As a rule, bathhouses rarely have a usable underground, so the floors are often installed directly on the ground with a layer of insulation between the finished floor and the base.

Expanded clay can be used as insulation, which has good thermal performance and high mechanical strength. A floor poured over such insulation will last for many years without deformation.

Also, extruded polystyrene foam can be chosen as insulation, reliably protected by layers of screed and finishing coating from the high temperature inside the steam room.

Insulation of the steam room ceiling

You should also pay attention to insulating the ceiling of the steam room so that hot air is stored indoors for as long as possible.

In one of the publications we already touched on the issue of how to properly insulate a ceiling. It is also advisable to choose mineral wool roll or slab materials as ceiling insulation. Filling the floor with expanded clay is also quite widely practiced.

Quite often, bathhouse buildings are erected from bricks. When they are built by one of important stages Insulation of a brick bathhouse from the inside is considered. The fact is that walls made of this material cannot retain heat for a long time.

Materials used for insulation

After the walls are erected, the roof is mounted and the doors are installed, the interior decoration of the building begins. The insulation of a brick bath must be done so that an optimal microclimate is maintained in the premises for a long time and temperature regime. It also helps to retain heat inside the building. decorative finishing walls

Typically, insulation of a brick bathhouse from the inside is done with your own hands by installing a multi-layer heat-insulating structure. One of its layers is laid from slabs, and the other from roll materials, having a foil-based coating, since this type of thermal protection perfectly reflects infrared radiation and protects the insulation from negative impact humid air.

To perform efficiently this work, you need to know how to insulate walls in brick bath and how to insulate a bathhouse from the inside correctly.

Experts advise using the following materials:

• mineral wool in rolls or slabs;
• glass wool;
• peat or cellulose slabs with a porous structure;
• reed mats;
• slabs made of polyurethane or polystyrene.

It should be taken into account that polystyrene-based thermal insulation materials, like glass wool, do not have good heat resistance. For this reason, they should not be used when insulating a steam room in a brick bathhouse, in particular its walls and ceiling. To reduce heat loss through flooring, a layer of expanded clay is used as an additional heat insulator.

Insulation materials produced on the basis of foil have proven themselves to be excellent. As you know, materials such as foil film are expensive, so for interior decoration In bath rooms with a low degree of humidity, it is allowed to use kraft paper. The result is savings. For example, in a recreation room, cheaper materials can be used for insulation.

Thermal insulation of floors in brick baths

Insulation options that are suitable for baths under construction are not suitable for thermal protection of bath buildings in which an old bath is being overhauled. But the sequence of work in both cases has much in common.

When insulating a brick bathhouse from the inside, the scheme stipulates that work must begin with the floor covering. Thermal protection of the floor is necessary, since a person moves on its surface barefoot, which means it must be heated as much as possible.

Before insulating brick bathhouse from the inside with your own hands, you should create an air gap between the foundation of the building and the floor covering. This will ensure sufficient thermal insulation.

When creating a gap, support beams are installed at the base of the room, and expanded clay is poured into the spaces between them, the layer of which should be approximately 2 times the thickness of the walls in the building. Logs made of wooden beams, which are pre-dried and treated with antiseptics.

Plates of heat-protective materials are placed between them, and the gaps between the joists and the insulation layer formed during the work should be eliminated using polyurethane foam. Then you need to lay glassine on the floor, and make a flooring on top of it plywood sheets or boards. Install the main floor covering at the final stage.

Features of thermal protection of walls in baths

After completing the thermal insulation of the floor, they begin to create protection for the walls. Before insulating a brick bathhouse from the inside, in order to prevent the growth of bacteria, the walls are impregnated by special means. This procedure is required only for the treatment of certain rooms - these are shower rooms and steam rooms.

There are features regarding how to properly insulate a brick bathhouse (the walls in it):

1. To reduce the degree of heat loss, gaps between windows and walls are eliminated using polyurethane foam.
2. The frame on which the sheathing is mounted is constructed from wooden beams and fixed directly to the brickwork.
3. Not recommended for use at work metal profiles and suspensions, since they have the property of conducting thermal energy.
4. Mineral wool or polystyrene boards, used as insulation, are placed in the cells that make up the sheathing.
5. Thermal insulation material is fixed to the masonry with dowel umbrellas or special adhesives are used.
6. Before applying the thermal protection, bath walls made of bricks must be treated with a penetrating primer.

After completing the fixation of the main thermal insulation material on the walls, you need to lay a vapor barrier layer made of kraft paper, or foil film or other materials. Reliable vapor barrier of a sauna steam room is simply necessary.

You need to know how to properly insulate a steam room in a brick bathhouse, since especially damp room Kraft paper will get wet and soon become unusable.
For such places, foil-based film is best suited.

If necessary, a counter-batten can be placed on the sheathing beams, as a result of which a gap will appear between the outer sheathing and the vapor barrier layer. Then the clapboard is nailed to the counter-lattice.

In the case where the bathhouse has a large square area, its walls should be insulated on all floors in order to avoid significant heat losses during operation. If there is a loggia, it too must be insulated. In addition, to ensure the thermal protection of the building, it will not hurt to install high-quality entrance doors equipped with at least two sealing contours.

The procedure for thermal protection of the ceiling

It is impossible to eliminate heat loss in bath rooms without insulating the ceiling in them. This is especially important to do when they are located in a one-story building.

The sequence of work when installing thermal protection for the ceiling in a bathhouse is as follows:

1. Fiberglass is laid on top of the ceiling, placing strips of material overlapping. They are connected to each other using tape or adhesive tape.
2. A solution mixed from clay, chopped straw and river sand. The thickness of this layer should be approximately 30 centimeters.
3. On clay mortar lay a layer of polystyrene foam, and then pour it on top cement mixture about 10 centimeters thick.
4. To improve the thermal insulation properties of the bath structure, it can be added to the cement mass. foam chips, keeping the proportion 1:3, or even better 1:4.
5. Sheathing beams are attached to the rough surface of the ceiling from the inside, placing between them basalt wool in slabs.
6. On top thermal insulation product lay a film of foil, and cover it with clapboard on top, maintaining a 10-mm gap between the elements.

Given that correct execution by insulating the room from the inside, during its operation the loss of thermal energy will be minimized, which means that visiting the bathhouse will bring maximum pleasure.

When choosing which bathhouse to build - wooden or brick summer cottage, you first need to decide and understand some of the nuances of these building materials. A special feature of brick is the careful insulation of a brick bath from the inside, due to its high thermal conductivity.

During construction, a wooden bathhouse requires additional measures such as applying protective agents against fire, as well as waterproofing the load-bearing elements of the structure.

Unlike wood, brick buildings have fire-resistant and moisture-proof properties. At the same time, in order to improve comfortable conditions when taking hygienic procedures, insulating a brick bathhouse from the inside helps to increase the heating efficiency of the building by about 2-3 times. Next, we will consider how and in which rooms to insulate a brick bathhouse, as well as what materials are best used for these purposes.

Features of internal insulation of a brick bath

When building a bathhouse, it is important to know how and where, if possible, to insulate a brick bathhouse from the inside with your own hands.

The main elements of the structure that require insulation or thermal insulation from the inside of the bathhouse are:

1. Foundation around the entire perimeter of the building.
2. The flooring in all rooms is the same around the perimeter.
3. The ceiling, that is, the roof.
4. , both external and internal (partitions).

At the same time, insulating a brick bathhouse from the inside, its scheme as a whole does not represent any complex or particularly labor-intensive process.

More often internal insulation walls are carried out according to two common options:

1. By creating an additional second wall along the main one, that is, along the entire perimeter of the main brick wall and inside the room.
2. The recommended thermal insulation inside a brick building is also achieved by installing a double layer of insulation.

As for the insulation of other components of the bathhouse, here, as a rule, everything is almost standard, that is, today most thermal insulation materials are quite suitable for achieving these goals.

Materials for bath insulation

In order to insulate a brick bathhouse, you will need to purchase certain materials that in the classic way thermally insulate from the inside one or another of its constituent elements - foundation, floor, ceiling or walls.

So, for thermal insulation of the horizontal part of the foundation, as a rule, they use either expanded clay, since these materials are the most affordable and have all the necessary qualities to cover this element of the bathhouse. Vertical insulation of the foundation of a brick bathhouse, for example, with penoplex or polyurethane foam, is recommended to be carried out with the help of specialists, since applying them independently will cost the owner of the future bathhouse more than calling a specialist with a ready-made arsenal of everything necessary for such procedures.

It is recommended to cover the floor in rooms such as the dressing room and washing room with ceramic tiles with thermal insulation underneath, respectively. Schematically, this procedure can be briefly described as follows: sewn to the beams cranial block, on which a subfloor made of boards is mounted, then a layer of vapor barrier is laid, then thermal insulation material (expanded polystyrene or expanded clay) is laid on top, and finally it is placed on the resulting pie reinforced mesh, and all this is then poured cement-concrete mortar.

At the same time, after drying concrete screed the floor in a brick bathhouse is covered with waterproofing and then applied to it ceramic tiles. In the steam room and relaxation room, the floor covering must be decorated wooden flooring, in order to avoid the so-called thermal shock from the steam-heated floor.

A brick bath is made using basalt insulation, which is covered on top with special foil for baths. The boundaries of the joints in foil insulation and the foil itself are glued together with wide aluminum tape specially designed for this purpose.

As for the ceiling, it is insulated on top with mineral wool with mandatory double-sided waterproofing. Ceiling insulation of a brick bathhouse from the inside can also be done using fiberglass, 2 clay-sand layers (one layer of sawdust, and the other layer of vermiculite or its equivalent), as well as penoplex - laid on top of all these layers.

At the same time, in the steam room, it is again advisable to cover the ceiling with foil-coated fiberglass, since polystyrene foam releases substances hazardous to human health when heated strongly.

Other recommendations for insulating a bathhouse

If the insulation of a brick bathhouse inside, tested over the years and recommended by experts, is carried out mainly with materials such as mineral wool, expanded clay, vermiculite, penoplex, polyurethane foam, basalt insulation, fiberglass and so on, then we should not forget that there are other bottlenecks in which small but heat losses also occur.

Of course, these places are mainly either door or window openings, usually external. In this regard, it is not advisable to lay large windows, facing the street or courtyard, as well as very high doors. At the same time, it is recommended to place window openings as low as possible, and front door must be equipped with a threshold.

In order for the insulation of a brick bathhouse inside to be more reliable, it is preferable to install triple-glazed windows on the windows, and choose doors made of wood with insulation inside, or from heat-resistant, shockproof, durable glass.

Another small nuance that should not be neglected when building a brick bathhouse is the implementation of local protective impregnation bricks from exposure to harmful bacteria. It is recommended to perform this procedure mainly in rooms such as steam rooms and showers.

It is equally useful to know several reasons why it is not recommended to carry out external insulation of a brick bathhouse. One of them is an undesirable and very expensive pie of insulation on both sides of the brick. By insulating the walls of a bathhouse from the outside, the consumption increases not only in building material, but also for fuel. The other is significant losses in heating cold bricks in winter.

A simple calculation based on the laws of physics will help you avoid the formation of condensation on the ceiling in the steam room: thermal insulation for the ceiling should always be proportionally thicker than for the walls.

Summing up

Because private bath, whether it is made of brick or wood, and is used periodically, it makes no sense to maintain a constant positive temperature in it. Therefore, as a win-win option, if the bathhouse has a brick frame, it is recommended to carry out all measures to insulate the premises inside.

Thus, proper installation of insulating brick walls with layers of insulation from the inside will give good savings in the cost of heating the premises. In turn, this means that the thermal insulation material must work according to the retention rule warm air in a confined space.

If all the measures for insulating the surfaces of the building were carried out correctly, then such a brick bathhouse during operation will retain the maximum heat received from the burned firewood inside, and its visitors will ultimately receive incomparable pleasure from staying in it.

To figure out how to insulate a brick bathhouse from the inside, you need to understand the performance characteristics of the wall material. Compared to a wooden bathhouse, a brick structure has the advantage that it does not require any fire protection treatment or waterproofing. A brick bathhouse has only such a drawback as low thermal conductivity. This prevents the bathhouse or sauna room from warming up well, and the heat is not completely retained. To increase thermal insulation properties buildings, it is possible to insulate brick walls.

In order for the bathhouse to be warm, it must be built with one and a half or two bricks.

If we're talking about Regarding a private bath, it does not make sense to maintain a constant temperature above zero from the inside all the time. But due to periodic use in the cold season, the walls can freeze through, and when trying to flood the bathhouse, all the heat is spent mainly on heating the stone. When insulating the outside, the brick hardly heats up; it is covered only by the lining, so much more resources will be spent on heating than could be the case.

Thermal insulation of the walls of the bathhouse from the inside helps reduce fuel consumption. When installed correctly, the heat-insulating material does not release heated air outside, and it is stored indoors.

Construction of an additional wall

You can insulate a brick bath from the inside by building an additional wall. The material used for this is timber, which, according to its characteristics, is quite heat-saving and does not emit components hazardous to health.

Installation of insulating pie for bath walls is carried out according to the following scheme:

1. A sheathing is placed on the bricks.
2. Waterproofing is attached to the installed frame.
3. A timber wall is being erected.
4. Another crate is placed on top.
5. The beam is covered with fiberglass, which is fixed to the sheathing with a stapler. In the gaps of the sheathing, the fiberglass fabric should not be stretched. An overlap is made, which will subsequently make it easy to place the insulation.
6. Tile insulation is inserted into the gaps between the sheathing.
7. In order to create a barrier for internal steam, the insulating material is covered on top with foil or film vapor barrier.
8. Lastly, the lining is hammered on.

Regardless of which insulating material is chosen, its thickness should not be less than ten centimeters. You just need to pay attention to whether the insulation releases toxic substances when heated.

Fiberglass or basalt materials that are not exposed to moisture are considered optimal. This could be, for example, penoplex - at elevated temperatures it performs better than polystyrene foam, and also has self-extinguishing properties. But you need to be careful when using polystyrenes to insulate a brick bath - if they heat up too much, they can become charred, which leads to the release of harmful substances. It is better to use basalt materials in the bathhouse.

Two layers of insulation

When considering insulation options, sometimes the best solution may be to create a double insulating layer, that is, instead of beams, they put additional insulation 10 cm thick.

The design of the wall insulation cake will look like this:

• brick wall;
• waterproofing layer;
• sheathing;
• insulation material;
• waterproofing layer;
• another lathing;
• fiberglass;
• insulation material;
• vapor barrier layer;
• lining.

The total thickness of the insulating cake is approximately 22 cm. One of the layers heat-insulating material Those closer to the brick wall are better lined with extruded polystyrene foam. This material is not afraid of moisture and will not absorb external vapors. The inner layer of insulation must be selected taking into account the characteristics of the building being repaired. All bath rooms, with the exception of the steam room, should be covered with penoplex - foam material with a foil layer, which will become a barrier to water vapor.

For the steam room choose better materials made of basalt, and cover the top with special foil for the bath. So, when the air is very hot toxic substances stand out a little less. Seal the joints of the material with aluminum tape.

Why insulate the foundation of a brick bathhouse?

It is also necessary to perform thermal insulation of the bath floor. But measures to insulate bath floors lose their meaning if the foundation is not protected from the outside. In the bathhouse, the floors are affected by high humidity and the difference in room and ground temperatures. Therefore, before the floors are installed, the underground floor should be filled with slag or expanded clay. There is no underground floor in the baths, so it needs to be filled with insulation. interior space foundation.

In a structure such as a bathhouse, the foundation can become a powerful conductor for cold air - it is made of materials that do not have heat-saving characteristics.

When building a bathhouse, the top of the foundation is waterproofed with roofing felt or roofing felt to protect the brick from moisture from the soil. But this is rarely enough. It may be necessary to provide external insulation for all foundation walls. This helps to increase the degree of heat conservation of bath floors and prevent shrinkage and movement of the foundation.

When choosing a material, you must first of all be guided by your construction capabilities and the state of your wallet. It is advisable to draw up work plans before starting to install insulation materials. For example, choosing polyurethane foam will cost more financially than polyurethane foam, since the insulation is applied using special equipment. But installation will be carried out in just a few hours, the coating is very durable, without joints. There are no loopholes left for cold to penetrate inside the foundation.

Material such as penoplex is produced in the form of slabs. They are glued to the foundation walls glue mixture or special mastic. Any owner of his own bathhouse can do this work independently. But this type Installing insulation will take much more time - the slabs must be well joined, the seams must be well sealed, and some - for example, in the corners - it is better to blow out with foam.

Insulation from the inside is an inevitable event for most types of baths. It allows you to spend less fuel, warm up the steam room faster and better. Properly done insulation protects the walls of the bathhouse from fungus and rotting, and extends its service life. In this article we will select inexpensive and safe types of thermal insulation depending on the material of the bathhouse walls, and consider how to install them correctly.

• Insulation of bathhouse walls from the inside: selecting insulation;
• Insulating a bathhouse from the inside with your own hands: from the ceiling to the floor;
• Do-it-yourself insulation of a brick bath from the inside;
• Insulation of a bathhouse made of blocks from the inside
• Insulation wooden bath from the inside

Insulation of a bathhouse from the inside: materials

TO different rooms baths are presented different requirements, we will focus on the steam room and washing room, the features of which are high temperature and high humidity. Also, the insulation is selected depending on the material of the bath walls.

But, regardless of the material of the walls and the purpose of the room, the insulation must be:

• Non-toxic so as not to cause poisoning when exposed to high temperature;
• Not hygroscopic, so as not to absorb moisture;
• Resistant to high temperatures and steam;
• Non-flammable;
• Maintaining its shape even after several years of extreme use;
• Resistant to fungi and mold;
• Sold at a reasonable price.

Bath insulation

Insulation	In what room is it used?	Note
Natural materials: rolled jute, felt, insulation made from reeds and sawdust, moss, tow, etc.	Dressing room, rest room.	Natural materials ignite at high temperatures, so they are not suitable for steam rooms and washrooms. But materials made from jute and flax are the best inter-crown insulation chopped bath. There are excellent modern roll insulation from natural materials, but they are very expensive, so they are practically not used for insulating baths.
Mineral insulation.	They can insulate any bathhouse. Most often, slab insulation boards (mats) that are easy to install are used.	They do not rot, last up to 30 years, are fire resistant, and inexpensive. Most Russian baths are insulated with these materials.
Polymer materials	FORUMHOUSE craftsmen do not recommend it for insulating a steam room.	Polystyrene foam is an excellent heat insulator, but it is flammable, and at high temperatures it releases substances harmful to humans. You cannot use polystyrene foam in the steam room.. Extruded polystyrene foam or penoplex is considered a safe material (it is used to insulate the bathhouse of Russian polar explorers in Antarctica). But FORUMHOUSE experts do not recommend using this material in a steam room.
Insulation based on aluminum foil.	It is used in accordance with the manufacturer's recommendations for a specific room.	The operating principle of such insulation is the effect of a thermos, the reflection of heat from the walls and ceiling due to foil. Some types of foil insulation are produced specifically for steam rooms and other rooms with high temperature, others begin to release harmful substances when the temperature rises. Foil in the bathhouse is used as a vapor barrier.

Insulation of the bathhouse ceiling from the inside

The bathhouse is insulated from the inside in the following order: ceiling - walls - floor. The main part of the heat in the bathhouse is lost through the ceiling, so

The thickness of the ceiling insulation is twice the thickness of the wall insulation and is at least 10 cm.

Nomad

We hang at least 10 cm of insulation under the black ceiling. I really don’t recommend basalt wool, glass wool and polystyrene foam in the steam room. The insulation can be hung with lacing. Then foil, gap along the slats and lining.

Regardless of the material of the walls of the bathhouse, the ceiling is insulated in the same way.

When insulating ceilings, foil is mandatory.

Insulation of a frame bath from the inside

For insulation frame bath Rolled mineral insulation is most often used.

The thickness of the insulation depends on the type of operation of the bathhouse: if you plan to heat it only in the summer, a layer of 5 cm is enough; if you plan to heat the bathhouse all year round, the insulation layer should be 10-15 cm (depending on the climate zone).

To insulate the walls of a frame bath from the inside:

• Insulation is placed in the interbeam space of the structure;
• The next layer is vapor barrier (foil);
• Ventilation gap;
• Sheathing.

The photographs below show how KochevniK insulated his frame bathhouse. Insulation – basalt wool.

Insulating a bathhouse from the inside with your own hands: step-by-step instructions.

Foil acts as a vapor barrier, so it is important that there are no even the slightest holes or damage in it, and that all joints are well taped with high-quality tape. The tape is always sold together with foil, and its quality must be checked in the store (glue the tape to the foil and try to tear it off).

Insulating a bathhouse from the inside with your own hands: log house

Insulating a chopped and well-caulked bathhouse from the inside would be a tragic mistake. This is not only pointless and destructive for the walls, it contradicts the very idea of ​​a chopped bathhouse.

Log houses for baths are made for two reasons:

1. To get classical Russian steam bath, which takes a long time to heat and maintains the required level of heat and humidity for a long time. It is the tree that accumulates heat and moisture and gradually “gives it away”. In this case, the inside of the bathhouse cannot be lined; will also have to come to terms with high consumption firewood
2. For the image. No bathhouse looks as cool in appearance as a chopped one. But I often don’t want to waste time and firewood; I want the bathhouse to be heated in an hour, so insulation, vapor barrier and clapboard cladding are done. The log house works only as an external frame; the meaning of the material is lost. In this case, it is cheaper and more correct to build a frame bathhouse.

It happens that a person already gets ready sauna from a log house, and for various reasons it can be cold. Such a bathhouse can be insulated, but only from the outside.

The pie looks like this:

• insulation;
• wind protection;
• vertical sheathing to create ventilation gap;
• outer skin.

And you can put foil on the inside and line it with clapboard, not forgetting about the ventilation gap.

• We put foil on the beam and fasten it with a construction stapler;
• We seal ALL joints with foil tape;
• We fill the vertical slats with a thickness of 1-2 cm;
• We fill the lining horizontally, leaving gaps at the top and bottom for air circulation.

In a chopped bathhouse, only the floor and ceiling are insulated!

If the ceiling of a chopped bathhouse is made of thick boards, it is not necessary to use insulation, but then the following is poured onto the ceiling in a cold attic:

• ash;
• sand;
• expanded clay (it is preferable that the granules be different sizes);
• clay coating.

Insulation from the inside of a brick bath

Brick is not the best suitable material for the construction of a bathhouse, but if there is a brick factory somewhere nearby, then brick bathhouses begin to grow like mushrooms. Due to the high thermal conductivity of brick, such a bathhouse requires insulation without fail. Insulation is carried out only from the inside, and to make the bathhouse look cool from the outside, decorative jointing is done.

Typically, the pie of an insulated wall of a brick bath looks like this:

• brickwork;
• waterproofing,
• insulation;
• vapor barrier;
• sheathing

Waterproofing between brickwork and insulation is optional: if the walls are built correctly and waterproofed from the foundation, they will not become damp. If there is no confidence in the walls, then it is better to do waterproofing.

Insulation on brick walls The bathhouse is attached to the frame.

S4sha FORUMHOUSE Member

We build a frame on the wall from 100x40 timber with insulation width increments, fill it with insulation, lay a vapor barrier, sew on 20mm slats and cover it with clapboard.

Our user S4sha’s bathhouse is made of half a brick, but it steams just fine even at -30. Its walls are insulated like this:

• mineral wool;
• vapor barrier (in the steam room - foil);
• ventilation gap;
• lining.

Insulation thickness – 50 mm.

Insulation of a bathhouse made of blocks from the inside

For the construction of a bathhouse, durable and moisture-resistant blocks of expanded clay concrete are preferred. The insulation of such a bathhouse is thought out at the stage of its construction. The most important thing here is to remove the icy mass of concrete from the heating circuit. There is a technology promoted by our user ZYBY, which allows you to solve this problem by constructing a frame-wall from boards with an indentation from the walls of the bathhouse. It is suitable for insulating all baths with stone walls.

To ventilate and dry the space between the frame and the walls, several vents are made in the walls of the bathhouse, at the top and at the bottom outside. The vents are closed while people are steaming in the bathhouse; the rest of the time they are open for drying.

Insulation cake for steam rooms and washing rooms using this technology:

• concrete wall with vents;
• insulation on the frame-wall (with indentation from concrete wall);
• frame-wall;
• foil;
• finishing 50th unedged board(aspen, linden or cedar) to get solid wood in the steam room.

With this approach, there is no need to heat the ice walls. And the insulation will dry out between steaming sessions.

But many owners of a block bathhouse insulate it from the inside traditionally:

• concrete wall;
• insulation (attached to the frame);
• foil;
• ventilation gap;
• lining.

Insulation of a bathhouse made of expanded clay concrete blocks from the inside.

Such a bathhouse needs insulation from the outside as well.

Bathroom floor insulation

Precious bath heat it also goes through the floor, so it also needs to be insulated. To insulate the floor in a bathhouse, it is recommended to use expanded clay as the lightest and most environmentally friendly material.

Expanded clay is poured between layers of concrete floor as follows:

• pour the first layer of concrete;
• wait until it hardens completely;
• expanded clay is poured (layer thickness - 10 cm);
• install reinforced grating.
• pour a layer of concrete;
• make a cement-sand screed.

Summing up

Good bath - warm bath. And so that it warms up well until desired temperature, it is necessary to choose the right thermal insulation and insulate all structural elements.

The bathhouse is also insulated from the inside:

• Windows, doors and all openings - with natural sealants;
• External door– good natural materials.
