Density basis significantly influences the characteristics of laminate. The higher the density, the higher, respectively, and the mechanical strength of laminated boards (in particular the fracture strength, impact resistance, resistance to pressure and prolonged stress), and higher humidity. But at the same time with increasing density of deteriorating fundamentals strength adhesive bonds (adhesion) laminate boards for installation of floor covering. Base thickness – from 6.2 to 10 mm. 4.

The stabilizing layer (thickness of 0.1 to 0.8 mm) is impregnated with melamine resin or wax paper. The bottom layer prevents the penetration of moisture into the plate and stabilizes the cover, fitting its climate change in the room. 5. As an additional layer can be applied to reinforcing coating (multiple layers of kraft paper), which is introduced between the decorative layer and base layer as a reinforcement in to increase the hardness of the surface layer of foundation and thereby increasing the shockproof laminate flooring. This layer also provides additional rigidity edges of laminated board. 6.

The structure laminated panels may also include absorbent layer attached to the back of the panel. Classes durability laminate flooring laminate quality is determined by the class durability. To assess the quality of this material is the European association of manufacturers of laminate flooring (EPLF), which consists of 19 producing countries, adopted in 1999, the European standards for laminate flooring. Each type of floor is being tested on 18 different tests such as abrasion, impact resistance, sound insulation, resistance to scratching, to the light, etc. The test results laminate assigned a class that defines the conditions for its operation. In total there are six teams, but today manufacturers primarily produce laminates of three classes – 31, 32, 33 classes, which are used both at home and in commercial terms. It should be noted that at present day of the distinction between purely domestic and purely commercial laminate heavily blurred.
