Independent internal lining of the bathhouse using lining, foil

Your own bathhouse is a source of positive energy and health. In order for it to please its owners for many years, it is necessary to take care of choosing suitable insulation and finishing. High-quality thermal insulation allows you to save fuel, and proper cladding creates a favorable microclimate and mood. Wooden lining is the best option for finishing the interior of a bathhouse. The material has healing phytoncides released when heated. A wide range of shades and textures of wood allows you to create a unique interior.

Subtleties of finishing inside the bath

1. Do not mount the lining horizontally in the washing room and steam room. Splashes of water will enter the lock, and the lining will quickly darken. But if the design requires horizontal fastening, then the tenon should point upward.
2. All fasteners must be taken with a zinc coating, since iron will quickly rust if exposed to moisture.
3. All fastening corners and strips at the top need to be slightly sharpened at the bottom, so the water droplets will go down faster.
4. The planks are attached 4-5 cm from the base, so as not to block the ventilated gap.
5. Consider a ventilation system in the bathhouse, so the moisture will evaporate faster and the lining will last longer.
6. If the lining turns black, it must be immediately treated with bleaching compounds, for example, Senezh Sauna

We looked at how to do the interior decoration of a bathhouse with clapboards with your own hands. By following all the techniques and watching the thematic video in this article, even a beginner will be able to do the job with his own hands.

Features and assessment of the feasibility of use ↑

Reflectivity is the main property that makes aluminum foil a suitable insulation for a bathhouse - a room that needs to be heated quickly and strongly. The second argument in favor of choice is resistance to humidity and high temperatures. Not every material can withstand the hot conditions of a steam room.

How to use foil with maximum efficiency ↑

In a bathhouse, foil can be used as an independent reflective heat insulator or as one of the layers in a “pie” with other materials. If you place foil between the thermal insulation layer and the lining, you get the effect of a thermos. This thermal insulation option is ideal for baths made of brick, concrete blocks and those built using frame technology.

Aluminum foil without insulation will act solely as a reflector or vapor barrier, protecting vulnerable materials from moisture. This option is often chosen to increase the air temperature in small steam rooms, as well as to protect wall materials and for fire safety purposes near the stoves.

Advantages and compelling reasons for choosing ↑

Significant advantages of foil for bath insulation compared to other options arise from its unique properties:

• Impermeability to gases and vapors. Even a sheet 0.009 mm thick allows water vapor to pass through in an amount of only 0.01 g per 1 square meter. m of surface during the day, and starting from a thickness of 0.025 mm, gas-vapor permeability is practically zero. The metal atoms are arranged so tightly that only hydrogen penetrates through the network. If we compare any polymer material with foil, its permeability will be the smallest.
• High resistance to corrosion. When exposed to air, the foil becomes coated with oxide, which protects it from exposure to chemicals and greatly prevents corrosion.
• Excellent fire-resistant characteristics. Withstands temperatures up to 145 degrees.
• Environmental Safety. Foil is non-toxic, does not absorb odors, and is not attractive for the growth of microorganisms.
• High reflectance coefficient - from 95 to 98%. This is a screen that both retains heat inside the room and serves as a barrier to the penetration of heated or cold air from the outside.
• Not susceptible to deformation. The canvas can take any shape.
• Good ductility, maintained at high temperatures.
• Resistance to ultraviolet rays, rotting, and the proliferation of pathogenic organisms.
• No harmful fumes.
• Easy to install.

Disadvantages of foil thermal insulation ↑

The advantages of foil for baths and saunas are much greater than the disadvantages, but they cannot be ignored. The following properties can be attributed to the disadvantages:

1. Tendency to gradual corrosion, as a result of which the reflective layer becomes cloudy and the quality of protection decreases. Therefore, when choosing a foil heat insulator for a steam room, pay attention to the presence of a metallized film layer.
2. Limited temperature range, which is why it is necessary to install a ventilation hole to prevent overheating.

To buy high-quality bath foil, you need to choose certified products from manufacturers with a good reputation in the market.

How to sheathe the ceiling correctly?

You need to start finishing the steam room from the ceiling. It is in this part that there is the greatest likelihood of the formation of thermal gaps that exceed the norm, which is unacceptable when constructing steam rooms. The wall panels must be in close contact with the ceiling.

Attaching a wooden board to the ceiling should begin from the entrance side. For installation, nails or a clamp are used. The finishing fastener must support the total weight of the ceiling.

It is quite difficult to secure boards with a metal clamp or an ordinary nail. For this, a special hidden fastening element is used. The head of the nail is cut off and the end board is attached to it.

To protect the front surface of the lining, the nail should be finished off using a hammer. Clean the location of the fastener with sandpaper to prevent the formation of roughness.

The boards must be laid in strict sequence. The distance between the wall of the bathhouse and the ends of the lining should be no more than 40–50 mm. A gap is left to ensure air circulation.

Types of insulators based on aluminum foil

In addition to considerations related to the physics of heat transfer and infrared reflection, the choice of substrate type is related to the ease of installation and mechanical strength of the two-layer material. The foil is easily torn during installation, which requires additional time to seal the gaps with special tape. When paired with a backing, the material becomes much more reliable, which makes it easier to attach it with a stapler to the wooden battens of the sheathing.

Foil insulation for baths

As a strengthening and/or thermal insulation layer, the following is industrially glued onto the foil:

• Mineral wool. The material is produced in rolls with a thickness of 5 - 100 mm. However, not every foiled cotton wool is suitable for arranging baths. In order to increase hydrophobic properties, mineral fibers are impregnated with special compounds that are unsafe for human health when the material is heated. Only insulation without these impregnations should be used with a direct indication of its purpose in the name. For example, "ISOVER Sauna" or "ROCKWOOL Sauna Butts".
• Kraft paper. The main commercial names of the material are “Kraft foil”, “Foil paper”, “Alucraft” and “Isolar”. In Izolar, a third element is added to the aluminum layer and paper - a polyethylene film, which increases strength and serves as a waterproofing layer for the paper layer. The thickness of kraft paper is in the range of 0.3 - 1.0 mm.
• Foamed polyethylene (FPE). The most popular material in the group of foil insulation. Produced under the names "Folgoizol", "Folgoizolon" in rolls with a thickness of 2 - 10 mm and plates (20 - 110 mm). Rolled foil insulation is usually used to equip baths and saunas in log houses without additional thermal insulation. It is produced in large quantities and has good installation and performance qualities combined with a reasonable price.
• Fiberglass mesh. As an infrared screen, a three-layer material “Folar” is sometimes used, containing a reinforcing layer of mesh with a cell of 4x4 mm. The original purpose of the folar is vapor barrier.

We insulate the joints with special tape

A separate group of materials includes PIR slabs, which are formed from high-strength polyurethane foam (PPU) and lined on both sides with aluminum foil. This thermal insulator is available in thicknesses from 30 to 250 mm. It makes sense to use PIR slabs with a thickness of 80 - 120 mm for insulating saunas, baths and hammams in buildings with walls made of brick or concrete. In this case, the slabs play the role of both the main insulation and a layer intended for infrared reflection and vapor barrier. Despite the high price, this material justifies itself on objects intended for long-term use.

Types of lining and classification

Wood paneling

coniferous species

• Pine. The most common wood for lining. It has a beautiful appearance and low cost. Over time, a pine product begins to darken.
• Spruce. Northern spruce is used to make the lining. It is more durable and has a beautiful appearance. Just like pine darkens over time.
• Canadian cedar is used to finish the bathhouse. It is not cheap, but has excellent technical characteristics and a beautiful appearance.

Wood paneling

hardwood

• Oak. Beautiful and durable material, easy to process, expensive.
• Aspen. Beautiful light color. Has thermal insulation properties. Well suited for a bath.
• Linden. It is very suitable for finishing a bath, because the material does not heat up much and emits a pleasant aroma.
• Alder. In a room with high temperatures, the material does not heat up. It also hardly dries out or warps.
• Abash. African oak has high strength and softness. Such wood does not shrink, warp or heat up. Has a beautiful appearance. The cost of abasha is quite high.

Most often, the interior lining of a bathhouse with clapboard is made of hardwood. The temperature in the bathhouse is high and under its influence, coniferous wood releases resins. Hardwoods have virtually no resin compounds, so no resin is released.

The type of wood from which the lining is made is also of great importance. There are 4 main varieties:

• “Extra” is a product made from the highest grade wood without a core or flaw.
• “A” - one live knot, two resin pockets and two blind cracks are allowed per one and a half meters of the length of the product.
• “B” - the presence of four knots (up to 2 cm) is not prohibited, two of which must be captive. Two resin pockets are also possible, one and a half meters long for the product.
• “C” - lining classified in this class allows two captive knots with a diameter of 2.5 cm, non-through cracks of no more than 5% of the length, two resin pockets up to 5 cm long and up to 5 mm wide, mechanical damage up to 6% in diameter, a contrasting spot with a diameter up to 15 cm, as well as other spots and stripes totaling up to 5% of the entire surface of the product.

Also, the lining is divided by type of profile:

• Eurolining.
• Soft-line.
• Calm.
• Imitation of timber.
• Block house (imitation logs).
• Landhaus.
• American.

Construction foil and its characteristics

This insulation has recently appeared on the construction market. It is intended for heat and vapor barrier of premises. The material has high heat-reflecting characteristics.

Most often it is used in combination with other types of insulation and less often as an independent thermal insulation material. It can be installed directly on the walls of the building, as well as on the insulation, leaving an air gap of at least 15 mm between the insulation and the lining.

This heat insulator consists of pure aluminum, due to which it has durability and a high level of heat resistance. The material is distinguished by an ordered network of metal atoms. All of them are very tightly located to each other, and this ensures gas tightness.

Foil is a non-toxic material because it becomes sterile during the manufacturing process. Thanks to this, various bacteria cannot multiply in it.

Aluminum insulation is widely used on many construction sites. It is used as a reflective heat-insulating material in rooms with high temperatures:

• baths;
• saunas;
• water heating boilers and devices;
• air conditioning and ventilation systems.

It is also often used in construction:

• Roofs and ceilings.
• Attics and attics.
• Walls and floors.

Most homeowners use this material for thermal insulation of baths and saunas. Many of them equip these premises with a “warm floor” system using aluminum insulation.

Advantages and technology of using aluminum heat insulator

1. Significant fuel savings for heating the room and minimal heat loss.
2. Speeds up the process of heating the room, since the heat remains inside.
3. Safe for health, since the foil does not emit harmful substances at high temperatures.
4. When exposed to high temperatures, the foil remains in the same state and does not deform.
5. Not afraid of corrosion.
6. Prevents the appearance of condensation indoors.
7. Ease of installation.

Installation of foil is done in several ways. If it is mounted on a wooden sheathing, then you need to secure it with a stapler or small nails. Prepared canvases are also sometimes attached to each other using foil tape.

In order for heat to be reflected most effectively, it is necessary to create an air gap of approximately 3 cm between the foil and the finishing coating. Lining is often used as such a covering in baths or saunas.

Aluminum conducts electricity well, so this fact must be taken into account when installing electrical wiring in rooms. Before using aluminum foil, it is necessary to completely insulate electrical equipment.

In log bathhouses, the fire safety system is most often poorly thought out. For this reason, fires often occur in such a room with a stove. When exposed to high temperatures for a long time, the logs heat up, which leads to fire. Foil attached opposite the stove reflects heat into the room and it practically does not reach the wooden walls.

Aluminum foil for baths and saunas: cost per roll

For a room such as a bathhouse or sauna, foil becomes an indispensable element, and its price is quite reasonable. Its consumption is small, but it can 100% protect the walls of a log bathhouse from mold, flame, and insects.

If the structure is made of concrete or brick, it will allow you to quickly warm up the room and prevent it from cooling down immediately.

• Aluminum foil for baths, 100 microns thick, roll length 10 meters, width 1200 mm and total area of ​​1 roll 12 m2 - cost from 1789 rubles per roll.
• Aluminum foil for baths and saunas, 80 microns thick, roll length 10 meters, width 1200 mm and total area of ​​1 roll 12 m2 - price from 1210 rubles per roll.
• Aluminum foil for a bath, 50 microns thick, roll length 10 meters, width 1200 mm and total area of ​​1 roll 12 m2 - price per roll from 720 rubles.
• Foil for a bath made of aluminum, 30 microns thick, roll length 10 meters, width 1200 mm and total area per package 12 m2 - price for 1 roll is 480 rubles.
• Aluminum foil on a paper base, total roll area 35 m2 - cost per roll from 1205 rubles.

Covering the baths with clapboard

Covering a sauna with clapboard is not something long and requires a lot of experience.

It is recommended to break down all work into stages, which allows you to distribute working time as efficiently as possible and control the timely completion of all previously assigned tasks.

• The first stage, of course, will be preparatory work;
• The second is the creation of a wooden frame for subsequent fastening of the lining strips;
• The third stage is the installation of insulating materials and the installation of the lining itself.
• The fourth and final step can be considered finishing the lining itself, applying a protective layer.

Antiseptic coating for wood - a real opportunity to extend the life of wood finishes

Preparatory work

Before immediately starting work on decorating the walls of the bathhouse with your own hands, it is recommended to carry out preparatory work, which most often includes preparing the walls and ceiling of the bathhouse for further work.

If there are sufficiently deep differences on the walls, at the rate of no more than 2 mm per 1 meter, then work should be done to level the surface. In this case, you can use plaster or putty - the most optimal and inexpensive option.

To increase the level of resistance and durability of the building, as well as to eliminate the possibility of fungus and mold appearing on the walls, most experts recommend applying special protective agents to the walls.

Afterwards, work begins on installing communications, which can include:

• Electricity supply;
• Water supply;
• Everything that can be easily and quickly hidden using wooden panels.

As the last work at this stage, we can note the purchase of direct lining strips and other fastening materials, in particular we are talking about wooden blocks, hangers, and various heat-insulating materials.

The photo shows high-quality installed wiring in the bathhouse

Installation of sheathing

The instructions below will help you understand how to choose the right lathing and how to subsequently lay thermal insulation material between the beams.

To create a frame for the subsequent installation of the lining, you should use only a wooden block, the optimal size is 20x50 mm. When cutting, you can use sizes of 1000 mm in length and 500 mm; also, at your discretion, depending on the type of bath structure itself, you can choose a different ratio of sizes.

Installation of metal hangers on the wall

Afterwards, we install metal hangers; they should be placed at a distance of 30-40 centimeters, while the distance between the rows with beams will be about 40-50 centimeters. We attach the hangers to the wall using dowels. We attach bars for the frame to the pendants.

Laying insulation

Before installing the lining strips on the wall, work is carried out to insulate the bathhouse. Most often, in the process of performing these works, mineral wool is used - as an inexpensive material, but at the same time high-quality and effective, fully meeting modern requirements for creating bath complexes and saunas.

Installation of mineral wool, on top of it a vapor barrier film

On top of mineral wool, it is recommended to install a vapor barrier layer in the form of a vapor barrier film; a wide selection on the market is presented by the ISOSPAN company; these materials help to achieve a comprehensive solution to issues related to the implementation of high-quality heat and vapor barrier of a single room or bathhouse as a whole.

Installation of lining

The process of installing and covering the walls of a bathhouse with clapboard inside can be divided into several main components.

In particular, we are talking about:

• Fastening the lining with galvanized tenon screws. It is recommended to drill holes for self-tapping screws to prevent chipping.
• Start the sheathing process from the most inaccessible place, but remember that the very last board will have to be adjusted both in length and width.

Cladding with clapboard should start from the most inaccessible places

The corners of the rooms are finished with a special wooden plinth, which is secured with stainless nails. Some experts recommend the use of glue when attaching such elements, which is considered by most to be a waste of material and money, since glue is simply ineffective in rooms with high temperatures and constant fluctuations.

How to properly line a bathhouse with clapboard using nails as fastening material

How to choose the right foil

To decide on the type of foil product, it is important to take into account the material that was used in the construction of the bathhouse, as well as the conditions of its use. If the steam room was built from logs with caulked walls, it does not need thermal insulation

When wood is used in the construction process, and the bathhouse is large in size, the room warms up gradually, so the structure requires an additional layer of thermal insulation made of thin foil, which is then covered with clapboard.

A foil sheet attached to the heating system is also suitable. Thus, the steam room will warm up faster.

If the steam room was built from foam blocks, it is considered that such a bath is warm and does not need additional thermal insulation. But in this case it is necessary to install a vapor barrier layer. In this case, foil will be the optimal solution.

Brick structures need insulation first. Here experts recommend using foil with mineral wool or expanded polystyrene insulation. The type of material is selected taking into account the thickness of the floor and the presence of an attic space.

In addition, if the steam room is used rarely and for a short time, it does not need lining. Otherwise, thermal insulation will help conserve precious heat and save on heating costs, allowing the room to heat up very quickly and cool down gradually.

Covering saunas and baths: what's the difference?

Bathhouses and saunas differ in humidity and temperature.

In the sauna, the air is dry with humidity up to 8% with a permissible temperature range of 80–140 degrees.

In the Russian steam room, high humidity is always maintained with an indicator of up to 70%. In this case, the maximum permissible temperature is up to 100 degrees.

There are no restrictions on the choice of tree species for sauna cladding, with the exception of pine. Raw materials are less susceptible to moisture and therefore last longer. Installation method: vertical, horizontal.

For lining a Russian bathhouse, it is better to take lining made of alder, linden, abasha, and larch. The combination of several breeds at the same time looks beautiful. The installation method is predominantly horizontal.

What is the purpose of foil?

To achieve effective energy saving in a bathhouse, you will need to not only insulate it, but also use reflective material in the form of a special foil film. Masters claim that it helps return up to 95% of the heat into the room.

The result is that fuel for the stove is saved and the duration of the fire is reduced.

For baths, aluminum foil with a thickness of 30–300 microns is used. It is used in combination with other insulation or is already fixed as its top layer.

Therefore, before covering, they first attach insulating material to the walls and ceiling, thanks to which the heat does not escape beyond the bathhouse. An insulated steam room heats up faster and retains heat longer.

The following are the advantages of foil:

1. It acts as a vapor barrier and blocks the access of moisture to the insulation. The generated steam remains on the walls of the steam room.
2. Its service life exceeds 50 years. Wooden elements will begin to rot faster than the foil layer will deteriorate.
3. Excellent sound insulation. Foil can absorb up to 70% of all sounds and noise.
4. Fireproof raw materials. Does not burn. It will become an obstacle to the spread of fire.
5. Bathrooms warm up faster and take longer to cool down.
6. If you fix the insulation with a foil layer, then the foil will prevent it from falling off.

Among the disadvantages, the following should be noted:

When there is a difference in temperature outside and indoors, condensation appears on the surface of the material. It is important to leave a gap for ventilation before covering. If this is not done, the resulting condensate will begin to be absorbed into the sheathing, which will lead to rotting of the lining. Foil has poor throughput

As users say, she is not breathing. Therefore, the rooms must have good ventilation, both forced and natural (windows, doors). Aluminum particles accumulate in the lungs, causing various respiratory diseases. But if you use the sauna periodically, the risk of harm to health is minimal.

What materials to choose for insulating the walls of a bathhouse from the inside?

Bath insulation on walls with foil

Well suited for baths, because... performs several functions at once (hydro- and vapor protection, heat-insulating properties). There are several types depending on the foil material:

1. with a layer of foil;
2. with aluminum coating;
3. with a layer of aluminum foil.

Regular foil can be subject to corrosion, and aluminum must be protected from excessive overheating, otherwise it can damage the finishing materials.

Classic mineral wool

We recommend not using this type of insulation, or limiting the scope of application by excluding the steam room.

When heated (and this process is always typical for a bath), this material begins to release phenol-formaldehyde resins, which act as a binder in mineral wool. The negative impact of these resins on human health has been proven.

Basalt wool

It is low cost, fireproof, and easy to install. It can be classified as an environmentally friendly material; in addition, basalt wool has good sound insulation. The disadvantages include the tendency to shrink (over time the layer will become thinner) and the fact that it becomes dusty during installation.

Foam glass

Foam glass would be an ideal option, if not for its high cost and heavy weight. It is absolutely harmless and safe, not susceptible to shrinkage, insects and rodents. It is a fireproof material. It must be installed together with a vapor barrier, otherwise the walls will be damaged by fungus, mold, etc. The difficulty of installation lies in the fact that if the installation technology is violated, there is a high chance of destruction of the material.

Useful video

Watch a video about the advantages of this modern material:

Peat blocks

They are crushed peat, which is formed into blocks of various sizes and shapes. Combines heat and sound insulating properties. It has bacteriological properties and is not subject to burning or rotting. It is considered an environmentally friendly and breathable material.

A small disadvantage is that this option is not very common and at the moment there are quite a few companies producing it.

Ecowool

Thanks to the flame retardants included in the composition, it is classified as a fireproof material. And cellulose gives the right to classify it as an environmentally friendly material. The difficulty is that the most effective method of application is “wet”, and it requires certain skills and specialized equipment. In addition, ecowool is very hygroscopic and is not suitable for use in a bathhouse.

Foil polyurethane foam

Another insulation for a bath on the walls with foil. It is one of the most modern materials, has an aluminum coating on one or both sides, and performs shielding and waterproofing functions.

A slight difficulty seems to be that specialized glue is not always able to hold the sheets on the walls, and breaking through the material is contraindicated. Otherwise, the heat-insulating layer will be destroyed.

CAREFULLY! You may decide not to use it due to doubts about its environmental friendliness and the release of gases when heated. Like the following materials

Polystyrene foam and polystyrene foam

We strongly recommend excluding these materials from the list of suitable insulation materials, because when heated (more than 60 degrees) it begins to release harmful substances. And then the healing procedure takes on the opposite character.

So, we have comprehensively examined the topic of insulation for bathhouses on the walls from the inside. The choice of insulation materials is huge and many of them are suitable for use in bathhouses and steam rooms without danger of harm to human health. In addition to industrially produced materials, do not forget about natural insulation materials, for example, mixtures with clay.

The most important thing is to correctly install all the elements of the “pie”, not forgetting about ventilation gaps and the use of steam and water protection. And it’s worth completing the work on the internal insulation of the bathhouse with finishing materials that can be coated with special compounds or oils to maintain a beautiful appearance. In this case, you will get an excellent bathhouse in which it will always be pleasant to take a steam bath.

Features of finishing material

Cladding with clapboard over a foil layer
A special microclimate is created in the bathhouse and sauna, characterized by increased temperature and humidity. To finish them, you need a material that can withstand such conditions, is aesthetically pleasing and safe. The best option is wood. Finishing the bathhouse with clapboard will provide comfort, healing phytoncides and attractiveness of the interior. The material has low thermal conductivity, does not burn the body on contact, and dries quickly.

Lining is a thin board with a longitudinally located tongue and groove. After assembly, there are no cracks or gaps left on the surface. One of the varieties of lumber is eurolining. The slats have 2 grooves on the back side, which serve to remove moisture and prevent deformation when drying. They are made only from dried lumber, the tongue-and-groove joint is characterized by an increased size - up to 8 mm. The use of eurolining improves the ventilation properties of the cladding, its durability and quality.

Advantages of using lining in a bathhouse:

• The material is environmentally friendly and safe; under the influence of high temperature, substances beneficial to health are released.
• Decorative appeal of the cladding, wide possibilities for decoration.
• Resistance to moisture, temperature fluctuations and mechanical damage.
• Availability of installation on your own without the involvement of specialists.
• Long service life without loss of performance characteristics.
• Excellent heat and sound insulating properties.

The cost of material per square meter depends on the type and type of wood. Rare wood (Canadian cedar, oak, abash) will cost more, but it has excellent performance characteristics. Budget options (pine, spruce, aspen) are more popular due to their affordable cost.

Methods for attaching lining to the wall

Listed below are the 5 main ways to attach lining to a wall.

The simplest and most convenient way that does not require specialization. Installation in progress

using small nails and clamps

. In this way, it is permissible to fasten only light lining, because the grips are not capable of holding a lot of weight.

A clamp is inserted into the lining, which is attached to the guide rail using a nail, screw or self-tapping screw. A rail is inserted into the groove and each subsequent rail is fastened in the same way. They must be fastened tightly enough so that there are no gaps. If the last row of lining does not fit entirely, and a large gap remains, then the top row must be cut to size and secured along the guides.

Using nails

. It may seem that this method is simpler than the previous one, but in practice chips, bruises and other damage to the material often occur. In addition, the process of performing the work is not very convenient and labor-intensive. Nails are driven in every 25 - 30 cm. To install a two-meter long slats, 7 or 8 nails are needed.

First, the panel is marked in the places where the nails will be driven in. Then, at an angle of 45 degrees, the nails are nailed into the edge with the groove. The panel is applied to the wall and then you can drive in nails. After installation, the caps are recessed so that the next panel of the lining easily fits into the groove. After this, the next panel is installed using a similar method.

This installation method cannot be used for thin lining, as it will break off.

This mounting option is used

for old-style lining

. Cladding with eurolining is somewhat different from installing older lining. The design of the product consists of fastening with screws. To avoid splitting the wood, a hole is drilled in the places where the screw is screwed in. The drill should be smaller in diameter than the screw. The hole location is countersunk to recess the screw head. The fasteners are screwed in as far as possible using a screwdriver. The caps will not be visible because they are covered by the next row of panels.

Installation of lining

using a stapler and construction staples

. The bracket is driven into the groove at an angle of 45 degrees. You need to have a stapler that can push the staple tightly in until it stops. In this case, the fasteners will in no way interfere with the installation of the next row of panels.

The fifth method of fastening is most often used

for finishing a sauna or bathhouse

. Screws act as fasteners. A hole is drilled at the installation sites and the fasteners are screwed in using a screwdriver. The screws are tightened to the point where the head is significantly recessed. To hide the heads of the screws, a plug is driven into the hole where it is screwed in.

Over time, under the influence of high temperatures, the wood may dry out a little, and the locations of the plugs will appear. To prevent this problem, special compounds must be applied over the plugs.

Preparatory work for wall cladding

Before quickly sheathing the inside of the bathhouse with aluminum foil and wooden clapboard, it is necessary to insulate the walls. Before laying the insulation, install the counter-lattice and sheathing. A layer of vapor barrier is laid on top of the insulation.

Thermal insulation device

The best material for insulating baths is basalt wool. This material has good thermal insulation and a high degree of fire resistance. Basalt wool does not rot. This type of insulation does not burn and does not emit harmful substances. Basalt can withstand temperatures up to 1500° C.

Experts recommend using Rockwool brand “Light Butts” mineral wool. The mineral wool of this company is of high quality, increased density and affordable price.

To cut basalt wool sheets, large, sharp knives with a high-quality blade are used. When cutting, the knife blade is held at an angle of 30-45° to the surface of the blade. When tilted, the blades dull much more slowly.

The width of the canvas is taken to be 2 cm greater than the distance between the vertical posts of the sheathing. The increased width helps to fix the blades in a constant position.

Thermal insulation sheets are laid in 3 layers with overlapping joints. The amount of overlap is equal to half the length of the canvas.

All layers are laid in height within one span of the sheathing. The laying direction is from floor to ceiling. They move to another span after laying all the layers of the previous span.

Laying the first layer begins from the floor. First, the whole canvas is laid. After laying all the canvases of the first layer, the second layer is laid.

Laying the second layer also begins from the bottom. For overlapping joints, the length of the first web of the second layer is taken equal to half the length of the standard web.

At intersections with obstacles, elements of the required shapes and sizes are cut out.

Before covering the bathhouse with clapboard, care should be taken to protect the walls from dampness and rotting. Therefore, after installing thermal insulation, they begin to install the vapor barrier material.

Vapor barrier device

The vapor barrier layer is designed to protect walls from condensation and increase the heat-reflecting properties of the insulation.

The work of laying vapor barriers is the most critical when constructing bathhouses. The efficiency of steam use depends on the quality of vapor barrier work.

Aluminum foil with a thickness of 50-80 microns is used as a vapor barrier. Attaching the foil begins from the corner of the room in the direction from bottom to top.

Vapor barrier sheets are sewn with metal nails or staples to the vertical posts of insulation cells. To attach the foil, use a pneumatic gun or a special construction stapler.

The foil is laid with an overlap of 2-3 cm of vertical seams. All seams are taped with aluminum adhesive tape.

In places of transition from the walls to the floor and ceiling, the foil is laid with an overlap of 5-10 cm in each direction. The free ends are sewn to the ceiling and floor with nails or tacks.

At the junctions of walls and ceilings, gaps often appear in the foil. To eliminate these gaps, use foil corners. To make such a corner, a piece of foil is placed on the corner of a table or chair.

The resulting shape is carefully beaten with a light object to soften the foil. Broken corners are glued with aluminum adhesive tape

The manufactured corner is inserted into the corner and carefully taped.

After completing the work, check the quality of the vapor barrier installation. Any damage found is covered with adhesive tape.

After installing the vapor barrier, the installation of the counter-lattice begins.

Counter-lattice device

The counter-lattice serves as the basis for the main sheathing. Designed to ensure air exchange in the space between the foil layer and the lining.

To construct the counter-lattice, wooden blocks with a cross-section of 20x20 mm are used. The bars are nailed to the vertical posts of the insulation cells. The distance between the slats is taken to be 400-500 mm. Installation of counter-lattice slats is carried out according to level and plumb.

When installing a counter-lattice, a hole with a diameter of 80-100 mm is drilled in the ceiling for the exhaust duct pipe. A sealing cap (valve) is inserted into the hole. During bath procedures, the hole is closed. To ventilate the bath after washing procedures, the hole is opened.

Periodic ventilation prevents the appearance of dampness and rotting of the lining. To ensure air exchange, a gap of at least 2 cm is provided between the lower end of the lining and the floor.

Subtleties of finishing inside the bath

1. Do not mount the lining horizontally in the washing room and steam room. Splashes of water will enter the lock, and the lining will quickly darken. But if the design requires a horizontal fastening, then the tenon should point upward. All fasteners must be taken with a zinc coating, since the iron will quickly rust with moisture. All fastening corners and strips at the top need to be slightly sharpened at the bottom, so water droplets will go down faster .The planks are attached 4-5 cm from the base, so as not to block the ventilated gap. Consider a ventilation system in the bathhouse, so the moisture will evaporate faster and the lining will last longer. If the lining turns black, it must be immediately treated with bleaching compounds, for example, Senezh Sauna

We looked at how to do the interior decoration of a bathhouse with clapboards with your own hands. By following all the techniques and watching the thematic video in this article, even a beginner will be able to do the job with his own hands.

Wooden cladding of walls and ceilings in a bathhouse is a traditional finishing option that allows you to accumulate heat in the premises and create an optimal microclimate for bathing procedures and relaxation.

Principles of insulation depending on the type of building

The choice of insulation depends on the material from which the bathhouse is built. We need to talk about each type of building in more detail.

Made of brick

Sheathing with foil and clapboard is usually done in brick baths. Carrying out work:

1. Without additional insulation of walls, ceilings, and in brick baths, it is impossible to achieve an optimal level of comfort.
2. All brick surfaces are covered with foil. The individual sheets are glued together with metal tape.
3. The sheathing needs to be secured over the reflective sheets. It must be independent so that there is good ventilation between the wooden frame and the foil layer.

If there is no ventilation, condensation will accumulate inside, which will cause the wooden frame to rot.

Made from concrete

To insulate concrete surfaces, ordinary foil will not work. You need to choose a material that has a backing. It is fixed on top of the waterproofing layer.

Made of wood

It is not necessary to cover wooden beams with foil. To achieve an optimal level of comfort, it is enough to correctly caulk the seams between the logs. You can cover the ceiling in the steam room with foil. It needs to be secured with the reflective layer down, the sheets overlapped, and glued with aluminum tape.

Classification of lining

Depending on the material used, lining can be divided into several types.

Plastic

The plastic type of the material makes it possible to save money, and we are also pleased with the simplicity of how the lining is attached to the wall. This lining is suitable for both ceilings and walls; moreover, it looks aesthetically pleasing and fits almost seamlessly. One of the disadvantages of the material is its short service life, since it fades in the sun and cracks in frost.

Metal

Such panels are usually made of steel and aluminum, which have an additional layer of protective coating. The texture and color scheme can satisfy the needs of even the most demanding buyer. Aluminum products are made to last and are ideal for outdoor work. As for steel, if the integrity of the protective coating is damaged, corrosion processes may begin and the metal will begin to rot.

What is the difference between regular and eurolining

Both options are suitable for high-quality surface finishing, but eurolining has additional advantages:

• Euromaterial is made from other types of wood and using other processes in manufacturing technology.
• It has an elongated groove for fastening.
• Other geometric parameters are inherent.
• The products go through excellent drying and special processing.
• Eurolining is characterized by an additional ventilation function.
• There are systems for removing accumulated moisture, and this helps protect the wood from destructive processes (special grooves are made on the back side of the panel so that the aesthetics of the wood are not compromised).
• It differs in cost (it is higher than that of standard lining).

Step by step guide

To do the work correctly, it is important to observe some nuances. Before proceeding directly to the sheathing, wooden planks are fixed along the vertical surface

Subsequently, they will play the role of a frame for attaching the material. A layer of insulation is placed between them. Thermal insulation is laid, aluminum tape must be glued at the joints

Before proceeding directly to the sheathing, wooden planks are fixed along the vertical surface. Subsequently, they will play the role of a frame for attaching the material. A layer of insulation is placed between them. Thermal insulation is laid; aluminum tape must be placed at the joints.

You can attach the lining to the foil with a fifteen-centimeter air gap. This step is necessary for efficient heat transfer.

Thanks to the air gap, the thermal conductivity of aluminum decreases; infrared rays hitting the foil sheet will reflect heat into the steam room.

You can also consider more detailed instructions for covering.

Log steam room

If the walls are built from logs, covering with foil is pointless. In this case, the quality of caulking is much more important. The thermal insulation layer on the log house will not play a role. In a log steam room, foil may only be used to cover the ceiling surface. In addition, aluminum foil is used to decorate the walls around the heating device. This way the heat will be reflected into the room rather than heating up the back wall.

When working with the ceiling, the foil is attached with the reflective layer down, overlapping, extending up to 5 centimeters onto the walls

It is important to seal the joints with special tape. The work should be done efficiently, without creating loopholes for steam

If desired, cover the top of the foil with clapboard, but you can leave it like that.

Brick steam room

When using frame technology or brick, it is important to follow a step-by-step guide, which includes covering the entire area of ​​the ceiling and walls with material. Creates a thermos effect

1. The master marks the wall onto which the sheathing bars are attached, the thickness of which must correspond to the thickness of the insulating layer, since it will be laid between the beams. If the lining is subsequently attached in a vertical position, the planks are secured in the same way.
2. The width between the beams should be equal to the width of the insulation product. If there is ventilation or windows on the surface, bars are attached around them, onto which the foil will subsequently be attached.
3. The insulation material is placed.
4. It is covered with foil and secured to the sheathing with a construction stapler. Material with a small thickness should be laid with an overlap, but if it is thick, the material is attached end-to-end. Around windows and ventilation, the work is done more carefully.
5. The joints are covered with metallized tape. They must be hermetically sealed.
6. Slats with a thickness of about 25 mm and a width of 4 cm are attached to the sheathing. They will act as a retainer for the foil with insulation, create a gap and become a support for further installation of the lining.
7. At the final stage, the lining is attached to the sheathing. When attaching the planks horizontally, you need to start from the bottom; they are placed with the grooves down. For vertical fastening, installation is performed from the corner, leveling the first element.

Work with the ceiling is done in the same way. You need to fill the baseboard around the perimeter.

Decorating the rest room

The bathhouse is always perceived as a place of relaxation from everyday worries. Each room in it is intended for its own purposes. The name of the relaxation room speaks for itself: this is where you relax after water treatments

Therefore, it is important to create a cozy and relaxing environment in it.

Proper finishing of a relaxation room in a bathhouse is not an easy task, the implementation of which can be entrusted to specialists: designers and artists.

A cozy environment is created through the correct choice of facing materials, furniture, accessories, organization of lighting and illumination of various zones and architectural elements of the room.

Reflective insulation installation technology

When insulating a bathhouse with foil with your own hands, work begins with thermal insulation of the ceiling, then moves on to the walls.
These two stages have their differences, although they are basically similar to each other. General recommendations for installation
1. It is important that the reflective layer of aluminum foil is oriented towards the interior of the room.

2. Fixation is carried out directly to the wooden planks using staples or nails. If the width of the canvas is large, it is secured both at the edges and in the middle.

3. There should be an air gap between the foil and the covering material, which will reduce the thermal conductivity properties, and the maximum number of rays that fall on it will return again to the bathhouse or sauna room.

4. Particular attention should be paid to joints to eliminate cold bridges

Sequence of work on ceiling insulation

The temperature is maximum under the ceiling, therefore, heat loss through it is large. When mineral wool plays the role of insulation, the installation of foil on the ceiling should be performed in the following sequence:

1. Cover the ceiling with rolled paper.

2.Make a sheathing from wooden slats. The thickness depends on the choice of insulation.

3. Place roll or slab insulation between the sheathing elements, securing it with temporary strips.

4.Proceed with installation of the foil. It must be laid with an overlap of 20 to 25 cm and an overlap on the walls.

5. Apply metallic tape at the joints to create the most airtight coating.

6. Stuff 50 mm thick battens over the top.

7. Treat the nails you are going to use to attach the trim with a special compound that protects them from corrosion. Cover the wood on all sides with waterproof varnish - this will extend its service life.

8. Install the finishing material. An air corridor will remain between the foil and the finish, equal in height to the thickness of the slats, which will ensure good air convection.

9. Cover the area around the chimney with asbestos. Do not install insulation close to the pipe.

Installing foil insulation on the ceiling greatly simplifies the process. It is simply cut into pieces of the required length and mounted end-to-end on the ceiling. Heat-resistant tape is used to seal the joints.

Which lining to choose for a bathhouse

There are 4 types of lining, differing in the profile of the boards:

1. Eurolining.
2. Standard (otherwise called “peasant”).
3. Block house (imitation logs).
4. American (imitation timber).

Popular brands that have proven themselves to be of high quality:

• "Calm";
• "Soft Line";
• "Classical".

All of them belong to the eurolining category and differ in size and profile. Boards, regardless of their type and brand, are often called lamellas.

Finishing a bathhouse with clapboard is a traditional, frequently used solution. It has gained so much popularity for many reasons. Lining is a natural and therefore environmentally friendly material that is beneficial to human and animal health.

When choosing, it is extremely important to consider several points:

• type of wood;
• grade of material;
• resistance to moisture;
• coefficient of thermal conductivity.

The principle of a thermos for thermal insulation of a bath

During operation of the furnace, up to 80% of the heat is transferred by infrared radiation; up to 20% - due to the thermal conductivity of air, surfaces and objects located in the steam room; up to 7% - due to convection (mixing layers of air). That is why the role of the infrared screen is becoming in demand. This is what foil for the bath does, which is produced by industry in the form of a single-layer material, or as part of a two- or three-layer sandwich.

What does heat reflection do?

The use of flexible cladding with a glossy aluminum layer allows you to heat the steam room faster and retain heat longer. Foil for bath insulation acts as a mirror, reflecting the intense infrared radiation of the stove arches back into the room. Skeptics believe that this is only possible in one case: if you do not cover the foil with casing. They are wrong. The lining reduces the percentage of reflected heat rays, but when heated from the back side of the foil, the lining becomes a much less thermally conductive material. The design of the thermos thus changes, but the overall energy effect remains the same.

Illustration of the principle of heat reflection from foil material using the example of Alucraft products

What ensures that the cooling of the bath slows down? After all, the foil does not affect the thermal conductivity of walls located outside of it. In this case, other physical laws apply. The heat reflector promotes more uniform heating of air, surfaces and objects in the room. Heat transfer works from more heated bodies to less heated ones. By reducing the temperature difference, we thereby reduce heat transfer.

Why is foil glued to the insulation layer?

If the heat-reflecting material is placed without direct contact with the thermal insulator, then an air layer is formed behind the infrared mirror, heated by heat transfer through the foil. This layer will transfer heat towards the street. Therefore, no matter what kind of bathhouse you are going to equip - chopped, brick or with concrete walls - there is no point in using foil without insulation.

Insulation of a log bath

Another question is whether an additional layer of insulating material is needed? In log houses, it is enough to use thin bath insulation with aluminum foil. foil sandwich. Log baths do not require any other insulation, except for inter-crown gaskets and caulking of seams. Infrared mirror technology is economically feasible in any steam room, but stone walls require thorough thermal insulation using wool or slab materials, the effect of which cannot be replaced by foil-based coatings.

Algorithm for interior finishing

Walls

Finishing work begins with the walls. It is necessary to take into account that their list and sequence, as well as the materials used, will differ for the main premises for various purposes (steam room, washing department and dressing room).

It is better to finish the walls in the steam room with wooden paneling. The optimal choice is linden or aspen. As a last resort, birch trees.

In the washing department it is possible to use lining with a moisture-resistant coating, plastic panels or tiles. For a log bathhouse, the optimal solution is to use wood.

The walls of the dressing room (rest room) can be finished with any materials.

The sequence of work is as follows:

• The lining is left inside the bathhouse for a day to adapt the material to temperature and humidity. this reduces the likelihood of deformation;
• lay electrical wiring;
• perform caulking of all inter-crown seams (moss, tow, special hemp or jute edging, flax-jute insulation);
• steam and waterproofing is performed;
• the sheathing for the lining is installed;
• insulation is installed (the optimal solution is basalt wool);
• the lining is sewn on (an air gap is left).

In the washing department and dressing room, it is additionally treated with antiseptics and fire retardants.

Floors

Work begins with cutting off the subfloor and organizing ventilation of the foundation. This will minimize condensation on subfloors. The floors in the steam room and washing area are made with a slight slope towards the sewer holes so that the water flows there by gravity.

The steam room has wooden floors. The optimal solution is a tongue and groove board. This allows water, even when they are tightly packed, to go into the sewer. And ensures high-quality drying.

If financial possibilities allow, then you can install a cork covering on top of them (the feet do not slip and it looks amazing).

The floor surface in the steam room should be raised above the ground higher than in the rest room and washing area.

In the washing room it is recommended to place porcelain tiles, on top of which there is a wooden slotted panel. This will not interfere with the drainage of water and will prevent slipping.

Which thermal insulation product is better?

Due to their characteristics, bath insulation has different properties; with foil they will cost more, but this is a justified expense. It is difficult for the average person to figure out at first what product is better, more reliable, what are the properties of thermal insulation foil, how much does 1 sq.m. cost. product for insulation. The table below will help you save time when choosing foil for your bath.

Installation of foil thermal insulation cannot be called too labor-intensive. If the steam room is made of logs or wooden blocks, then the foil can be attached directly to the wall in the bathhouse. The whole process is carried out in several stages: Rules for installing foil insulation

Thermal insulation is attached to the wall with special construction brackets

It is important to monitor the integrity of the canvas and avoid tears. If it was not possible to avoid damage, then metallized tape will help correct the situation. The insulation is attached with an overlap, the width of which should be at least 20 cm

Each joint is taped with special tape. The better this work is done, the less heat loss there will be in the future. A frame is mounted on top of the insulation for finishing. It is important to pay attention to one point: it is necessary to maintain a gap between the finishing panels and the insulation to ensure air circulation.

If the walls are made of brick, then, as a rule, installation is carried out on top of mineral wool. To complete this process, the procedure changes slightly. Then, first of all, you will need to assemble the frame of the future partition, and mineral wool is laid inside this frame, on top of which foil is mounted in the usual manner.

The process of insulating any room, including a bathhouse, is an important stage in the work. Not only the consumption of energy sources, but also the safety of building structures, as well as indoor comfort, depend on how well the work is done and how effective the materials are selected. Nowadays, materials for thermal insulation can be chosen from a huge number of products on the market.

It is important to know that foil for insulating baths is an integral part of the process of creating optimal operating conditions in the future

When building a bathhouse, the main task is to create a structure that will quickly warm up and retain heat for as long as possible. For this purpose, the walls and ceiling are insulated. Aluminum foil for baths is most often used as insulation. There are several types of this material, differing in strength, ease of installation, durability and service life. When choosing a specific type of foil insulation, you need to focus on the characteristics of the building.
