How to insulate a balcony with wooden windows. How to insulate a balcony with your own hands: step by step photos, instructions, choice of materials How to avoid mistakes when insulating a balcony

Independent connection and insulation of the loggia is a whole story with additional construction, sophisticated 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 the loggia a full part of the apartment and not regret it!

Mistake 1: reorganization and redevelopment without permission

Even if you don’t want to demolish the wall between the apartment and the loggia, but only want to insulate the space outside the window, it’s better to notify the BTI representative of your intentions so that you don’t have problems later, for example, with the sale of an apartment if there are inconsistencies in the housing technical passport.

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

Mistake 2: transferring 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, be aware that it is not allowed to bring pipes for the radiator and the battery itself beyond the outer wall of the building. The heat loss on the loggia is too high, the pipes, if not properly insulated, can freeze, accidents are possible; for the heat supply of recently non-residential meters, one would have to pay a tangible amount after an individual recalculation. One way or another, batteries are not transferred to the loggia - remember this at the design stage of an insulated balcony.

InMyRoom Tip: an electric underfloor heating system will help you or oil radiator– it can be attached to the wall in the same way as a conventional battery.

Mistake 3: installing frameless glazing

Frameless sashes look great - when closed, this smooth surface, sometimes not broken even by the edges. In addition, the sashes are conveniently assembled into an accordion, without occupying the space of the loggia. However, this solution is not suitable for an insulated balcony: single glazing and gaps between the canvases will not be able to protect from the cold. In addition, dirt and dust quickly accumulate on them, fingerprints remain and a mosquito net is not attached.

InMyRoom Tip: take a closer look at latest developments– e.g. thermally insulated lift/slide windows. But the best choice for glazing warm balcony there are PVC double-glazed windows with good old hinged doors. In fact, they do not take up much space - they can only be opened for ventilation, and plowed open twice a year to clean the glass from the outside.

Error 4: remote glazing on brackets

In an effort to increase the area, or rather, the volume of the attached loggia, the owners of the apartments build a frame for glazing with an extension of several tens of centimeters. A wide visor appears along the upper perimeter, on which snow constantly accumulates, and in the off-season it rains loudly. Most importantly, 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 has completely open balconies (or they should, in fact, be so) - it is worth parting with the idea of ​​\u200b\u200battaching or even just glazing. And ennoble the loggia with green plants.

Mistake 5: insulation in one layer

To create an insulated loggia, the parapet and walls are duplicated with foam block masonry 70-100 millimeters thick - this material has excellent thermal insulation properties and frost resistance, so some people think that it is not necessary to additionally insulate the walls and parapet lined with foam blocks from the inside. In fact, masonry of this thickness can freeze through.

InMyRoom Tip: add either an extruded polystyrene foam panel or rock wool slabs to the insulation pie.

Mistake 6: neglecting the vapor barrier

It is especially dangerous if you use mineral wool as a heater - without a vapor barrier material, it will dampen and ruin the walls and floor on the balcony, and neighbors may find condensation on the ceiling of their loggia. Inside an outdoor building without vapor barrier, of course, condensate appears instantly.

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

Mistake 7: Sealant abuse without protection

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

InMyRoom Tip: carefully process the “foamed” seams - cut off excess sealant, sand the material with fine sandpaper and cover with putty or acrylate paint (it is better to use both). If there is no putty or paint at hand, take a special mounting tape - but keep in mind that paint will not adhere well to such seams.

Mistake 8: Incorrect floor design

Do not try to make the floor perfectly even with a thick concrete screed, which will subsequently be covered with a solid layer of tile adhesive, and then ceramic cladding. Overloading the floor is dangerous. It is better to insulate the floor using ultra-light materials (we will immediately agree that in this example we are not talking about a floor heating system).

InMyRoom Tip: there are many recipes for a floor insulation pie on the loggia, but all of them, in fact, come down to using soft insulation directly on top of concrete slabs (you can take penoplex or mineral wool). Then it is recommended to put a second layer of insulation - and be sure to apply waterproofing (lay hydrostekloizol with an overlap of more than 15 centimeters). You can make a thin screed on top - and many craftsmen simply lay plywood if there is no significant slope on the balcony: plywood is thin, light, even, and both carpet and laminate can be laid on top of it in a warm and moisture-proof loggia. Mistake 10: inattention to trifles

This error is normal for 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 installation method of the window sill (if you decide to add a window sill to the frames);
• figure out if and how a mosquito net will be attached;
• gaps between the parapet and the floor slab that are not brought up to the ceiling or the plane of the wall glazing will need to be laid and completed. Determine what materials and tools will be needed - and carry out the work before the start of insulation.

InMyRoom Tip: if the insulation cake on the walls is thick enough, take care of additional profile expanders - so that the wall does not protrude far from under the glazing.

Balcony operation all year round will increase the useful area of ​​​​the apartment. Creating a comfortable microclimate is possible if you take into account the rules and recommendations of specialists for warming the balcony with their own hands. In our article, we will consider repairs using the example of a loggia of the following dimensions: 7.5 m in length, 1.16 in width and 2.9 in height. Step by step instructions and photos in the process. It took 2 weeks to repair, the budget was 40 thousand rubles, the year of construction was 2013.

Required Tool

• Screwdriver and electric drill;
• Construction stapler, level;
• Scissors, knife;
• Marker, laser tape measure;
• Hammer;
• Putty knife;
• Gas-burner;
• Special gun for glue or mounting foam;
• Containers for mixing components;
• Adhesive tape (painting and reinforced);
• Rags, sponges, etc.;
• Nozzles for a drill, with which you can stir building mixtures.

Materials (what to buy)

• Structures for glazing;
• Material for organizing a waterproofing layer (polyethylene foam);
• Insulation (mineral wool 70 mm thick);
• Wooden logs for leveling the floor and creating a solid foundation (50x50);
• Plywood sheets (10 mm);
• Glue, metal tape;
• Tiles for wall cladding in two shades;
• Laminate (thickness 12 mm).

Instructions for warming on a living example

Consider a simple repair option that most apartment owners resort to:

1. Balcony preparation before repair

On the eve of glazing, you need to carefully check the space and eliminate chips, cracks and gaps.

Depending on the size of the defect, polyurethane mastic, polyurethane foam, sealants are used. To organize a convenient seal, use a special gun designed to apply mounting foam.

The space is insulated with double-glazed windows made of PVC profile.

Glazing the loggia, or replacing old windows with new double-glazed windows is an obligatory stage of work to protect the space from heat loss.

Other materials for glazing are also used: wood, aluminum and metal-plastic. Elements of window frames must be treated with paint and antiseptics. Wooden structure the windows are leaky, have a low level of thermal insulation and an inconvenient opening mechanism. Aluminum windows are a durable option, characterized by comfort and reliability, but the level of heat loss is quite high.

It is better to give preference to window PVC frames, which also contain aluminum, but the inner formwork is not made of metal.

PVC windows are resistant to moisture and sudden changes in temperature. Such frames are easy to use, sealed and have a low level of thermal conductivity.

Masking cables in the wall for connecting the air conditioner.

2. Raising the floor level and thermal insulation

Floor waterproofing with penofol.

Most often, the materials at the base of the floor and walls are concrete and brick, which strongly absorb moisture and vapors. In order for the heat insulator to retain its properties, a waterproofing layer should be organized. Instead of penofol for waterproofing, you can choose roofing material or special impregnation. Penofol is laid with an overlap, the sheets are connected to each other using a gas burner.

Creation of a frame from rails (50x50).

Floor lathing for the subsequent laying of mineral wool.

For the construction of the crate, use wooden logs. The frame elements are fixed to each other with self-tapping screws using a screwdriver. The step of the rails directly depends on the material of the thermal insulation.

Usually the distance between the slats is 50 cm, however, for laying a soft heat insulator, the pitch of the frame elements should be reduced.

In order to exclude cold bridges in the structure, it is necessary to carefully organize the thermal insulation around the perimeter. Mineral wool is laid between the elements of the mounted frame. We fill the joints with scraps of a heat insulator and mounting foam.

Mineral wool laid in the cells of the crate on the floor.

During the work, a mistake was made - due to the different dimensions of the heat insulator (70 mm) and the height of the bars (50 mm), spacers had to be made.

Raising the floor to the level of the threshold - 20 cm.

The device of plywood sheets on the frame of the crate.

When laying plywood 10 mm sagged, so it is better to choose stronger sheets, such as 20 mm chipboard or OSB.

3. Wall insulation and window sill installation

We begin the construction of a frame to create a window sill from metal elements. This frame will allow you to insulate the parapet of gas blocks.

We do laying of electricians for lamps and other devices in advance.

We fill the metal frame with insulation, after which we sheathe the GKLV structure.

Proper insulation of the parapet on the advice of experts:

• Impregnation with special hydrophobic solutions;
• Fixing penofol with construction stapler, aluminum tape, or glue;
• Filling joints;
• Installation of the second layer of thermal insulation;
• Vapor barrier. A special membrane is suitable for organizing the layer.

Then we protect the other walls of the room from the loss of the body. For creating robust design glazing the loggia, insulating the parapet and the floor is not enough. Basically, a balcony parapet is created from a material with good strength and thermal insulation (foam blocks, gas blocks), however, such a fence does not protect the insulation from moisture.

Mineral wool was also chosen for thermal insulation of other walls.

In addition to mineral wool, other types of insulation will also fit in its place: extruded polystyrene foam (penoplex), foil polyethylene (penofol), polystyrene or polyurethane foam (PPU). The basis of all these heat insulators are polymers, which are treated with foamed compounds.

The insulated parapet is sheathed with GKLV.

Facing the base of GKLV with ceramic tiles.

Evenness of laying tiles is ensured with the help of special elements - crosses.

Alternative finishes are: PVC panels, wooden lining, wallpaper, block house.

In this example, the ceiling surface was not insulated. On the one hand, the apartment is located on an intermediate floor (11 out of 19) and there is no direct threat of precipitation, however, heat loss will occur through the floor slab, even if the neighbors from above have a well-insulated floor.

If we are talking about the insulation of the loggia of the upper floor, in this case, the ceiling slab can be protected by installing a roof. The visor is built with a slope for rainwater and snow to drain.

4. Installation and connection of sockets

We mount a socket with a light control function.

To install the socket in the wall, you need to punch a hole.

5. Finishing the room

We cover the floor with laminate and the walls with tiles. Flush docking as a result of the work failed.

To compensate for deflection thin plywood, choose a laminate with a thickness of 12 mm.

The shortcomings of the repair in a real example are the lack of a finishing coating.

A small element of ceramic tiles is missing.

There was also not enough tiles.

In this corner with flaws in the finish, a closet is planned, which should hide most visible defects.

In order to avoid a shortage of material, it is necessary to think over everything in as much detail as possible on the eve of work, drawing up a diagram according to the actual dimensions of the room. It is better to purchase material with some margin.

We decorate the window sill with ceramic tiles.

Installation of plinth on the loggia.

Threshold tiling.

When raising the floor to the level of the threshold, it is better to use one material in the finish, so the surfaces will be more harmoniously combined with each other.

During the repair process, a gap formed between the window sill and the glazing structure, to eliminate which it is necessary to use special internal corners.

Pictured is a sample outer corner purchased by mistake.

The result of masking the gap with the outer corner.

The room after laying tiles, laminate and creating a black stretch ceiling with five spotlights.

In the future, a closet will be mounted in this part of the balcony.

The first association that arises with us at the word balcony is a cold small space outside the window, where we take out everything that seems to be unnecessary, but it’s a pity to throw it away. This is not smart. More recently, the balcony was invented as an additional room for the apartment, for drying clothes and storing vegetables. But in last years the situation has changed dramatically, and now the balcony is becoming part of the interior of the entire apartment, and can perform several useful features both summer and winter. "But how is this possible?" - you say. Very simple. Nowadays, balconies are insulated, sheathed, energy-saving windows are installed, and even heated.

Consider the better to insulate the balcony of an ordinary apartment

There are two options for insulating balconies: outside and inside. Both of these methods are fundamentally different from each other. If in the first case the balcony is insulated without affecting the interior space of the already small balcony, then in the second, its usable area is reduced by at least 30-40 cm. For large balconies, this is not noticeable, but for loggias with small dimensions, this technique insulation is not suitable. "So what's the deal! - you say, - let's insulate all the balconies from the outside. The idea, of course, is good, but there is one “but” in it.

What is the best way to insulate a balcony? What methods and types of materials for insulation of balconies exist in general, and how to properly perform insulation. Our experts will try to answer these questions.

It is possible to insulate a balcony from the outside with your own hands only if it is located no further than the second floor. For work at a higher height, you need to resort to the help of professionals, which will cost a pretty penny. Therefore, it is cheaper, after all, to insulate the balcony with inside. Moreover, a lot of special materials are sold for this.

Materials that are suitable for insulating balconies inside:

• Styrofoam;
• Penoplex;
• Penofol;
• Mineral wool;
• Expanded clay;
• Izolon;
• Polyurethane foam.

Each of the materials has its pros and cons, but they are all great for warming the balcony and loggia from the inside.

To learn about the characteristics of other materials, as well as the stages of balcony insulation, you will learn from our article: https://homeli.ru/komnaty/balkon/uteplenie-balkona.

The better to insulate the balcony inside: finishing methods

There are many ways to insulate a balcony. When choosing your option, be guided by personal plans. Proceed from what functions you want to give your additional living space in the future. Modern technologies now make it possible to install energy-intensive windows, insulate facades and walls with such materials that the cold will not penetrate into the room at all, and the heat will not be able to go outside.

The better to insulate the balcony inside, if you do overhaul? Based on your financial capabilities. Of the budget materials, the most popular for insulating a balcony is polystyrene foam. It is lightweight, fully meets the requirements of insulation and does not deteriorate for a long time.

The quality of insulation, for the most part, is not affected by the material with which you plan to insulate balcony structure, but the method of its warming. The larger part of the structure you insulate, the better the thermal insulation will be, and the balcony space will be warmer in winter. If heating is additionally equipped in it, then such a balcony can be used all year round without feeling the cold outside the door.

What methods can you apply when insulating a balcony from the inside:

• Insulate walls;
• Sheathe the floor with insulation;
• Lay insulation on the ceiling;
• Line the entire perimeter of the balcony with insulation;
• Add floor heating to a fully insulated balcony.

In addition, when performing work, you can add additional methods of insulation as a foil sheet gasket, or a polyethylene film wind barrier.

How to lay insulation for a balcony indoors

After we have decided on the material for wall insulation, and the method of doing the work, we need to draw ourselves a plan for the next steps. It should consist of construction stages and periods for completing tasks. Once again, evaluate the possibilities of your balcony. If you do not already have energy-saving windows, then now is the time to install them. You are doing a major overhaul of the cladding, and it will be difficult to return to it later, and installing plastic windows will require strengthening the positions that support them.

Insulation for a balcony inside the space must be prepared in advance. Try to get the right amount consumable. This is not difficult to do, you only need to carefully calculate the area of ​​\u200b\u200bthe insulated planes.

Then, step by step, according to your own plan and studying the feedback of specialists, move forward. Immediately consider how you will decorate the walls of your balcony. The method of laying the insulating material during further cladding of the balcony with clapboard or plastic differs from the insulation of the balcony without further cladding.

Step-by-step instructions for warming a balcony:

1. If your windows are already installed, then we start by sealing cracks, cracks and damage. wood paneling check for rotten boards and fungus. If they are, then take steps to eliminate them. If there are no plastic windows, then you need to install them.
2. In the event that you will later sheathe the balcony with clapboard (which is done very often), then you need to start arranging the crate.
3. Consider electrical wiring. Do the wiring in advance so that you do not have to spoil the repair later.
4. We begin the warming process. Lay insulation in the space between the battens of the crate, attaching it in accordance with the type of material.
5. Seal the gaps between the insulation, if it is solid.
6. Seal the joints with mounting tape.
7. For greater thermal insulation, lay a layer of penofol on top.
8. Level surfaces.
9. Line the walls with finishing material.

When carrying out work on the balcony, one rule should be taken into account - to repair the balcony, choose the lightest finishing materials. The balcony is a special design, and it should not be overloaded.

Practice shows that it is best to insulate balconies from the inside with penoplex and penofol. It is better not to use mineral wool for this. Although she is soft and comfortable, she does not like dampness. And temperature drops on the balcony are inevitable, therefore, condensate as well.

What is the best way to insulate a balcony from the inside if there is not much money? Use foam. It is not expensive, but quite practical material. A properly insulated balcony will serve you for a long time and reliably.

Styrofoam, 4-5 cm thick will be enough to insulate the walls of the balcony. As an adhesive, use liquid nails, or special glue. Do not use for gluing heavy mixtures. In order for the repair to progress in stages, and the finishing materials do not interfere with each other, perform the work in a certain sequence.

Stages of work on the insulation of the balcony:

• Install plastic windows;
• It is best to start the insulation of the balcony from the ceiling;
• After finishing it, go to the floor.
• Lastly, the walls are insulated.

If you do everything right, then in the end your repair will converge into one harmonious idea.

Thermal insulation of the balcony with penofol (video)

When the repair work on the balcony is completed, you can begin to equip it. If this part is on the sunny side, you should definitely hang curtains. You will find options and solutions in our following material: https://homeli.ru/dekor/shtory/shtory-na-balkon-idei-i-foto.

What your balcony will look like after insulation is up to you. Apply maximum skill, patience and time, and you will equip yourself with a beautiful room where it will not be hot in summer and cold in winter.

We choose modern materials that are suitable for warming the loggia from the inside

To create a comfortable functional room in the loggia, it is necessary to carry out work on its high-quality insulation. On the market today are the most different materials, therefore, it is possible to insulate the loggia with mineral wool, polystyrene foam, polystyrene foam and other types of heaters. The choice of insulation depends on many factors. It is very good if there is an opportunity to consult on this matter with experts.

Mineral wool

Mineral wool insulation is the traditional and most common option.

This material can provide a sufficiently high level of thermal insulation and sound insulation.

At the same time, it is recommended to use mineral wool for insulation only if there is no load on the insulation. In addition, the insulation material must be protected as best as possible from moisture and condensation on it.

Mineral wool insulation works are carried out in the following sequence:

1. First, waterproofing of all surfaces insulated from the inside is performed. This stage is preliminary. To create a high-quality waterproofing layer before insulating with mineral wool from the inside, it is best to use special insulating impregnations. Bituminous and polyurethane mastic, special paints and varnishes. In addition, rolled polyethylene materials are often used as an insulator (sold at any hardware store). What kind of insulator will be used does not really matter.
2. Then you need to perform the crate device. The step of installing wooden bars should be about 1 cm less than the width of the mineral wool sheets. In addition, it is necessary to select the bars in such a way that their thickness is slightly larger than the thickness of the heat-insulating material slab. The elements of the crate can be fastened to the draft surfaces with dowels and self-tapping screws.
3. To install mineral wool slabs, you need to select and dilute a suitable adhesive composition (which one does not matter). It is applied to the surface of the slab from the inside, after which it is placed in the cell formed by the crate. The slabs must be adjusted in such a way that they are slightly larger in size than the dimensions of the cell. This will avoid unnecessary voids.
4. As soon as the adhesive composition dries, it is recommended to additionally fix the heat-insulating material with your own hands using fungal dowels.
5. Surface cladding can be done with any suitable materials. For this, any type of finish is suitable, which will not create a large load - plastic panels, plywood sheets, lining ...
6. Finally, surfaces are cleaned and decorative works. Work in this case can be done with any finish.

Good results and reviews are given by ISOVER material.

Styrofoam

Warming your loggia inside with polystyrene foam gives quite good results. This material is produced by mixing polystyrene and special foaming components. The mixture is heated, subjected to high pressure, then foamed and carbon dioxide is added.

For insulation of the loggia with polystyrene foam, plates with a thickness of 45-50 mm are perfect.

1. They are fastened with dowels, double-sided tape and glue (which type of fastening to choose depends on the material of the walls). When insulating the loggia with polystyrene foam from the inside, it is best to place the material plates in a checkerboard pattern so that they do not move under their own weight during operation.
2. To prevent the occurrence of cold bridges, seams, gaps and docking zones must be filled with your own hands construction foam(when insulating with expanded polystyrene and polystyrene, the problem of cold bridges is especially relevant).
3. As soon as polyurethane foam dry, you need to cut off its excess with your own hands.
4. To provide additional insulation, which is required when insulating with polystyrene foam and foam plastic, it is imperative to lay a layer of special polyethylene foam 5-8 mm thick. In this case, the foil layer should be located inside the loggia. Such an approach will allow you to form a high-quality vapor barrier layer with your own hands and ensure heat reflection. The seams must be glued with construction tape with your own hands.
5. A wooden crate can be attached to the heat-insulating layer (for this, it is better to use small-sized bars that have been pre-treated with antiseptic compounds). In addition, instead of lathing, often from the inside, the loggia is finished with plasterboard sheets.
6. On wooden crate or drywall sheets, any finishing finishing materials can be applied with your own hands.

You can do without crates and use a mesh for reinforcement, under fine finish.

Penoplex and penofol

Very often penoplex and penofol for insulation are used in the same insulation system.

One of the best stuff.

These are high-quality insulating materials that have a lot of positive working and technical characteristics. Many experts recommend using them specifically for warming loggias from the inside. The use of such a heater for the loggia will allow you to create a comfortable environment indoors and maintain an optimal microclimate on the coldest days.

Penofol for the loggia.

Insulation works using these materials are carried out in the following sequence:

1. First, do-it-yourself preparation of all insulated surfaces: floor, ceiling, walls, parapet. The old finishing material is completely removed, all traces and debris are removed. After that, you need to carefully check the integrity of the structures from the inside so that they do not have cracks, holes and other defects through which cold air can penetrate into the room. It is important that the loggia is completely sealed from all sides.
2. Then, the installation of vertical logs is carried out. You need to fasten the material with certain step, the size of which will depend on the thickness of the insulation used.
3. Further, penofol is fastened directly to the lags. To do this, you can use any suitable adhesive compositions suitable for indoor use. During the installation of the initial layer of penofol, it is required to direct the foil outward.
4. After that, the installation of penoplex is carried out (the best option for a loggia is a material with a thickness of 20 - 25 mm). Laying slabs from the inside of the loggia can be done independently - there is nothing complicated in this process.
5. Finally, you need to glue another layer of penofol. In this case, the material must be positioned so that the foil layer is directed inward. As a result, we will get a kind of pie in which the main heat-insulating material (foam) will be protected by foam on both sides.
6. All joints that arose during the installation work from the inside of the loggia must be glued with construction adhesive tape.

What thermal insulation material to choose for warming the loggia?

You need to understand that do-it-yourself loggia insulation work can be done from the inside and outside. Of course, it is much easier to make insulation inside the loggia. For this, various thermal insulation materials. Their choice will depend on the design features, operating conditions, the nuances of the installation work, so in each case, the choice of insulation should be given Special attention.

It will not always be justified to buy the most expensive heater on the market.

For example, if the loggia has high-quality glazing, high-quality construction, and no defects are observed, then the simplest materials can be used. In addition, the choice of insulation for the loggia will depend on whether heating is planned.

The better to insulate the balcony inside: what materials to choose

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.

Where to begin

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 far from new apartment and it 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 outer cladding loggias (balconies), 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 roll materials, which can be mounted under the crate. This frame is made of bars with a cross section of about 4-5 cm. The transverse and perpendicular bars must be fixed so that squares of 50 by 50 cm are obtained. Also, the crate can be made of metal profile, but this material is somewhat more expensive than wooden bars. Key Benefits metal frame is the ease of construction and ease of use.

Note: When calculating necessary insulation for a balcony inside, you need 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 evaporation in small quantities does 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 like 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.

After warming, you will need to move on to the interior decoration of the balcony. For these purposes, plastic panels are well suited. Read more about them and their differences in this article.

The installation of high-quality double-glazed windows plays a big role in the insulation of a balcony or loggia. Which window profile to choose? - 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 versatile material that has steam, hydro, wind, and soundproof properties. The material has the appearance of a thin, flexible, light and environmentally friendly structure. As an additional vapor barrier, foil foam can be used, 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.
• On final stage, to the crate, with the help of special fastening materials, finishing material is attached

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. concrete mortar it is necessary to carefully distribute the special rule and try to make the surface as even as possible. Then on such a surface you can lay ceramic tiles or other finishing materials. Under the final finish, you can lay rolled heated floors, and this will give additional warming to the room.

Learn more about how to raise the floor on the balcony with your own hands and what materials you can use to do it.

Read about how to choose an electric underfloor heating. Features of different models.

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 insulate a balcony with your own hands: from a refrigerator to a warm island

To begin with, it is worth saying that there are two ways to insulate a balcony - from the inside and outside. External insulation, of course, is more convenient - precious centimeters of area are not “eaten up”, and the cladding of the balcony facade becomes more pleasant. But this is a laborious process that requires the involvement of a construction team and industrial climbers. Therefore, in the article we will focus on how to properly insulate a balcony in an apartment from the inside - this can be done independently.

For insulation inside the balcony, first of all, it is necessary to carry out preparatory work. They include several important steps:

• How to start warming a loggia or balcony? Free up space from all unnecessary. It is best if the balcony is completely empty: it is much easier to work this way. Also, get rid of the old finish in advance.
• Seal all the cracks - a lot of heat escapes through them. For small gaps, a weather-resistant sealant is suitable, fill larger gaps with mounting foam - it will not only fill the voids, but also serve as an additional heat insulator.
• To make it easier for you to carry out work on insulation, it is important to even out cracks and irregularities on the walls and ceiling with cement mortar.
• If you plan to place light bulbs or lighting fixtures on the balcony, you should take care of the wiring in advance. To hide unpresentable cables, place them in plastic boxes.
• Before starting work, cover the opening between the balcony and the adjoining room with a film so that construction dust and other pollutants did not get into the apartment.

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

How to insulate a balcony: what materials are better 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 with our own hands).

Most often, mineral wool, polystyrene foam, polystyrene, 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:

What is the best insulation for a balcony? The answer to this question depends on your preferences and financial capabilities. You can read more about the characteristics of heaters, as well as about the insulation of an apartment as a whole, in our blog.

The balcony is the most vulnerable room in the apartment, which often suffers from severe frost and wind. And if earlier it often served as a kind of pantry, storing all the necessary (and often even unnecessary) things, now many people are turning the loggia into a full-fledged room.

The only difficulty that residents face is that it is almost impossible to be on the balcony in winter - frost and strong wind create a beautiful picture outside the window, but a cold atmosphere on the loggia. However, today it is possible to prevent this problem. A huge number of thermal insulation materials make it easy and quick to insulate the balcony with your own hands.

Preparation for warming the balcony

In any repair or construction process, everything begins with the preparation of surfaces and territory. Therefore, before how to insulate a balcony with your own hands, you will have to get rid of all the trash that is there. By the way, things that you still plan to leave afterwards also need to be moved to another room.

After the balcony is completely cleared of unnecessary things, you need to fully inspect the room. First, it is important to understand which parts of the loggia require more thorough insulation. In addition, you need to pay attention to cracks and chips that allow cold air to pass through.

Important! Some balconies have a rather small area. And the thermal insulation material takes up the space of the room. In this case, it is better to immediately determine the so-called "cold" and "warm" zones of the loggia and insulate only those that are more susceptible to frost and wind.

Right now it is desirable to get rid of significant defects on the surfaces. Large gaps can be sealed with putty or foam.

At the same stage, you should decide on the type of insulation for the balcony and stock up on all necessary tools. We will talk about thermal insulation materials a little later. And now let's look at what tools you need in order to insulate the balcony.

Balcony insulation tools

Insulating a balcony with your own hands is a fairly simple and understandable process. The main thing is to understand the sequence of work and stock up on the necessary tools. These include the following basic materials:

1. insulation in required quantity(the calculation takes place in accordance with the number of layers and the area of ​​​​the balcony).
2. Facing material for external finishing.
3. Mounting foam.
4. waterproofing materials.
5. adhesive mixtures.
6. Wooden or metal beams(for the frame).
7. Dowels, screws, nails of different sizes.
8. Metallized adhesive tape for sealing seams.

In some specific cases, you may also need:

• drill;
• perforator;
• scissors;
• hammer;
• building level;
• rollers;
• spatulas, etc.

Everything here will depend on finishing loggias.

Balcony insulation restrictions

Since the process of insulating a balcony is highly complex, in order to carry it out, you will need to obtain permission from some authorities. Indeed, some methods can greatly increase the load on the building itself. As a rule, you should contact the government agencies involved in housing redevelopment for confirmation.

Also, do not forget that the warming of the loggia is a rather noisy process. Therefore, it is better to warn your neighbors about upcoming repairs. This will help avoid many misunderstandings in the future.

However, even after obtaining permission, you cannot dispose of the balcony as you wish. There are some prohibitions that apply to the insulation of the loggia. So, for example, you can't:

1. Remove load-bearing walls and partitions.
2. Install water heating on the balcony.
3. Turn the balcony into a bathroom (due to the lack of necessary pipes in the loggia). Organizing a kitchen on the balcony is a more realistic solution. However, it requires additional permissions.
4. Change the height of the ceiling on the balcony.
5. Violate the original architectural appearance of the building.

The better to insulate a balcony: the main materials for insulation

To date, there are a huge number of options than to insulate a balcony from the inside. The choice of one or another option may depend on many factors:

1. How much are you willing to spend on insulation?
2. climate.
3. Building type.
4. your personal preferences.
5. Material resistance to frost, wind, moisture.

One way or another, before proceeding with the insulation of the loggia, it is important to study in detail all the popular materials. This is the only way you can choose the option that suits you best. We suggest you familiarize yourself with the most common heaters.

It is made of clay, therefore it is considered an environmentally friendly and safe material. Expanded clay is a small and light porous granules. A similar weight and structure of the material can be achieved thanks to a special clay firing technology. The raw material is first heated to about 1000 degrees, as a result of which voids are formed inside, providing heat and sound insulation. Expanded clay is used to insulate walls, floors, ceilings or even the foundation of a country house.

Mineral wool

The most common insulation for walls and floors. Outwardly, it resembles a thick canvas, which consists of many randomly intertwined molecules. The raw material for mineral wool is glass, rocks or slag. In order for the fibers to be securely connected to each other, they are impregnated with special mixtures based on oils and alcohol. Mineral wool itself is divided into several other types:

• glass wool (consists of glass, stove and limestone);
• stone wool (made from basalt rocks);
• slag wool (produced from blast-furnace slag).

Styrofoam

Perhaps the lightest thermal insulation material. It is a foamed mass, which is more than 90% filled with air. It is thanks to this technology that it is possible to achieve good result and qualitatively insulate the balcony. The popularity of polystyrene foam as a heater is also due to the large choice of material. It is divided into the following categories:

• sheet;
• polystyrene in balls;
• extruded polystyrene foam (which we will talk about a little later);
• liquid foam;
• foam formwork.

Extruded polystyrene foam

Today, many people prefer to insulate the balcony with polystyrene foam. This material is a subspecies of foam and is also characterized by low weight and good thermal insulation properties. Comparing polystyrene and expanded polystyrene, it can be noted that the materials have both common features and some differences. For example, the texture of the latter is not granular, but more even.

polyurethane foam

The basis for polyurethane foam is a subspecies of plastic, which has a foamed structure. Like some previous heaters, this material is 90% composed of a gaseous substance with which all its cells are filled. Usage various technologies helped create several types of polyurethane:

1. Elastic (in other words - foam rubber), which fills sofas and armchairs, and is also used to make washcloths, shoe linings, etc.
2. Rigid - actively used for heat and sound insulation at home.

Penofol

It is one of the most innovative heaters for the balcony. This material consists of several layers:

1. Polyethylene foam self-extinguishing.
2. Aluminum foil.

Unlike previous heaters, penofol is not able to absorb heat. Thanks to the foil, it works according to a different principle, namely, it reflects thermal radiation. The material, in turn, is divided into several types:

1. Type "A" - the foil is on one side of the insulation.
2. Type "B" - with foil on both sides.
3. Type "C" - with a special self-adhesive insert.

Balcony heaters - comparison table

As you can see, there are a lot of materials for insulating a balcony. To determine which option is right for you, we recommend comparing all of the above categories:

Ceiling insulation

If you plan to insulate the balcony with your own hands, then it is best to start from the ceiling and move further from top to bottom. Of course, if the ceiling of your loggia is the floor of your neighbors, then the process of protecting the room from frost and wind is much simpler. However, if the roof is independent, then a little effort should be made to insulate it.

For the best protection of the balcony from cold and wind, we recommend that you perform work in the following sequence:

1. Spraying or special film for sound insulation.
2. Balcony ceiling waterproofing. In this case, the most popular materials are PVC or polyester.
3. The special membrane protecting from wind. It freely passes the steam that is released from the insulation, but it helps to completely isolate the ceiling from the wind and drops that can enter the room with it.
4. Anti-condensation material that protects the insulation from the formation of water droplets.
5. Frame (metal or wood of your choice). The crate is an optional element. Insulation can be installed using special glue. The main thing is to make sure that the mixture does not contain toluene. For greater reliability, when fixing the sheets, use dowels.
6. Insulation for the ceiling of the balcony. We recommend that you use polystyrene foam, polystyrene foam or mineral wool. They provide good protection from the cold and are easy to install, which is especially important when insulating the balcony ceiling.
7. Vapor barrier for insulation. It does not let water vapor inside, due to which the thermal insulation properties of the material are significantly increased.

We warm the floor on the balcony

The initial stage of warming the floor of the balcony is the installation of waterproofing on the surface. Polyethylene or penofol will do an excellent job with this role. Be sure to hide all the joints between the sheets with adhesive tape. This way you can be sure that the balcony is protected from moisture as much as possible.

Advice: If you are using single-sided foam (type "A"), install it with the reflective layer down.

Another popular option for waterproofing the floor on the balcony is bituminous mastic. However, do not forget that such material dries for about 24 hours.

After waterproofing, you should install a frame or in another way - logs. To do this, use wood or metal. The main thing is to choose the highest quality material that can last for many years.

Advice: If you are installing wooden beams, make sure that the moisture in them does not exceed 12%. Also for that. To prevent the appearance of fungus, we recommend that you treat the beams with an antiseptic or a special primer.

The bars are laid at a distance equal to the width of one sheet of insulation. As for the height of the beams, it is usually 10-15 cm. Ordinary mounting foam is used to prevent gaps that appear between the logs and the balcony wall.

After installing the lags, you can proceed directly to the installation of insulation. Make sure that there are no even the smallest gaps between the sheets (or plates) and the frame. Otherwise, your work will not bring the desired result. In some cases, the insulation is laid in several layers (for greater protection). Then it is important that the seams between the plates are not in the same place. That is, you need to lay the material with a slight offset.

Wall insulation

In the process of insulating the floor on the balcony, it will not be superfluous to immediately take care of the walls. So, for example, making out a waterproofing layer, sheathe the entire room around the perimeter with it. This will make your future work much easier.

1. Create a frame from wooden beams. The distance between them and the width of each beam should be related to the dimensions of the insulation.
2. Install thermal insulation material. For walls, traditional options are most often chosen - mineral wool (or glass wool), polystyrene foam, polyurethane foam, penofol (or isolon). For greater reliability, we recommend combining several thermal insulation materials (for example, foam plastic and mineral wool).
3. In the presence of cracks and large seams, polyurethane foam is used. With its help, you can reliably protect the balcony from cold and wind.
4. Do not forget to install a vapor barrier on the insulation.

Important! Most often, the wall that connects the balcony and the room (living room, kitchen, etc.) is insulated with one layer. While on external walls at least two layers of insulation should be installed, or a denser heat insulator should be used.

How to insulate windows on a balcony?

If you want to insulate the balcony from the inside as efficiently as possible, in no case should not forget about the windows. After all, even the highest quality thermal insulation materials for walls, ceilings and floors will not bring any benefit if the wind breaks through the cracks in the window opening.

If all this time your balcony has not been glazed, you should pay special attention to the wall that protects it from the street. The parapet (namely, this is the name of this wall) must be strong enough to withstand the frames and double-glazed windows. In some cases, it is better to further strengthen this part of the loggia. There are two options for strengthening the parapet:

1. brick. The simplest method, which, however, is not particularly reliable and durable.
2. Reinforcement with steel bars. Use thick iron bars and cement. This method is a little more complicated than the previous one, but several times more reliable.

Before glazing the balcony, it is necessary to choose the material from which they will be made window frames. Of course, the most popular today are PVC structures. However, some modern manufacturers make wooden or aluminum frames, which are in no way inferior to plastic ones (except that they are more expensive).

Classic wooden frames practically not hermetic. Therefore, with their help it will be impossible to insulate the balcony. Therefore, they are best used in areas with a warmer climate.

As for aluminum structures, then they are able to retain heat much better than wood. In addition, they are also resistant to rust and corrosive processes. However, the most the best option(If the criterion is to consider the price-quality ratio) are plastic windows. They are not afraid of high humidity and temperature changes. In addition, such structures are distinguished by good thermal conductivity. Therefore, if you want to insulate the balcony, choose PVC windows. The most common types of structures today are:

• hinged windows;
• windows with two-chamber sash;
• extended profiles.

Advice: If you do not have the time or financial ability to update the balcony glazing, you can try to insulate the opening with special materials (mounting foam, foam rubber, etc.).

Additional methods for warming a balcony

If you live in an area with a cold climate, one heater on the balcony may not be enough. After all, even the highest quality heat insulators are sometimes not able to protect against severe frosts. Therefore, on cold winter days, additional insulation of the balcony can be arranged.

For example, install an ordinary electric heater. For greater effect, it should be placed near the wall connecting the balcony and the apartment itself.

Important! Never place a heater near windows. The condensate that will be released during the process can greatly damage the double-glazed window.

If you do not want to install additional heating devices, and it is strictly forbidden to carry out central heating on the balcony, you can install a “warm floor” system on the loggia. It will serve for decades, creating comfortable temperature even in the cold season. In addition, today many such systems are equipped with a special thermostat that helps you choose the most optimal mode.

Another option for additional insulation is air conditioning. In addition to the fact that he will heat the loggia in winter, he will also be able to cool the air in summer days. However, the use of an air conditioner has one rather important disadvantage - it will not be able to heat the floor on the balcony with high quality. Therefore, the warm floor still wins.

Advice: Installing underfloor heating is another cost item. You should not rely only on your own strength, since installing the system is a rather complicated process. It is better to entrust the work to professionals.

Protecting the room from cold air and strong winds, do not forget that on the balcony it is also important to organize good ventilation. With hermetically sealed gaps, this will be a little more difficult. Therefore, we recommend that you periodically ventilate the loggia for a more comfortable stay on it.

If you live in a cold climate, pay attention to the ventilation system of the “breather” type, which supplies purified air from the street, preheating it to the temperature you need.

Common mistakes when insulating a balcony

Organizing the insulation of the balcony on your own, you can not take into account the many important nuances. As a rule, people make fairly predictable and common mistakes, including:

How much does balcony insulation cost?

It is quite difficult to calculate in detail the cost of warming a balcony. Since this process includes many stages. Especially today, with a rather unstable exchange rate, prices for materials and works of craftsmen are constantly changing.

But in any case, you can make an approximate cost of warming the loggia. The main thing to remember is that the final amount can change in any direction (although, as a rule, it only increases in the course of work). Therefore, when allocating money from the family budget, it is better to take a little more than what is written in the estimate.

total cost internal insulation balcony consists of the following separate items of expenditure:

1. Balcony glazing. Most often it is the largest percentage of the total amount. High-quality double-glazed windows and their installation will be quite expensive. But the effect of them will be much more noticeable than when using cheap options.
2. Heater cost.
3. The price of others building materials(wood for logs, mounting foam, glue, etc.).
4. The cost of the work of professionals (if you plan to order the services of masters).
5. The cost of finishing and filling the balcony (finishing materials, furniture, etc.).

When insulating a balcony, it is better to choose only quality materials and use the services of glazing professionals you trust (regardless of the cost of their services). The only expense item that you can save on is the services of loggia insulation masters. With full glazing of the room, you can sheathe the balcony with insulation yourself. And since the work of masters is expensive, you can save from 5000 hryvnia and more.

Warming the balcony with your own hands is a rather laborious process. However, with a little getting used to, you can do all the work without resorting to the help of professionals. Thus, you will be able to save an impressive amount and at the same time make the loggia warmer and, as a result, more comfortable.

The loggia is a part of the apartment that requires high-quality insulation. If you leave it in its original state, then in winter the cold will penetrate into the rest of the premises, and this is an extra cash cost for heating. Owners who do not know how and with what to insulate the balcony on their own invite workers whose services cost a lot of money. And it’s good if hired craftsmen turn out to be professionals, because contractors with a lack of qualification often come to the call.

Show all

If we take professionals as an example, they first visually assess the condition of the balcony and take into account the year in which the apartment building was built. Then they pay attention to the frame (metal or wooden) and evaluate the dilapidation of the skin. Last but not least, experienced workers compare neighboring loggias and can offer the owner to make a design in the same style as them.

Because of the old-style balconies, all work becomes more complicated, especially if this building is not closed, but open type. In this case, the craftsmen are engaged in additional strengthening of the structure and replacing rotten parts: they cut off the rusted metal elements of the frame and reconstruct the concrete site. The upper and lower parts of the balcony are reinforced without fail.

how to insulate a balcony with your own hands

It is after the restoration of the structure that specialists are engaged in facing and internal thermal insulation premises. Often, owners prefer to equip their balconies with foam blocks and double-glazed windows. The stones are laid out at half the total height of the loggia, and the open space is closed with windows. As a result, not only an attractive appearance of the building is created, but also its strength is significantly increased. By the way, a double-glazed window will significantly warm the room.

If the owner of the apartment changes the windows to plastic ones, then it is advisable for him to purchase products with double glass, since single ones retain heat by only 30% in the cold season.



Without preparing the balcony, one cannot approach subsequent cardinal actions. Before purchasing materials for warming the loggia, inside the premises, specialists carry out the following work:



The interior arrangement of the loggia concerns not only the ceiling and walls. It is equally important to insulate the floor, for example, with penofol.



For internal insulation of almost all structures, expanded polystyrene is very widely used. Its low cost does not affect the quality. It is sold in the form of plates with a thickness of 5 cm or more. If the apartment is located in the conditions of the north, then it is better to use sheets 15 cm thick. For the installation of foam, they make a crate with the same cells. Expanded polystyrene is convenient in that it can be easily cut with an ordinary knife.

The positive aspects of this insulation are that it is odorless, does not emit harmful substances, is environmentally friendly and does not affect human health. Sheets, as a rule, are fixed on special "umbrellas" or building glue. As a savings, it is better to insulate the balcony inside it.

Mineral wool is also quite popular. Such insulation is slightly more expensive than foam plastic, but this is due to the additional sound insulation that the material has. Therefore, using mineral wool, you can not only insulate the structure with high quality, but also eliminate street noise. It is sold in the form of yellow rolls.

Insulation of the loggia Secrets of skill from Alexei Zemskov

The fire safety of this insulation is at a high level, and the absence of a specific smell makes mineral wool one of the most popular. The material begins to melt at a temperature of 1000 degrees. Under such rolls, it is also necessary to make a crate. Another plus is easy cutting. The disadvantage is due to the composition, which includes powdered glass, which sticks into the skin when working and causes itching and redness.

Penoplex is a new insulation that has appeared on the building materials market relatively recently and has already become popular. It has a low weight, due to which it is convenient to work with it. Penoplex is produced in the form of rectangular sheets, the cutting of which is possible even with a clerical knife. According to the method of attachment, it is similar to foam, which is glued or fixed with fasteners. The surface of the material is rough, so it does not slip in the hands.



Granular expanded clay is often laid on the floor. Such insulation for a balcony inside has a porous structure and consists of baked clay, so it is environmentally friendly. Builders use it to insulate floors and ceilings.

The work process is simple, it is enough to create a layer of expanded clay and spill it with liquid cement so that the granules are held together. But keep in mind that such material will take 15-20 cm of height from floor to ceiling. In addition, a thin-layer screed will have to be poured over the expanded clay, because the relief surface will not be suitable for laying, for example, the same parquet or laminate.

Another option for insulation - penofol. It is made from polyethylene foam. The material is especially suitable for water-heated floors, as it has a foil coating with a heat-reflecting effect. This insulation has 4 advantages: it does not let the wind through, retains heat, prevents the penetration of water and has vapor barrier properties. Penofol is flexible and easy to cut, and environmentally friendly substances do not harm human health. They produce insulation in the form of rolls, therefore, it is convenient to work with it. The installation process takes no more than 1 hour.

Insulation of balconies and loggias: eight mistakes of finishers

As previously mentioned, foam plastic is cheap, but nevertheless it is practical, many builders use it. What is the best way to insulate a balcony from the inside with polystyrene foam:



Wall thickness from edge interior decoration to the outside, given the foam block, should be 30 cm. This is enough to retain heat and prevent the penetration of cold into the room.

Pouring concrete, expanded clay layer and similar ways cost a lot of money. You can make a similar insulation, but at the same time save money. An option for a cheap finish made of wood and foam can be like this:



How to insulate a balcony? Choice of heater.

Specialists always start finishing from the walls and ceiling, and at the end they deal with the floor. If everything is done the other way around, then the base will be damaged, and the front surface will be scratched.

It is very difficult to calculate the final amount, because many factors affect it. First, you must first decide whether the loggia will be a living room. If yes, then you will have to spend money on double-glazed windows. Secondly, the prices for heaters change almost every day. Thirdly, you need to decide what kind of furniture the room will be furnished with. Therefore, you should not allocate a strictly fixed amount for such an event; it is better to prepare additional finance just in case in case unforeseen expenses arise.

It is also recommended to prepare an estimate in advance and find a cheaper source for selling the material, for example, not through intermediaries, but directly buy building materials at the base. If you seek help from specialists, they will take into account the following points:



Also, you may have to spend money on furniture and other interior items.

Arranging a loggia with the help of specialists will cost a large amount, which will significantly hit the wallet. But if you insulate the balcony inside with your own hands, then the final expense will be approximately 10 thousand rubles.
