bond strength, internal bond strength is more high, that ability is better the floor under the temperature change, not cracking phenomenon, only relatively compact substrates for the wood floor, in order to ensure the long-term high temperature cracking, no deformation. Not afraid of wet environment, that is, water absorption, thickness expansion rate. The floor used for water heating ground radiation heating requires a small change in the high humidity condition,

and the expansion rate is less than or equal to 2.5%. Generally speaking, the smaller the expansion rate, the better the moisture resistance of the floor. Two, formaldehyde emission requirements in a long time heating conditions, formaldehyde emissions will not exceed the standard. Consumers choose to heat the floor, must as far as possible to choose the low formaldehyde content of the floor, because the higher the temperature, the more formaldehyde

emissions in a relatively closed room, plus other items caused by indoor formaldehyde release, indoor formaldehyde may exceed the standard, cause the harm to human body. Three, the heat transfer market can provide heating conductivity of the brand is not much, consumers should pay attention when buying. Generally high coefficient products in thermal conductivity, better performance, not afraid of high temperature. As the geothermal floor to withstand
