Insulated laminate underlays/parquet underlays San Decor

The top layer of polyethylene is in contact with the finishing floor covering - laminate. It is very tight, this design allows it to be an excellent protection against moist environment. Plus, in the process of laying on a cement screed or concrete floor it is not necessary to open an additional layer of polyethylene film.
The bottom layer is marked with a logo. It is placed over the rough floor. It is made of a special polyethylene film with numerous microscopic holes. When moisture enters the inside of the surface, it penetrates between these foamed granules, which are not exposed to moisture. In this case, due to ventilation, moisture exits from the end parts of the material, which is always located near the walls of the room. Yes, it does not harm the floor covering and simply goes into the atmosphere of the room itself.
