal insulation material, is the method using wall lathing wooden beam or metal profile.

Before installing the sheathing, to increase efficiency, it is recommended to make a polyethylene foam backing with a foil surface.

  • Such a substrate will create a “thermos” effect and will reliably retain heat on the loggia. Next, the sheathing is fixed on top. The guides should be placed at a distance equal to the width or length of the insulation mats.

Installation of sheathing

The selected heat insulator is laid - foam plastic or mineral wool, it is covered on top with a vapor barrier film, secured with staples on bars or, when using metal guides, with liquid nails along the upper and lower edges.

Foam insulation

And finally, the final stage - sheathing decorative material, for example, clapboard, or plasterboard for painting or plaster.

Insulation with polyurethane foam

Most modern way insulation is sprayed polyurethane foam. In most cases, it is practiced for insulating the inside of roofs and outside walls in private houses and cottages, but since this method is characterized by speed and ease of installation, it is increasingly used on balconies and loggias in city apartments.

The only thing is that this method cannot be carried out independently; spraying is carried out only by professional specialized companies using special equipment.

Before entrusting your loggia to professionals, it is necessary to make additional preparations in the room, that is, make lathing, as described in the article above. The lathing will serve as a frame for the heat insulator and fastening on top of the decorative trim.

The great advantage of this method is that when sprayed, polyurethane foam expands and fills the entire space without leaving any gaps. It can be used not only on walls, but also on floors and ceilings. The surface becomes completely windproof, that is, it retains heat perfectly. Plus, you are spared the need to carry out additional inspection and fill cracks and cracks with polyurethane foam; you can immediately begin finishing.

Loggia design solutions

Let's see how you can use additional area resulting from insulation of the loggia. In practice, you have one more room at your complete disposal, and only you can decide what it will be like.

For our part, we can offer several ideas on how to use the new opportunities.

The warmest transformation - the loggia turns into a cozy little corner for relaxation. Here you can enjoy the silence with a good book or crafts. If necessary, there is enough space to install a TV or a small table for a laptop.

If a large family lives in an apartment, it is sometimes difficult to find a comfortable, quiet place for your favorite activity. Despite the small space, your new insulated loggia will allow you to place even two separate corners for activities dear to your heart. For example, a cozy deep chair can be placed in one corner, and a small table for a laptop in the second.

Very stylish modern version, suitable if the exit to the balcony is from the kitchen. You can even transform the loggia into a kind of dining room.

Ideal for parties, especially when high floors and an attractive view from the window, the window sill can easily replace the bar counter.

Using small details, such as lit candles, you can create the atmosphere for a romantic dinner. Fresh fragrant air and watching the sunset warm summer days, and in winter - cozy blankets, candles and mulled wine.

If you install glass sliding doors instead of standard ones, you can delimit the space if necessary.

Bold design solution proposes to expand the living room space onto the loggia. The wall that previously separated the rooms has been converted into comfortable table.

Zone former loggia in this case it can be used as a study or hobby room.

By combining two spaces, the living room provides access to large window, which increases illumination, you will feel this well in winter, when there is always not enough light.

It is not difficult to come up with the use of additional warm space, everything is limited only by your flight of imagination. Winter Garden, workshop, office, even a sports corner - everything is doable.

Therefore, if your apartment has a loggia, and you still haven’t thought about insulating it, get down to business urgently.

Let's sum it up

Properly insulating a loggia on your own is not so difficult; anyone can do it. Although this process includes a sufficient number of serious steps, by following the tips and rules described above, you can easily cope with insulating your balcony.

Independent connection and insulation of the loggia is a whole story with additional construction, complex technologies and a sea of ​​paperwork. And with an unpredictable result: it happens that after all the work, the insulated wall sticks out from under the glazing, the window handles are too high, and condensation drips from the ceiling. We will tell you how to make a loggia a full-fledged part of the apartment and not regret it!

Mistake 1: reconstruction and redevelopment without permission

Even if you do not want to demolish the wall between the apartment and the loggia, but only want to insulate the space outside the window, it is better to notify the BTI representative of your intentions - so that later you do not have problems, for example, with selling the apartment if there are inconsistencies in the technical passport of the housing.

InMyRoom tip: glaze the balcony using sliding double-glazed windows aluminum profile– and thus equip a summer unheated loggia. This measure will still add space (for example, for storage), and there will be significantly fewer drafts from the balcony. No permit is required for such glazing.

Error 2: moving the radiator to the loggia

If you have received permission to rebuild, then you are unlikely to plan to pull off such a trick. But in any case, know that it is not necessary to remove the pipes for the radiator and the battery itself. external wall buildings are not permitted. The heat loss on the loggia is too great; if the pipes are not insulated correctly, they can freeze, and accidents are possible; For the heat supply of recently uninhabited meters, one would have to pay an additional significant amount after individual recalculation. One way or another, the batteries are not transferred to the loggia - remember this at the design stage of the insulated balcony.

InMyRoom tip: An electric floor heating system or an oil radiator will help you - it can be attached to the wall in the same way as a regular battery.

Mistake 3: installing frameless glazing

Frameless doors look great - when closed they have a smooth surface, sometimes not disturbed even by edges. In addition, the doors are conveniently assembled “into an accordion” without taking up the space of the loggia. However, this solution is not suitable for an insulated balcony: single glazing and gaps between the panels cannot protect against the cold. In addition, dirt and dust quickly accumulate on them, fingerprints remain and the mosquito net does not attach.

InMyRoom tip: take a closer look at the latest developments– for example, to thermally insulated tilt-and-slide windows. But best choice for glazing warm balcony PVC double-glazed windows with good old swing doors remain. In fact, they do not take up much space - they can only be opened for ventilation, and opened twice a year to wash the glass outside.

Error 4: remote glazing on brackets

In an effort to increase the area, or more precisely, the volume of the attached loggia, apartment owners build a frame for glazing with a projection of several tens of centimeters. A wide canopy appears along the upper perimeter, on which snow constantly accumulates, and in the off-season rain loudly beats on it. The most important thing is that a glass growth appears on the facade, which spoils the appearance of the building.

InMyRoom tip: an alternative is possible only within the framework of façade uniformity. If your house is completely open balconies(or they should, in fact, be so) – it’s worth parting with the idea of ​​joining or even just glazing. And improve the loggia with green plants.

Mistake 5: insulation in one layer

To create an insulated loggia, the parapet and walls are duplicated with masonry made of foam blocks 70–100 millimeters thick - this material has excellent thermal insulation properties and frost resistance, so some believe that there is no need to additionally insulate the walls and parapet lined with foam blocks from the inside. In fact, masonry of this thickness can freeze.

InMyRoom tip: add either extruded polystyrene foam panels or stone wool slabs to the insulation cake.

Mistake 6: neglecting vapor barrier

It is especially dangerous if you use mineral wool as insulation - without vapor barrier material it will become damp and ruin the walls and floor on the balcony, and neighbors may find condensation on the ceiling of their loggia. Inside an outdoor building room connected without a vapor barrier, condensation will certainly appear instantly.

InMyRoom tip: even if you only use polystyrene or other foam materials for insulation, nothing will stop you from adding a thin layer to them vapor barrier film. For mineral wool, such an additive is an absolute must-have!

Mistake 7: Overusing sealant without protection

Seams with bubbling foam are a perfectionist's nightmare. Aesthetically unattractive, they also threaten to spoil the climate in the apartment: the fact is that the foam of polyurethane sealants does not tolerate direct sunlight and moisture. And without proper protection, it quickly collapses, opening previously sealed gaps and cracks to drafts and street noise.

InMyRoom tip: carefully treat the “foamed” seams - cut off excess sealant, sand the material with a fine sandpaper and cover with putty or acrylate paint (it is better to use both options). If you don’t have putty or paint on hand, take special mounting tape - but keep in mind that paint will not adhere well to such seams.

Mistake 8: Improper floor design

Do not try to make the floor perfectly flat using a thick sand-concrete screed, which will subsequently be covered with a solid layer of tile adhesive and then ceramic cladding. It is dangerous to overload the ceiling. It’s better to insulate the floor using ultra-light materials (we’ll immediately agree that in this example it’s not we're talking about about the underfloor heating system).

InMyRoom tip: There are many recipes for insulating a loggia floor, but they all essentially boil down to using soft insulation directly on top of concrete slabs (you can use penoplex or mineral wool). Then it is recommended to put a second layer of insulation - and be sure to apply waterproofing (lay hydroglass insulation with an overlap of more than 15 centimeters). You can do it on top thin tie– and many craftsmen simply lay plywood if there is no significant slope on the balcony: the plywood is thin, light, smooth, and on top of it, in a warm and moisture-protected loggia, you can lay both carpet and laminate. Error 10: inattention to detail

This error occurs normally in absolutely everyone. But the most common punctures can be eliminated in the bud:

  • when glazing, plan and discuss the height of the handles, as well as the material, thickness and method of installation of the window sill board (if you decide to add a window sill to the frames);
  • figure out whether a mosquito net is needed and how it will be attached;
  • the gaps between the parapet and the floor slab that do not reach the ceiling or the glazing plane of the wall will need to be filled and completed. Determine what materials and tools will be needed - and carry out the work before insulation begins.

InMyRoom tip: If the insulation pie on the walls turns out to be quite thick, take care of additional profile extenders so that the wall does not protrude far from under the glazing.
