<P>To be used to warm the floor, to meet the E0 level standard, that is, the average formaldehyde emission is less than 1.5mg / l. As for the floor temperature rise is to speed up the suspicion of the release of formaldehyde, it has been done related experiments to warm the use of water coil,outdoor decking no maintenance the water temperature should be in accordance with national standards should be 55 degrees, and through the water pipe to the filling layer, the temperature and then to Wood floor, mostly less than 30 degrees, and this temperature is the wood floor structure will not change, from the Geiger Geothermal floor laboratory structure, the formaldehyde content did not increase significantly. From the experience of the people point of view, a lot of summer indoor temperature is more than 30 degrees. So whether formaldehyde is not directly related to geothermal.</P>
<P>The thickness of the wood floor is to determine whether the foot feel is comfortable, so many consumers in the purchase of flooring, especially the purchase of solid wood, multi-layer solid wood flooring or bamboo flooring are required in the thickness of 15-18mm. To warm the floor,Wooden Door Manufacturing Process they also use this method to pick, can not know the wood is bad conductor, usually wood material thermal conductivity between 0.17-0.34, and water is 0.5. If the floor thickness is too thick, it is more conducive to heat through Floor conduction to the board up, and are consumed in the conduction process. As for the insulation, the floor temperature difference between the upper and lower,the cost of wood plastic composite factory is bound to lead to a large deformation of the floor, "thermal expansion and contraction" "wet expansion and contraction" will cause floor scoop, twist, bend, crack, dimensional stability is not guaranteed (geothermal floor Suitable thickness of 8-12mm).</P>
<P>First of all, geothermal heating below the floor laying plywood or blockboard, is not conducive to heat conduction, virtually heat in the conduction process and increase wear and tear, an increase of geothermal heating system heating costs. Second, if the quality of these plates,exterior outdoor floor tiles but also off, but also lead to indoor free formaldehyde content exceeded, or because of its moisture content is not compliance, after the laying of moisture absorbed by the floor, resulting in floor tile changes, arch and other phenomena, combined This substrate is more harmless, it can be described as self-defeating, superfluous!</P>
