The design of the insulation of the loggia. Balcony insulation (100 photos): step by step instructions, tips and tricks from the masters. How to insulate a balcony with your own hands step by step photo

The notorious housing problem has been troubling us since the time when Adam and Eve were expelled from paradise. “What does paradise and balconies have to do with it?” the reader will ask. And besides, the balcony is a constructive component of our home. And the solution to the question: the better to insulate a balcony or loggia , may, in the end, bring either heavenly pleasure, or a headache due to the money, time and effort spent. After all, a properly selected insulation will turn your balcony (loggia) into additional cozy square meters, expand the space of the apartment and reduce the energy consumption of this area to preserve heat in the winter.

First, consider what types of heaters exist for balconies and loggias. Then we compare them, highlight the advantages and disadvantages, after which you can determine which insulation is best for your case.

Common types of insulation for balconies and loggias

Mineral wool

Mineral wool is widely used in the insulation of balconies and loggias due to the ease of installation and relative cheapness.

Mineral wool (basalt wool, wool made from natural fibers (linen) with a polyester content (up to 15%)) is a solid, modern type of sound and heat insulation used in the insulation of roofs, walls, ceilings, balconies and facades. For roofing, roll-type cotton wool with a density of 25-35 kg / m3 is more often used. But for the facade, it is better to choose a denser insulation up to 70-90 kg per meter, which will ensure minimal shrinkage of vertical surfaces.

The mineral wool or basalt insulator used in the insulation of loggias or balconies has shown excellent results. It can also be used as protection against moisture by laying a hydrobarrier. The thickness is chosen according to the temperature indicators of a particular region, but usually not more than 100 mm. Fasten mineral wool under the finishing layer (plastic, drywall) using slats or counter-battens.

One of the disadvantages of this insulation is the wetting of the material. Only cotton wool made from natural linen provides vapor permeability and stable operation when partially wet.

Depending on the manufacturer, cutting and specifications may vary.

Expanded polystyrene, extruded

Polyfoam - universal insulation for balconies and loggias

Expanded polystyrene extruded (polystyrene) is a heat-insulating material with a homogeneous structure and closed cells that is widely used. Almost does not absorb moisture (up to 0.1% per 1 meter per day) and does not react strongly to ultraviolet radiation. Styrofoam has differences in density and is mainly used in the insulation of technical rooms.

The material for the insulation of the balcony should be chosen as a heat insulator with an optimal flammability class, and better - with non-combustible additives in general. Moreover, the market offers all kinds of types and classes of insulators.

Scope and some characteristics of expanded polystyrene brand Extraplex 50 mm:

How to insulate a loggia or balcony? Choosing the right brand is simple, the main thing is to consider the criteria by which the material is selected. If you have a small balcony, materials on which you can apply a decorative layer are suitable. For example, plaster type "bark beetle". Expanded polystyrene is perfect for this, but you should remember about the "dew point" and use only high-quality adhesive for plates.

The downside of expanded polystyrene is the release of the harmful substance styrene when heated above 40 degrees Celsius. Therefore, it is best to insulate the balcony from the outside with such material.

Expanded polystyrene can also be mounted on mounting foam. Recently, this method of fastening is often used. The foam, expanding, does not leave gaps, well filling all the cracks. And when installing a warm floor, you can lay polystyrene foam under the heating element by gluing it directly to the balcony floor.

Advice: on the balcony, it is better to make a coating or other waterproofing of the walls, ceiling and all junctions (windows, doors), since usually balconies are most susceptible to leaks. You can also use a hydrobarrier as a moisture insulator.

Penofol

Penofol is a modern insulation used for insulation, including balconies and loggias

Penofol is a thin modern insulation, which is also suitable for warming balconies or loggias. More than three modifications are produced.

Space saving is the number two priority in all installation and finishing work. Here, penofol comes to the fore.

Type "A" - they are used both in combined insulation of external walls from the inside (polystyrene foam plus penofol), and in an independent version, using a material 10 mm thick. The product, consisting of polyethylene foam, with a reflective layer on one side, will serve you well for many years.

Type "B"- foil material with two reflective surfaces is more used for additional floor insulation, both under the screed in rooms, and as a substrate on balconies and loggias under a warm floor. The high operational and reflective qualities of such an insulator have proven themselves well.

Type "C"- self-adhesive product, with one-sided reflective layer, easy to mount on walls and ceilings. The requirements for surfaces for such insulation are minimal: cleanliness (dust removal) and surface evenness (can be glued to concrete). Do not forget to carefully prime the places of insulation.

Type "ALP" It has both a reflective layer and a protective polyethylene membrane.

If, for example, you want to bring out additional pipes for floor heating in the loggia, the ALP type of penofol is laid as a reflective layer under the pipes and screed. The protective film of such material does not react with the wet solution during the work on pouring the screed. Then, having made reinforcement with a mesh (usually brand BP-1) and placing beacons or guides, pour the solution. Do not forget about aluminum tape for gluing seams and junctions. It is better to wrap the edges of the penofol on the walls, by about 80 mm.

Important: pipes that are laid as a heating element must be under pressure of 5-7 atmospheres when pouring. Such a measure will prevent the base from breaking in the future and relieve stress in the thickness of the material when heated (there is room for expansion). Installing a pressure gauge in the system will make it possible to monitor the indicators and tell you if there are any leaks in the system.

And it is best to glue the screens for additional batteries on the balcony with type “C” penofol, with a reflective layer inward to the battery.

Briefly about the properties of penofol:

What is the best way to insulate a balcony?

Before deciding how to insulate a balcony or loggia, you need to understand which side to use the insulation and where. At the same time, glazing the balcony is a mandatory step, otherwise, what's the point of insulating if everything is ventilated.

The balcony can be insulated:

• bottom (floor);
• top (ceiling);
• inside (walls);
• outside (also walls).

Insulation of the floor of a balcony or loggia

The better the material for warming the balcony, the better the microclimate of the enclosed space will be preserved. In light of the latest trends, insulating the floor on the balcony is highly recommended. This will give energy-saving heat savings from 20 to 40%, depending on the type of insulation. The cost will pay off, especially if you plan to convert the balcony into an extra room.

Warming methods:

• using insulating materials;
• underfloor heating system.

Insulation materials:

Mineral wool

The advantage is low cost, ease of installation. The disadvantage is that over time it becomes caked and loses its insulating qualities. With an illiterate calculation of the heat-insulating layer (this is a completely separate topic of conversation), you can not achieve the desired effect.

Styrofoam

Good, comfortable, cheap material. The disadvantage is that mice eat it. It will be necessary to take care of excellent tightness.

Expanded clay

Lightweight, cheap, eternal heat insulator, but cooler.

Penofol

Moderately costly. Combines the qualities of mineral wool and polystyrene. It can be laid on an imperfectly flat surface. According to experts - one of the best heat-insulating materials for warming balconies and loggias.

Penoplex

Also moderately costly, a good heat insulator, but requires a very flat surface.

Underfloor heating system

There are three options:

water floor

Connected to the central heating system. If you do not have individual heating, then this option is not suitable due to the lack of permissive legislative acts.

Electric

1. Cable.
2. Cable with reinforcing mesh.

Electric floors are effective together with self-leveling floors and tiles.

Film (infrared)

Installed without major repairs. A technically simple solution.

Attention: the film floor cannot be used under tiles and screed. It is possible under linoleum or laminate.

Insulation of the ceiling of a balcony or loggia

It makes sense to insulate the ceiling on the balcony if your balcony is located on the top floor.

To insulate the ceiling on the balcony, the following materials are used:

• drywall;
• Styrofoam;
• penofol;
• penoplex (foamed polystyrene foam).

Do not forget that when insulating the ceiling, a decrease in the ceiling space is inevitable.

If you do not want to do capital insulation of the ceiling, then you can get by with decorated foam tiles. In this case, there will be two advantages: an elegant ceiling with a small layer of insulation.

Insulation of the walls of a balcony or loggia

Before insulating the walls of the balcony, it is necessary to close up all holes and cracks. Neglecting such a trifle as a gap in cold windy weather will result in loss of heat and lack of comfort.

Balcony insulation materials are the same as for floor insulation. It:

• expanded polystyrene;
• penoplex;
• penofol;
• mineral wool.

You can add stuff like isover.This is a more modern mineral wool based on fiberglass. Available in rolls or sheets.

Another option is styrodur is a green extruded polystyrene foam.

Wall insulation can be carried out from the inside and outside. In the event that it is necessary to save the usable space of the balcony, it is recommended to insulate the outside, and inside - only finishing work.

As in any other case, the choice of insulation from the outside has its advantages and disadvantages:

It is not easy to choose which insulation suits you, how to specifically isolate a particular room. The best way of warming will be combined.

Example: it is better to insulate the ceiling of the loggia and all walls with basalt wool mats, the floor with polystyrene foam, and use penofol as an additional noise-absorbing and heat-reflecting layer.

When choosing a material, remember that the flammability class and environmental friendliness are perhaps the most important criteria.

So, taking into account the plans hatched for the further use of a balcony or loggia, time and financial possibilities, taking into account the recommendations received, you can now make a reasonable balanced decision on choosing a heater for your balcony or loggia.

Those who have an apartment in an apartment building understand the need to insulate the balcony. This question remains relevant at any time, since the basic, "draft" option, which is installed by default in most homes, does not have any advantages. In the summer on such balconies it is unbearably hot, in the winter it is very cold. Accordingly, the microclimate in adjacent rooms is also disturbed. In this case, the owners come to the conclusion about the need for insulation and insulation. So how to properly insulate a balcony from the inside and what is necessary for such work?

It all depends on the location of the apartment in which it is planned to insulate the balcony. As a rule, the owner himself can answer this question. But if the apartment was purchased recently, and the owner has not encountered such issues, you need to pay attention to the following nuances:

1. The apartment is located on the top floor. In the summer, on the upper floors, as a result of heating the roof, a greenhouse effect occurs, which leads to overheating of the premises. In particular, the balcony heats up the most.
2. The balcony faces either the sunny side or the shady one. When you are on the sunny side there will be a strong overheating, when you are on the shady side on the balcony in winter it will be very cold.
3. The balcony is of poor quality, the main slabs are cracked and do not provide reliable protection from the weather.

It should be noted that the thermal insulation of the balcony implies the performance of indirect, but no less useful functions - when installing plates increased noise and moisture insulation.

The conclusion is as follows: the balcony must be insulated as soon as possible. There are no disadvantages with proper installation, and the advantages are obvious.

Preparing the balcony before warming

Before you insulate the balcony from the inside with your own hands, first of all, it is necessary to carry out preparatory work. The entire surface, from the floors to the ceiling, is thoroughly cleaned of large and small debris, the floor covering (if any) is dismantled and all decorative elements (shelves, cabinets, fixtures, etc.) are removed.

The next step is to check the integrity of the structure. Very often, balcony slabs have a large number of chips and cracks. If any are found, it is necessary to remove the deformed areas (if the damage is extensive), after which, using cement mortar close all cracks and holes. The result is a rough floor and walls that are ready for insulation work.

Some craftsmen carry out finishing plastering of surfaces before carrying out insulation work. This procedure should be performed in cases where the surfaces are uneven and interfere with the correct laying of the insulating material.

Balcony insulation: detailed instructions

Is the balcony prepared? In this case, you can begin to answer the question of how to properly insulate the balcony. First of all, it is necessary to install high-quality double-glazed windows. It is recommended to use dual designs, ideally with argon fill. If the reader lives in a region where average winter temperatures drop to -30 degrees, then you need to think about installing three-chamber double-glazed windows.

Balcony insulation technology can be divided into the following stages:

• After installation of plastic bags all cracks and gaps must be eliminated. To do this, you can use any sealant or mounting foam. In the event that the cracks and gaps are large, improvised materials are used to reduce their size.
• Waterproofing the inner surface of the balcony. Various materials can be used - bituminous mastics, roofing felt, liquid penetrating materials (like Penetron), etc.
• Insulation is attached. We will discuss this point in more detail below.
• Placed on the heater vapor barrier material.
• The interior surface is being finished.
• Floors are installed (depending on the preferences of the master).

Balcony insulation with Penoplex

Penoplex belongs to the group of expanded polystyrenes, has excellent indicators of moisture resistance and resistance to mechanical deformation. The side surface of the plates can be both smooth and ribbed, for better fixation of the layers with each other.

The methods of fastening the material depend on what kind of finishing will be done. If lining or drywall will be used as finishing materials, then you can use mushroom-shaped plastic dowels. If, after the walls are insulated, plaster will be applied, then it is recommended to use adhesive materials for additional fixation.

Penoplex insulation technology is as follows:

• On the prepared primed surface, Penoplex plates are attached, which are interconnected butt-to-butt or according to the “thorn-to-groove” system.
• Each plate of insulating material is fixed to the wall with special dowels.
• The joints of the sheets must be glued with adhesive tape, while the joints with other structures - with mounting foam without toluene impurities.
• Next come the vapor barrier layer, crate and finish.

Important: It is possible to insulate the balcony with Penoplex with the preliminary installation of the crate. Then the material is laid between its bars.

Penoplex is considered one of the best materials for thermal insulation work. First of all, this is due to its durability. If this indicator is not important, you can use ordinary foam.

Insulation with foam

This material is known to all the inhabitants. As a rule, insulating foam is produced in the form of sheets, the thickness of which varies between 5-15 cm. To insulate the balcony, it is enough to use plates with a thickness of 10 cm.

The process of warming a balcony or loggia is as follows:

• The surface is treated with a primer with deep penetration;
• With the help of special glue, foam sheets are attached to the treated surface;
• For additional fixation, plastic dowels can be used;
• The joints between the sheets are glued with foam. After drying, the seams on top are additionally glued with adhesive tape;
• A reinforced fiberglass mesh is mounted on the surface of the installed insulation using a special adhesive solution;
• After installing the mesh, you can carry out finishing work.

The option with pre-installation of the crate is also common, as we considered earlier, speaking of Penoplex.

Warming with lining

Of course, wooden planks cannot be high-quality insulation. Lining as a heater can only be used if the balcony is a well-heated room. Otherwise, before installing the lining, it is necessary to install a base insulation.

The balcony is insulated with clapboard as follows:

• A wooden crate is installed on which the lining will be attached. Usually the crate is installed horizontally.
• In between, foam sheets are installed by analogy with the previous version of insulation.
• After installing the foam, you can install a lining, which is attached to the surface of the walls on a wooden crate.

Note that such work should be carried out only if the balcony structure is strong enough. That is why before its installation it is necessary to carry out calculations on the strength of the surface.

Warming with mineral wool

Mineral wool is often used as a balcony insulation because of its structural features. Benefits of mineral wool obvious - high-quality thermal protection, low cost and vapor permeability. But there are also disadvantages. So, mineral wool, if installed incorrectly, loses about 40% of its properties, and sheets of material are brittle.

We will provide our reader with the option of mineral wool insulation:

• On a previously waterproofed surface, on which there is already a crate, mineral wool slabs are glued and additionally fixed with dowels.
• The material is tightly and carefully fixed in the gaps between the wooden beams of the crate - mineral wool is fragile.
• The last step is to install a vapor barrier, after which you can begin to lay the finishing material.

Note that it is very easy to insulate a balcony with your own hands - this does not require special knowledge and skills. If you have detailed instructions that allow you to properly carry out glazing, you can do it yourself - it all depends on your desire.

Balcony insulation video

We suggest you watch videos on how to properly insulate a balcony. The video uses penoplex as a heater and shows the entire sequence of work with this material.

If the apartment or house has a balcony, then you should definitely use it, as this is an additional, and sometimes just a necessary area. If you approach the issue with imagination and think through all the nuances, you can get a small, but very cozy room. In order for the balcony to serve as a room, it must be insulated. How to insulate the balcony inside is decided by each owner independently, taking into account their financial capabilities and urgent needs. But a few words should be said about the nuances of the process and the materials used to insulate the balcony. It is necessary to choose these materials very carefully and pay attention to all the characteristics.

It is necessary to begin the development of any balcony with an objective assessment of its condition. If the apartment is located in a new house, recently handed over to residents, then you need to pay attention to the material from which the balcony structure is made. Also in new houses, it is necessary to pay attention to what the balcony of the neighbors is trimmed with. Often in such houses, neighbors try to adhere to a single style.

We make masonry from foam blocks

But if the balcony is located in a far from new apartment and has always been used as an open space, then work will have to start with balcony reinforcements. Strengthening is understood as the reconstruction of the concrete platform of the balcony, and the strengthening of the metal handrail. Also, such an event as strengthening the lower part of the upper balcony can be included in this process, this should also be taken into account. After resolving all these issues and choosing the material for the exterior cladding of the loggia (balcony), you can proceed to the interior decoration. To simplify this stage, you can lay out a wall of bricks or foam blocks up to half of the balcony, directly to the double-glazed windows. This will save on insulation.

Tip: If all stages of insulation are carried out at the same time, then it is better to immediately install double-glazed windows in the windows, since one glass gives heat loss in cold weather by 70% more.

Preparing for insulation

To start warming the balcony inside with any materials, you need to prepare. Having chosen the material for insulation, it is necessary to create a special wooden crate under it, on which it will then be attached. The exception is rolled materials that can be mounted under the crate. This frame is made of beams with a cross section of about 4-5 cm. The transverse and perpendicular beams must be fastened so that squares of 50 by 50 cm are obtained. Also, the crate can be made of a metal profile, but this material is somewhat more expensive than wooden bars. The main advantages of a metal frame are the ease of construction and ease of use.

Note: When calculating the necessary insulation for a balcony inside, it is necessary to take into account not only the dimensions of the walls, but the floor and ceiling, since these two positions also need to be insulated.

Material selection

A heater is laid in the crate on the inside of the balcony, which can be:

Styrofoam insulation is one of the most common ways of thermal insulation of balconies and loggias.

Styrofoam. The cheapest of these materials is plain white foam, 5 cm thick. If the room is insulated in cold latitudes, then you can take a thicker foam, it can reach a thickness of up to 10 cm. It can be easily cut into the required number of parts, and you can not strengthen anything additionally, but immediately lay the crates in the cells for finishing materials. The material is absolutely safe both when working with it and during subsequent use. The insulation is completely odorless, does not emit toxic substances, and styrene fumes in small quantities do not affect people's health. The installation of the material occurs without the formation of dust.

Warming with mineral wool

mineral wool. Mineral wool is a little more expensive, but its noise insulation performance is much higher, so if you need to get rid of extraneous sounds, it is better to use it. This material is completely natural and completely fireproof. The combustion temperature of mineral wool starts from a thousand degrees. The inconvenience of laying mineral wool briquettes lies in the obligatory observance of safety measures. The material in its composition contains small particles of glass, which cause itching of the skin. It is necessary to carry out installation in protected special clothing, goggles and a respirator.

Expanded clay. The material is an environmentally friendly insulation. The word "expanded clay" is translated from Greek as "burnt clay". The material is often used for floor and ceiling insulation. It is not entirely profitable for them to insulate the walls, since in addition they need to prepare a metal mesh as a support.

The installation of high-quality double-glazed windows plays a big role in the insulation of a balcony or loggia. - you will find the answer here.

Penofol. This material is one of the heat-insulating means that has a reflective effect. Represents a layer from the made foam self-extinguishing polyethylene with the closed air pores. Coated with high quality aluminum, 14 microns thick and 99.4% pure on one or both sides. Penofol is a universal material with steam, hydro, wind, and soundproof properties. The material has the appearance of a thin, flexible, light and environmentally friendly structure. It can be used as an additional vapor barrier, it is very convenient for them to work, as it is sold in rolls and can be easily cut even with ordinary scissors. This material protects the room from moisture from the outside and saves the room from condensation.

Penoplex. It is a new material specially developed for warming rooms. The material is very easy to install due to its low weight, so its use on the balcony is now relevant. It is produced in the form of rectangular plates of different thicknesses, which are easily cut with a clerical knife. It is also possible to produce "sandwich panels" by pouring. Insulation with a rough surface makes it easy to attach and glue them to other materials.

Izolon

Izolon. It is also a versatile material in terms of use. Confirmed safety in use as a heater and vapor barrier element. Excellent soundproofing characteristics.

The degree of thermal conductivity is compared:

• with 15 cm brickwork
• with 4.5 cm wood
• with 4.5 cm mineral wool
• with 1.2cm styrofoam

Reduces noise by at least 18 dB.

These are the basic materials for creating an insulating layer, which are now easy to find in any hardware store. We hope you now have more information about how to insulate a balcony from the inside and then we'll see how to do it.

How to insulate

One of the best methods for laying insulation is layered laying:

• Surface waterproofing first.
• The next layer is the selected insulating material, which is also fastened with appropriate fasteners. It can be nails, self-tapping screws, plastic fasteners with wide caps.
• Then a vapor barrier is laid, which is fastened with a construction stapler.
• At the final stage, a finishing material is attached to the crate using special fastening materials.

Styrofoam sheets are installed in the crate, and the joints are smeared with mounting foam

You should get a layer with a thickness of approximately 60 - 70 mm, this is the distance from the outer layer to the finishing one. Depending on climatic conditions, this size may vary. It must be understood that any layer of insulation requires financial costs and labor, so it is better to immediately make a balcony in good conscience and not try to save on trifles.

In a situation with floor insulation on the balcony the sequence is also the same. If it is decided to fill the floor with concrete, then first expanded clay is laid and a solution is distributed on top of it. The concrete solution must be carefully distributed with a special rule and try to make the surface as even as possible. Then ceramic tiles or other finishing materials can be laid on such a surface. Under the final finish, you can lay rolled heated floors, and this will give additional warming to the room.

A video instruction for self-assembly of a plasterboard ceiling is available at this address

If the option of a wooden floor is chosen, then first the guide logs are laid, between which the insulation is laid. Then a finishing board or chipboard is laid on the logs. Laying chipboard is necessary if further installation of laminate or linoleum is carried out. It is also worth noting that under the laminate it is necessary to lay special substrate, which will provide additional thermal insulation. When the walls and floors are finished, skirting boards are installed that hide the joints of the finish.

In the complex of works on the insulation of the balcony, attention must be paid to the ceiling. The process of insulation is carried out in the same way as the walls and floor. The task will be complicated by the moment when the balcony or loggia is on the top floor and there is no ceiling. In this case, you need to take into account the additional costs for the installation of the ceiling and roof.

When working on the insulation of the balcony, one should not fuss and rush, this can lead to an unreasonably large consumption of material. If you approach the matter with attention and carry out constant calculations, then you can get a full-fledged additional room for little money.

How to insulate a balcony from the inside video

We invite you to watch a video on the topic of our article “Insulation for a balcony inside - choose materials”, which shows in detail the entire process of insulating a balcony using penoplex and penofol.

How to properly insulate a balcony from the inside with my own hands - I had to ask myself such a question when the idea came to my mind to turn our ownerless balcony into a home one. As it turned out, sewing in a room that is a nursery is not at all comfortable for me. I wanted solitude and silence in order to be completely focused on work, and I also interfered with children's study and recreation.

In this article I will talk about how we carried out repairs to turn our cold and ventilated loggia into a living room, or rather into my office, and at what price it cost us. And I will also give valuable advice that will help you avoid mistakes and save your nerves and money)

How to insulate a balcony from the inside with your own hands

What I had to face and what our loggia looked like before insulation

When I told my friends about my idea, at first everyone laughed at me. They began to talk about how little space there was, and they were frightened by the cold of the unheated room - after all, our loggia was essentially an outdoor space. In order for you to imagine what I had to face, I am attaching a plan of the balcony. I had to turn three and a half squares of usable area into a full-fledged study, where my two sewing machines with a table, a cutting table, and an ironing board could fit.

The first window with a balcony door and access to the kitchen. This wall is the main one - it is already warm, so you can not sheathe it. Subsequently, we refused to cover it with plaster, since the brick itself looks quite interesting in the interior. We only cleaned its surface with a sandpaper from dirt.

The second window is located on the wall of the loggia; it required a complete replacement and touched the stained-glass windows. The photo was taken after the installation of a new double-glazed window.

Balcony window replacement

The first thing my story with a balcony began with was the replacement of an existing double-glazed window. When we moved into our new building, we saw that on the loggia (unlike other rooms) the developer installed the windows in one layer of glass. Of course, it was a summer version, they let the cold through with might and main. There was no talk of replacing the double-glazed window, because I also wanted to change the shape of the frame, make an opening sash of other sizes. I don’t know how the project of our house was made, but the architect obviously did not try for the convenience of the residents. Therefore, first of all, I found a company that made a solid two-chamber window according to our sizes. As stated by the window makers, such a window provides 25% more heat retention in the room than the one that was from the developer.

When ordering a new window, there was one small fad that significantly increased the amount of our expenses - this is lamination. That is, from the street side, all the window frames of our house are dark burgundy, wood-like. Therefore, we also had to fit in with the overall picture and make a window in the overall color scheme. For lamination, companies involved in the manufacture of windows ask from 20% of the total cost.

The price for a window measuring 2580 * 1520 cm with a burgundy frame, with installation and delivery, amounted to 20,700 rubles. And we profitably sold the dismantled old window to the Avito website.

Important (!)- if you are going to insulate the balcony and increase the ceiling after installing the window, then tell the window makers about it. They will put extensions on the top of the window so that later your extended ceiling does not close the shutters and you can hang curtains.

Loggia heating, which method to choose

The loggia usually has walls in one layer of bricks, the worst option is a corrugated balcony. Therefore, in order to feel comfortable in this room during the cold season, a heater is needed.

There are two options for how to make the loggia warm. The first is to open the balcony door so that it heats up at the expense of the adjoining room. The second is to install electric "warm" floors or buy oil radiators.

I will say right away from our experience that one heater was not enough for us, and we decided to install a warm floor. Despite the fact that the walls of our loggia were insulated, it was cold from the neighbors above and below - after all, their balconies remained uninsulated.

The choice of material for warming the loggia (balcony)

At the very beginning, my husband was advised to do the insulation of the balcony with his own hands, in general, he is handy with me - he can put a laminate and glue the tiles. But in the case of the balcony, I did not have time to wait until he finds free time, here I needed the work of a professional, since correcting mistakes would cost more. So we found a master who is engaged in this business and watched his work from the side. I found him through Avito, which I first of all paid attention to - real photos and accommodation in our area (so that he has the opportunity to go for lunch, I don’t spend a lot of time).

I wanted not just to panel the balcony, but to make walls that could later be wallpapered, so we chose drywall for the interior cladding. Finding a good specialist who would work with drywall and mount the wiring (after all, I still needed sockets and lighting) turned out to be not an easy task. But I was lucky and found a good specialist who promised me to bring my idea to life! On his advice, after taking all the measurements, we purchased for the insulation of our loggia:

• drywall - for walls and ceilings
• plywood - for the floor
• technonicol rocklite - for flooring
• technonikol technoplex - for walls and ceilings
• isolar - reflective metallized substrate
• bars

The most important thing on this list is insulation. It is due to him that you get a full-fledged living room. We have chosen two types of insulation:

The first type, for floor insulation, is technonicol rocklite. It is a rectangular slab, pressed from basalt fibers, in the common people it is called mineral wool. There is no need to be afraid that it can have an adverse effect on the air in the room (many write about harmful fumes, etc.), on the contrary, due to the ability to pass moisture, and not retain it, it is widely used for warming damp rooms, where there is a possibility of mold and fungus . According to the TechnoNIKOL company, its plates do not burn and do not absorb moisture, therefore today they are recognized as the best heaters on the market. In order to cover the floors of the loggia with an area of ​​3.8 m2 in two layers, we needed 1 pack of technonicol rocklite, in which there were 12 slabs.

The second insulation we used is technoplex technoplex for interior wall cladding. As I mentioned above, the developer built our loggia in one layer of brick, due to this, it blew from every corner. In addition, uncomfortable stained-glass windows were installed in the loggia on the sides of the window, which gave the house a businesslike look from the outside, and served as a source of constant drafts and moisture for the residents inside. This type of insulation is made of nanographite, due to which it has an unsightly gray color. Although in terms of weight and appearance, it reminded me more of polystyrene, but despite its lightness, it has excellent thermal insulation characteristics. After our balcony ceased to resemble a bamboo hut, I began to think about how to use these magic tiles to make soundproofing from neighbors in the living room)

The third type of insulation- it rather goes as an addition to the first two, it metallized substrate isolon or isolar. We all know that a shiny surface reflects well. It is this ability of the metallized surface of the substrate that allows you to redirect heat into the room, as if reflecting it and preventing it from escaping outside.

As a result, I can say that all the heaters coped with their tasks with a bang, they really keep warm, like a thermos. But at the same time, they allow excess moisture to pass through, preventing the formation of mold.

How to insulate a balcony with your own hands step by step photo

1. We cleared the balcony of everything superfluous. Before the arrival of the master, we cleaned our balcony of rubbish and debris, a window had already been installed and heating radiators had been installed.

2. Patching the "holes" of stained-glass windows with the help of technonicol technoplex insulation boards. This did not affect the exterior of the house, but for us the problem of eternal drafts was solved. The slabs were laid in two layers, all the cracks were filled with mounting foam.

Cutting the plates after taking measurements is carried out using a jigsaw and a hacksaw for metal.

3. Bringing electrical wiring to the balcony. In my workshop, it was planned to install three outlets for sewing machines and a laptop, the wires were pulled from the nearest outlet from the kitchen.

4. Floor insulation with beams and technonicol rocklite insulation (mineral wool). According to the reviews of our master, he most of all likes to work with this type of insulation. Since when placed between the bars, it expands on its own and does not leave any gaps, which means it does not require the use of mounting foam.

Although basalt wool and glass wool are two different things, I still played it safe and diligently closed the door to the balcony while he laid the floors. And then for an hour I vacuumed all the walls. Of course, our master laughed for a long time when he saw me walking in a medical mask and gloves. For me, any mention of glass wool is a fear from childhood, when we ran around a construction site and accidentally touched glass wool, any of us got a burn, after which it itched and burned for a long time.

A frame or so-called formwork for the future floor and walls is first assembled from wooden bars. Between themselves, the rails are fastened with metal corners using dowels and a screwdriver.

If the frame is laid on concrete, then first, holes are drilled on the concrete floor at the attachment points using an impact drill. Then, dowels are inserted into the wooden logs, applied to the attachment points and the screws are driven in with a hammer.

Mineral wool mats can be laid immediately on a concrete screed, in a wooden frame between the joists. It does not shrink at all, therefore it is used even on surfaces with high traffic.

To give the floor additional thermal insulation properties - on top of the first layer of basalt wool insulation, you can build a second frame of the crate and lay another layer of rocklite technonicol in the same way. In this case, wooden bars are fastened with a screwdriver to self-tapping screws.

Next, an isolar layer is used - this is a metallized substrate that reflects heat and protects against moisture, and is widely used to create a warm balcony (loggia). After laying all the layers of building materials, we reached the same floor level as the room without thresholds and steps.

Important (!)- the metallized substrate is laid with the reflecting surface upwards.

5. Ceiling insulation with technoplex insulation. In our ceiling, two wires for ceiling lights were installed. Therefore, before proceeding with the installation of the ceiling, electrical wiring was brought out under the wooden beams. I really like this method - it looks neat, without unnecessary wires. Electricians from have a lot to learn from the Bashkir masters)

6. Wall insulation with technoplex technoplex insulation.

The main difference between nanographite and basalt wool insulation is that it is not elastic. Therefore, when installing it into the crate, gaps remain, which then need to be filled with mounting foam.

After all the joints have been processed, a metallized isolar substrate is applied over the insulation. It is attached to the crate using a stapler and a special adhesive tape (connecting tape) - isospan.

After sheathing the entire surface with a metallized substrate, drywall sheets are attached to the wooden crate using self-tapping screws and a screwdriver from above.

Do-it-yourself plastering of a balcony (loggia)

After the balcony was completely sheathed with drywall sheets, including the ceiling, we had to plaster the walls. You can’t glue wallpaper on bare drywall, because its top layer consists of paper and can come off when wet. Additional surface treatment of sheets includes a primer and putty.

At this stage of work, our master left us, since he was only engaged in insulation, and the work of a plasterer as a painter was not part of his duties. We were faced with a choice - either to find a new employee, or to pick up a spatula ourselves. A significant role in the choice was played by the amount that the plasterers asked for - professionals for processing our small area.

Therefore, my friends, for the first time in my life I picked up a spatula and plastered my balcony myself (I posted a photo with the result a little lower). But I will say right away that I liked plastering, as it turned out, working with a gypsum mixture is not at all difficult, and if you are not particularly picky about your walls, feel free to pick up a trowel and master a new type of activity! Later (as experienced craftsmen scared me) after drying, nothing fell off, and the loggia became even warmer - after all, I responsibly covered all the cracks and joints.

So, to plaster a balcony lined with drywall sheets, I needed:

• gypsum plaster "Volma layer"
• deep penetration drywall primer
• serpyanka tape for joints
• putty knife
• container for diluting plaster
• drill with nozzle mixer for mixing the solution
• oilcloth to protect the surface from dirt (floor and brick wall)

1. First, I went over the walls with a primer to improve the adhesion to the top coat. Waited 40 minutes for it to dry completely.

2. I sealed all the joints on the drywall with tape - sickle. It forms a strong bond with the binder mixture, which is especially important at seams and corners.

3. Prepare the solution. I first diluted everything according to the instructions, and then mixed the plaster with water by eye. For the second time, you already know exactly what consistency the solution should be. I applied two coats of plaster. It took me four hours to get to work. I concluded that you can cope and learn how to work with a spatula even if you are a beginner. What happened to me you can judge from the photo. The color of the Volma layer plaster after drying becomes not white, but gray, so the ceiling had to be whitewashed with water-based paint.

How much money did it take us to insulate the balcony with our own hands

• Two-chamber window with lamination (assembly, installation) – 20.700
• Nails, switches, sockets, cable, polyurethane foam, sealant - 4.800
• Insulation, bars, drywall, plywood - 11.600
• Window sills, braids, laminate, wallpaper, lamps – 4.000
• Master's work - 10.000

Total for our loggia with an area of ​​3.43 sq.m. it took us 51.100 rubles. The amount of expenses depends on the size of the area to be insulated and what materials will be used for this. As you understand, insulating a balcony in Khrushchev will cost much less than insulating a large balcony with panoramic windows.

1. Mentally prepare for the fact that it will be necessary to allocate temporary space for building materials. All these heaters, drywall sheets and wooden blocks are impressive in size and occupied our entire entrance hall of 13 sq.m. It was especially hard for me with small children, who cannot be kept in place and I had to constantly make sure that they did not stumble and carry dirt around the apartment.

2. Separately, it is worth mentioning garbage and dust. Despite the fact that all the dirty work was carried out on the loggia, the builder still had to walk between the balcony and the hallway for materials and tools. Therefore, the entire floor was strewn with shavings and debris. Every time after his work, I had to carry out wet cleaning in the house with a rag and a vacuum cleaner. This is an important reason - why I quickly wanted to finish with the insulation of the loggia.

3. The amount that we were initially agreed on for the purchase of building materials was approximate. That is, in the process, you still had to buy something.

4. One person cannot do all the work for sure. There are two ways out: to find a company doing turnkey repairs, the prices of which start from 50 thousand rubles. Or, as we did, we separately looked for a master for each option. As a result, for the whole process of warming our loggia, we needed: specialists in the manufacture and installation of windows, a plumber, a master in warming and cladding balconies, a plasterer-painter. It turned out cheaper than ordering from the organization, but I also had to spend time searching.

5. Keep in mind, if you still decide to insulate the balcony with your own hands without the help of a specialist, then you should have the tool necessary for the job at hand. These are a jigsaw and files, a drill, a hammer, a screwdriver, a sealant gun, a puncher, a construction ruler with a level, a drywall assembly construction knife, a construction stapler.

6. Do not throw away checks, they may come in handy when repairs are completed and unused building materials remain. Within 14 days from the date of purchase, you can return them to the store and get your money back, provided that the package remains unopened.

7. It is better to make purchases in large chain stores. For example, Leroy Merlin gives buyers the opportunity to return an unused item for repair within 100 days after the purchase. I did not have any difficulty in returning the extra rolls of wallpaper, glue and cornices that did not fit in height.

Conclusion

I hope our experience helped you on how to properly insulate a balcony from the inside with your own hands with a step-by-step photo. Many complain that after warming the loggia still remains cold. We specifically measured the temperature on the balcony, with minus outside. She remained as warm and comfortable as in the apartment.

Work on the insulation of the balcony is of course difficult and dirty. But how much joy I now have in my own workshop. I have my own little corner where I can work quietly without disturbing my loved ones, create in my personal space. So if you have an idea to make yourself an office, but there is no place in the apartment, pay attention to the balcony or loggia. Good luck everyone, bye!

The balcony is a part of the building that needs insulation more than others, because not all residents use it only as a warehouse. Increasingly, people are beginning to equip their balconies for additional space, for example, a personal office. For these and not only reasons, it is necessary to produce competent insulation of the structure from the inside.

In this article, we will consider three methods using different materials.

Stages of balcony insulation

Insulation of the balcony from the inside is performed in the following sequence:

No. 1. Balcony insulation with polystyrene foam: sequence of work

If you chose expanded polystyrene as a heater, then the sequence of work is as follows:

No. 2. Insulation of the balcony with penoplex (video)

Penoplex is actively used in the insulation of rooms. You can fix it to the surface using bituminous mastics, mounting foam or mushroom dowels. Consider the option of mounting on mounting foam.

Foam mounting

So. Waterproofing done. Mounting foam is applied to the insulation plate around the perimeter. It's enough. After applying, wait a couple of seconds and fix the plate on the insulated surface. The next plate is laid end-to-end to the first. After two days, you can fix the plates with additional dowels. Then the whole process is repeated in the same order as described above. Do the finishing to your liking. You can sew up the insulation boards with plastic panels, they look very original.

Additionally, we fix the plates with dowels

Advice. If the balcony is intended only for storing essential items on it, then it is enough to insulate the walls in one layer. If you need to insulate more thoroughly, then it is better to lay the insulation in two layers.

The process of warming the balcony is completed. As you can see, it does not represent anything complicated. If you are just planning to do this work, then our article will help you. If you have already done, then share your methods with readers in the comments.

No. 3. Balcony insulation with mineral wool: technology features

Warming of balconies with mineral wool is carried out under the constructed crate. A lining is attached over the frame - wooden or plastic panels with special grooves.

A well-known fact is the building recommendation to carry out insulation from the outside of the building. However, in the insulation of balconies and loggias, it is often not possible to place the insulation material outside. The internal placement of the insulation layer requires certain calculations, adherence to technology and the correct selection of materials so that in the future the work performed does not lead to wetting of the walls, corners and ceiling inside the remote structure.

Balcony insulation with mineral wool

What materials can be used to insulate a balcony and? What finish will allow you to reliably protect the insulation from the interior space and create an aesthetic appearance of the interior walls?

In modern technologies for insulating open hinged structures (balconies), four types of material are used as internal insulation: polystyrene foam, foam plastic, penofol and mineral wool. Consider the technological features of installation and types of cotton wool insulation used for thermal insulation of balconies.

Types of mineral wool

Depending on the raw materials used in the production, there are three main types of mineral wool: glass, stone and slag. All three materials are suitable for insulation work.

Mineral wool is a soft material that does not have rigid dimensions. It is supplied in the form of rolls (before laying they are unwound into a track) or soft mats. Sometimes one side of the insulation is covered with aluminum foil to enhance the thermal insulation properties.

Important! During installation, the foil should be located on the side of the room. The internal heat of the room will be reflected from the foil surface back into the living space.

The thickness of the mineral wool layer determines the quality of insulation and varies in size from 20 to 200 mm.

Mineral wool installation technology

Any type of mineral wool is mounted under the frame, located between the outer wall (ceiling, roof) and the frame supports. Wooden sticks or metal profiles can be used as supports, depending on which cladding will be used in the future.

Lathing from metal profiles

When using lining for finishing wall cladding, the frame-lathing is constructed of wood. Wooden sticks with a cross section of 150 - 250 cm 2 are installed, while you can save a little the interior space of the balcony by installing sticks of a rectangular rather than square section (30 × 50 cm 2, 30 × 70 cm 2).

Wooden crate

All racks and horizontal laths of the crate are installed under the level. Fastening of vertical racks to the concrete surface of the ceiling and floor is carried out with anchor bolts. Horizontal ones are attached to the vertical supports. If the future cladding is made of plastic lining, horizontal slats are attached at three levels: knee, thigh, shoulder.

Insulation laying

Note: before installing the insulation, the walls are treated with an antifungal primer.

For internal insulation with mineral wool, it is mandatory to install a vapor barrier. By itself, the cotton material is breathable, it easily passes gaseous substances (air, steam).

Insulation must be protected from getting wet

Given that during internal insulation, the point of condensation is shifted into the insulation, it is necessary to limit the ingress of steam or air from their living quarters into the building wool. For this purpose, a vapor barrier film is laid between the mineral wool and the finish.

Interior decoration

Purpose of interior decoration:

• Close the heat insulator material from the living space.
• Create an aesthetic interior wall covering of a room or insulated loggia.

There are various materials for interior decoration of balconies (drywall, wood, plastic, plaster). With a previously constructed crate frame, the finishing is done by hanging various types of panels: plywood, MDF, lining made of wood or plastic.

Clapboard made of plastic under a tree

Finishing with clapboard is done by lining the walls with wooden (or plastic) carload panels, which have special grooves around the perimeter for ease of installation and fastening density. At the same time, plastic lining is often a cheaper imitator of a wooden coating laid on the inner walls of a balcony (or loggia). It is characterized by less strength and rigidity.

Plastic panels are easy to install

Wooden wagon panels are reliable, environmentally friendly, have sufficient rigidity for flooring. Plastic clapboard can sheathe the ceiling of the loggia, the floor is covered with wood, as for the walls - both types of wagon cover (plastic and wood) can be used here.

Finishing with wooden clapboard

After finishing, the inner surface is treated with a composition that protects the wood from moisture and from destruction.
