How to insulate the loggia from the inside

Loggia could well be called an additional room in the apartment, but, unfortunately, many its are used only in the summer, since it initially has no thermal insulation, and there are no heating batteries.

To know how to insulate a loggia from the inside, you need to consider different methods and materials that are used for this process.

Immediately need to note that the heating batteries installed in the apartment, take out on the balcony or loggia is prohibited. Therefore, the , will have to deal with other variants of bringing the loggia to the state of a full-fledged living room with the help of various heaters.

Thermal insulation materials used for insulation loggia

If earlier the store assortment of insulation materials was small, today their is on sale quite a large number.allows you to choose the right one depending on the planned thermal insulation system and climatic conditions in the region.

Mineral wool

Mineral wool - is a traditional heater, time-tested. It has not lost its popularity and today, especially as in recent years this thermal insulator is modernized and manufactured in a variety of forms.

Mineral wool can be fiberglass, stone and slag. It is produced in mats and rolls having a thickness of 20 to 200 mm and various dimensions. This material is plastic enough, so it is very convenient to work with it. In addition, cotton can easily be cut with an ordinary construction knife.

Very important its properties is low heat - and acoustic conductivity, so cotton wool extinguishes sounds well and keeps internal heat in the room.

However, it must be remembered that when working with this heater, should be provided for protection for the respiratory tract, eyes, facial skin and hands from the microscopic particles that the separates from the material. It is especially necessary to work with glass wool, since its invisible particles can dig into the skin and mucous membranes, irritating them and causing itching. The least harmful in work is basalt stone wool.

Foamed polystyrene( polystyrene)

Foam - is also a commonly used material, as it is affordable and holds heat well in the premises, and it is easy to mount to relatively flat surfaces.

Polystyrene is an excellent insulation and soundproofing, it lightweight in weight and has a smooth surface, so if properly installed, it can even even out the wall.

The material is available in different thicknesses - from 20 to 200 mm, and it can have different density - , this allows you to choose the right option. It is necessary to know that the higher the density of the foam, the worse the thermal insulation qualities, but the material with a high density is easier to install and fasten, and it also withstands high loads.

If foil foil is covered with more dense material, for example plywood, it is better to choose a lower density - heater, it will better retain heat and will soundproof the room.

Provided that the foam should not only insulate, but even level the surface, you must choose the option with the highest possible density, and is better to use extruded polystyrene foam.

Extruded polystyrene foam

This type of heater in its chemical composition, in principle, is an analog of ordinary foam, in its manufacture is used a completely different technology. It is extruded, which helps to achieve a high density of the material. Such a heater often covers the bulk of the floor, and it is well leveled and holds the surface. Unlike conventional expanded polystyrene, extruded is almost not subject to deformation under the mechanical action of -, even when walking on it, it does not blot out, so it is often used for top flooring.

foam foam. The is produced in different thicknesses, and sheets having 20 mm or more usually have a special nt for and join the panels in a single plane without slits.

Such material can be cut with a construction knife, thanks to the lock part, it is easily stacked, sheets are usually fastened together by means of "liquid nails" or mounting foam.

The advantage of expanded polystyrene over conventional foam is not only in its density, but also in low combustibility.

I must say that this material is not cheap enough for the price, but for the floor of the loggia it needs very little, so you can afford it.

Polyethylene foam

This material is produced in mats and rolls. It can have different thicknesses - The thinnest 2mm roll of foamed polyethylene is used for laying under the laminate, and the thickest, up to 20 mm, is used both as a stand-alone insulation or in combination with other materials.

The most effective foamed polyethylene foam having a foil coating( its still is called heat reflector ), since it is really capable of reflecting the heat flow in to the direction - in the room, keeping it indoors. In order for the material to work properly, it is installed or laid with a foil side to the side of the room.

Polyethylene foam in mats is also used for insulation of walls and floor, but less often than roll material. Basically it is used for making rugs of different thickness for sports and children's games.

Preparing a loggia for insulation work

You can determine the insulation only after the insulation method is selected, but before talks about its methods, you need to know how to prepare the room for further processes. Which would thermal insulation technology has not been selected, the preparation of the loggia is the same. Its needs to be installed in order to prevent the moisture from penetrating the heater through cracks and crevices, which will start to deteriorate from this , lose its properties, and its functionality will come to none, and means , all work will be donein vain. Therefore, , you should not neglect the preparatory measures or save on them.

The preparation of walls, ceiling and floor passes in the of a particular sequence.

1. The first step of is the cleaning of surfaces from cement outgrowths, old paint and other protruding elements that will interfere with further work. It is necessary to remove weak detached or crumbling areas to "healthy" concrete.

2. Then, a thorough cleaning of dust and debris from the floor surface is carried out. Dust must necessarily be collected by a vacuum cleaner, since it is necessary to detect cracks of different sizes in plates and walls.

3. After cleaning, you can proceed to work on sealing various types of holes, slots on the joints of plates and small cracks.

• Large and small cracks widen, cleaned, if necessary, wetted with water and filled with sealant or cement repair mortar.

• The slots between the slabs must also be expanded, should be sprayed with with water from a spray gun and filled with foam.

• mounting foam. In addition to these flaws, potholes and chips of - can also be found in concrete slabs, too. They will not interfere with the evenness of the anchorages, but condensation may accumulate in them during temperature changes. For their alignment with the common surface of , cement mortar with PVA adhesive is suitable.

4. After drying of all the cracks, the surpluses of frozen foam and sealant are cut off, and then all surfaces are covered with a primer. This composition will strengthen the surface, will become a protection against the occurrence of mold.

Waterproofing surface

Next, it is necessary to conduct waterproofing works of the floor and the lower part of the walls, to the height at which the finishing floor covering will be raised.

Waterproofing is carried out in different ways, and from them it is possible to choose an acceptable one for execution:

• Laying of roll-on waterproofing materials - is most commonly chosen for ruberoid. It is glued to the bitumen mastic heated by the burner. Today, an improved ruberoid is produced, which has a higher elasticity and a special adhesive layer of mastic, which is also heated by the burner.

• Impregnation with special penetrating compounds - this kind of material is used on concrete surfaces. If the floors are covered with tiles, then this method of waterproofing is not suitable for .

This kind of waterproofing is applied to several layers of , each of which penetrates into the thickness of the slab a considerable depth, crystallizing inside and covering all fine pores in the concrete.

Apply the compound to floors and walls very carefully, wearing gloves, to avoid getting burned.

• For floor tile , flooring is suitable for liquid rubber, which is applied using a wide brush on narrow surfaces and with - roller on large planes. For this, sometimes the composition is poured in separate puddles and distributed by a roller.

The liquids applied on the floor and walls form film, which reliably protects the log deck from moisture penetration from the outside.

• More one way waterproof concrete coatings - is a waterproof plaster compound. They are applied with a brush or spatula, leveling on the surface.
• " People's way" can be called covering the floor and walls with a thick oil paint. This method is better than the is suitable for tiled walls, as the poorly prepared concrete surface will quickly its absorb .

Special acrylic-latex paints can be used for the concrete surface.

• An affordable way of waterproofing is laying a thick polyethylene film . Its is laid on the floor with set on the walls, to the height of the of the future floor. It is very important to properly lay the material in the corners of the - loggia, this should be done so that the film forms a kind of capacity , which will protect the heater. On walls, the film is fixed with a construction tape.

Any of these methods will protect against moisture penetration into the loggia room, and means - and from the risk of formation of black mold, which is very difficult to combat.

How to insulate the loggia from the inside - installation work

After the final drying of the waterproofing, you can go directly to the process of insulation.

Thermal insulation of the loggia with of the battens on the walls, the ceiling and the floor. - is the most common and probably the most convenient method today. It is quickly and easily implemented if the surface of the room and the necessary materials are prepared in advance.

battens Usually the insulation of the loggia starts from the ceiling, but it can be done from the walls or the floor, each master decides for himself, the main - perform the work of the qualitatively.

Thermal insulation of ceiling

• Thermal insulation work on the ceiling is carried out in different ways, depending on the insulation chosen. But first of all, it is best to fix to its entire surface a thin foam polyethylene with a foil surface - , this will become a good substrate for the crate and a layer of the main heater.

before fixing the lath. Foam is fixed to a double-sided building scotch or to the universal glue "Moment" - it is dotted on the ceiling and the insulation is pressed on top. A sheet of foam must be wrapped on the walls on the 150 ÷ ​​200 mm - this bend will be an additional insulator for the joints of the ceiling and walls.

As further on this layer of insulation will be installed lath , it needs to be fixed so that it lasted up to its mounting.

• Next , on top of the insulation material is mounted crate . Its can be made from a wooden bar or a galvanized metal profile, which is commonly used for gypsum boards.

Both crate well is suitable for laying between its elements of mineral wool or polystyrene. Elements of the are fastened at a distance from each other, equal to the width of the heater, so that it will fit tightly between them. When using Minvats , this interval can be reduced by 30 ÷ 50 mm - this will be even better for the most dense installation.

• The next step is the insulation. Mineral wool - is a plastic material, so tight stands up between the bars. The foam plastic has an rigid structure, so sometimes small gaps form between the elements of the crate and the heater. They must be filled with a mounting foam, in order to avoid the formation of cold bridges.

• The heater closes on the guide rails with gypsum boards or with a wooden lining.

Another way to insulate is to fix the extruded polystyrene directly to the concrete ceiling.

Mount the insulation materials to the ceiling with special plastic fungi. For these fasteners through the heater in the concrete wall holes are drilled, is installed in it fungus, and then the is carefully clogged with a plastic nail.

Warming the floor of the loggia

The floor of the loggia is also insulated in various ways by the -. This can be a dry screed, a floor raising with the log or simply the flooring of extruded polystyrene foam on concrete. The latter way will not give the proper effect, it just helps to make the floor not too cold.

• Thermal insulation with logs - is the most applicable and effective method.

ladders can be laid on concrete, or be raised to the desired height with the help of different - devices. For this, metal holders, studs, adjustable self-made sticks are used.

Metal holders are capable of raising the floor rails on the defined by the height, and if the of its is sufficient to solve the insulation problem, then this is a very good variation of the nt for the lug mount.

If the loggia has a standard width, then it is sufficient to install three rows of logs on it.

The holders are attached to the concrete base, then on each of them the heater is put on. In combination with these fasteners, one type of mineral wool is usually used. From it cut a square piece, in it make two holes through which a heater and put on the rack.

When all the logs are fixed in the holder and aligned horizontally, the main heater is laid on the entire floor surface. Then it is best to lay still one layer of mineral wool - it should be raised almost to the level of the lag.

The vapor-insulating film - is laid on top of the insulation, is attached to the lags by brackets.

Plywood with a thickness of 10 mm is fastened to the logs. All the cracks between the wall and the plywood are fixed with a mounting foam. After drying, it is cut off. And on top of the plywood is laid decorative coating.

Another option for the can be metal or plastic adjustable stands, which easily are installed at the desired height. They are convenient in the event that the floor on the loggia is not quite level, and with the help of the lag supports it will be easy to set it horizontally. Using such devices, you can abandon the leveling screed.

The stands are fixed and fixed with lugs, and only then they are put and screwed to the floor and leveled in height.

Other work on the placement of insulation and coatings are carried out in the same way as installation using metal holders.

If you can not find the above-described supports, or if their installation seems too complicated, and you need to raise the floor to the balcony door threshold level, the is suitable crate , mounted on supports made of the same bars.

To exhibit this design, with floor irregularities, is much more difficult, but it is possible to do this. Such lath must necessarily be attached to the walls of the loggia.

The rest of the work is done in the same way as in the two previous cases.

If does not have it is planned to build an additional room, and is insulated by its so that cold air does not penetrate the apartment, then you do not need to raise the floor to the threshold level. It is sufficient that the insulation is laid on the height of the log, fixed on thin polyethylene foam, laid on concrete.

In this case, the logs are drilled through and fixed using anchoring fasteners. Between log , and mineral wool or polystyrene is laid along the walls, it is closed with vapor barrier and plywood.

• Recently, more and more often for insulation use the bulk floor( dry screed), which consists of expanded clay and gypsum-fiber slabs. If necessary, such a floor is laid in two layers.

In order for the to install such insulation, temporary insulation beads are installed on the waterproofing material to level the filled mixture. In addition, on the walls, on the height of the future screed, fixes the damper tape, which will protect the coating against deformation at any temperature differences.

before filling it. Most often, this floor is leveled on the loggia by parts because of the inconvenience of working in the cramped space. Aligning one section and covering it with with gypsum fiber panels, you can proceed to the next. The alignment process must be constantly monitored using the building level.

Plates begin to stack from the corner of the loggia, using the grooves available on them, which are smeared with "liquid nails" and superimposed on each other, forming an integral coating.

When the panels are laid completely, the gap between them and the walls is filled with a mounting foam.

The surface is enough rigid , and on it it is possible to lay any decorative coverings, including strengthening the infrared with film.

• It is forbidden to put water central heating on a balcony or a loggia, but it is possible to organize an electric heating of the room. The best and most economical variant nt pr and this - immediately provide for the installation of the infrared heating film .

The film of the infrared floor must be laid on the rigid insulated surface. However, if is laid on its on a concrete foundation, then it is impossible to get the proper effect from of its work, . It will function properly, there is the necessary condition that the heat from film be stored and sent toThe side of the loggia, and not left in the concrete floor and walls.

For this the film is laid on the already insulated and the leveled floor, under the decorative coating. For more information on film mounting technology for floor heating, please see the corresponding page of our portal.

Thermal insulation of the walls of the loggia

The process of wall insulation is carried out in the same sequence as the rest of the premises of the loggia. It can also be performed in various ways, using the curtain or the hardener installation, with its attachment to the wall with glue or mounting foam.

• The installation of a penoplex is simple enough if you pre-prepare the with the size of the panel required by the .

On the reverse side of the heater applied adhesive, and the panel is pressed against the wall - so all vertical surfaces are faced. For reliability fixing panels with plastic " fungi "

• The most common thermal insulation - with the use of of the battens, because by applying it, any thermal insulation material can be used.

The is made of bars or metal profiles.

It is recommended, before installing the crate , on all surfaces to fix foamed polyethylene foam, which will greatly enhance the efficiency of any insulation material.

• log room. is fastened on top of this substrate crate. Its guides are placed at a distance from each other, equal to the width or length of the insulation mats.

• Further, the selected insulation material is laid or installed.

• It is recommended to cover the insulation with with film, which is fastened on wooden blocks with staples, and when using metal , the can be fixed on the upper and lower edges.

The final step of the insulation is the wall covering with a decorative material, such as a lining, or a base for painting or plastering, for example, plasterboard.

Thermal insulation with polyurethane foam

This method is more often used for insulation of roofs from inside and walls outside in private houses. But, thanks to the speed and convenience of installation, today this way is insulated by balconies and loggias.

Polyurethane foam is sprayed on the walls with the help of special equipment, and such insulation companies are engaged in.

However, before they are invited to to spray such a heater, the walls must be prepared by making crate on them. It will be a kind of skeleton for sprayed and expanding heat insulator, as well as for fixing decorative finishing material.

The advantage of this method of insulation is that when spraying the material, expanding, covers all the cracks, making the surface absolutely not purged, without bridges of cold. Polyurethane foam covers not only the walls, but also the ceiling and the floor.

Design solutions for logging

I would like to show several options for insulated loggias. Perhaps, having started ss pr eurascheniya cold room in the useful area, someone will be inspired by one of the ideas developed by designers.

In this case presents a standard loggia with a small footprint, transformed into a cozy lounge. Here you can retire with a book or laptop and go deeper into reading. If a large family lives in an apartment, usually every its member is engaged in a favorite business, and sometimes it is difficult to find a cozy place to sit in silence. Insulated loggia will be ideal for this.

In such a room you can place a small TV and enjoy your favorite programs or sit with a needlework, snugly picking up on a comfortable leg chair. The main thing is that appears extra space , which can serve as to all members of the family alternately for practicing the favorite thing.

This option is suitable for apartments in which the door to the loggia is arranged in the kitchen. In this case, it can become a canteen, especially since in the main kitchens in the apartments are quite small.

If the owners of apartments like to spend parties often, the sill of the loggia with ease will replace the bar rack.

Here you can also arrange a romantic dinner. Evening city, which offers a wonderful view, and a pleasant summer air will create the necessary mood for this. In winter it's nice to sit at the counter, sipping coffee and looking at the wide panorama of the opening outside.

Glass doors-compartments, installed between the kitchen and the loggia, will help to unite or delineate the rooms, depending on the need.

In this version, the loggia was combined with the living room, and the wall, previously serving as a separating element between the two rooms, became unifying, as it was converted into a comfortable table.

The area of ​​the former loggia in such a layout can be used as an office with a comfortable desk, as well as hobbies, when one does not want anyone to interfere.

And, of course, the combination of a loggia and a room will increase the total space by opening a large window. The room will be more illuminated, which will help save on electricity.

Additional living space can be adapted to different activities, for example, make a log garden, workshop or computer room on the loggia. Therefore, if the apartment is equipped with a loggia, but it

is not yet insulated, it is urgent to get down to business and expand the area of ​​your home for account not used by functionally.
