How to choose thermal insulation materials and matters needing attention

1. Choose insulation materials to pay attention to the fire-proof grade of insulation materials, from low to high is divided into flammable, flammable, non-flammable, non-flammable four grades, in the choice of the best choice of fire-proof grade higher. < br > 2. Attention should be paid to the insulation property of insulation materials, which is an important factor to determine the quality of insulation materials. This is mainly through watching the thermal conductivity of insulation materials, so more attention should be paid.
