What is the name of the insulation with foil, what is it for?

Foil insulation is widely used in the construction of houses, baths and other structures. There are several varieties of such material, each of them has its own name and conditions of use.

What is the name of the insulation with foil

The finishing layer, one side of which is made of foil-clad material, helps to significantly reduce construction costs. The reflective surface collects heat and stores it indoors.

In construction, a multilayer material is used, covered with foil on one or both sides.

The material has a porous base, which serves as a good base for application foil. The upper reflective layer has several varieties:

1. Aluminum foil, which is applied by heat welding. Can be destroyed with cement mortar.
2. Metallized film. More resistant to mortar attack, but less effective at reflecting heat.

Using foil materials for decoration, you reduce the cost of heating the room by 30-60%.

Polyethylene foam

The second name is polyethylene foam. Thickness - from 2 to 10 mm, externally looks like an elastic canvas. Aluminum foil acts as a reflective layer. Manufacturers offer the material in rolls, sometimes it is supplied with self-adhesive elements.

The film is used as an insulating layer under the finishing of the floor, as well as for insulating heating radiators, pipes and other communication objects. It not only keeps you warm, but also protects against annoying noise.

Mineral wool

Another name is stone or basalt wool. In building materials stores, it is presented in a wide range. Available in slabs or rolls, thickness up to 100 mm. It belongs to non-flammable and non-toxic materials, therefore it is suitable for insulating fireplaces and chimneys.

Basalt is used in various premises, including for the arrangement of baths and saunas, attics and floors. Reflection - more than 95%. It is important to know which side to lay the material on correctly.

Glass wool

This type of foil insulation should be handled with extreme care. It has properties similar to those of mineral wool. Eco-friendly and sold at an affordable price.

The danger of glass wool is its ability to spread sharp and prickly dust. Can penetrate the lungs and damage internal organs. When working with glass wool, you must protect yourself with respirators and goggles.

Foil polystyrene foam

A durable material that is sold in the form of slabs. Insulation thickness - from 20 to 50 mm. The base is fused granules. Thanks to this, polystyrene foam is refractory. Preferred for floor insulation. It can withstand high physical pressure as well as high humidity.

Principle of operation and advantages

The foil layer reflects thermal energy and returns it to the interior of the room. In this way, a person significantly saves on heating the house. The material is widely used in the construction of various structures.

The main advantages include:

• efficiency - no more than 10% of heat is lost when interacting with a reflective surface;
• hydro and vapor barrier - the layer is impervious to moisture from the outside;
• ease of installation - builders use a stapler or fasteners, and some manufacturers offer self-adhesive rolls;
• safety - all products meet modern environmental standards;
• long service life - the material is not susceptible to the spread of fungus and does not deteriorate over time, provided that it is correctly installed.

Foil insulation is a high-quality and inexpensive means for insulating various surfaces. When repairing, we recommend using it for finishing floors and interfloor ceilings, water supply and sewerage pipes, as well as for baths and saunas.
