In fact, there is no best thickness for laminate flooring, because each thickness of laminate flooring is applied in a different place. Now, the sizes and specifications of the reinforced floor sold on the market are relatively long and wide. In fact, this is not very good, because the floor is more suitable for short rather than long, and should be narrow rather than wide, so choose the best floor less than 600 mm * 75 mm * 18 mm floor, because the smaller the floor size, its anti-deformation capacity is stronger, the general floor thickness in 18 ± 0.2 mm is just right, too thin easy to break, service life is not long; too thick, not only affect the height of the indoor floor but also affect the heating. Whether it's the best thickness for laminate flooring or not, it should be up to the national standard for flooring quality, because there will be substandard flooring whether it's thick or thin, qualified floor to achieve the basic thickness of the size, quality indicators, density and internal bonding strength, water absorption thickness, formaldehyde emission of these indicators.
