Which foil for a bath is better to choose, according to what criteria

The secret of a warm bath, in the steam room of which steam is stored for a long time, is reliable insulation. The market of modern building materials offers different options for solving this problem. The most successful choice would be insulation with a foil layer. It reliably holds the steam inside, preventing the heat from escaping through the walls.

What is the best foil for a bath?

Range of application foil the bath is quite wide. Before building a structure, it is worthwhile to clearly define the main purposes of all finishing materials. In this case, the bath will last a long time and will delight visitors with a stable temperature and humidity.

Foil in the decoration of the bath creates the effect of a thermos, retaining steam and heat inside the room.

The main purpose of the foil in the bath

The finishing material provides several functions at once:

1. As self-isolation with reflection.
2. As part of an insulating cake.
3. As a vapor barrier.

Thanks to it, it is possible to protect vulnerable materials used in decoration and construction from the effects of heat and moisture. It also ensures that the heat remains indoors.

The effect is achieved due to almost one hundred percent reflection of infrared rays, which are generated by the stove and hot stones.

Foil varieties

Manufacturers offer several types of this material that meet various requirements and are selected in accordance with the conditions of further operation. The main varieties include:

1. Roll. It can also be produced in sheet material. The composition is more than 99% aluminum. For finishing the bath, a finishing foil is sold, which does not imply additional finishing, finishing, as well as a roll that is mounted under the decorative design.
2. Follicle. Laminated paper - this is how this option is often called. It has excellent vapor barrier properties, is quite resilient and strong. There are two varieties on sale: based on natural material with polyethylene and kraft paper. Not suitable for wall decoration around the stove.
3. Foil polystyrene foam. Synthetic material, on top of which the thinnest layer of aluminum is sprayed. This finish creates ideal conditions for keeping warm (more than 98% of the heat remains inside), prevents the formation of cold bridges, provides excellent vapor barrier and is durable.
4. Foil mineral wool. Mats or roll materials can be easily attached to the walls and are easy to cut. Possesses high thermal insulation properties.

Depending on the quality of the building and the raw materials from which the structure is made, select a suitable insulation layer available in stores.

Criterias of choice

The bath assumes rapid heating of the room and long-term preservation of a certain degree of humidity and heat inside the steam room. For these properties, foil insulation is best suited. The main thing is to choose the right material that will solve the problems of the room.

For example, for buildings made of brick, stone and foam concrete, a single layer of foil, fixed directly on top of cold walls, will not work. In this case, you need a serious insulation, on top of which insulation will already be installed. Otherwise, the reflector will not behave in the best way.

When finishing materials vulnerable to moisture, the foil will be an excellent vapor barrier. It will not let the liquid inside the insulation cake, and the finish will last for many years. The result is achieved not due to the thickness of the foil, but due to its reflective properties. More than 95% of heat and moisture "bounces" off the mirror surface, remaining inside the room.

The best foil materials

There are many finishing options for baths today. Manufacturers are constantly working to improve the performance properties of the foil. Among the assortment presented, there are varieties that have earned approval from consumers.

ISOVER "Sauna"

A safe material based on fiberglass, coated on one side with a thin aluminum layer. Does not support combustion, which is important for a sauna. The thermal conductivity is 0.041.

Reasonable cost, improved performance and durability make the material the most demanded among the competitive ones.

SPU Sauna Satu

Differs in ease of installation, withstands high temperature indicators, forms a sealed layer due to the aluminum coating on both sides. Due to its compact size and low thickness, it is preferable for installation in small steam rooms.

Penofol

Reliable and strong material with good thermal insulation properties. For saunas, it is recommended to purchase rolls with a thickness of at least 10 mm. Easy to install and durable, when heated, it does not emit harmful substances into the room.

Folgoizol

Affordable and easy-to-install material that does not deform when fastened. Withstands temperatures over 125 degrees, creates a thin but reliable layer of vapor and heat insulation.

Megaflex

Reduces heat loss as much as possible, creating excellent conditions for bathing procedures. It is mainly used for installation in dry steam saunas. Able to withstand high temperatures and provide a comfortable environment in the steam room.

Before buying foil-clad material, we advise you to look through reviews on the network in order to form your own opinion and take into account the experience of builders.
