Many homes nowadays are warmed by warming. Floor heating brings new performance requirements to the floor. Because there are many kinds of floorboards on the market, many consumers feel very sorry and do not know what kind of floor is more suitable. In fact, pay attention to the three aspects of performance, generally you can choose to fit the warm floor.

First, the dimensional stability is better
This depends on the substrate density and internal bond strength of the floor. The higher the internal bond strength, the better the ability of the floor to withstand temperature changes and the phenomenon of cracking will not occur. Only the floor of the wood material with relatively dense wood can ensure Long time no cracking or deformation under high temperature. Not afraid of the wet environment that is the thickness of water absorption expansion. The floor used for water-heated floor radiant heating requires a small dimensional change in a high-humidity state and an expansion rate of 2.5% or less. In general, the smaller the expansion rate, the better the moisture resistance of the floor.
Second, formaldehyde emission can not exceed the standard
It is required that the amount of formaldehyde released will not exceed the standard in the condition of prolonged heating. When consumers choose geothermal floor, we must choose the floor with low formaldehyde content as possible, because the higher the temperature, the more formaldehyde emission, in the relatively closed residential room, plus the release of formaldehyde caused by other indoor articles, indoor formaldehyde has It may exceed the standard and cause harm to the human body.
Third, heat transfer faster
There are not many brands on the market that can provide heat transfer coefficient. Consumers should pay attention when buying. Products with high general coefficients perform better in terms of heat conduction. Not afraid of high temperature because of the geothermal floor to withstand high temperature heating for a long time, requiring product decorative layer performance is stable, in the long-term high temperature conditions will not fade, rough light phenomenon Composite floor is more suitable for geothermal heating In general, imported flooring quality European Enpr13329 standard, the quality of domestically produced flooring meets the national GB/T1802-2000 standard, and can be adapted to the technical requirements for geothermal heating floor installation.
May look at these general standards, some readers still do not know what kind of product should be selected. There are many types of flooring on the market today, including solid wood flooring and laminate flooring. In general, laminate flooring is more suitable for geothermal flooring. Because the standard thickness of the geothermal floor is 6.5~8.5mm, the thickness of the composite floor is mostly 6-9mm, in which the reinforced laminate flooring is mostly 6~8mm, the three-layer solid wood composite flooring is 8~9mm, and the heat transfer performance is better. The surface has a wear layer of aluminum oxide, which is conducive to the rapid diffusion of heat at the surface.
The thickness of solid wood flooring is generally about 2cm. When installing it, the keel must be used. If it is used as a geothermal floor, there is air between the floor and the ground. The thermal conductivity coefficients of air and wood are very low, so that the heat is not easily transmitted to the surface and can cause heat. The waste is caused by uneven surface temperature and obvious temperature differences.
And the laminate flooring is pressed at high temperature, and the internal moisture content is very small, so the floor will not be deformed due to moisture loss. Each layer of multi-layer solid wood flooring is intertwined horizontally and horizontally, restraining each other, and there is also a dense anti-deformation groove on the back surface, which decomposes the stress generated on the heated surface, so the deformation is very small. The solid wood floor has a high moisture content and is easily cracked and deformed when heated at a high temperature for a long time.
If you must use ordinary solid wood flooring, you should try to use the back of the film layer floor, because it can prevent moisture and moisture, and can maintain the wood moisture content and the ambient humidity balance.
The design of the locking floor is more conducive to heat transfer. It is worth mentioning that in the composite floor, the effect of the lock-type floor is better than that of other products. Because there are small gaps between the hooks and the floor, the floor is exposed to heat and moisture. It is not easy to go out after expansion.
