The main feature of a flexible liner for a bath with an aluminum layer - heat retention and rapid protaplivanie premises. If properly used foil, it will serve as a shield between the mirror-walled baths and infrared radiation emanating from fiery furnace. Sheathing can save energy effect.

A few years ago, the installation of the baths was carried out using a simple wooden log cabins and moss. At the same time achieve the effect of a thermos was not possible, the heat pretty quickly evaporated, and had to re-melt bath in a few hours. Today, it is not necessary. During the construction of using high-quality insulation and the insulation film for the pair, so that the room is heated not only faster, but also for a long time it remains suitable for its intended use.

The operating principle of the protective layer

Foil layer - the combined type for room warming bath. One side of this product is made of polyethylene foam, and the other - a polished foil. It is important to ensure that a part of the aluminum was present as he achieved at the expense of preserving and reflecting properties.

The main objectives of foil insulation: water repellent function, the protection of wooden structures from moisture and impact from natural factors - low temperature, strong winds.

Types of foil layers and their characteristics

Foil or paper insulation is very thin and consists of a base layer and aluminum foil. However, for thermal insulation used and other more thick and dense products - foil wool.

Such material also comprises two layers - one size larger - wool, and a second thin - aluminum foil. These layers are laid on the bath floor and walls to protect against moisture and to prevent heat leakage.

Foil in rolls
