In the process of repairing a private house, there is often a question of selecting the most optimal material with the best thermal insulation properties at the lowest price.
In the event that this question has risen in front of you, it is worth considering the use of foam as a heater, which is also called expanded polystyrene. This material is optimal when it is necessary to create an effective barrier for heat loss and for propagation of noise. The high rating of this material among other heat insulators is due to its high performance and compliance with environmental requirements.
Properties of foam
Polyfoam is a foam polymer with a number of advantages compared to other thermal insulation materials. Its sheets, having extraordinary lightness, can be successfully used in any kind of work related to the arrangement of internal and external thermal insulation.
As an example, we can cite a fairly common fact of the insulation of balconies of city apartments with the help of this material. It will also create an incomparable thermal comfort in the event that the foam is laid out the floor of the attic in a private house or used to insulate the attic. We do not even mention the thermal insulation of the walls of the houses, as this is a very obvious and broad sphere of the use of this polymer.
Thermal insulating properties of foam are widely known, but what are the other advantages of this thermal insulation material?
- Polyfoam is not subject to aging, does not break down over time.
- The properties of the foam do not change under any environmental influences.
- Polyfoam is not a rotting material unlike natural organic substances.
- This polymer perfectly combines with almost any building materials.
Being initially combustible, the foam becomes refractory, due to the presence of appropriate additives in it.
At the same time, the foam plastic retains all its advantages only if the following conditions are met:
- no direct sunlight;
- no temperature exceeding + 95 ° C;
- no contact with some solvents.
It is quite obvious that the economic feasibility of using this material as a heater, due to its high cost and excellent performance.
Foam grades and their use
This material is produced in sheets of the following sizes( in mm):
- 500 × 1000
- 1000 × 1000
- 1000 × 2000
Different grades of foam are used in different types of insulation:
- 10, 15, 20 - as an averagelayer of three-layer insulation;
- 25, 35 - for the manufacture of thermal insulation of floors, roofs and similar structures;
- 35N - in the case of insulation of such surfaces that experience a rather high load.
