Steam room with maximum heating: how to choose a foil for a bath to keep warm
In order for the heat generated from the boiler to remain in the steam room, the bath foil must be used for insulation. How to choose it, what are its performance characteristics and much more in today's publication will tell the editors of homemaster.techinfus.com/en/. You will also learn about the advantages and disadvantages of this material.

Foil layer for a bath: its functions and features
Woe builders have always believed that from foil when arranging a bath no use whatsoever. Nevertheless, this opinion is erroneous, and with the right approach to its installation, you can achieve a special effect.
In fact, foil is a thin layer of aluminum. When attaching it to the walls under the wood sheathing, all the heat generated by the boiler reaches the surface and is reflected back. Thus, all the heat energy remains in the room. This layer is used together with insulation or separately. The corresponding material is capable of reflecting about 97% of the heat generated oven.

When buying foil for a bath, you need to make sure that its canvas is intact, without perforation

Reflector types and performance characteristics
There are several options for foil reflectors, which are usually used when arranging a modern steam room. Let's consider which of them are used in practice, which have operational features.
Izolar craft foil: what kind of material, its characteristics
Kraft foil is a kind of aluminum sheet. It is manufactured with a seal that makes its structure simpler. Differs in the following technical features:
This material variation is very convenient for installation. It is distinguished by increased strength compared to ordinary foil, which has no base.

Usually the material has a pimpled base. Smooth seamy side is occasionally used

Folmot cloth as an option for thermal insulation
Folded fabric is a special structured foil. It is designed for installation in the ceiling area of the steam room. At the heart of the material there is a heat cloth and aluminum foil. The characteristics include:
When heated, this material does not emit toxic substances and an unpleasant odor.
What is roll foil
As a rule, roll foil does not have a reinforcing base. This is a fairly thin material that easily tears and deforms. Its technical characteristics are:
Does not emit toxic substances, and also resists corrosion.
Foil polyethylene foam
The basis of this raw material is foamed polyethylene. They try to use it to retain heat energy in homemade baths and saunas from a wooden frame. Occasionally used for soundproofing cars. The main technical characteristics are as follows:
To fix this material, special metallized tape and wooden slats are used.
Foil polystyrene foam
Material with foil on both sides. Such a coating is able to prevent heat from leaving the room and prevents moisture from entering. Its features are:
However, you should not nail the canvas with nails with a too large cross-section, as this can damage the insulating material and lose its quality.
Foil mineral mat in mats and rolls
Manufactured in the form of slabs and rolls. Differs in increased property of thermal insulation. Suitable for baths, saunas and industrial steam rooms due to its high temperature resistance. Material characteristics are as follows:
Advantages and disadvantages of the material
Foil usually comes with a different type of insulation. It is rational to mount it in combination with glass wool and other denser materials. Subject to these conditions, the material will have the following advantages:

It is better to use only special tape for pasting. Ordinary tape will not support the weight of insulation

Despite the large number of advantages, this material is not without its disadvantages. These should include:
Proper care of the room, its regular ventilation can reduce all the disadvantages to a minimum. Therefore, after each bath, do not forget to open doors, windows and vents.
Which foil manufacturer can you trust
There are a sufficient number of brands on the building materials market that specialize in the production of foil insulation. Among all, three manufacturers can be distinguished.
- Izolon... The concern is located in Izhevsk. Specializes in the manufacture of foils and plastics. For the production of insulation, special technologies are used. The material is produced both sewn and not sewn.
- Penofol... This manufacturer produces thin material with no backing. At the same time, the structure is sufficiently strong and reliable.
- URSA... One of the leading manufacturers in Spain. He produces high quality insulation of various thicknesses and structures. This insulator is also sold in Russia.
When choosing a brand, attention is paid to those brands that promise high quality and compliance with all GOSTs.

Rules for choosing a foil for a bath
Having studied all the possible options and characteristics of foil-clad materials, you can make the right choice. To do this, you need to consider a few simple criteria.
- It is better to give preference to foil with a backing. It is easier to install and more efficient in operation.
- As for the operating temperature, the model of the canvas must have indicators of at least + 100 ° C. Otherwise, in the steam room, the material will begin to deform (fortunately, this is rarely seen).
- When buying, it is advisable to analyze the seller's opinion about the material you like, moreover, you can also read reviews of real users.
- When purchasing a material in combination with a substrate, it is important to be aware of its thermal resistance.
- The permeability of the foil, with or without backing, should be no more than 0.01 g / m².
As for the thickness of the material, it all depends on how much the bath needs insulation. If the room needs to be insulated from the loss of heat energy, then you can do with the usual thin heat-resistant foil.
Foil for a brick bath
Brick walls do not have good thermal insulation, as they have gaps between the seams. For such premises, foil-clad canvas is used throughout the entire area. Fits directly onto partitions. A small space is left, after which the crate and sheathing are made. Therefore, it is better to buy material with a thick backing.
In a steam room with concrete walls
The usual aluminum modification is not suitable here. In this case, it is better to use options with some kind of substrate. This allows you to achieve effective vapor barrier, reduce the risk of dampness in the walls.
Popular insulating foil models
Many people prefer not so much the brand as the version of the material they like. It is often chosen for its external features and performance characteristics. The homemaster.techinfus.com/en/ editorial board offers an overview of decent models.
Foil Installation Tips
It is clear how to attach the foil to the walls of the steam room. However, the following tips should not be neglected.
- For the installation of insulation, it is necessary to install a separate crate.
- Thick enough foil sheets are best glued joint to joint using aluminum tape.
- Damaged canvases must be sealed with the same tape.
- Insulation and cladding should not be done closely. It is important to leave a distance of at least 3 cm between the materials.
- Insulation near the windows must be measured close, and after installation, paste over with sealed tape around the frame perimeter.
Observe the installation requirements and be guided by the performance characteristics of the material when using it. Also ask questions about the topic of the publication and do not forget to rate the article.
