Insulation of a small balcony. The best way to insulate a balcony inside: what materials to choose. How to insulate a parapet using lathing

Loggia is several square meters, which can serve a variety of purposes. To use this premises all year round, you need to ensure a comfortable temperature there. Every home craftsman can transform it into a cozy, useful and well-equipped space.

Are you planning to start arranging these additional square meters, but don’t know how to insulate the loggia with your own hands and what materials will be needed for this? We will help you deal with all the issues - our article provides recommendations for choosing insulation and discusses step-by-step instructions for thermal insulation of the walls, ceiling and floor of the loggia.

You should start, of course, with planning. You should decide on functional purpose this small room. If you plan to use it as a warehouse for things that are not very necessary, then insulation does not make much sense. But the loggia can be turned into an office, a small gym, winter Garden and so on.

There are also restrictions. For example, a loggia cannot be used as kitchen area, that is, install a stove there, a sink for washing dishes, etc. It is also prohibited to install a centralized heating system in this area.

There are a number of other restrictions that may be associated with architectural features And fire safety building. This may be a ban on glazing above a certain floor, on changing the appearance of the building, the height of the fence, etc.

As practice shows, many manage to somehow circumvent these standards and arrange a loggia to their liking. Before starting work, it doesn’t hurt to coordinate your plans with supervisory authorities or prepare for problems to arise after the rework is completed.

Installation of electrical wiring, lighting and heated floors during insulation of the loggia must be thought out in advance so that damage to the heat-insulating material is minimal

But under no circumstances should openings be made in load-bearing wall, only the holes provided for in the original design are allowed. Even taken from the loggia window-door block may pose a danger.

To keep the loggia warm, you will need high-quality glazing. It is better to order it from a reliable company. Double-glazed windows will do the job perfectly.

Part of the space will be “eaten up” by a layer of insulation. These centimeters will have to be sacrificed in order to reliably protect the house from the cold. Loggias located on the lower floors are most often insulated from the outside. ABOUT the best materials for external wall insulation we.

From the very beginning, you need to consider options for heating this space.

There are not so many of them, because only suitable for a loggia:

  • electric TP;
  • portable heater.

Considering that the installation area is small, you can spend money on such convenience as a TP. Cable systems easy to install, you can do all the work yourself. Infrared flooring is more difficult to install; it requires almost perfect level base, but electricity costs during operation will be moderate.

But most simple solution there will be use, especially if the loggia is not used every day, but only from time to time. Installing heated floors will require more expense and effort.

The choice of materials and options for insulating a loggia with your own hands is quite wide.

Among the most popular it is worth noting:

  • mineral wool;
  • Styrofoam;
  • polyurethane foam;
  • expanded polystyrene;
  • penofol, etc.

Mineral wool has a low price, but this is almost its only advantage. To lay such material, you will need to first arrange the lathing. Mineral wool is sensitive to moisture; when wet, it loses its beneficial features, so it is not always suitable for a loggia.

You need to provide a place for installation in advance. Usually a niche is made on the wall for these purposes. suitable size. A temperature sensor placed in a corrugated tube is placed among the turns of the cable TP. It will also need to be connected to the thermostat.

In most apartments, balconies require additional insulation, which directly affects the comfort of the entire apartment. With basic finishing in summer time it's very hot on the balcony, and winter period- Cold. To prevent this from happening, you need to know how to insulate a balcony with your own hands. Step by step photo and the video from this article will help you carry out insulation correctly at minimal cost.

Where to start insulating a balcony

The method of insulation and the type of materials directly depend on the location of the apartment. If the apartment is on the top floor, the roof often overheats in summer, creating a strong Greenhouse effect, which contributes to overheating of the balcony.

If the balcony was made of low-quality slabs, they crack and allow moisture to pass through.
In any case, the balcony is insulated if it faces north or south. The south side provokes heat on the balcony, and the north side does not warm up in winter.

During thermal insulation, the balcony further improves the quality of sound and moisture protection.
A high-quality insulated balcony allows you to use it at your discretion. There are practically no disadvantages of such thermal insulation, and the advantages are immediately noticeable.

Loggia floor insulation scheme

Before insulating the balcony from the inside, you prepare the surfaces yourself.

  • Cabinets, shelves, fasteners, cabinets are removed.
  • The ceiling and walls are cleaned of flaking particles.
  • If there is floor covering, it is removed.
  • After this, the integrity is checked balcony slabs. If the slabs have many cracks or chips, they need to be removed.
  • These areas are then covered with cement mortar.
  • The end result is a rough ceiling, walls and floor that are ready for further insulation.
  • In some cases, before isolation, finishing plaster. This is necessary if the surfaces interfere with the installation of insulation and have uneven surfaces.

    Before insulation, the balcony must be glazed. The best option suitable for balcony glazing double-glazed window with argon filling. At severe frosts, it is better to install three-chamber double-glazed windows.

    Step-by-step instructions for insulating a balcony

    Insulating a loggia is divided into several steps:

    Step 1. After installing the windows, all cracks are filled with sealant and foam for installation. If there are large potholes or gaps, they need to be repaired.
    Step 2. For waterproofing balcony surfaces, roofing material is used, bitumen mastic, liquid formulations deep penetration.
    Step 3. The insulation material is fixed, and then the vapor barrier.

    Step 4. The balcony is decorated with your own hands.

    Step 5. The flooring is being installed.

    How to insulate a loggia with penoplex

    Penoplex insulation allows you to protect the balcony from cold and dampness. This material is resistant to mechanical impact. The side part can be ribbed or smooth. The first option allows you to more effectively fix the plates to each other.

    Photo of penoplex insulation

    If the average annual temperature is low, material up to 7.5 centimeters thick is used. If in winter time the temperature does not drop below -25 degrees, a material 4 centimeters thick is required.

    Methods of fastening penoplex depend on the further finishing. When finishing from plasterboard, lining, fastening is done using mushroom dowels. If the surface is plastered, then the penoplex is glued.

    To insulate a balcony with penoplex, follow these steps:

    • The slabs are fixed on the primed surface.
    • Penoplex is attached using the tongue-in-groove or joint-in-joint method.
    • The slabs are fixed on top with special dowels.
    • The joints are sealed with tape.
    • The joints are filled with installation foam (composition without toluene).
    • On top there is a vapor barrier, sheathing and surface finishing.
    • Penoplex insulation can be done after installation of the sheathing.
    • The insulation is placed between the bars.

    Do-it-yourself insulation of a balcony with polystyrene foam

    Penoplex is durable, but if this indicator does not play an important role, then you can use standard polystyrene foam to insulate a balcony or loggia.

    Photo of foam insulation

    Polystyrene foam for insulation is available in the form of sheets with a thickness of 5 to 15 centimeters.
    To insulate the balcony from the inside, sheets 10 centimeters thick are used.

  • Before insulation, the surfaces are coated with a primer with deeply penetrating properties.
  • Glue is applied to the sheets.
  • The sheet is pressed to the surface and fixed with plastic dowels.
  • The joints are sealed with foam for installation.
  • The seams are closed with tape.
  • A reinforced fiberglass mesh is attached to the glue.
  • Any type of finishing can be done on top of the mesh.
  • Polystyrene foam can be installed using the principle of polystyrene foam in the sheathing.
  • How to insulate a balcony with clapboard yourself

    Insulation with clapboard cannot be of high quality if the balcony does not have sufficient heating. If there is no heating, then basic insulating material is placed under the lining.

    Photo of lining on the balcony

    To install the lining, a wooden sheathing is required, which is mounted horizontally. Foam plastic or penoplex is fixed in the gaps. A lining is installed on top of the insulation. It is fixed to the sheathing. Such insulation can be done on a durable, reliable balcony.

    Mineral wool for insulating balconies

    Insulating a balcony with mineral wool makes the structure lighter. This material allows you to protect the surface from cold, heat and moisture. Poor installation reduces the properties of the insulation by almost half.

    Photo of mineral wool

    A sheathing is placed on the surface coated with a waterproofing compound. The plates are fixed with special glue and dowels. In the corners, fixation is done with extreme caution. The insulated surface is covered with a vapor barrier.

    Balcony insulation scheme

    After which the surface is ready for finishing. When installing any insulation material, compliance with certain rules guarantees high-quality insulation of the balcony. Before you start work, carefully study the features of the selected material and how to install it correctly. Remember that the heat in your apartment or country house directly depends on the insulation.

    How to insulate a balcony with your own hands now you know and can choose suitable material for performing thermal insulation work. Step by step photogood helper during DIY repairs. If you learn how to properly insulate a loggia at home, then you will have new profession, which is in demand today.

    Creation favorable microclimate on the loggia involves not only insulating the walls, the entire space must be airtight. Floor and ceiling surfaces are also sheathed with material with a low degree of thermal conductivity. In our article you will learn how to properly insulate a balcony from the inside.

    Selecting a thermal insulator

    Advantages and disadvantages are inherent to each type of thermal insulation. In order to choose the most suitable insulation, you should compare the main characteristics of heat insulators.

    The most common thermal insulator options:

    • Extruded polystyrene foam (penoplex);
    • Foamed polyethylene (penofol);
    • Polyurethane foam (PPU);
    • Styrofoam;
    • Mineral wool.

    Mineral wool

    The thickness of the sheets varies from 2 to 20 cm. Mineral wool is divided into three types, depending on the components of the raw material:

    • Stone;
    • Slag;
    • Glass.

    An example of installing mineral wool on a loggia. The material is placed into the prepared structure. The mounting frame can be made of metal profiles or wooden blocks.

    Manufacturers produce cotton wool in the form of mats and soft rolls. In some cases, one side is covered with foil. Aluminum foil improves the level of thermal insulation.

    When laying mineral wool, the foil side should be directed inside the room. This principle allows heat to be reflected from the aluminum coating and returned to the room.


    This method is quite common, despite the existence of cheaper heat insulators. The insulation is resistant to fire and does not contribute to its spread. When mineral wool is heated, no harmful substances are released into the air.

    The main disadvantage is that moisture is destructive; a vapor barrier is required.

    Please pay attention to the integrity of the mineral wool packaging before purchasing. Moisture negatively affects the properties of the heat insulator. For high-quality insulation, it is necessary that the loggia space be dry.

    Polymer-based insulation

    Penoplex, polyurethane foam, polystyrene foam, foamed polyethylene are polymers treated with foam compounds.

    Advantages:

    • The presence of gas bubbles provides not only good level thermal insulation, but also light weight of the slabs;
    • High degree of moisture resistance;
    • The materials are durable;
    • Antifungal resistance;
    • Simplicity and convenience when laying slabs or sheets, as well as rolls (foamed polyethylene);
    • An economical repair option, provided you choose polystyrene foam as insulation.

    Main disadvantage: support the spread of flame during a fire, emit harmful substances during the combustion process.

    When choosing polystyrene foam and other polymer-based materials, it is necessary to correctly select the thickness of the slabs and determine the density

    If you plan to use the space in winter, then choose a thickness of 50 mm. The density is determined by further coating - for putty, a value of 25 kg/cube is suitable. m.

    1. Foam sheets

    Insulator slabs (expanded polystyrene) during installation.

    Polystyrene foam is a low-cost method of insulating a loggia, but it is considered a fairly fragile material, so lathing is required for installation. A worthy replacement is extruded polystyrene foam; its installation does not require the creation of a special frame.

    2. Penoplex

    Extruded polystyrene foam boards (50 mm thick) are used as insulation. The seams between the elements are sealed with polyurethane foam. Penoplex is attached using special disc-shaped dowels (“fungi”).

    3. Penofol

    The material is used as a separate heat insulator; foam polystyrene foam can also be used to provide vapor barrier. Due to the foil side, warm air is reflected and retained in the room.

    In order to speed up the insulation of the structure, you can use alternative method thermal insulation - spraying polyurethane foam (PPU).

    4. Polyurethane foam

    PPU is one of the most modern heat insulators. The cost of application services is considered high compared to other analogues, but many have managed to evaluate the performance properties of polyurethane foam. For this insulation Characterized by high thermal insulation rates due to its fine-porous structure.

    Spraying of polyurethane foam is carried out by specialists; one day is enough for installation work; complete drying also does not require much time.

    The main stages of work on insulating the loggia space

    In order to increase usable area in your home and to operate the premises all year round you need to:

    1. Seal gaps, if any. Carefully examine the room to eliminate all design flaws. As a rule, cracks are filled with polyurethane foam, even if they are large.

    After complete drying, it is necessary to trim off the excess.

    2. Glazing with reliable double-glazed windows.

    3. Organize waterproofing layer. To protect against moisture, waterproofing with penetrating properties is used - “Penetron”, “Aquaton”, etc. The composition is applied with a roller, brush, or spray. This impregnation penetrates into the thickness, so the walls become as resistant to adverse weather as possible and their strength characteristics improve.

    The installation of a waterproofing layer allows you to eliminate the most minor surface cracks that may not be visually visible.


    4. Thermal insulation layer. To organize a warm structure, we use the selected material (polyurethane foam, penoplex, polyethylene foam, polystyrene foam, etc.).

    5. Installation of a vapor barrier layer. In order to make a vapor barrier, you should use special polymer membranes(“breathable”), as well as films “Rockwool”, “Izospan”, penofol.

    When using penofol, lay the insulation so that the side covered with foil is directed into the room. Subject to this condition, heat will constantly be reflected from the foil, lingering inside the space.


    6. Final finishing of walls, floor surfaces and ceilings.

    WITH detailed description Each stage can be found in the article: .

    Balcony room decoration

    Goals for creating interior decoration:

    • External masking of the heat insulator;
    • Organization of a favorable indoor environment.

    To create a balcony interior, you can choose various options finishing. Plaster, plastic panels, MDF, lining, plywood, gypsum board sheets and even a block house are perfect for the finishing layer.

    Lining panels are environmentally friendly and reliable. One of the main advantages of the finishing material is rigidity. The lining is fixed to a wooden frame-crate.

    The walls of the loggia are covered with clapboard, the flooring is laminate.

    Facing the balcony with a block house.

    The plastic panels have grooves for connecting elements. Plastic version lining has less rigidity and strength than wood.

    Installation of gypsum board sheets on metal profiles. Plasterboard slabs can be decorated with wallpaper, painted, or covered with decorative plaster.

    Until recently, the balconies of city apartments served as a kind of storage room - people stored preserved food and various things there. What’s more, all sorts of unnecessary rubbish was taken out onto the balconies, which was a pity to throw away. However, today these premises are increasingly used as additional living space. And to implement such an idea, you need to take care of insulating the balcony.

    If you insulate your balcony, you will be able to not only expand the living space of your apartment relatively cheaply, but also significantly reduce heat loss from your home. The fact is that it is through the balconies that most of the heat escapes. But in order for everything to be done efficiently, you need to know where to start. With a well-designed scheme, turn cold balcony albeit in a small, but almost complete room, it will be much easier.

    So first sketch rough plan works - it will include:


    Important information! The balcony can be insulated both from the inside and outside. But since you will be doing the work on your own, that is, without the help of specialists, it is better to resort to internal insulation.

    Stage No. 1. Choosing insulation

    On modern construction market there is a lot of warmth insulating materials, but more suitable for a balcony:


    As for foam plastic and EPS, the laying of these materials is carried out using almost the same technology (the only exception is the form of adhesion - with EPS it is better due to the use of grooves).

    It is better not to use mineral wool for a balcony - the installation procedure will be more labor-intensive, and the condensation that inevitably forms on the balcony is undesirable for this material. Expanded clay, for obvious reasons, can only be used for floor insulation (the insulation technology will be described in detail below).

    And if we add to all of the above the fact that the balcony should in no case be overloaded, then it becomes obvious: the most suitable option- this is foam plastic 4-5 cm thick, which costs less than polystyrene foam or mineral wool.

    Stage No. 2. We carry out glazing

    If your balcony is already glazed, you can skip this step. The glazing procedure itself largely depends on the parapet installed on the balcony. If we're talking about about the iron sheathing, then you must build it up using foam blocks or ceramic brick. It is important that the resulting wall thickness exceeds 10 cm. And if you have a reinforced concrete parapet, you can immediately begin installing windows.

    Today, many (especially fans of environmentally friendly building materials) prefer double-glazed windows with wooden frames. It is worth remembering that such structures need to be processed antiseptic and paint regularly. You can learn about installing double-glazed windows with wooden frames from the video below.

    Video - How to install a wooden window with double glazing

    However, the majority of consumers still buy PVC windows. When purchasing, choose a special one plastic profile, characterized by increased rigidity and strength properties. In addition, the profile must have good thermal insulation properties.

    Still have plastic windows it should be:

    • 5-chamber profile;
    • 2-chamber (if you live in middle lane) or 3-chamber (if in a more severe climate) double-glazed window;
    • reinforced reinforcement.

    After installing the PVC structure ordered according to the dimensions of the balcony (the work should be carried out by specialists), you can proceed directly to insulation.

    Stage No. 3. We insulate the floor

    Let's look at how to insulate a balcony from the inside with your own hands using polystyrene foam (although the technology described below is also suitable for polystyrene foam).

    Table. Insulating the floor on the balcony

    Steps, no.Short descriptionIllustration
    Step #1First, prepare the working surfaces - seal with foam all the cracks found in the concrete, as well as at the joints between the slabs and the wall.

    Step #2Mark the floor for the subsequent construction of the sheathing. In this case, it is important that the pitch of the sheathing exceeds the width of the insulation sheets by approximately 10 mm.

    Step #3Lay the slats according to the previously made markings (the approximate size of the bars is 4x4 cm, but their width must correspond to the thickness of the insulating material). The first and last slats should be 50-100 mm away from the walls. Connect the slats using self-tapping screws.

    Step #4Place sheets of foam plastic between the lathing slats, gluing them to the floor liquid nails or special glue. Blow out any resulting voids with polyurethane foam.

    Step #5Lay a vapor barrier layer on top of the insulation. Lay a vapor barrier layer on top of the insulation (necessary to increase thermal insulation and prevent the formation of condensation). If you use regular PET film, then under no circumstances place it on the “cold” side of the insulator. If you are laying foil insulation, then do it with foil to the foam.

    Step #6Attach sheets of plywood or chipboard on top, and the thickness flooring must be at least 20 mm. Attach the sheets to the slats using self-tapping screws.

    Step #7All that remains is to lay the finishing coating, which can be carpet or linoleum.

    Important information! There is another way to insulate the floor on a balcony with polystyrene foam: sheets of foam plastic are attached to a leveled and cleaned surface, and poured on top thin screed from a previously prepared dry mixture solution. As finishing coating Ceramic tiles can be used here.

    Alternative option. We use expanded clay

    As noted earlier, the floor on the balcony can also be insulated using expanded clay. This material is also inexpensive, and its installation is not difficult. Let's get acquainted with the algorithm of actions.

    Step #1. Lay it on the floor first waterproofing film with an exit to the walls of 10 cm.

    Step #2. Place the beacons around the perimeter in increments of approximately 25 cm, being careful not to lean them too far against the walls.

    Step #3. Cover the floor with a 15 cm thick layer of expanded clay and distribute the material evenly over the surface.

    Step #4. Moisten the expanded clay with cement laitance (this is an aqueous solution of cement).

    Step #5. Fill the expanded clay with a layer of concrete or self-leveling mixture. This must be done carefully so as not to damage the structure of the insulator.

    Step #6. Wait for the screed to dry completely. After this, you can begin laying the topcoat.

    Stage No. 4. We insulate the walls

    The technology here is almost the same as for floor insulation. Follow these steps:

    Step #1. Mark the future location of the slats on the walls (as well as for the floor).

    Step #2. Attach the slats in accordance with these markings.

    Step #3. Apply polyurethane foam to the surface using wave-like movements. At the same stage, you should drill holes for the dowels.

    Step #4. Attach the foam sheets using plastic mushroom dowels.

    Step #5. Blow out all the resulting cracks with foam, then seal with mounting tape.

    Step #6. Lay a waterproofing layer on top - for example, penofol, which will also serve as thermal insulation.

    Step #7. Seal the seams at the joints with foil tape.

    Step #8. Mount the counter-lattice on top of the foam foam and install the finishing material.

    Stage No. 5. We insulate the ceiling

    This procedure is also performed using a similar technology, but some differences still occur.

    1. First, make a marking along which the hangers for attaching the guides will be installed.
    2. Install the hangers themselves necessary to fix the guides (for the latter, use a galvanized profile or timber).

    3. In appropriate places, cut small holes in the insulator (foam or EPS) for hangers.

    4. Next, secure the insulation boards using the same mounting foam.

    If the insulation weighs too much, you can use dowels for fastening. Blow out the cracks with foam. Otherwise there are no significant differences.

    Finishing features

    In most cases, balconies are lined from the inside with clapboard or profile, but plasterboard is also used, followed by wallpapering. PVC panels are also used for cladding. Concerning exterior finishing, then it is better to entrust it to professionals, especially if your apartment is located higher than on the ground floor.

    Important information! It is forbidden to take there central heating, so if additional heating is required, you can lay a film “warm floor” under the linoleum.

    You can also install an outlet on the balcony to which you can connect electric heater. The described room is small, so heating will take a minimum of time. We also note that the double-glazed window weighs quite a lot, so the remaining materials (including the insulator itself) must be of minimal weight. By the way, this is another reason why it is better to give preference to EPS or foam boards.

    Video - Instructions for insulating a balcony

    Now you know about the strong and weaknesses materials suitable for insulating a balcony, as well as technologies for laying polystyrene foam and expanded clay. Therefore, it's time to get to work! Moreover, there is nothing complicated here if you are armed step by step instructions and all necessary materials. If you do everything correctly, you will turn the balcony into a full-fledged living room with all the ensuing benefits.

    Balcony in modern apartment- enough functional room, therefore, such an issue as insulation and finishing of the balcony is important, and its solution should be approached very responsibly. Especially if you want to increase the total living space due to the balcony. Compliance with the basic rules of insulation and finishing will help turn your balcony into a cozy and beautiful room for relax.

    Basic rules for insulating a balcony

    Balcony insulation work, as a rule, begins with the dismantling of the previous finishing, old window frames and installing new double-glazed windows - this will significantly reduce heat loss and increase the room temperature by several degrees. Then you should start insulating the floor, walls and ceiling. Important! Before starting work on replacing double-glazed windows, you should decide on the material window profile(wood, aluminum or PVC profile) and further strengthen the balcony parapet using reinforcement. The PVC profile is the best option. It has a high level of thermal conductivity, is not susceptible to moisture and temperature changes, corrosion and rotting.


    Main types of windows:

    • with two-, three-, four-, five-chamber double-glazed windows;
    • with extended profile;
    • with hinged doors;
    • with a sliding or tilt-and-turn system.

    The window profile can be not only metal-plastic, but also wooden. Modern wooden frames significantly different from their predecessors - they are tailored to size, have a beautiful appearance, high-quality fittings and mechanisms similar to plastic models. However, wood is not an airtight material, so its use is more justified in regions with a warm climate. High-quality glazing not only retains heat, but also reliably protects the room from wind, rain, and dust. Therefore, you should choose not only the profile, but also the thickness of the glass. The optimal solution would be glass with an energy-saving coating, which has reflective properties and a higher level of thermal insulation.


    To carry out this stage of work, we recommend using the services of specialized companies, since without certain skills and experience it is difficult to install window profiles efficiently and, most importantly, correctly.
    The algorithm for insulating a balcony with your own hands includes:

    1. Clearing the area of ​​foreign objects.
    1. Dismantling old structures, strengthening the parapet (especially important for old buildings).
    1. Installation of a new window profile, heat-saving double-glazed windows.
    1. Laying electrical wiring, installing a heating system.
    1. Selection of insulating materials, insulation of floors, walls, ceilings.
    1. Decorative finishing of surfaces.

    If you do all the work yourself, you will need the following tools: drill, hammer drill, screwdriver, building level, square, tape measure, drywall knife, electric jigsaw.


    The main types of insulating materials for insulating a loggia or balcony

    The modern market offers a wide variety of materials with which you can perform high-quality insulation balconies or loggias, but the most popular are: polystyrene foam, polystyrene, mineral wool, expanded clay, foil polyethylene, isolon, penofol. The choice of insulating material directly depends on the operating conditions, base and number of floors of the balcony. For example, at high humidity, mineral wool cannot be used, as it is prone to the accumulation of water vapor, which causes damage to the coating and contributes to the formation of mold during operation. The best option would be to use polystyrene foam, penofol or isolon as insulation. Polystyrene foam, despite affordable price and ease of installation, has one significant drawback - rapid flammability, therefore it is preferable to use more modern insulating materials with high level fire resistance. Extruded polystyrene foam is a modern insulating material that is easy to install, durable and moisture resistant. Its only drawback is high price, which, by the way, is fully justified by ease of use and high quality thermal insulation. The choice of material also depends on the season of work, because some insulating materials change their performance properties under the influence of dampness or freezing temperatures.


    If the balcony is insulated in spring or autumn, consider high humidity, which complicates the process of gluing layers and has a detrimental effect on operational characteristics most insulating materials (with the exception of polystyrene foam, penofol and penoplex). IN in this case the main work needs to start from the top, because insulating the ceiling will allow work to continue even in the event of sudden rain. If insulation work must be carried out in winter (if the air temperature is not lower than 20 degrees), then special adhesives and adhesives should be used cement mixtures, which, unlike ordinary cement, do not freeze, but harden even at low temperatures.

    Important - polyurethane foam should also be selected taking into account temperature regime, since some of its types are destroyed by frost.

    Basic rules for floor insulation


    If you want to efficiently insulate your balcony - Special attention should be given to the arrangement of the floor. To complete this step you will at a minimum need: wooden slats, self-tapping screws, polyurethane foam, insulation. Insulation of the floor consists of leveling it, laying a waterproofing layer (with mandatory treatment of joints with sealant), heat insulation, pouring concrete screed(if necessary on at this stage a heated floor system can be installed) and finishing.Tip: if it is not possible to fill the screed, you can skip this step. Then you will need to lay special logs ( wood slabs), between which should be placed thermal insulation layer(for example, expanded clay or penoplex). The top of the logs is covered with chipboards or plywood, then you can begin finishing the floor. To insulate the loggia floor, you can use an inexpensive insulating material - expanded clay, which, in addition to its thermal insulation properties, raises the floor level, which is very convenient when expanding the living space due to the loggia. In addition, its use does not require the use of a waterproofing layer, it is sufficient to use vapor barrier film, on which expanded clay covered with a reinforcing mesh is placed. The tightness of the structure is ensured by filling cement mortar, which, when hardened, forms a strong flat surface. Linoleum, laminate or tiles can be used as flooring.


    The list of works at this stage includes:

    • cleaning the surface from debris and dust;
    • sealing cracks and crevices (using sealant, polyurethane foam or polyurethane mastic);
    • high-quality vapor and waterproofing;
    • installation of a wooden frame;
    • installation of a thermal insulation layer;
    • securing base boards;
    • decorative interior decoration.
    • Insulation of balcony walls

    Before you begin insulating the walls, you should treat the surface with a special antifungal solution and carefully seal all the cracks on the balcony. Polyurethane sealants and mastics, which have high plasticity and frost resistance, are most suitable for this purpose. Then you can begin installing the vapor barrier film (the joint seams are taped with special construction vapor barrier tape). Next comes the installation of wooden or metal sheathing and laying out the selected insulation (for example, polystyrene foam, penoplex). The final stage will be plating frame profile moisture resistant sheet materials(plywood, plasterboard) and decorative finishing walls. Please note - if the wall of the loggia faces the street, a double layer of insulation should be used. If penoplex was chosen as insulation, you should make sure that the joining seams of the layers do not coincide.


    Basic principles of ceiling insulation

    Ceiling insulation - important aspect, which cannot be ignored. Especially if you don’t have upstairs neighbors - in this case, in addition to insulation work, you should choose high-quality roofing material.

    Advice: before starting work on inner side It is recommended to apply a special soundproofing coating to the roof.

    In any case, the choice of materials for roof insulation depends on many factors - climate zone, wind direction, cardinal direction.
    The roof insulation algorithm includes installation:

    Ceiling insulation is carried out in the following sequence:

    1. Installation metal frame(suspensions).
    1. Laying a vapor barrier layer.
    1. Fastening the insulation (foam plastic, isolon, penoplex).
    1. Application of foil insulating layer.
    1. Finishing.


    How to avoid mistakes when insulating a balcony

    Please note that when performing any construction work You should strictly follow the technology and recommendations of the manufacturers. Even if you have certain skills, this is a complex multi-step process that requires compliance with all technological conditions. This is especially true when insulating a balcony with your own hands, because any mistakes will affect the final result. So, when insulating the “beyond the window” area, follow the order of layers - the vapor barrier is installed only after the thermal insulation layer, and not vice versa. Availability of vapor barrier - required condition, which reduces the risk of destruction of insulating materials under the influence of moisture. Replacement of double-glazed windows and installation of a heating system without internal insulation will not reduce energy costs and is an ineffective way to save heat.Use low-quality materials contributes to heat loss, so the choice of building materials should be approached as responsibly as possible.
    Excessive haste also affects the quality of insulation - non-compliance with technology, insufficient sealing of cracks with sealant, ignoring waterproofing rules, of course, affect the final result.

    Methods for additional insulation of a balcony


    If you plan to use your balcony as a living room or recreation room, you should take care of its additional heating. In order for the temperature to be comfortable even in severe frosts, it is necessary to install an additional heat source: a radiator, air conditioning or underfloor heating system. Please note: you can combine the heating method, for example, if an air conditioner is installed in the room, then on the balcony to maintain comfortable temperature It is enough to install a warm floor. However, if the apartment is heated using central or autonomous heating, batteries should also be installed on the balcony.

    Decorative finishing of an insulated loggia

    Properly done insulation and finishing of the loggia with your own hands will not only reduce heat loss, but will also save money. For decorative finishing of a loggia or balcony, the most popular are plasterboard and plastic panels. Moisture-resistant drywall- one of the best ways balcony finishing. It is easy to install and suitable for further decorative finishing (painting, plastering, wallpapering, tiling or artificial stone). Finishing with lining and decorative panels also has a lot of advantages. Their distinctive characteristics are: ease of installation (even a beginner can do the job), big choice colors, moisture resistance, frost resistance, durability, ease of care.


    The finishing procedure with decorative panels consists of several stages:

    1. Surface preparation: dismantling the previous coating, removing traces of mold (if necessary).
    1. Installation of a wooden frame.
    1. Fastening the panels (work is performed from the doorway, along the wall, outer side sheets are secured with special brackets).
    1. Installation of baseboards, window and door openings.

    Please note that the panels can be used for decorative finishing of the ceiling (in this case they are fixed not along, but across). Having studied the features of insulation of a loggia and balcony, you can independently carry out all the basic work, which will expand the living space of the apartment, creating comfortable conditions for relaxation, make a study or corner for handicrafts. Insulation and decorative finishing of a balcony is not particularly difficult, so all you need is the desire and availability necessary materials and tools.
