Laminate is one of the most popular floor coverings. There are good reasons for it: it is nice, practical and durable. To avoid unpleasant surprises after the flooring works, it is necessary to use a special underlay below the laminate flooring. The laminate flooring underlay is an intermediate layer between the concrete subflooring and laminate. The laminate flooring underlay performs several functions: at first, it provides a perfect flatness of the surface. Second, it creates cushioning and sound insulation, which is especially important for residents of multi-apartment houses: the neighbors below will not complain about the loud noise from the corridor. Third, together with the polyethylene layer, the underlay protects laminate from moisture, which could be contained in the concrete subflooring.
There are several types of laminate flooring underlay. In the course of flooring works in premises, the pressed cork underlay is often used as underfloor for the laminate flooring. This material is produced from the bark of the cork oak; it is harmless and has excellent thermal and sound insulating properties. It remains unaffected by rotting and mold formation.
Extruded polystyrene is a unique and seemingly the most up-to-date material for the laminate flooring underlay. Due to the special design, it is very light but at the same time durable: if installed correctly it will serve more than 50 years. The important characteristics of extruded polystyrene are environmental friendliness, moisture and chemical resistance.
Laminate flooring underlays made of fir tree appeared on the market of finishing materials recently, and have already become popular among buyers. Due to the thickness of 4 mm, these substrates for laminate are especially strong: they provide the flooring with reliable protection against deformation and ensure excellent sound insulation. In addition, fir tree laminate flooring underlays are harmless to people health: it could be used even in homes with small children or people with allergies.
