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 heat insulation of attics, roofs or walls. It is also used for noise and heat insulation of engineering communications - air ducts, pipelines. You can simply fasten a heat insulator sheet behind a heating device in order to increase the amount of heat energy supplied. He proved himself excellently in the isolation of rooms with high humidity - saunas and baths. Good for insulating front doors to prevent unnecessary heat loss.
Features
This thermal insulation 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, highly effective thermal insulation of enclosing structures was provided.
With helpthermal welding, a thin layer of aluminum is applied and polished. Thus, foil insulation is able to reflect thermal energy into the room with an efficiency of about 97%. One layer of such insulation, in terms of heat transfer resistance, can replace brickwork 15 cm thick.
Due to its 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 foil insulation has excellent soundproofing properties, and most importantly, it is considered an environmentally friendly heat insulator.
Varieties of insulation
Foil heat insulator does not emit toxic and hazardous substances compared to ordinary mineral wool.
There are several main types of this insulation, they differ not only in appearance, but also in functional features, as well as in the field of application.
- Aluminum-coated polyethylene foam - used as thermal insulation for walls and ventilation systems.
- Foil Styrofoam - is a thick layer of steel color. Used for floor insulation.
- Mineral wool with a layer of foil - sold in rolls. This foil insulation is perfect for a bath, as well as for insulating chimney pipes and roofs.
- Bas alt foil heat insulator - characterized by high resistance to aggressive environments. Hewithstands temperatures from -200°C to +700°C. Insulation is used in all areas of construction, including the construction of gas stations.
Applications
This material is perfect for thermal insulation of the floor, attic and baths. This wall insulation is ideal, the foil layer will provide good heat, noise and waterproofing. Many people use it to increase the amount of heat output by placing a heat insulator behind the heating devices with the "aluminum" side into the room. Thus, for little money, you will protect your home as much as possible from excessive heat loss, frost and wind.
General Features
It is a two-layer foil insulation, which consists of a thermal protective element and an aluminum coating. The aluminum plating is heat sealed and then polished.
General characteristics of various types of foil insulation:
- They don't absorb moisture.
- Heat insulator is resistant to a wide range of temperature changes.
- The material is reflective.
- Insulation is easy to install.
- Penofol foil insulation has excellent hydro, steam and thermal insulation properties.
Benefits
- Foil due to its high reflectivity (within 97%) is a good thermal insulator.
- Due to its flexibility, this heat insulator can be used to insulate building envelopes with a non-standard configuration.
- This wall insulation is perfect, the foil layer will protect them from solar and radon radiation.
- Good water repellency prevents freezing and condensation. This quality protects metal frames from rust.
- This material has excellent sound insulation performance, it does not require additional chemical treatment, and most importantly, it is environmentally friendly.
Foil insulation reviews
Despite the fact that foil insulation is a relatively new thermal insulation material, consumers have already appreciated it. This type of insulation allows high-quality insulation of building envelopes, which can significantly save on heating in winter, as well as insulate engineering communications such as air ducts and pipelines.
According to consumers, this insulation is characterized by the only, but quite a big drawback - the foil layer is subject to corrosion. Moreover, the insulation with a metallized coating does not have such a drawback, so it can be used in the construction of baths and saunas.
Mounting Features
The following materials are required for installation:
- Foil insulation.
- Construction stapler.
- Foil tape.
- Nails smallsize.
- Hammer.
When insulating with foil insulation, you must consider:
- 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 mounted on walls, the insulation must be laid in the crate between the rails.
- After installation, visible joints should remain. They should be treated with foil tape.
- Installation done.
This thermal insulation material will protect the walls of your house from condensation, which destroys the building and contributes to the release of heat from the room.
Now insulation is available to absolutely everyone. You will be able to independently 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, economical option for how to make your own home 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 the cost of heating.
Value for money
The cost of foil insulation is somewhat higher than usual, in this regard, the price is one of the main selection criteria. However, don't get carried awaysavings, forgetting about the quality of the heat-insulating material.
In the construction market you can see incredibly cheap foil insulation under the wallpaper. Before you buy it, you should think: how did the manufacturer manage to produce such a cheap material? In this case, the answer is simple: instead of a real foil, an aluminum coating was applied to the insulation. The material shines just like the real thing, 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 capable of retaining thermal radiation. As a result, you will pay more than for conventional insulation, but you will not win at all in quality. The result is an unjustified overpayment.
