Foil insulation is one of the innovative insulation materials that found quite widely used in the field of thermal insulation of both industrial premises and residential.
The peculiarity of the structure of such insulation is that it consists of two layers: the first is the basis of basalt wool or foamed polyethylene, the second is the so -called reflective layer, for which aluminum foil or a special metal film is used. It is produced in two forms: foil heater and sheet.
In the manufacture of this type of heater, foil is applied in a special way by welding and polished to high reflective ability. For a room where the humidity level is very high, a heater with a metallized film is more suitable.
Such thermal insulation is used not only for premises, but also for thermal insulation of communication channels: pipelines, ducts.
The main operational characteristics
It is worth noting that the basalt and polyethylene insulation foam differs in their properties, which determines their different areas of use.
Ground polyethylene insulation based on foamed polyethylene is characterized by excellent vapor barrier, thermal insulation and soundproofing properties, which allows us to widely use it for wet rooms. So, if you need a foil insulation for a bath and sauna, this is a great option. Another factor indicating in favor of choosing this type of insulation is its price.
Professionals believe that given the quality of polyethylene foil insulation, its versatility is the best choice for repair. It is only necessary to consider that the price can differ significantly depending on the thickness and configuration of the material you need.
Let’s see what is so good insulation based on foamed polyethylene?
Excellent thermal insulation helps the insulation, both to maintain heat and prevent radiation and ensure thermal insulation. That is why it is the most popular insulation foil for the bath.
Using this type of insulation allows you to isolate the room from the wind, noise, exposure to water and steam. In this case, the insulation does not deteriorate under the influence of moisture and other influences. Not subject to decay and decay, protecting the room from all harmful effects.
The next positive property is highlighted by the strength of the foil insulation. This is due to the properties of the materials that make up the insulation. This is partly due to the fact that it is quite dense, the minimum thickness of the foil insulation starts with 10 mm. But in the case when you need to save a place, there are no special compartments for the insulation and you need insulation that does not take up a lot of space, you can choose the minimum layer thickness. In addition, the thickness of the material allows you to roll the insulation into rolls and thus increase the convenience of its transportation.
One cannot fail to mention such a quality as high environmental friendliness. Foil heater does not have harmful discharge, it does not cause allergic manifestations that can often occur in contact with insulation when you put them with your own hands. High degree of insulation safety allows you to widely use it for residential premises.
There is another property that makes this type of insulation almost unique. We are talking about his ability to reflect radiation radiation. This becomes possible thanks to the upper coating made of aluminum with a high (up to 97%) coefficient of light reflection. Therefore, we recommend using foil insulation for walls of production facilities, where there is a need to reduce the effects of radiation.
We note such an important quality as ease of installation. Almost anyone can cope with it, no special equipment or high level of professionalism needs to lay insulation. Flaged self -adhesive insulation is especially convenient in installation, since it does not require any special additional method of fastening. On the features of foil insulation, see the video in this article.
The basalt foil insulation has a fairly specific sphere of application due to its characteristics. Since it is distinguished by fiery resistance, resistance to the effects of chemical and biological substances, greater strength, it is most widely used in those places where special protection against heat loss, especially due to temperature and weather influences, is needed.
As we have already said, foil insulation is widely used in many cases, in particular, for thermal insulation of floors, pipelines, or, conversely, as a heat reflector next to heating batteries. It will also be useful for protection against noise, humidity and heat conservation when laying into the walls, roof. Another scope is heat – and waterproofing of baths, saunas.
If the foil of the foil is applied on both sides, it can be used to warm the roof. At the same time, he will not only maintain heat, but, on the contrary, in the case of heat to keep cool in the house (according to the principle of thermos).
Heater laying instructions
When laying the insulation, it is worth knowing several simple rules. So, you will feel a much greater effect from the material. If it will not be laid close to decorative decoration, but leaving an empty space about 2.5 cm.
Before installing the insulation, you need to clean the wall of dirt and dust. We also recommend treating the walls with an antiseptic composition, especially this is true for wet rooms. It is recommended to make a special crate for uniform distribution and more convenient mounting of the insulation. You need to lay the insulation with a foil layer inside the room (look at the photo). After completing work on laying insulation for better maintenance of heat, you should definitely glue all the joints between the sheets of insulation with special tape based on foil -based.
As you can see, this type of insulation is quite universal, differing at the same time excellent operational properties and ease of installation.
