Foil insulation for walls: technical characteristics and reviews

Due to its quality and properties, the foil insulation becomes more and more popular every day. It is used as a heat insulation material for floors, noise, hydro and thermal insulation of the attic, roof or walls. It is also used for noise and heat insulation of engineering communications - air ducts, pipelines. It is possible to simply fix the heat insulator sheet behind the heating device in order to increase the volume of supply of heat energy. Excellent he proved himself in the isolation of rooms with high humidity - saunas and baths. Well suited for thermal insulation of entrance doors, which helps to prevent unnecessary heat loss.

Features

This thermal insulation material is a combined laminar product and is a web of pre-expanded polyethylene and polished foil. As a result of combining the properties of these materials, a highly effective thermal insulation of the enclosing structures was provided .

Using a thermal welding, a thin layer of aluminum is applied and polished. Thus, the foil insulation can reflect thermal energy into the room with an efficiency of about 97%. One layer of such insulation, by the value of resistance to heat transfer, can replace brickwork with a thickness of 15 cm.

Due to the thin and cellular structure for this material, water-repellent properties are characteristic, which helps to prevent the formation of condensate, that is, the material has good vapor-insulating properties.

It is also worth noting that the foil insulation has excellent sound insulation properties, and most importantly, is considered an environmentally safe heat insulator.

Types of insulation

The foamed heat insulator does not emit toxic and dangerous substances in comparison with conventional mineral wool .

There are several basic types of this insulation, they differ not only in appearance, but also in functional features, as well as in the field of application.

  1. Foamed polyethylene, covered with aluminum - is used as a thermal insulation of walls and ventilation systems.
  2. Foamed polystyrene foam - is a thick layer of steel color. It is used for floor insulation.
  3. Mineral wool with a layer of foil - is sold in the form of rolls. Perfectly suited this foil insulation for the bath, as well as for insulation of chimneys and roofs.
  4. Basalt foil heat insulator - characterized by high resistance to aggressive media. It can withstand temperatures from -200 ° C to + 700 ° C. Insulation is used in all areas of construction, including the construction of gas stations.

Areas of use

This material is perfect for thermal insulation of the floor, attic and bath. Ideally, this insulation for walls, foil layer will provide a good heat, noise and waterproofing. Many use it to increase the volume of heat output, placing the heat insulator behind the heating devices with the "aluminum" side into the room. Thus, for a small amount of money, you will protect your home as much as possible from excessive losses of heat, frost and wind.

General characteristics

It is a foil-insulated double-layer insulation, which consists of a thermal protective element and an aluminum coating. The aluminum coating is fixed by thermal welding, and then it is polished.

General characteristics of different types of foil insulation:

  • They do not absorb moisture.
  • The heat insulator is resistant to a wide range of temperature differences.
  • The material is resistant to reflection.
  • Heater is easy to install.
  • The foamed insulation foamofol has excellent hydro-, steam- and heat-insulating properties.

Benefits

  1. Foil due to high reflectivity (within 97%) is a good thermal insulator.
  2. Due to its flexibility, this heat insulator can be used for insulation of enclosing structures having a non-standard configuration.
  3. Perfect for such a heater for walls, a foil layer protects them from solar and radon radiation.
  4. Good water-repellent properties prevent freezing and condensation. This quality protects metal frames from rust.
  5. This material has excellent sound insulation performance, it does not require additional chemical treatment, and most importantly, it is environmentally friendly.

Reviews about foil insulation

Despite the fact that foil insulation is a relatively new thermal insulation material, consumers have already had time to appreciate it. This type of insulation allows us to heat insulate building envelopes, which allows us to save considerably on heating in winter, as well as to insulate engineering communications such as air ducts and pipelines.

According to consumers, this insulation has a unique, but rather large drawback - the foil layer is corroded. Although the heater with a metallized coating does not have such a disadvantage, so it can be used in the construction of baths and saunas.

Mounting Features

The following materials are required for installation:

  • Foil insulation.
  • Building stapler.
  • Foil scotch tape.
  • Nails of small size.
  • A hammer.

When carrying out insulation with foil insulation, it is necessary to take into account:

  1. The installation must be carried out by a reflective surface inside the room. This is required to reflect and maintain heat.
  2. Between the finish and the heat insulator it is recommended to leave a distance of about 25 mm, this will create additional heat protection.
  3. When mounted on walls, the heater must be placed in the crate between the rails.
  4. After installation, visible joints must remain. They should be processed with foil tape.
  5. The installation is completed.

Such a heat-insulating material will protect the walls of your house from the formation of condensate, destroying the building and conducive to the escape of heat from the room.

Now warming is available absolutely for everyone. You can independently heat-insulate not only the roof and walls, but also the entrance doors, as well as the space between the wall and the heating device. This is a wonderful, and most importantly, an economical option of how to make your own home warmer and more comfortable. Self-adhesive insulation foil - it is environmentally friendly, safe, high-quality and effective thermal insulation material. Convenient for installation, it will significantly reduce not only your time, but also the cost of heating.

Value for money

The cost of foil insulation is slightly larger than the usual, in this regard, the price - this is one of the main selection criteria. However, one should not get carried away with economy, forgetting about the quality of heat-insulating material.

In the construction market, you can see incredibly cheap foil insulation under the wallpaper. Before you buy it, it is worth considering: how did the manufacturer manage to release such cheap material? In this case, the answer is simple: instead of a real foil, an aluminum sputtering was applied to the heater. The material shines like the real one, but the quality, unfortunately, leaves much to be desired. This is due to the fact that the deposited layer is very thin and is not capable of retaining thermal radiation. As a result, you will pay more than the usual isolation, but as a complete winner. The result is an unjustified overpayment.
