In this article, we will talk about how to protect the walls of the loggia from the penetration of cold, and also give advice on what tools and materials will be useful to you for this purpose. But first I would like to dwell on those problems that will have to be overcome in the process of work.
Common Mistakes
A serious problem is created by condensate, which forms from the inside on the cold surface of the walls and ceiling. As a result, damp areas appear, which very quickly become covered with a layer of mold. This happens due to poor ventilation, improper insulation and heating systems.
When the ventilation of the room does not work correctly, the air quickly moves from the warm part of the apartment to the cold, i.e. to the loggia. There excess moisture settles on the coldest surfaces. Ordinary doors help to avoid such a negative effect, which separate rooms with different temperature conditions and, consequently, with different humidity.
Insulation systems also cause a lot of trouble. If, for example, the insulation of the walls and floor was done incorrectly, then moisture will certainly leave its marks on the problem areas of the loggia.
If you decide to save on foam, and instead sealed the seams between the plates with a putty mixture, then condensation is very likely to settle in these places with all the ensuing consequences. It is better not to make such mistakes at all, since it will be very difficult to eliminate them. Therefore, it is very important to adhere to the technology of all insulation processes.
Often the problem is a poor-quality loggia heating system. If this process occurs only through warm air from the next room, then mold will definitely form in the cold corners of the outdoor room. Therefore, it is advisable to start wall insulation with floor insulation on the loggia.
This is also important in order to comply with building codes, because the installation of water heating on balconies is prohibited. A well-equipped warm floor is sensitive to temperature changes in its various areas and automatically eliminates this imbalance.
Silence
Insulation of walls, in addition to its main purpose, has other positive effects. It becomes much quieter on the loggia, which means that the noise level is significantly reduced in the rest of the room.
After all, it is the loggia that is exposed to numerous noise influences from the outside.
Material selection
Modern market thermal insulation materials provides customers with a huge choice, which is quite difficult for a beginner to understand, so it is better to seek advice from specialists. Many of them are advised to opt for extruded polystyrene foam or, as it is called in everyday life, penoplex.
This material has excellent heat-saving properties, high strength and low hygroscopicity. In addition, it is easy to process, featuring high environmental standards and chemical neutrality.
Other types of foam are widely used as a heater, however, unlike foam, they have more modest thermal insulation characteristics. Often for and loggias use penofol and mineral wool.
Wall insulation
Insulation of the walls of the balcony consists of several stages. Let's consider each of them in detail.
It is possible to successfully insulate a wall only if the corresponding preparatory work. Do not be too lazy to spend time preparing, this will provide an excellent result.
First of all, thoroughly clean the walls of the old coating. It’s good if, before warming, you replace obsolete window structures on double-glazed windows, and also remove the old mounting foam from the frames.
For this, it is best to use a clerical knife. If there are significant mold formations on the inside of the walls, they must be eliminated. In this case, a fungicide spray will do.
Then you should carefully mark the lines for fixing the foam sheets.
Laying the insulating layer
At first, warming a loggia may seem like a rather complicated and time-consuming process. However, if you decide to try, you will quickly realize that there are no particular difficulties here. All operations are quickly mastered and do not require special construction skills.
From the balcony it will also be possible to make a comfortable and useful room. For example, equip it with an office, a workshop, a small sports area or a comfortable rest room.
Owners of city apartments often wonder how to insulate a balcony inside with their own hands. This procedure is actually quite simple. However, it is still necessary to comply with the established technologies during its implementation. First of all, of course, you will need to decide how to insulate the balcony inside with your own hands. The type of sheathing of the parapet, walls and ceiling will largely depend on the type of material chosen.
Expanded polystyrene or mineral wool?
These two materials for warming balconies and loggias are most often chosen. Expanded polystyrene is a little more expensive than mineral wool. However, at the same time, it is also the best answer to the question of how to insulate the balcony inside. The fact is that when sheathing the loggia from the side of the living quarters, the so-called is located inside the insulating "pie". Therefore, it is much better to use moisture-resistant material for insulation. Inexpensive mineral wool, unfortunately, does not differ in such properties. It absorbs moisture very quickly. Of course, you can use it. However, in this case, you will have to pay maximum attention to waterproofing. So the best answer to the question of how to insulate a balcony inside with your own hands is still polystyrene foam.
Material characteristics
When choosing sheets for balcony insulation, you should pay attention to the following factors:
density,
Expanded polystyrene sheets produced by modern manufacturers have standard sizes: 2x1, 0.5x1 or 1x1. Those who wondered how to sheathe a balcony from the inside should think about purchasing smaller sheets. It will be very inconvenient to mount too large plates in the limited space of the loggia. For a balcony, the best option is 0.5x1 or, in last resort, 1x1.
As for the thickness, you can buy absolutely any polystyrene foam for a balcony. The only thing that should be guided in this case is such an indicator as the area of \u200b\u200bthe loggia. After assembling the warming cake on the balcony, there should be enough free space for a comfortable pastime. Most often, the owners of the loggias of typical Soviet-built houses choose polystyrene foam with a thickness of 40-50 mm.
The density of this type of insulation can be found by looking at the marking. The best answer to the question of how to sheathe a balcony from the inside is to use 15-25 grade polystyrene foam. The higher the numbers, the lower the thermal conductivity of the material, and the more brittle it is. If the expanded polystyrene is supposed to be covered with decorative plaster or wallpaper in the future, it is worth buying thicker plates. If lining or panels will be used as a quality, you can take loose sheets that retain heat well.
Where to begin?
So, how to insulate the balcony inside with your own hands, you now know. Next, let's look at how to do it right. Before proceeding with the installation of the insulating "pie", it is necessary to carefully prepare the loggia itself. First of all, the wooden floors are dismantled. Then proceed to repair the parapet. If there are through cracks in it, they must be sealed with sealant. Chipped close up cement mortar or moisture resistant putty. Similarly, prepare the walls, floor and ceiling.
Loggia waterproofing
Having wondered how to properly insulate the balcony with their own hands inside, the owners of the apartment must first of all make sure that it is always dry in this small room. Waterproofing during this operation is considered mandatory (especially when using mineral wool as a heater). In its absence:
the service life of the balcony finish will be reduced;
all metal structures will quickly rust;
because of high humidity start to develop different kind fungi, resulting in an unpleasant odor on the loggia.
Sometimes on balconies not insulated in this way, they even begin to collapse support structures which, of course, is very dangerous.
The easiest way to waterproof a balcony is to use bitumen-polymer mastic. It is heated to a liquid state, the floor is poured into it and the parapet is smeared in 2-3 layers. Sometimes roll materials are also used to waterproof the balcony.
What kind of glue do you need
Those who wondered how to insulate the balcony inside with polystyrene foam or polystyrene foam should, among other things, take care of using suitable glue to fix the sheets. It is allowed to mount this material directly on the mastic (on polymer-bitumen - immediately, on bituminous - after complete drying). In this case, special glue should be used. It's called Bitumast.
What else to buy
Thus, you now know how to insulate the balcony inside with your own hands. Photos of polystyrene sheets - the most suitable material for this purpose - can be seen on the page. However, in addition to them and glue, to insulate the balcony, you will also need to prepare:
reinforcing mesh,
fungus dowels,
polyurethane foam (without toluene),
decorative plaster or wallpaper.
pasting technology
So, next, let's see how to insulate the loggia from the inside. Start the installation of sheets should be from the corner. This rule is true both when pasting a parapet, and walls or a ceiling. Actually the installation operation itself is performed as follows:
Styrofoam sheets are roughened. To do this, they are passed with a special needle roller. Treated in this way, they will hold much better.
A support rail is attached to the bottom of the parapet.
The adhesive solution is evenly applied to the surface of the wall, ceiling or parapet.
Firmly press the polystyrene foam to the surface.
Mount the material for insulating the balcony from the inside in such a way that the joints between the sheets have a T-shape (as when laying bricks). After the plate is glued, it should be additionally fixed with mushroom dowels (5 per sheet). Holes for them can be drilled directly through the sheets. On final stage handle joints. In this case, building foam is used.
Reinforcing mesh gluing
Expanded polystyrene is an excellent answer to the question of how best to insulate a balcony inside. However, decorative plaster on this material does not hold very well. To remedy the situation, use a special reinforcing mesh. Mount it as follows:
Previously, the polystyrene foam surface of the ceiling, parapet and walls is completely coated with glue (for polystyrene).
Another layer of glue is applied on top of it. Its thickness should be such that the mesh joints do not protrude above the surface plane.
fine finish
So, we have figured out how to insulate the balcony with our own hands. step by step photo this process is shown above. As you can see, this procedure is relatively simple. At the final stage, the dried adhesive surface is passed with a special grater to give it a roughness. Next, start applying decorative plaster. You can also wallpaper the balcony.
Second way
The loggia isolation technique discussed above is suitable when using dense polystyrene foam. And if the owners decided to buy mineral wool as an insulator? How to insulate a balcony with your own hands? A step-by-step (photo of the process is presented below) work guide in this case will look like this:
On the parapet, walls, floor and ceiling, a frame of wooden beams. The step between its elements should be equal to the width of the plates of the selected insulation. The beam can be fixed to the concrete parapet with self-tapping screws. For balconies with metal railings, an independent paving construction is assembled.
Further, the insulation itself is inserted between the elements of the frame. The material is attached to the concrete parapet with “fungi” (expanded polystyrene can be additionally glued). If the fence is metal, it is better to use cotton wool and insert it by surprise. If expanded polystyrene is chosen for insulation, you can, for example, fix it on reverse side plywood frame and glue the material to it.
It is stretched over the insulation. It is better to fasten it with thin laths (two on each side of the beam).
the balcony is trimmed with clapboard, plastic panels, drywall or plywood. Attach the material to the bars of the frame.
How to insulate the floor
The base of the balcony is isolated last. The floor is preliminarily waterproofed, and then logs are installed on it. The answer to the question of how to insulate inside is simple. Most often, expanded polystyrene or mineral wool is laid between the bars. You can also use expanded clay. A vapor barrier is attached over the insulation, and then a floor or floor is stuffed. edged board. Then the floor is covered with linoleum or finished with any other suitable material.
Balcony heating
Whatever answer to the question of how to insulate the balcony inside, the owners of the house choose for themselves, subject to the installation technology, in the future it will be possible to have a good time here, including in winter. However, on very cold days, even an insulated loggia may require additional heating. endure central heating regulations are strictly prohibited. That's why best solution will set here normal electric heater. It should be placed against the wall separating the balcony and the apartment. It is not recommended to install heaters near the parapet. The fact is that in this case, due to the rising warm air on the balcony, the windows will begin to fog up heavily.
You can also arrange on the loggia
Warm floor
This work is done as follows:
Thermal insulation material is laid on the floor.
Installed metal
Installed heating cable.
A thermostat is hung on the wall.
Poured concrete screed 30-40 mm thick.
The floor covering is laid.
Well, we hope we answered the question in sufficient detail about how to insulate the balcony inside with our own hands and how to do it right. The most important thing when assembling a "pie" is not to break required technology. In this case, the balcony will turn out cozy and warm.
IN modern apartments the balcony has already ceased to be just a place where clothes are hung out to dry, vegetables are stored for the winter, or used as another pantry.
A modern balcony is another small room, most owners have it separate, and some expand their living space in this way (enlarge rooms).
Thanks to the diversity building materials now it’s very easy to redevelop: some tenants expand their balconies within the boundaries of the apartment, some, on the contrary, reduce, for example, they divide a long balcony into two parts (one remains as a balcony, the other becomes part of a room or kitchen).
There are many options, of course, and they all depend on individual needs. But no matter what option you choose - a separate room or an extension of the living space - the balcony must be insulated without fail.
Of course, you need to be prepared for the fact that the area of \u200b\u200bthe balcony will decrease after it is insulated inside. But in cases where it is very difficult to insulate a balcony from the outside (for example, a high floor) and poses a danger to specialists performing this work, insulation inside is the most rational option.
So, first, decide on the type of insulation.
Insulation options for balconies
The most popular and most commonly used material for insulating a balcony is penoplex.
Penoplex, or the more familiar name polystyrene, is foamed extruded polystyrene, a material that is the most effective insulation that has a special homogeneous structure. Penoplex is distinguished by sufficient strength, excellent water resistance, fairly low thermal conductivity and, importantly, ease and speed of installation. With all the great advantages, penoplex is flammable, so when installing it, this quality should be taken into account and a fire-resistant finishing material should be selected (for example, plaster will give the desired combination).
The next type of insulation, quite suitable for balconies, is polyurethane foam. It is distinguished by its lightness and strength, low thermal conductivity and vapor permeability, the absence of combustible properties, which also adds to it a plus as a material used for indoor work. Not susceptible to the appearance of fungal raids. Polyurethane foam refers to gas-filled plastics, another name for it is foam rubber, it has a peculiar structure, due to which it has the lowest thermal conductivity in comparison with other insulating materials.
If you choose polyurethane foam as a heater, keep in mind that it is impossible to apply it yourself if you do not have special equipment. Polyurethane foam is applied only by spraying. Due to which it is airtight and takes away from the room relatively small area due to the fact that it does not need to be applied in several layers.
Penofol became the most modern insulation. This is the thinnest material with a multilayer structure based on polyethylene foam covered with a layer of foil. Penofol insulation means creating reflective insulation.
This environmentally friendly product has the highest thermal resistance, due to which a room insulated with foam foam retains heat in winter and creates a cool microclimate in summer. This material also provides good sound insulation, its advantages also include ease of installation. Penofol is produced in rolls, and this gives an exceptional opportunity to avoid unnecessary trimming and selection of joints, which gives the material an additional economic benefit.
The most ancient and proven type of insulation is mineral wool (it is a synthetic material with a fibrous structure). Of course, this type of insulation has proven its excellent thermal insulation properties, heat resistance, fire resistance, reliability and long term operation.
Each of the heaters listed above has, of course, its pros and cons, and differs in cost. But all of them are perfect for warming the balcony, they are commercially available in any hardware store and are fairly easy to install with your own hands, except for polyurethane foam (as mentioned above, you need special equipment for spraying it). The basic principles of installation of other types of heaters are approximately the same, they differ in some nuances.
Having considered all types of heaters and having decided to carry out work on the insulation of the balcony on your own or with the involvement of specialists, you can make the final decision - how to insulate the balcony inside.
And, in order for you to better understand the basics of installation, we will consider below the procedure for insulating a balcony with one of the types of insulation, for example, penoplex.
Insulation of the balcony inside with foam
Before you start insulating the balcony inside the building, you need to glaze it (this will immediately increase the air temperature in the room), and also keep in mind that all insulation work is carried out only at positive temperatures.
Necessary materials and tools
To start work on the insulation of the balcony, you need to study the list necessary tools and materials and prepare them. So, for work you will need:
- perforator;
- screwdriver;
- jigsaw;
- level;
- whisk;
- putty knife;
- hammer;
- roulette;
- dowel;
- self-tapping screws;
- container for mixing glue, putty;
- special container for primer solution;
- wooden bars;
- metal corners (for attaching the frame to concrete);
- building mixtures (primer, glue for foam, putty for sealing cracks);
- foam boards 10 cm thick (for the first layer of insulation);
- foam boards 5 cm thick (for the second layer of insulation);
- material for interior decoration balcony.
The procedure for warming the balcony
To begin with, you should inspect the surfaces of the walls, floor and ceiling on the balcony, if cracks or chips are found, then they must be repaired. After that, clean the surfaces from dust and dirt.
When the walls are cleaned, they must be primed with a special primer solution. This will improve the adhesive properties of special mixtures, which will subsequently hold foam. The primer is applied with a roller.
Installation of foam plastic involves carrying out work in one of the ways: the plates can be glued or attached with dowels. However, many are trying to give additional reliability to the mount, so they use adhesive method with control fixing of plates with a special dowel.
A special dry mixture of glue must be diluted in a prepared container to a certain consistency (the preparation technology and the ratio of water and mixture are always indicated by the manufacturer on the package). Stirring the mixture is done with a whisk.
When the glue is ready, it is applied to the prepared foam sheets (10 cm thick plates are taken for the first layer) and the gluing is started. You need to know that the glue is applied to the foam sheet by the point method using a construction spatula, and the gluing of the plates always starts from any lower corner of the structure.
When the first layer of foam boards is glued, a crate is made using wooden bars measuring 50x50 cm.
The bars are cut to the required dimensions using a jigsaw. The bars are fastened to concrete (floor perimeter, ceiling) and to the first layer of insulation - with dowels, and they are connected to each other with self-tapping screws. Holes for dowels are drilled with a puncher.
In the gaps between the bars (in the cells) a second layer of insulation is placed - foam boards, but for the second layer 5 cm of thickness is enough. The boards are also glued on.
It is very important - the second layer of foam must cross over and completely overlap the seams of the first layer of insulation.
The frame for the floor is mounted from the same bars, attaching them to the floor using special iron corners and dowels.
The resulting cells in the floor frame are filled by gluing two layers of insulation. Then the finished floor is covered with ordinary plywood sheets by attaching them with self-tapping screws using a screwdriver.
All stages of installation are accompanied by measuring the evenness of the resulting surface, do this with the help of a level.
This completes the process of insulating the balcony with a heater.
The next step is the internal Finishing work. As a finishing material, you can use any material you like. Most often, lining (plastic or wooden), plastic plates are used to finish the walls of an insulated balcony. If your choice falls on the plaster, then this will provide additional protection your design (given the property that the foam is flammable, and the plaster will provide it with the necessary fire resistance).
Both laminate and linoleum are perfect for finishing the floor. It is possible to install a warm floor on the balcony. Again, it all depends on your taste and needs.
What materials for warming a balcony or loggia will effectively cope with the task? I suggest you consider 5 heat insulators with which I happened to work. I will tell you on what qualities they are selected and why they are considered the best.
Types of thermal insulation materials
Balcony insulation can be performed with the following heat-insulating materials:
Option 1: mineral wool
Mineral wool is a roll or board material, which consists of fine mineral fibers. The latter are obtained by melting and spraying rocks or blast-furnace slag.
Characteristics:
To insulate the balcony from the inside wireframe you can use glass wool, which is cheaper than basalt wool. In this case, during its installation, it is necessary to carefully protect the respiratory organs, eyes and hands.
Advantages:
- Versatility. Basalt wool can be used to insulate the balcony inside and out. Moreover, the insulation of surfaces can be carried out both in a frame way and wet:
- Let me remind you that when frame insulation panel or sheet are used Decoration Materials- drywall, plastic panels, lining, siding, etc.;
- When finishing wet way the surface of the insulation is plastered;
- Plates of high density grades can even be laid under a screed for floor insulation;
- Environmental friendliness. Basalt wool does not contain harmful substances, and even during installation, unlike glass wool, it practically does not cause irritation on the skin;
- Vapor permeability. Insulation allows the walls to "breathe", thanks to which a favorable microclimate is formed in the room;
- Fire safety. Mineral wool does not burn and can withstand high temperatures.
Flaws:
- Absorbs moisture. When performing work on insulation, it is necessary to ensure high-quality vapor and waterproofing;
- Price. The price of basalt wool is higher than some other heaters.
Price:
Expanded polystyrene is a lightweight polymer insulation, one of the most common heat-insulating materials due to its low price.
Option 2: Styrofoam
Expanded polystyrene, or simply polystyrene, is a polymer insulation in the form of plates formed by small granules.
Characteristics:
Advantages:
- Light weight. Styrofoam is the lightest slab insulation;
- Low price. The cost is much lower than the price of basalt wool;
- Versatility. Like basalt wool, it can be used for insulation in any way, both from the inside and outside;
- Moisture resistant. The material absorbs moisture to a lesser extent than mineral wool.
Flaws:
- Zero vapor permeability. This disadvantage can lead to an increase in indoor humidity, mold on the walls, etc. High-quality ventilation will help to eliminate it;
- Fire hazard. Styrofoam manufacturers, especially lesser-known ones, rarely add fire retardants to the Styrofoam composition. Therefore, it ignites quite easily and burns well;
- Low strength and brittleness. This drawback matters if the insulation boards are plastered after installation. Surfaces insulated in this way are unstable to shock loads;
- Low environmental friendliness. Styrofoam itself does not threaten health in any way, but in the process of burning it releases toxins. Inhalation of these substances leads to severe poisoning.
Price:
Option 3: Extruded Styrofoam
Extruded polystyrene foam, also known as polystyrene foam, is made from the same raw materials as regular foam. However, thanks to a special insulation technology, it has higher characteristics.
Characteristics:
Advantages. From the data in the table it can be seen that the penoplex has a low thermal conductivity and high strength. In addition, it has some other advantages:
- Moisture resistance: Penoplex absolutely does not absorb water, therefore it does not need waterproofing;
- Fire safety. All well-known manufacturers add flame retardants to the composition of this material, which makes the insulation for the balcony low-flammable.
Flaws:
- High price. For this reason, it makes sense to use penoplex only in cases where a large load will be placed on it, for example, in the case of wet insulation of walls and ceilings. You can also perform thermal insulation of the floor under the screed;
- Low vapor permeability. The vapor permeability coefficient of foam plastic is slightly higher than that of polystyrene, however, the material is still not "breathable".
Price:
Option 4: polyurethane foam
Polyurethane foam is another type of polymer insulation. Its main feature is that it is applied to the surface in the form of foam.
Characteristics:
Polyurethane foam is also used for insulating balconies in the form polyurethane foam. With its help, thermal insulation of various cracks is performed.
Advantages:
- Low thermal conductivity. As can be seen from the table, polyurethane foam has the lowest thermal conductivity. In addition, it is applied to the surface in a continuous layer, due to which it retains heat in the room more efficiently;
- Moisture resistant. Thanks to this quality, it does not require the use of waterproofing;
- Good adhesion. This allows you to apply insulation on any surface.
Flaws.
- Requires special equipment. Polyurethane foam cannot be applied by hand. This procedure should be carried out exclusively by highly qualified specialists with special equipment;
- Zero vapor permeability. Like other polymeric heaters, the material does not breathe;
- Increase in thermal conductivity over time. The gas that fills the structure of the polyurethane foam gradually leaves the shell. As a result, its thermal conductivity increases slightly;
- High price. In addition to the cost of the material itself, the cost of insulation work is added to its price;
- The impossibility of plastering. To finish the balcony from the inside or outside, in the case of using polyurethane foam, it is possible only in the frame way;
- Toxic in liquid form. When working with polyurethane, it is necessary to use personal protective equipment, as it is toxic. After hardening, the material is safe for health.
Price. Different manufacturers have different prices for polyurethane foam insulation. On average, the cost, taking into account work, is about 500 rubles. for 1m2
Option 5: penofol
Penofol is a thin roll insulation, which consists of two layers:
- Foamed polyethylene - performs the function of a heat-insulating material;
- Foil - reflects heat from insulated surfaces into the room.
Thus, given material apply only for internal insulation balconies and loggias.
Characteristics:
Advantages:
- Little weight. The material is easily attached to any structure;
- Moisture resistant. This allows you to use penofol as waterproofing material if, for example, you insulate a balcony or loggia with mineral wool;
- Small thickness. Thanks to this, the material does not take away extra space in room.
Instructions for the use of penofol require its location during installation with the foil side to the room. Otherwise, the material will not reflect heat from the surfaces.
Flaws:
- Zero vapor permeability. I have already spoken of the consequences of this deficiency;
- High thermal conductivity. Penofol is a thin material, so it is not enough to fully insulate the room. Therefore, it is usually used as additional thermal insulation.
Price. The price starts from 50-80 rubles per 1m2.
That's all the heaters that I wanted to acquaint you with. Well, to decide how and how best to insulate the balcony, you now have to do it yourself.
Conclusion
Now you know all the basic qualities of the most common thermal insulation materials, and you can do it yourself right choice. I recommend watching the video in this article. If you have any questions, write comments, and I will answer as soon as possible.
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 it was built. apartment house. 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. The result is not only an attractive appearance buildings, but also significantly increases its strength. By the way, a double-glazed window will significantly warm the room.
If the owner of the apartment changes the windows to plastic, 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.
Loggia insulation Secrets of skill from Alexei Zemskov
The fire safety of this heater is on 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 and itchy 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:
The thickness of the wall from the edge of the interior to the exterior, taking into account 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.
