Substrate under a laminate from the made foam polyethylene
In order that the laminate in use was not deformed, the basis under its laying has to have ideally plain surface. If the laminated parquet keeps within on a concrete surface or a tile, a working floor needs to be laid waterproof material, laying on any other surface does not demand additional water-proofing. To isolate a floor from unnecessary noise and to smooth all roughnesses, directly under the laminated board place a special substrate. The substrate provides depreciation of a floor when walking, and also its thermal insulation and a sound absorption.
There are several kinds of substrates under a laminate. The most widespread and widely applied substrate is made of a penopolietilen. Thanks to the porous structure and fine properties, this material has good operational characteristics. It is possible to refer low resistance to a sunlight and gradual consolidation to shortcomings of a substrate of this look in use.
