<P>Ground warm is passed through the ground heat source to the surface, through the radiation process to the air heating. State ground radiation heating technical regulations JGJ1402-2004 3.1.2 requirements of the ground design temperature of 24-28 ℃. Thickness of 12 ~ 16mm of the floor is the most suitable to use,quick caps composite deck reviews such as the design of special needs can only increase the warm water temperature, which will reduce the service life of the warm system. Too thick on the surface of the upper and lower surface temperature difference is too large expansion is not consistent,plans to make a bench seatfor decks long-term use will make the floor deformation.</P>
<P>Formaldehyde is a variety of gel and paint the cheapest dilution blowing dry economy, the current chemical technology has been able to produce formaldehyde-free products, but the price is higher. National floor standards require formal floor formaldehyde content E1 level <= 1.5mg / L. But the higher the temperature,wood plastic composite fences the greater the amount of formaldehyde release.</P>
<P>So to warm the floor should be no formaldehyde to ensure the health of consumers. But nothing is impossible. Because in the natural logs also contain a small amount of formaldehyde,wear resistance synthetic decks but their content is very small, will not cause harm to the human body.</P>
