Substrate density and internal bonding strength - the higher the internal bonding strength, the better the ability of the floor to withstand the change of geothermal temperature, and the phenomenon of cracking will not occur. According to the characteristics and requirements of geothermal, the base material of geothermal floor adopts relatively dense wood In order to ensure that it will not crack or deform under high temperature for a long time; the expansion rate of water absorption thickness - should be less than or equal to 2.5%, the smaller the expansion rate of water absorption thickness, the better the moisture resistance of the floor; , Because the higher the temperature, the more formaldehyde will be released. In a relatively closed living room plus the release of other items (such as large core boards, etc.), the indoor formaldehyde may exceed the standard and cause harm to the human body. Thermal conductivity - Few brands on the market offer thermal conductivity, and consumers should pay attention when purchasing.
