All the "pros" and "cons" of polystyrene blocks
Polistirolnye units sold in the market of construction materials is already 15-20 years, but still many people choose the building material, not really appreciating its negative side. I hope this article will put an end to errors at least the small part of the builders, who will read this article.
So, what is the polistirolbloki?
These blocks are made of cement mortar adding synthetic - polystyrene block which reduces weight and increases its insulating capabilities. For those who have not seen the polystyrene blocks are as follows:
Strengths of polystyrene:
- High load capacity (Two or more stages can construct);
- polystyrene - warm material;
- fireproof material;
- polistirolbloki do not shrink.
disadvantages of polystyrene
Unfortunately, the number of freeze / thaw cycles polystyrene is limited - 100 times. That is, the walls of your houses of this material retain their load-bearing capacity only for 100 years. Grandchildren will likely have to rebuild the house.
If polystyrene is wet before I was laid and plastered, inside cracks and defects. The only salvation - insulation and plastering, which increases the cost of the material.
Output:
Build from polystyrene or not - you decide.
But I recommend to pay attention to other material - aerated concrete, Devoid of the drawbacks of polystyrene.
