60 thick foam cement board Ⅱ how much noise
Cement foam insulation
Due to the formation of numerous porous bubbles, so the sound-absorbing effect than the average concrete about 5 times higher than the sound insulation coefficient is greater than 45dB.
Product density is light, the volume of dry, the density of about 250kg / cubic, the board through the National Testing Center 1.5 million times the anti-fatigue vibration test, the board and the steel structure as a whole, can reach 9 earthquake.
Foam cement board is A-class non-combustible inorganic insulation materials, have good fire performance, 1200 degrees high temperature baking 3 hours, still maintain integrity, used in buildings, can improve the fire performance of buildings. Because of its closed cell rate of> 95%, which has a good thermal insulation properties.
