Extruded polystyrene - the phrase on everyone's lips. About him say on television and radio speakers. The entire Internet is hammered advertising banners and slogans. In a word: awful.
During the past year, many of my friends have warmed their homes precisely this material. Most of it has already had time to even get hurt. Despite the threat to life and health of people, not stopping, molded EPS wherever possible.
About the quality of the material, you can learn not only from the pages of the construction sites, but also from Wikipedia. In particular, it is written that a high quality material which can be used in various industries.
That is, from the insulation of walls, foundation and roof, to use in the construction of the roadway and skating rinks. He plays the role of insulation in the refrigeration apparatus, in the construction of sports facilities and cultural centers.
It turns out that this is a fantastic material. It's warm, tight and easy. That is simply irreplaceable.
So what is the problem when you use it?
The sheet is coated with paraffin
Given the high density, combined with the paraffin-coated, then it becomes perfectly clear that the adhesiveness rapidly tends to "zero."
That is, to the surface of the material is bad stick adhesive for facades. When using sheets for these purposes, they must additionally be fixed with dowels. If we strengthen the grid in the thermal insulation adhesive, then the feature of the material plays a fatal role.
Just one year after installation, insulating layer with mesh and special embodiments decorative coating simply fall off.
This happens even if you decide to remove a bit of paraffin with a wire brush. In this case, the material will last for a maximum of 2 months longer.
Here we look at the cost of the material and consider how much we get!
The issue of water vapor permeability
In any home a person needs something to breathe. If not for this feature of our body, then it was possible to cover the walls of ordinary foamed polyethylene. It's cheap, economical, keep warm, do not miss the air. But alas, the breath will be nothing!
Permeability standard polystyrene for facades mark 25 is identical indicators pine boards across the fiber.
The walls are breathing, excess steam and moisture out into the street. The walls remain dry. Everybody is happy.
Here we pay attention to the fact that water vapor permeability of the EPS is 5 times lower than that of the styrofoam!
In this case, it turns out that you are wrapped with a film house. The consequences are predictable.
Designated application EPS
It can be used for thermal insulation of the basement to the ground. In theory it is suitable for the blind area. But - it's not 100 percent fact. If the above ground level, then take further reinforcing mesh which is secured by means of dowels. But the best material to use for the installation of underfloor heating.
Where it is forbidden to use the EPS?
- When the design of facades. With that, it is not suitable even for one that has to be covered with siding.
- Absolutely unacceptable to use for roofing installation. No paropronitsaemlosti.
Do not risk your health and personal savings. Do not use this material wherever you can and want to.
Advertising EPS - divorce!
