Insulating a sauna with your own hands. Insulating the steam room from the inside step-by-step instructions. Steam room internal insulation technology

Today, before starting construction of a bathhouse complex, every owner should ask himself how to insulate a bathhouse from the inside. The construction market offers dozens of options. The main thing is not to get confused and choose such insulation for a bathhouse so that it meets construction requirements.

Principles for choosing insulation

When buying material, you should pay attention to the most important signs of an effective product:

1. environmental friendliness;
2. maximum degree of moisture resistance;
3. resistance to harmful microorganisms;
4. the ability not to deform during long-term use;
5. thermal conductivity index: the higher it is, the better;
6. compatibility with building materials;
7. minimum moisture absorption value;
8. compliance with fire safety requirements, sanitary and epidemiological standards;
9. ability not to accumulate condensate;
10. ease of installation.

Types of insulation materials

Before you run around the shops and grab anything, you should understand the range of materials on offer.

Bath insulation can be organic or inorganic.

Organic materials

This includes a group of insulation materials that are made from natural raw materials:

• sheep wool or felt;
• jute;
• tow;
• heat-insulating materials from peat, reeds and wood shavings.

The main advantage of natural materials is environmental friendliness.

But insulating a bathhouse from the inside with their help has a number of disadvantages:

1. Natural thermal insulation for the interior decoration of a sauna is a labor-intensive and time-consuming process.
2. Natural insulation materials are short-lived and require regular updating.
3. Flax, moss, felt, tow are a favorable environment for the life and reproduction of insects, rodents and other harmful microorganisms.
4. They are suitable for dressing rooms and rest rooms, but are not suitable for thermal insulation inside hot rooms, even after additional treatment with fire retardants.
5. Purchase natural materials significantly “hits the wallet.”

Inorganic or synthetic materials

There is no need to talk about absolute environmental friendliness here. Unlike natural ones, they will last for decades and provide better thermal insulation. Synthetic bath insulation is easy to install and is resistant to high humidity and hot air.

Inorganic thermal insulation materials are divided into several types:

1.Polymer insulation

The group of these materials includes polystyrene foam, foam plastic, and cellular plastic insulation.

Polyfoam is easy to use to insulate the sauna ceiling. It does not absorb moisture, practical and easy to handle.

Foam glass has become a novelty in the construction industry, embodying the best properties of foam plastic and stone wool. The material can be carved with a knife and attaches perfectly to the surface.

Despite the advantages, it is not recommended to insulate the ceiling inside a sauna with polystyrene foam. On the one hand, it is considered a fire hazard. On the other hand, as the air temperature increases, the foam deforms and releases bad smell, vapors of a toxic substance - phenol.

If you still decide to use polystyrene foam, then it is better to insulate the walls of the dressing room with it from the outside.

2.Basalt insulation for baths

Made from mountain wood, the material is used in last years demand. It has a number of advantages:

• Not subject to combustion;
• Resistant to humid air;
• Does not deform under the influence of temperatures;
• Excellent sound and heat insulation;
• Service life up to 30 years;
• Does not cause any difficulties during the installation of finishing.

As for the disadvantages, there are none except for the cost of the material.

3.Mineral wool

The main difference between the technology for producing mineral wool and the production of insulation from basalt fibers is the use of inexpensive industrial waste.

This has a positive effect on the price of the material, but negatively on the mechanical strength of the insulation. Therefore, be extremely careful during the installation process.

Along with the shortcomings, mineral wool is not without advantages:

• Reliable thermal insulation;
• Not afraid of moisture;
• High degree of sound insulation.

4.Glass wool

Insulating a bathhouse with glass wool will cost no more than its analogues. And according to certain criteria, it is not inferior to other materials: it holds heat well and is easy to install.

A significant disadvantage of glass wool is its instability to hot air.

5.Foil insulation

To insulate the sauna ceiling, it is recommended to use materials that reflect light. Insulating mirrors have become widespread. Due to a special aluminum coating, they reflect and do not transmit heat through the ceiling. Foil insulation for a bathhouse is recommended to be used in combination with classic materials.

Insulation of the sauna

Having decided on the choice of one or two heat-insulating materials, proceed directly to work. Insulating a bathhouse from the inside with your own hands is a difficult process that requires skills in the construction industry. If you are confident in your abilities, then go for it. Otherwise, it is better to seek the help of specialists from the Marisrub company.

It should be noted that the process of thermal insulation of a wooden or brick sauna is almost the same. Therefore, there is no point in focusing on the insignificant difference.

Before you start insulating the walls, ceiling and floor, it is wise to take care of the vapor barrier. Even if you have chosen moisture-resistant insulation, during operation condensation will gradually begin to penetrate through the internal layers of the insulating material and have destructive effects.

To isolate the insulation from moisture, use aluminum foil. The solidity of the vapor barrier is achieved through metallized tape, which is used to glue the joints of the foil sheets.

We warm the floors

It is correct to start insulating a sauna not from the ceiling or walls, but from the floor. In the bathhouse it can be continuous or leaking. Considering that structures differ from each other, insulation of each type occurs differently.

It is better to use mineral wool. It is laid on a subfloor made of boards and covered with a layer of waterproofing. Final stage- filling the floor.

When installing leaking floors, dig a pit 50 cm deep and fill it with 5 cm of sand. After careful compaction, a 20-centimeter layer of insulation is laid - polystyrene foam, which is poured cement mortar with styrofoam chips.

After drying, the concrete is covered with a layer of waterproofing, not forgetting the walls.

Then they again fill it with cement and vermiculite, spread a reinforcing mesh and cover it with a layer of concrete with fine crushed stone. On at this stage the work makes a slope in the direction where the water will flow.

The work is completed by laying the finished floor on posts.

We insulate the walls

Insulation of bathhouse walls from the inside occurs in stages:

1.Using wooden slats or timber, we apply sheathing to the surface of the walls. The gap between the slats must be made smaller than the width of the heat-insulating material.

This is done so that the insulation fills the resulting spaces and prevents the formation of bridges for cold air. It is recommended to use mineral wool or basalt fiber slabs as insulation.

2. Having laid the heat insulator, cover it with any vapor barrier with foil. In this case, the reflective side of the aluminum surface is located inside the sauna.

The vapor barrier is placed between the slats and fixed to them.

Thermal insulation of the steam room walls is ready! Other sauna rooms are insulated using the same principle. Instead of foil for a vapor barrier, thick kraft paper for wrapping is suitable.

When insulating buildings made of bricks or blocks, it is recommended to increase the thickness of the basalt insulation so as not to lose heat.

We insulate the ceiling

Thermal insulation of the ceiling occurs by analogy with the principle of wall insulation.

According to the laws of physics, the closer to ceiling covering the hotter the air will be. Therefore, fire-resistant insulation is chosen for the ceiling. Mineral wool is perfect.

If there is an attic in the bathhouse, then a vapor barrier layer is made above the insulation - an aluminum film.

Insulation is placed under, above or between the rafters. If you're looking for the easy way out, lay a continuous layer of insulation between the rafters.

Finally, cover the heat-insulating material with a layer of waterproofing. Do not forget about the air gap of 20 mm. This is done taking into account the increase in insulation by a third of the width under the influence of moist air.

If there is no attic in the bathhouse, expanded clay is often used as insulation for the ceiling. A 25 cm layer of thermal insulation is poured onto the vapor barrier layer.

The construction market offers for insulation bath room thermal insulation panels. The main advantage of the material is the possibility of refusing waterproofing, the minus is that they require a reliable vapor barrier layer.

Properly performed interior decoration Baths guarantee not only a pleasant stay in the company of friends, but also safety. So come to your choice building materials and performing work with maximum responsibility.

Insulating a steam room with your own hands: step-by-step instructions (video and photos)

Insulating a steam room with your own hands is quite simple. You just need to read the step-by-step instructions and prepare everything you need for work.

Insulating a steam room from the inside step-by-step instructions

Insulating the steam room allows you to solve the problem of heat loss, otherwise the effect of visiting the bathhouse will be reduced to zero. The thermal insulation of a given room can be called high-quality if insulation work has been carried out on the ceiling, floor and walls.

The temperature in the steam room must be maintained at a high temperature. At the same time, heat loss must be minimized, and insulating the steam room from the inside will help achieve the required level of thermal protection. When constructing a bathhouse building, this room should be equipped according to all the rules.

The better the thermal protection of the steam room, the less fuel will be required to heat it during operation, and the longer the steam will be able to remain in it, which has a beneficial effect on the human body. Regardless of the material used to build the bathhouse, the insulation process certainly consists of thermal insulation of the ceiling, flooring and walls.

Materials used in arranging steam rooms

To insulate the steam room internally, in former times people used exclusively environmentally friendly materials. They not only retained heat well and were easy to use, but at the same time had a number of disadvantages, including susceptibility to rotting.

Modern materials meet many of the requirements for them:

• successfully withstand high temperatures;
• well tolerated high humidity air;
• do not emit substances harmful to human health;
• look aesthetically pleasing.

In order to thermally insulate the steam room from the inside, the following building materials are used:

• wooden slats(for arranging the sheathing);
• mineral wool or glass wool;
• polyethylene film;
• penoizol (can be replaced aluminum foil);
• expanded polystyrene;
• perlite;
• concrete mortar;
• reinforcing mesh.

Before insulating a steam room in a bathhouse from the inside, you should prepare the following tools:

For internal lining Steam rooms are most often chosen using wooden slats, boards or lining, which depends on the personal preferences of the owner of the building. It is wood that meets the operational requirements for such premises.

Ideal wood hardwood with low density are alder, maple, linden and aspen. Concerning coniferous trees, then at high temperatures their wood will begin to release resin.

Insulation of steam room walls from the inside

Properly performed insulation of the walls of a steam room from the inside is a structure of several layers: steam, hydro- and heat insulating. Special attention attention should be paid to the arrangement of the first of them, since it should protect the remaining layers from the influence of hot steam. If it penetrates into the insulation, this material may become wet and lose all its properties.

Most often, a vapor barrier is installed using aluminum foil or special insulators that are coated with a foil layer, for example, it can be penoizol (the material is shown in the photo). At the same time, experts do not recommend using such well-known vapor barriers as roofing felt, polyethylene, glassine when covering a steam room, since at high temperatures they begin to release toxins that are dangerous to human health.

In turn, the foil prevents the insulation from getting wet and at the same time provides the effect of a thermos, as a result of which heat will be retained indoors for a long time.

Waterproofing is essential to protect the thermal insulation material from moisture. The fact is that poorly laid waterproofing material in conditions of high humidity, namely the air in the steam room, can trigger the onset of the rotting process. The appearance of mold and mildew on walls can cause irreparable harm to both the structure and human health.

For waterproofing, foil or special film materials are most often used. The joints of the panels must be sealed with tape to prevent steam and condensation from penetrating into the insulation. All these materials for arranging waterproofing are mounted using construction stapler.

The next layer when creating thermal protection for the steam room will be the installation of thermal insulation, which is made using materials that have the property of retaining heat. These include mineral wool and glass wool.

The first of the above-mentioned insulation materials is an environmentally friendly natural product. But mineral wool is afraid of moisture and loses its properties when wet. When using mineral wool it is necessary for everyone possible ways to prevent the penetration of moist air, so this insulation is carefully wrapped with foil and films.

Glass wool differs from mineral wool in that it does not get wet and therefore can be used to insulate a steam room with inside. When the steam room is insulated from the inside - step-by-step instruction suggests that work should begin by fixing wooden sheathing to the walls, to which insulation is then installed.

Thermal protection of the floor and ceiling from the inside

Basically, heat loss in the steam room occurs due to insufficient thermal insulation of the ceiling, since warm air flows always rise upward. For this reason, the ceiling should be insulated not only from the room side, but also from the attic side.

Thermal insulation of the ceiling on the steam room side is carried out in the same way as it is done with walls. First of all, fix wooden sheathing. Then they attach it to it thermal insulation material, preferably glass wool. It is covered with a vapor barrier on top, and an outer finishing layer is installed on it - most often lining.

As for the ceiling on the attic side, it can additionally be insulated with straw, clay, sawdust or other materials. Near the chimney pipe for protection fire safety special mastics are used.

Currently, various floor coverings are installed in steam rooms. You can insulate the floor, for example, with expanded polystyrene. This material is characterized by high mechanical strength, fairly low thermal conductivity, and in addition, once in a humid environment, it does not change its qualities.

When using it to insulate a steam room from the inside, the step-by-step work looks like this:

1. A waterproofing layer is placed on a prepared, level base using a special film, on which polystyrene foam boards are laid tightly one to the other.
2. To give the structure greater strength in order to increase its service life, a reinforcing mesh is mounted on the polystyrene foam and concrete mortar is poured. When performing work, you must not forget about arranging a slight slope to ensure water drainage.
3. After the concrete has completely hardened, which usually takes about a month, you can begin laying the finishing floor surface. A good option is to lay ceramic tiles.

You can also insulate the steam room floor using a natural material such as perlite, which is sand expanded by a special method. To create insulation, take 2 parts perlite and part water, mix and combine with cement. Mix the whole mass thoroughly.

The base of the steam room floor is poured with a concrete screed, on top of which an insulating mixture is placed and allowed to dry for a week. Then the screed is made again and the work is completed with a finishing floor covering made of finishing material.

Sometimes in a steam room, wooden gratings are placed on a high-quality concreted, durable and reliable floor, which should be periodically dried during operation to avoid rotting and rapid deterioration.

How to insulate a steam room?

• What will be required to carry out the work?
• Stage 1: ceiling insulation
• Stage 2: wall insulation
• Stage 3: floor insulation
• Stage 4: insulation in the steam bath from the outside

Often the problem of thermal insulation of apartments and houses is not paid attention to, but for baths it is of particular importance. After all, if you do not insulate the steam room, then the heat will not stay in it for a long time. That’s why it’s so important to insulate the bathhouse from the inside. paying special attention to the steam room. After all, this is where you have to spend more time.

At the same time, it is necessary to insulate the steam room with high quality, performing all the work in stages. Below are step-by-step instructions. She will help you in this difficult, but so important matter.

What will be required to carry out the work?

The first step is to prepare all the materials and tools that will be needed to insulate the steam room. Here is their list:

• rolled thermal insulation material;
• bars;
• self-tapping screws;
• nails;
• screwdriver;
• saw;
• foil;
• Styrofoam;
• glass wool;
• waterproofing material;
• polyethylene film;
• blank paper;
• masking tape;
• wood material for cladding (linden, aspen);
• anti-corrosion composition;
• building level;
• facade panels;
• water-repellent varnish for wood.

Stage 1: ceiling insulation

Scheme of ceiling insulation in the steam room.

First of all, thermal insulation in the steam room should be done for the ceiling. First you will need to cover it with rolled paper; it is important that its joints overlap (from 10 to 15 cm). After this, it needs to be strengthened, otherwise deformation will occur during further work. To do this, you need to take small blocks (size 5x5 cm) and nail them to a roll of thermal insulation material.

It is important here to create a monolithic coating so that seams with cracks do not form, otherwise the tightness of the waterproofing will be compromised.

As a result, steam will penetrate into the rolled thermal insulation material, which will lead to its deformation and deterioration of its performance characteristics.

Scheme of the ceiling in the steam room.

Now you need to secure the foil with additional blocks. This will prevent it from peeling off, and the finished sheathing will also allow you to quickly lay down the finishing material. Wood should act as it. The use of non-ecological materials here is simply unacceptable. After all, you will inhale the harmful substances that they emit when taking water treatments in the bath. As a result, instead of improving your health, you will, on the contrary, worsen it. It’s great if you use linden or aspen for cladding the ceiling. These materials emit special resins that heal the body and make the atmosphere in the bathhouse better, as a pleasant smell spreads.

You can attach the finishing material to nails, making sure to pre-treat them with an anti-corrosion compound. The wood itself must be coated with a water-repellent varnish. It is better to do this before it is fixed to the ceiling. After all, then you will be able to process it from all sides at once, which will extend its service life.

Using boards you need to create an even surface. To prevent misalignment, be sure to use a building level. In addition, for finishing, choose only those boards that have the same thickness, otherwise differences in height in the finished coating cannot be avoided.

Stage 2: wall insulation

Scheme of wall insulation in a bathhouse.

Do not assume that only the ceiling needs to be insulated. The walls also need additional finishing using insulating materials. Therefore, having completed work with the ceiling, you will need to move on to them. It is also necessary to start insulating walls by laying out rolled material. It must then be nailed down with a wooden frame, which is immediately lined with foil. But here it is necessary to take it with a thickness of 65-70 mm. After all, much more heat escapes through the walls than through the ceiling. Therefore, the use of thinner material here is not permissible. Lay it out overlapping, and cover all joints several times with masking tape. Then it will be possible to make the surface of the walls as airtight as possible. As a result, the steam room will be as warm as possible.

After this, it is installed on the foil fixed on the surface of the walls. wooden frame. And the finishing material is already installed on it. It is not necessary to use boards here. you can choose lining for the walls. By the way, you can also decorate the ceiling with it, but then the insulation in the steam bath will cost a pretty penny, but if you have allocated a significant budget for this, then feel free to opt for this material. Aesthetic and operational properties you won't be disappointed. The wall decoration will turn out great and will delight you every time you take water treatments.

Stage 3: floor insulation

Scheme of floor insulation in a bathhouse.

Now you can insulate the floor in the steam room. Here the work is carried out according to a slightly different scheme. The first thing you need to do is waterproofing. It is necessary to prevent mold, mildew and rot from appearing inside the floor. This layer will protect the floor from condensation. To create it, you will need to use plastic film. It is laid out over the entire surface of the floor. If there are seams, make large joints and seal them with masking tape.

Next you will need to create another layer on top of the film. It must be laid out from clean, thick paper. It is necessary to ensure that no harmful substances are released from the base of the floor. In addition, such a layer will minimize the loss of hot air. It will definitely need to be secured to a wooden frame of small width. And you need to lay out mineral wool slabs on the frame and fix them with self-tapping screws.

Then it is laid out on the floor surface next material: Styrofoam. It needs to be attached on top of the cotton wool using small nails. After which you will need to cover it with foil and put plastic wrap on it again. So many layers need to be created in order to minimize heat leakage through the floor, which occurs through it in large quantities. As a result, the insulation will be of very high quality.

And the last thing you need to do is create another frame on the floor surface. It should be thicker than the previous one. It is necessary for subsequent finishing. After all, you will need to lay boards on the floor surface. Pre-treat them with water-repellent varnish.

Stage 4: insulation in the steam bath from the outside

If your bathhouse is wooden, then you must insulate it from the outside. After all, a sealed floor, walls and ceiling in this case will not be enough. Therefore, here you need to create a crate outside the bathhouse; mineral wool slabs should be laid on it. They need to be fixed with screws or nails. After which it is lined with plastic film. Next, the façade panels are laid on it. All of them must be varnished. This will protect them from adverse factors. environment.

Insulation in a steam bath consists of these stages. As it becomes clear, complex work needs to be carried out here. It is not enough to insulate only the surface of the walls and floor, you also need to not forget about the ceiling and outer skin. This is the only way to do quality work. The result will not disappoint you. And since all the instructions are presented in accessible form and is step-by-step, then using it you can do everything yourself.

The main thing is to prepare everything in advance necessary tools and materials. We wish you good luck in insulating your steam room!

How to insulate a steam room in a bathhouse with your own hands

Preface. In Rus', since ancient times, bathhouses were built from log cabins; today, along with this traditional material, timber, foam block, expanded clay and others are used modern materials. Thermal insulation of the steam room will solve the problem quick loss the heat and heat from the steam room will not leave so quickly.

How to properly insulate a steam room wooden bath? Thermal insulation of the dressing room and steam room will be of high quality if the work touches all three planes of the steam room - floor, walls and ceiling. Most of heat escapes through the ceiling of the bathhouse, but other surfaces should not be ignored, including the door to the bathhouse. Let's look at how to properly insulate a steam room in a bathhouse.

Is it necessary to insulate the steam room in a bathhouse?

Photo. Insulating a steam room from the inside with your own hands

Despite the low thermal conductivity of modern and traditional materials, any steam room needs high-quality insulation. Especially when it comes to internal thermal insulation structures in the steam room - walls, floor and ceiling. Insulating a steam room is a very important task; when working, you should strictly follow the manufacturers’ instructions and take into account other nuances.

For example, not all heat and vapor barrier materials can be used when finishing the floor and ceiling in a bathhouse. Many materials do not withstand moisture, and if used in this room roofing felt or glassine, then a visit to the steam room can be spoiled by unpleasant odors from these materials. The choice of thermal insulation is made depending on the material from which the bathhouse was built.

How to insulate a steam room in a bathhouse from the inside

The most common materials for the construction of bathhouse walls are logs, timber, foam concrete, aerated concrete or expanded clay concrete. Compared with natural wood, the thermal conductivity of the blocks is higher, which means that thermal insulation of the steam room is simply necessary. But, before considering the technology for carrying out the work, you should figure out how and how to insulate a steam room in a timber bathhouse with your own hands.

If basalt wool was chosen as thermal insulation, then high-quality mineral wool vapor barrier should be performed, since this material absorbs moisture. The most balanced solution for finishing wet rooms is penoplex or foil penofol. Extruded polystyrene foam is often used for self-insulation strip foundation and blind areas of a private house.

For owners of bathhouses made of blocks, there is no question of whether or not to thermally insulate the room from the inside. It is important to learn how to insulate a steam room in a block bathhouse yourself. Thermal insulation technology is divided into three main stages: arrangement and insulation of the walls, floor, and ceiling of the steam room of a brick bath. All work can be done on your own and inexpensively.

How to insulate the walls of a steam room with your own hands

Photo. Thermal insulation of walls in a log steam room

Thermal insulation log walls in the steam room, the inside is a layered “pie” of vapor barrier, thermal insulation and waterproofing layers. Vapor barrier film from the side warm room protects mineral wool from moisture and steam, in addition, it additionally creates the effect of a “thermos” in the steam room and is a natural heat reflector.

Roll waterproofing prevents moisture from entering walls made of logs or timber, protects the structure from condensation and the formation of fungus, and prevents the process of rotting of the structure. To do this, use polyethylene film, foamed polyethylene or foil. The waterproofing film is laid between the thermal insulation layer and the walls in the steam room made of blocks or wood.

The insulation layer itself is placed between guides fixed to the wall. When installing the frame, please note that the distance between the guides should be 1 cm less than the width of the mineral wool slab so that the basalt slab fits tightly into the frame. If you use slab insulation, then all cracks should be thoroughly foamed.

How to insulate a steam room ceiling with your own hands

Photo. Thermal insulation of the ceiling in the steam room

If many people neglect the thermal insulation of walls, then insulating the ceiling in a steam room with your own hands is simply necessary in any bathhouse. Since this part of any building is the most vulnerable in terms of heat loss. Through the ceiling of the steam room, hot air leaves the room in a short time.

To insulate the ceiling in the steam room, inexpensive base materials were previously used - sawdust mixed with ordinary earth or expanded clay. The ceiling boards above the steam room were covered with loose thermal insulation, thereby significantly reducing heat loss in the room. These “old-fashioned” methods, even with the advent of new materials, have not lost their relevance to this day.

The ideal option for finishing the ceiling in a steam room is thermal insulation of this structure from the outside, i.e. from the attic side. To do this, use glass wool or basalt insulation. Where the chimney pipe comes out of the ceiling, you should use non-flammable insulation - expanded clay or Rocklight mineral wool. Consider further how to insulate the floor in the steam room.

How to insulate the floor of the steam room with your own hands

Let's consider a more common option for thermal insulation of the floor in a steam room - using polystyrene foam or extruded polystyrene foam. Foam extrusion meets all necessary requirements for thermal insulation of wet rooms. This material does not absorb moisture and is not afraid of rodents, but the insulation should only be laid on a flat base.

Most often, the floor in the bath is insulated under the screed. To do this, a waterproofing film is laid on the ground to protect against groundwater, then fits slab insulation. Gaps and cracks between slabs should be sealed polyurethane foam. At the end, a reinforcing mesh is laid and concrete screed. To waterproof concrete, penetrating composition Penetron or liquid glass should be used.

Used to finish the floor in the steam room floor tiles or porcelain stoneware. You can also lay a wooden floor on joists, which will be more pleasant and warm for your feet.

How to insulate a steam room

Without a good steam room, a bathhouse loses its meaning of existence. During the construction of baths, special attention is paid to this room. The main task of the steam room is to store hot air and steam for a long time, to ensure the quality of bath procedures at the highest level. And the main job of the builders is to insulate the steam room in the bathhouse in such a way as to eliminate prolonged heating and rapid cooling, and to increase the concentration of steam.

Poorly performed thermal insulation work and the use of low-quality materials will inevitably lead to the appearance of dampness, mold, and rotting wooden structures. This applies to all surfaces of the steam room: floor, walls, ceiling. It is very important to carefully and step-by-step carry out work on insulating the steam room from the inside; step-by-step instructions will help you correctly navigate the sequence of actions and the choice of materials.

Choice of insulation

A steam room is a specific room, so the choice of thermal insulation materials for walls, ceiling and floor should be approached responsibly. The insulation for the steam room must be moisture resistant, not afraid of significant temperatures, and not emit toxic substances. Mineral wool, or more precisely its variety - stone or basalt wool, most closely fits these definitions. It is produced in the form of plates of various thicknesses and dimensions. The material is easily cut with a regular construction knife, so stone wool slabs are very easy to fit required sizes. To furnish the floor and ceiling on the outside, loose insulation materials are used - expanded clay or expanded perlite.

Foil material is most suitable for steam and waterproofing for steam rooms. It is available in foam or kraft paper. You can use any of them, but in the case of insulating a steam room from the inside, preference is usually given to the second option.

The procedure for performing insulation procedures

The process of warming the steam room in the bath goes from top to bottom. That is, work starts from the ceiling, then the walls and, lastly, the floor. It would not be superfluous to remind you that before starting insulation work you should clean wooden surfaces from dust, signs of fungal manifestations. It is necessary to treat the wood with antiseptic preparations and a fire retardant, since it is possible to insulate a steam room in a bathhouse from the inside efficiently and effectively only with a well-prepared base.

Ceiling insulation

Thermal insulation of the ceiling is most conveniently performed from the side of the attic. Ideally, do this on both sides, because the ceiling is one of the most vulnerable parts of any building, especially a bathhouse. It is through this structure that the largest share of heat loss from the inside occurs. So, from above:

• a layer of rolled vapor barrier is attached to the rough ceiling, tightly closing all joints and making an overlap on the pediment and rafter elements;
• pour a layer of expanded clay or foamed perlite, level it;
• in places where the thermal insulation comes into contact with the chimney, they are treated with fire-retardant mastics.

Insulation of a steam room in a wooden bath from the inside on the ceiling occurs as follows. If the ceiling structure below has smooth surface, then a frame is built on it. If there are ribs, there is no such need. The first layer of the thermal insulation cake is a vapor barrier membrane, which is attached to the base, observing the configuration of the ribbed surface. Then stone wool slabs are laid as tightly as possible between the beams and covered with another layer of vapor barrier. The next stage of insulating the steam room, its upper part, is the installation of a protective layer of foil material. The joints between individual sheets are sealed with aluminum foil tape. Particular attention must be paid to the junctions between the ceiling and the walls in order to prevent the slightest possibility of the appearance of “cold bridges”. If necessary, use polyurethane foam.

Baths are built not only from wood; there are options for brick buildings. In such buildings the process of execution thermal insulation works looks a little different. Insulation of a steam room in a brick bathhouse begins at the stage of constructing the roof structure. Supporting ceiling beams, which are subject to embedding in brick walls, before laying, wrap two to three layers of glassine or roofing felt. The nests for them are made slightly wider than the beams themselves, and the free space is filled with polyurethane foam or mortar. From the outside, the recesses are covered with masonry. Next, the ceiling structure is installed, and insulation is performed in the same way as in a log house.

Wall insulation

Insulation of the wall surfaces of a brick bath begins with the application of a waterproofing layer to them. Most often used rolled materials or mastics that do not contain bitumen. Because the specific smell of this material, when heated, can penetrate the room and spoil the positive impression of visiting the steam room. Further, the process of producing thermal insulation work for walls made of brick and wood is the same and is performed in the following order:

• Vertical bars are placed on the walls in increments equal to the width of the stone wool slabs;
• using a construction stapler, attach a vapor barrier membrane, carefully wrapping it around each beam;
• between the bars, heat-insulating material is tightly laid in one or two layers, depending on the thickness of the slabs; stone wool is a little springy, so it holds well on its own and does not require additional fastening;
• The top vapor barrier layer is made of aluminum foil on kraft paper; you can use foil material on a foam base, but the first option works more reliably in humid conditions.

The foil is secured end-to-end, and the seams are covered with a special adhesive-based protective tape. All work must be carried out carefully and responsibly, but special care is required when sealing corners and places where walls meet the ceiling surface.

Floor insulation

Making warm floors in the steam room is no less important than properly insulating the walls and ceiling. You can use two options: using slab materials or bulk. However, in both cases, you need to start with leveling the surface and a rough preparation device. And here, too, there can be two versions: with and without drain. By and large, water is not used in the steam room, so there is no need to install a drain hole there. But some developers do this. Then, when arranging the floor pie, starting from the preparatory layer, slopes are made towards the drain. Otherwise, the floor must be strictly horizontal. Now about the floor structure itself:

1. Insulation with polystyrene foam boards. After rough preparation, a layer of waterproofing is laid with a slight overlap on the walls. Then the insulation boards are laid in one or two rows, depending on the thickness. The next step is laying the reinforcing mesh and then screeding it with cement-sand mortar.
2. For insulation with bulk materials, expanded clay or perlite is used. First, waterproofing must be done. Then pour a layer of dry insulation required thickness, level it using the plaster rule according to the level. The covering layer is made concrete mixture or solution.

The clean floor in the sauna is made of rough ceramic tiles and porcelain stoneware. Traditional ones are often used wood coverings. Well behaved terrace board. In addition, its use is useful in terms of safety, since the board has a corrugated surface and does not slip.

Wall and ceiling cladding in the steam room

Wooden lining is usually used to cover the walls and ceiling in the steam room. Each owner chooses and arranges the design of the steam room of the bathhouse according to his own taste. However, there are general rules that must be followed. First of all, this is the type of wood from which the lining is made. Linden, aspen, and larch are considered the most suitable. It is undesirable to use breeds containing a large number of resin At high temperatures they emit fumes with a heavy odor. The next requirement is that the lining must not have knots, cracks or other defects. That is, high-quality material is best suited for lining a steam room.

The principle of covering walls and ceilings is traditional. A sheathing is made using aluminum foil with the beams positioned for the planned layout of the lining. Then the planks are attached to the frame, connecting them with tongue-and-groove locks.

Insulating a steam room from the inside - step-by-step instructions

Before insulating the steam room, the owner of the bathhouse must select the correct thermal insulation material, focusing on the following recommendations:

First, the insulator must demonstrate high stopping power. The heat transfer coefficient should not rise above 0.2 W/(m K). And this is only for flooring. And for insulating walls and ceilings, it is better to use a material with a coefficient of 0.2 W/(m K).

Secondly, the insulator should not react to moisture. Especially the flooring material. For walls and ceilings, we can use a membrane or reflector that cuts off moisture, but in the case of the floor, this material will not work.

Thirdly, the open (floor) insulator must have high mechanical strength. Along the walls and attic floor There are no special requirements. Here the characteristics of the material can be improved through external finishing.

Fourthly, insulating a steam room requires constant contact of the material with an area of ​​high temperatures. Some amateurs manage to heat the room up to 100-120 degrees Celsius, and 75-80 °C is considered a normal temperature. Therefore, the insulation should not melt or catch fire even after a long, many-hour stay in this temperature range.

Fifthly, the material must be absolutely neutral to the human body. Selection harmful substances and provoking allergic reactions is excluded in principle. People go to the bathhouse for health, not for new illnesses.

As a result, granulated expanded clay should be considered the optimal insulation option for the field. It is not afraid of mechanical stress or moisture. It is better to use regular or foil-clad mineral (basalt) wool on the walls and ceiling. It will withstand heat, and a layer of finishing will protect it from moisture and possible mechanical stress.

Polystyrene foam, expanded polystyrene, foil polyethylene are not suitable for insulating a steam room - they cannot withstand heating even up to 70 degrees Celsius.

Well, now that we have selected the materials, you can begin to directly insulate the steam room from the inside, having first studied the step-by-step instructions for the floor, ceiling and walls.

How to insulate a floor - layer by layer review

To do this, we will have to form a multilayer structure in the direction from the ground, consisting of waterproofing, thermal insulation and finishing. The first layer is waterproofing. It is made in the form of a plastic film, which is laid on the prepared soil. Moreover, the preparation consists of adding a layer of sand, at least 15 centimeters thick.

The second layer is thermal insulation. It is formed on the basis of expanded clay bedding. The thickness of this layer is usually equal to double the thickness of the walls and ranges from 30 to 40 centimeters. Moreover, upon completion of the formation of the bedding layer, we must reach the level of the first crown of the bathhouse frame.

Expanded clay is perfect for thermal insulation of the steam room floor

Next, a reinforcing mesh with 20-centimeter cells is laid on the expanded clay and the screed is poured using sand-cement mortar with filler. Optimal thickness screeds - from 5 to 8 centimeters. At the same time, along the perimeter of the floor, at the level of the future baseboard, it is necessary to fill a waterproofing skirt made of foil, which protects the logs from contact with concrete.

For finishing heat-resistant floor is used tile or boards laid on the sheathing.

Insulating the ceiling - step-by-step instructions

To insulate the ceiling in the steam room, you need a completely different heat insulator - foil-clad mineral wool. It can withstand heating up to 700 degrees Celsius and can easily withstand the usual temperature in this steam room zone, which does not rise above 160-180 °C.

The finishing process itself begins with covering the ceiling with an antiseptic primer, which protects the boards from fungus and mold. The second step is to lay sheathing boards on the ceiling, the depth of which should be equal to the thickness of the insulation (usually 10 centimeters). The step of laying the boards is equal to the width of a standard strip of mineral wool.

The ceiling is insulated with foil mineral wool

The third step is laying the insulation. After completing the assembly of the sheathing, the space between the boards is filled with mineral wool, laid with foil outward (towards the floor). And all joints are carefully glued with foil tape. After completion of the work, there should be no gaps left on the ceiling.

The final step is installation on top of the sheathing finishing board(lining) or plywood panels. Moreover, in this case, it is necessary to read the description of the specification for the lining - options made of pine and spruce and other resinous trees are not suitable in this case. The ideal lining for a bathhouse is made from hard deciduous trees.

How to insulate walls in a steam room - an overview of the process

Installing vertical thermal insulation on the walls of a bathhouse does not require the use of expensive foil-coated mineral wool. In this case, it is enough to take ordinary mineral wool and aluminum foil, which will serve as a good vapor barrier and shield from high temperatures.

The installation process itself is as follows:

• We saturate the walls with an antiseptic - it will protect the log house from rot and fungus.
• We fill the walls with boards 3-4 centimeters thick and 2-3 cm wider than the depth of the insulation. The spacing of the boards should match the width of the mineral wool roll. At the end, all boards must be soaked with an antiseptic.
• We lay mineral wool on dry logs (the antiseptic must dry), filling the spaces between the boards.
• We stuff aluminum foil over the sheathing, rolling it out in horizontal stripes from bottom to top. In this case, the upper strip should overlap the lower one (2-3 centimeters will be enough). It’s better to use staples (from a stapler) as fasteners. Moreover, it is better to seal the joints with foil tape.
• We stuff 2 centimeter thick planks onto the boards, pre-impregnated with an antiseptic. This will create a counter-lattice. And at the end, on top of these planks, we install hardwood paneling.

Such a scheme allows you to collect very effective thermal insulation, protected from mechanical influences by clapboard finishing. Therefore, almost all steam rooms are finished according to this scheme.

Insulating a steam room from the inside step-by-step video instructions

Insulating a steam room from the inside step-by-step video instructions Insulating a steam room allows you to solve the problem of heat loss, otherwise the effect of visiting the bathhouse will be reduced to zero. Thermal insulation

Insulating a steam room from the inside yourself

The bathhouse helps us relax not only with our bodies, but also with our souls.

Therefore it is important that Decoration Materials not only fulfilled their direct function, but also pleased with their attractive appearance.

A few general rules

The first step before the next treatment is preparing the work surfaces.

It is necessary to inspect the base to see if there is any fungus and mold on it.

There should also be no foreign inclusions or protrusions.

To get rid of fungus, it is enough to use a regular antiseptic composition.

Without it, insulating the steam room from the inside will remain ineffective.

It is important to pay attention to the safety of materials.

The main requirement in this case is the ability to withstand high temperatures. Materials must not absorb moisture and must have reliable protection from mold.

And stay durable. Aluminum foil and basalt are good, modern solutions. The technology itself plays no less a role than the materials.

How can I insulate

During the work we will get a kind of “sandwich”. It usually consists of several layers.

• Waterproofing. Prevents the appearance of fungal and mold formations. And prevents the activation of decay processes. This layer also protects the walls from the appearance of condensation on them. It forms when a surface is exposed to hot steam. Polyethylene film or foil are considered best waterproofing materials. This is also required for insulating a steam room from the inside in a wooden bathhouse.
• Thermal insulation. Plain, clean paper is first laid on the base. The insulating layer comes only after this. paper base makes it so that it is not even released into the air minimal amount harmful substances. The paper ensures that the minimum amount of hot air escapes. After this, a wooden frame with the same width as the one itself is attached to the top. insulation material. Synthetic board or mineral wool often make excellent insulation materials.
• To protect thermal insulation from the effects of steam, a vapor barrier is needed. It also reflects thermal radiation. And it creates a kind of “thermos” effect. This layer is made of foil, with a thickness of up to 65 microns. Installation is carried out to a wooden sheathing. What are small nails or a stapler used for? The main thing is to carefully cover all edges and joints with foil. Then the steam will definitely not penetrate inside the insulation.
• Internal lining. For which all surfaces are covered with clapboard. The frame is mounted on top of the heat-insulating layer. The lining itself, which is made from different breeds tree. The most important characteristic in this case is the minimum density.

What materials to choose

The question is not only about choosing between materials of artificial and natural origin. There are several other factors to consider.

This applies to appointments and appearance, cost. Materials that solve this issue can be classified into one of the following groups depending on their properties.

• Wall blocks and slabs.
• Matte and lamellar, fibrous varieties.
• Backfills with different densities

Several groups are also distinguished according to their chemical composition:

• Which have a plastic base. This includes polystyrene foam and polystyrene foam.
• Technoblocks and technovets. This is a group of technical insulation materials.
• Inorganic compounds include glass and mineral wool, basalt fiber.
• Organic. These include wood concrete and fibrolite, aqua wool.

Each variety has both advantages and disadvantages. For example, for insulating steam rooms from the inside, plastic insulation materials are not very suitable.

This is due to the fact that such a base does not resist open fire. But they can be used to insulate other rooms included in the bathhouse.

In turn, organic bases benefit from environmental safety. Their cost always remains affordable. But, if you do not use special processing compounds, the material remains flammable.

Inorganic varieties are considered more versatile and practical. This is why mineral wool has become such a popular solution.

Internal insulation will be more effective with materials such as:

• Aluminum foil
• Polyethylene materials
• Glassine base
• Ruberoid types

Vapor barrier with glassine and roofing felt will not give the desired result. After all, these materials, when exposed to high temperatures, emit chemically active and harmful substances.

But glassine is generally used to insulate baths. But best of all, it has proven itself in conjunction with materials such as lining, aluminum foil, mineral wool and log house.

There are several schemes by which insulation is carried out. But one of them has become the most widespread. For example, when using lining with fiber insulation.

• It all starts with creating a frame on the working wall surface. We take timber battens, horizontal and vertical, and fix them on the wall. The timber should be thicker than the insulation, but only by 20-30 millimeters. This reserve is necessary to predict possible shifts.
• After this, the wall is sheathed using mineral wool.
• A layer of vapor barrier is laid on the insulation. The main thing is to overlap the materials. For places with joints and their sealing, thin slats are used. A distance of approximately 3 centimeters should remain between the mineral wool and the vapor barrier.
• The lining is pressed onto the surface of the vertical sheathing. The width of the latter is 40-50 mm. There is still a distance remaining, which will be a kind of gap for the ventilation system.

Such work has proven its effectiveness. But they require certain costs, both in time and in effort.

There are currently materials on the market that greatly simplify the whole process. Moreover, they combine the functions of waterproofing and vapor barrier.

One such option is foil foam. This is a fire-resistant insulation; there are no problems with its installation. As you can see, insulating a steam room from the inside is not a very complicated technology.

The scheme described above is well suited for installing timber buildings. Panel and frame structures have their own requirements for this process. There are several lightweight materials that will become indispensable assistants when working with panel walls:

Treatment of the heat insulator with lime milk acts as an additional requirement. In the future, you will need to dry the base properly. Due to this, fire resistance increases, rotting will no longer threaten the material.

If the walls are used in difficult conditions from a climate point of view, then the walls can be covered with fiberboard, or their equivalent - reed slabs. In warm regions, the use of gypsum, cement and particle board compounds will be relevant.

Work order for ceilings

Ceilings suffer the most from exposure to temperatures that are often 160 degrees. The insulation process itself and its features depend on the design of the ceiling itself.

The work will look like this if there is an attic or ceiling.

• We coat the ceiling boards with clay. Its layer should have a thickness of about 20 mm.
• Clay is needed to effectively retain moisture.
• Wooden chips are poured into the cracks that form between the boards.
• Other materials can also be used for thermal insulation. The main thing is that their thickness is at least 200 mm.

The insulation scheme for rooms where there is no attic looks somewhat different. First, a vapor barrier material is laid there. Sheathing and insulation layer come next, followed by ceiling boards and beams.

Depending on the materials used and design features, the order of work will always vary.

Places where insulation and pipes are connected to each other. Between them it is necessary to make an indent of approximately 200 millimeters so as not to violate fire safety requirements. To do this from rafter legs a special box is constructed.

It will be the part that separates one part of the structure from another.

The main thing when insulating a bathhouse is to ensure that there are no places through which warm air could leave the room. It is also necessary to do everything possible to prevent the formation of condensation.

About floor insulation

You can use two solutions to insulate the floor in a steam room.

Polystyrene has important advantage in the form of a cellular structure. Thanks to this, moisture will never penetrate inside the material. Thermal insulation properties are retained high level, even if the surface experiences severe mechanical stress.

Insulating the steam room from the inside

But this material is most often used in baths that are built of brick.

It requires additional protection, because the brick itself easily conducts moisture inside.

Expanded polystyrene is a material that meets all safety requirements.

But the surface requires preliminary preparation before using such a material.

The main requirements are strength and evenness. You can't do without thorough drying.

A layer of waterproofing is laid on top of the material prepared in advance. Then, on top, the polystyrene foam boards themselves are installed.

Here it is important to ensure that there are no places left without treatment. Gaps and cracks can cause the formation of so-called cold bridges, so they should also be absent.

Decorative coatings are also laid on top, but only after the base has completely dried. Ceramic tile- one of best solutions to date.

But it is also possible to create a collapsible wooden floor. It fits perfectly into the interior of the bathhouse. And walking on such a surface is very pleasant. With a removable structure, you can dry the boards without any problems, which extends the overall service life.

About ventilation in the bathhouse

It is impossible not to consider this issue when touching on the topic of insulation.

Particularly stringent requirements are imposed on this part of the system in the bathhouse. Ventilation should not just provide air flow into the room. It is important that it does not let the cold in, but retains heat.

To solve this problem, it is necessary to create special supply and exhaust channels. An inlet opening is located near the stove, slightly above floor level.

Concerning exhaust duct, then it should be on the opposite side, in the upper part of the room. Special valves provide air flow regulation. One more condition must be met for the system to work properly - that the supply opening be half the size of the exhaust opening.

The operation is regulated by valves. If you manage them correctly, you can achieve the desired results. If you open only one valve, only pleasant aromas will remain in the room, the air will be fresh. Intensive forced ventilation is organized by opening two valves at once.

About floor waterproofing

The base and its materials determine which method of insulation is used in a particular case. Each method should be considered separately.

Concrete floor insulation

This is the simplest and most affordable waterproofing solution for those with a steam room. It is suitable for washrooms where the floor is completely filled with concrete. The order of work will be as follows.

• First, the floor surface is leveled until there are no deviations at all. Even the slightest dimples and tubercles are unacceptable.
• After this they proceed to applying bitumen mastic. You have to wait until it dries.
• Polyethylene film and roofing felt are laid on top of this layer.
• The base of the floor is ready, you can proceed to laying ceramic tiles.

There is a second method. Its implementation is more complicated. But the result justifies all the costs; such waterproofing will pleasantly surprise you with its high quality. There are several steps you need to take.

• A plywood sheet is fixed to the surface of the subfloor.
• Hydrosol is laid on top of plywood. This is a material whose edges extend behind the wall.
• All joints in the waterproofing layer are reinforced with aluminum tape.
• Places of seams and joints that remain untreated are sealed with a regular construction hairdryer.
• Next comes laying the reinforced mesh and laying the concrete mortar.
• The last stage includes decorative cladding.

To prevent all walls from getting dirty, the lining is covered with tape. You also need to look at the age of the log house for the bathhouse. Buildings usually last for at least two years before complete shrinkage. Otherwise, the floor surface will be deformed.

Insulating a wooden floor

This insulation method is very similar to what we wrote about earlier. It features the simplest step-by-step instructions.

• A layer of mineral wool mat with a minimum thickness of 15 cm is fixed under the joists.
• Roofing felt or euroroofing felt is fixed on top of the first layer.
• Wooden structures require mandatory antiseptic treatment. This will eliminate the risk of rotting. And it will protect materials from spontaneous combustion and eating by insects.
• The subfloor must be laid on top of the antiseptic layer. After that, everything is sheathed using clapboard.
• Only the decorative cladding will remain.

Door insulation with mineral wool

Insulating a bathhouse is a process that takes place somewhat differently than in other rooms.

The main difference is the high temperature and humidity, which remain constant here.

But solving the problem is not difficult if you follow simple rules.

Seals must be laid on the wall as tightly as possible.

This will avoid the appearance of cracks and cracks through which hot or cold air.

There will be less chance that excessive moisture and condensation will appear in the bathhouse.

Drying of the insulation is ensured only by ventilation gaps, so it is not recommended to forget about them.

Ceilings must withstand the highest temperatures, this is always worth remembering. The main thing is not to use materials that are too easily deformed for insulation in this part of the room.

Or those varieties that emit harmful chemical substances when they are exposed to high temperatures. Condensation collects on plastic without any problems.

Doors and thresholds in a room also affect thermal insulation performance. A large gap under the door can lead to a low heat capacity of the steam room. There is always a solution - it is enough to install low doors that have a large threshold.

• Insulating a steam room from the inside yourself

  
  The bathhouse helps us relax not only with our bodies, but also with our souls. Therefore, it is important that finishing materials not only fulfill their direct function, but also

All the benefits of a bathhouse may be unattainable if, at the stage of its finishing, the issue of internal insulation has not been worked out thoroughly enough. Even with proper construction according to a time-tested design, the walls of a bathhouse without additional thermal insulation will not be able to adequately retain heat. This means a decrease in comfort during bathing procedures and an increase in the cost of kindling. Meanwhile, there are many options how to ensure that unacceptable heat losses are avoided.

What is the best way to insulate a bathhouse from the inside?

What materials should be used for internal insulation of a bathhouse? For the longest time in the practice of building baths they have been using natural materials, which were available throughout the history of the existence of such structures. Our ancestors often insulated internal surfaces bath walls with available materials: hemp hemp, flax tow, moss, etc. All of the above are still used today, because... natural materials have a very significant advantage over other thermal insulation: they are absolutely environmentally friendly.

However, natural insulation materials have some features that significantly reduce their attractiveness. Firstly, the process of finishing a bathhouse with natural thermal insulation is a very, very labor-intensive process. Even with all the simplicity of the technology, caulking a bathhouse with moss or tow will take an excessive amount of time.

Secondly, natural materials are attractive not only to the owner of the bathhouse. Birds and small rodents love to take them away for their own needs, and insects can easily live in the moss layer, which also do not contribute to the durability of the material. Therefore, the insulation of a bathhouse made from natural materials requires regular updating.

More modern synthetic materials completely devoid of these disadvantages. While no less environmentally friendly, they have a much longer service life, and in terms of thermal insulation parameters they even surpass natural alternatives.

In addition, synthetic materials are not at all afraid of exposure to moisture and the high temperatures characteristic of a bath, they are lightweight and have a simple technology for working with them.

Among the synthetic thermal insulation materials suitable for interior decoration of baths, most widespread expanded polystyrene, basalt fiber, mineral wool and glass wool. When deciding how and what is the best way to insulate a bathhouse inside, you need to understand that, despite the same purpose, each of these materials also has some differences.

1. Expanded polystyrene. Its main feature is good combination excellent thermal insulation, low cost and low weight. However, in relation to a bathhouse, this material can only be used to insulate the external walls of the dressing room. In the washing room, due to high temperatures, polystyrene foam can lose its shape, thereby compromising the thermal insulation. It is generally unacceptable to use this material to insulate a steam room, since it is a fire hazard.
2. Insulation made from basalt fibers cannot boast of a pleasant price tag, but in relation to a bathhouse they can become ideal solution. Since basalt fiber is made from molten rocks, it has some important features:

• absolute non-flammability;
• resistance to mechanical deformation and moisture;
• excellent level of sound absorption;
• excellent thermal insulation.

Basalt insulation is quite convenient for finishing, since it can be easily cut into pieces of the required shape. Their service life, which can reach several decades, is also noteworthy.

Mineral wool. The technology of its manufacture is in many ways similar to the production of basalt insulation. However, instead of rock in the production of mineral wool, much cheaper waste from the metallurgical industry is used. And this most positively affects the cost of such thermal insulation.

Other advantages of mineral wool include the following:

• low thermal conductivity (guarantee of reliable thermal insulation);
• hydrophobicity, allowing the use of mineral wool in conditions of high humidity;
• ability to absorb sound.

Meanwhile, mineral wool, due to the characteristics of the raw materials for its manufacture, does not differ in mechanical strength. Therefore, when working with such material, it is desirable to exercise some caution.

Video about how to properly insulate a bathhouse from the inside.

Glass wool. At its core, this heat-insulating material is an interweaving of thin fibers of inorganic glass. Therefore, glass wool contains a significant amount of air in its volume, which ensures the ability to perfectly retain heat with good vapor permeability.

One of the significant advantages of glass wool over analogues is the relatively low cost. In this case, it is always possible to choose a heater of the required thickness. Both rolls of glass wool of different widths, as well as industrially cut mats and slabs are on sale.

And in this photo is one of the schemes for insulating a bathhouse from the inside.

Insulation of a bathhouse from the inside

A feature of the insulation of internal walls in the bath is a high level of humidity. Therefore, even in the case when thermal insulation insensitive to moisture is chosen, insulation will be required. cover securely with a layer of vapor barrier. If this is not done, then moisture will begin to condense inside the insulation material, which is fraught with a decrease in the ability to retain heat and the likelihood of rotting of the wall material.

As a vapor barrier for baths, aluminum foil can be used, which not only protects the insulation from condensation, but also reflects heat to a large extent. To ensure the integrity of the vapor barrier, all seams between sheets of foil should be glued with metallized tape.

Since the conditions in the bath in different rooms are significantly different, the insulation technology will vary significantly.

1. Insulation of walls in the steam room.

Here the sequence of actions will be as follows:

• dry lathing is hung on the surface of the walls wooden beam or slats;
• the cells formed by the lathing slats are covered with fiberglass cloth;
• heat-insulating material is laid (basalt is best);
• A layer of vapor barrier is laid on top of everything.

The final stage of wall insulation in the steam room will be installation decorative finishing. As such, it is best to use wooden lining.

Another video about insulating a bathhouse from the inside and how to line a steam room inside.

Ceiling insulation.

This operation is in many ways similar to improving the thermal insulation of walls. The differences will be that when insulating the ceiling in washing room and in the dressing room you can refuse to use aluminum foil as a vapor barrier. Instead, it is quite possible to use cheaper polyethylene or kraft paper.

In addition, it is worth leaving a gap of 1-2 cm between the vapor barrier layer and the decorative ceiling cladding. This distance will improve the ventilation of the cladding material to speed up its drying. This moment is quite important, since during bathing procedures the ceiling lining is exposed to the destructive effects of moisture at very high temperatures. The presence of a gap will allow the wood not to rot, but to dry out without deteriorating its performance and aesthetic qualities.

Floor insulation.

Heat loss in the bath can occur not only through the walls or ceiling, but also through the floor, which is especially important in winter. Therefore, floors must also be carefully insulated. The sequence of actions for floor insulation will be as follows:

• a concrete screed is poured on a leveled and compacted base of the earthen floor;
• after the screed has hardened, a waterproofing layer of dense polyethylene or roofing felt is lined;
• sheets or fabrics of insulation are laid;
• another layer of waterproofing is lined;
• another layer of concrete screed is poured.

Since the floors in the bath are constantly in contact with water, when they are insulated, the thoroughness of laying the waterproofing should be given the greatest possible attention.

It is very important that water, even with minor damage to the top layer of the concrete screed, cannot penetrate into the insulation layer and thereby deprive it of its heat-insulating qualities.

Having solved the problem of how to properly insulate the bath from the inside, you can get a guarantee that it will be possible to quickly warm up all the rooms even in severe frosts. The sauna event itself will become much more comfortable, as the temperature will be consistently high.

This is especially important for lovers of a strong steam bath, because with insufficient thermal insulation of the steam room, the procedure will lose its attractiveness. Using the same modern insulating materials, you can permanently get rid of such problems.

External or internal insulation of the bathhouse is mandatory. This reduces fuel consumption and slows down the process of cooling the air in the premises. If the structure is not insulated, then it will take several times longer to heat the steam room to the desired temperature.

We insulate the bathhouse with our own hands

Before the construction of the building, it is necessary to calculate the means and forces for thermal insulation. It is best if the insulation process begins during construction, more precisely, from laying the foundation.

Basic requirements for materials for bath insulation

Cheap solutions (impregnations, septic tanks) will not fulfill the role of good thermal insulation. Of course, protection from moisture is necessary in any case, but this is a separate task. It is necessary to warm the bath rooms separately, using materials specially created for this. Most attention is usually paid to the inside of the washroom and steam room. The selection of insulation and thermal insulation is done with the expectation of a draft building material.

One of the most important requirements for insulation materials is non-toxicity. Because in the bath, under the influence of temperatures, toxic materials can easily cause poisoning. Non-hygroscopicity is also important, the insulation should in no case absorb moisture.

http://kakpravilnosdelat.ru/kak-uteplit-banyu/

When choosing a specific material, you need to rely on the following characteristics:

• resistance to steam and high temperatures;
• good fire-fighting properties;
• environmental friendliness;
• low hygroscopicity;
• ability to maintain shape for a long period.

Types of insulation for baths

All heaters presented on the construction markets are divided into three conditional groups:

Of course, even 50-60 years ago, only natural materials were used, which were brought from nearby forests. This is foam, tow or moss. Today these are already partly elite types of insulation; they cost serious money due to the need to collect them manually. Many fans of natural materials insulate their buildings with rolled jute felt or tow. This material can be purchased at construction stores. When it comes to moss, there are conflicting opinions regarding its use. They say that moss is not an ideal material for insulation because it encourages the growth of mold or fungi. However, the moss itself does not have such properties; most likely, the fungus is formed due to improper cutting of a wooden structure or poor ventilation.

How to work with different types of buildings

The installation procedure and the required amount of work depend on the material from which the bathhouse is built.

Insulation of log houses

When working with timber or logs, you need to take into account the drying time, which can be 10 cm or more. Plus, gaps form between the crowns of such buildings, and cold air blows in just in them. It is best to insulate a log house made of round timber or an assembly of timber with jute fiber.

This material does not rot and has excellent thermal conductivity. Jute itself is a very fragile material, so manufacturers are trying to add flax fibers to it. But if there is already loose material available, you can perform classic caulking. This way there will be less work, and the building will probably retain more heat.

If it is decided to create a bath from wood, then the insulation is laid during construction. It is better to isolate all problematic parts of the log house in the process.

The work is performed in the following sequence:

Insulation of buildings made of brick or foam blocks

If log houses are insulated using a primitive method, then you will have to work hard with the masonry. And there are more financial investments specifically for working with insulation. Additional thermal insulation is necessary, otherwise a well-heated room will cool down in hours. It is better to work, investing in materials, than to stock up on fuel all the time.

A common and proven method is a hinged ventilated facade. The work process does not take place from the inside, but from the outside of the bathhouse. It is necessary to fix the layers of insulation to the walls, and sheathe them with siding or clapboard on top. In the gap between the layers, an air-filled space is formed, thanks to which condensation will not form on the walls and rotting and dampness will not follow.

The width of the frame for a ventilated facade is made greater than the thickness of the insulation, so an air gap is formed inside, which prevents the formation of condensate

For brick building often practice the following trick: indoors they make a steam room out of wood. Brick absorbs heat for a very long time, so it is easier to warm a small steam room naturally if you use a small frame.

A 10x10 beam and sheathing are enough. The process of insulating such an improvised steam room inside a large bathhouse is simple:

You can make it even simpler: do not use timber, but instead immediately attach the insulation to the frame. In this case, an additional layer of waterproofing will be required.

Calculation and selection of materials and tools

We insulate all surfaces of the steam room, wash room and dressing room. And for this you will need:

1. Roll paper (for ceiling and walls).
2. Beam-rail (5x5, for installing insulation on the ceiling and walls).
3. Foil.
4. Insulating tape.
5. Self-tapping screws.
6. Aluminum adhesive tape.
7. Insulation calculated based on the area of ​​walls, ceilings and floors.

Tools you will need:

• screwdriver;
• level and plumb.

Do-it-yourself insulation of a bathhouse

Any stages of insulation are always carried out according to the golden rule - start from the ceiling and end with the floors.

Ceiling insulation

Before you start working with the ceiling, you need to understand that in the steam room you need 2 times more material. After all, we are not working on a sauna, but on a Russian bathhouse, where the steam should linger as long as possible.

The technology is like this:

1. We cover the entire surface of the ceiling with overlapping roll paper.
2. We fix the bars on top of the paper, the insulation will already lie between them.
3. Cover it all with foil. It will become a normal, safe insulator. But it is necessary to install foil without saving. It is important that all connections are closed.

   The foil layer reflects heat, so the use of such material for a bath is necessary

4. We seal all joints on the foil with aluminum tape. Typically, foil for insulation is included with the material.
5. We secure the edges and joints with several layers of adhesive tape. We check our work for leaks. If there is not enough money for such insulation, then foil is sometimes replaced with cardboard or thick paper without paint.
6. Next, we install layers of insulation on the foil between the closed bars.

   On the ceiling, it is better to lay insulation in two or three layers, overlapping the joints

7. We cover the front part of the ceiling with wood paneling. This material is resistant to elevated temperatures and will not resin.

For a frame bathhouse, it is necessary to put insulation on the ceiling and walls, but for timber and log baths you can do without it. For example, if a bathhouse is made of logs, it is enough to first sew up its ceiling with thick boards - at least 6 cm. Mineral wool is most suitable as insulation for the ceiling - you just need to lay it in a layer of at least 15 cm.

Wall insulation

The best solution for wall insulation is a constructor made from materials that can be easily repaired or replaced.

Bathroom floor insulation

And finally, let's work on the floor. After all, a large amount of heated air usually leaves the room through it. Expanded clay is most often used as insulation for floors - it is an inexpensive and reliable insulation that prevents the formation of mold and condensation.

It’s cheaper, of course, to spill everything with slag, but expanded clay is more environmentally friendly and weighs less. When installing wooden floors, the material is placed between the joists. If a concrete floor is poured, then expanded clay is laid between each concrete layer.

Let's look at the usual cycle of work on insulating a concrete floor.

In addition to walls, floors and ceilings, attention is also paid to the insulation of doors, windows and window openings. They are being processed silicone sealants. External doors are usually insulated with natural materials. And it’s not customary to save on them, otherwise in a few years, or even next season, you’ll have to redo everything.
