Due to its quality and properties, foil insulation is gaining more and more popularity every day. It is used as a heat-insulating material for floors, noise-, hydro- and thermal insulation of the attic, roof or walls. It is also used for noise and heat insulation of utilities - ducts, pipelines. You can simply fasten the heat insulator sheet to the heating device in order to increase the supply of thermal energy. He proved himself to be excellent when isolating rooms with high humidity - saunas and baths. It is well suited for thermal insulation of entrance doors, which helps prevent excessive heat loss.
Features
This heat-insulating material is a combined layered product and is a sheet of pre-foamed polyethylene and polished foil. As a result of combining the properties of these materials, high-performance thermal insulation of building envelopes was provided .
Using thermal welding, a thin layer of aluminum is applied and polished. Thus, foil insulation is able to reflect heat into the room with an efficiency of about 97%. One layer of such insulation, according to the value of heat transfer resistance, can replace brickwork with a thickness of 15 cm.
Due to the thin and cellular structure, this material is characterized by water-repellent properties, which helps prevent condensation, that is, the material has good vapor barrier properties.
It is also worth noting that the foil insulation has excellent soundproofing properties, and most importantly, it is considered an environmentally friendly heat insulator.
Varieties of insulation
Compared to conventional mineral wool, a foil-based heat insulator does not emit toxic and dangerous substances.
There are several main types of this insulation, they differ among themselves not only in appearance, but also in functional features, as well as the scope.
- Foamed polyethylene coated with aluminum - used as thermal insulation of walls and ventilation systems.
- Foamed polystyrene foam - is a thick layer of steel color. It is used for thermal insulation of the floor.
- Mineral wool with a layer of foil - sold in the form of rolls. This foil insulation for a bath, as well as for insulation of chimney pipes and roofs, is perfect.
- Basalt foil heat insulator - characterized by high resistance to aggressive environments. 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. This insulation for walls is ideal, the foil layer will provide good heat, noise and waterproofing. Many people use it to increase the volume of heat output, placing the heat insulator behind the heating devices with the "aluminum" side in the room. Thus, for little money you will protect your own home as much as possible from excessive heat loss, frost and wind.
General characteristics
It is a foil insulation two-layer insulation, which consists of a thermal element and an aluminum coating. The aluminum coating is fixed by thermal welding, and then polished.
General characteristics of various 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.
- The heater is easy to install.
- Foil insulation foam foam has excellent hydro-, steam- and heat-insulating properties.
Benefits
- Due to its high reflectivity (within 97%), the foil is a good thermal insulator.
- Due to its flexibility, this heat insulator can be used for insulation of building envelopes having a non-standard configuration.
- Such a heater for walls is perfect, a foil layer will protect them from solar and radon radiation.
- Good water repellent properties prevent freezing and condensation. This quality protects metal frames from rust.
- This material has excellent soundproof performance, it does not require additional chemical treatment, and most importantly, it is environmentally friendly.
Reviews of foil insulation
Despite the fact that foil insulation is a relatively new thermal insulation material, consumers have already managed to appreciate it. This type of insulation allows you to qualitatively insulate the building envelopes, which can significantly save on heating in the winter, as well as insulate utilities such as ducts and pipelines.
According to consumers, this insulation has a unique, but rather large drawback - the foil layer is susceptible to corrosion. Moreover, a heater with a metallized coating does not have such a drawback, so it can be used in the construction of baths and saunas.
Mounting Features
For installation, the following materials will be required:
- Foil insulation.
- Construction stapler.
- Foil tape.
- Small nails.
- Hammer.
When performing insulation with foil insulation, it is necessary to take into account:
- Installation should be carried out with a reflective surface inside the room. This is required to reflect and retain heat.
- It is recommended to leave a distance of about 25 mm between the finish and the heat insulator, this will create additional heat protection.
- When mounting on walls, the insulation must be placed in the crate between the rails.
- After installation, visible joints should remain. They should be treated with foil tape.
- Installation completed.
Such a heat-insulating material will protect the walls of your home from the formation of condensation, which destroys the building and contributes to the release of heat from the room.
Now warming is available to absolutely everyone. You can independently insulate not only the roof and walls, but also the entrance doors, as well as the space between the wall and the heater. This is a wonderful, and most importantly, economical option on how to make your own house warmer and more comfortable. Self-adhesive foil insulation is an environmentally friendly, safe, high-quality and effective heat-insulating material. Convenient for installation, it will significantly reduce not only your time, but also heating costs.
Value for money
The cost of foil insulation is slightly more than usual, in this regard, the price is one of the main selection criteria. However, do not get too carried away with saving, forgetting about the quality of the insulating material.
In the construction market, you can see incredibly cheap foil insulation for wallpaper. Before you buy it, it is worth considering: how did the manufacturer manage to produce such cheap material? In this case, the answer is simple: instead of real foil, an aluminum spray was applied to the insulation. The material shines the same as the real one, but the quality, unfortunately, leaves much to be desired. This is due to the fact that the sprayed layer is very thin and is not able to retain thermal radiation. As a result, you will pay more than for ordinary isolation, but you will not win at all in quality. The result is an unjustified overpayment.
