The quality of insulation materials has decreased to varying degrees, and the main manifestations of roof insulation materials are as follows:
Firstly, cement tile overhead insulation: low cost, fragile, and even worse than cement board.
Secondly, color steel plate overhead insulation: High cost, can increase a layer of space for storing debris, but it is easy to rust in wind and rain, has a short lifespan, and has a loud noise.
Third, perlite heat insulation: large water absorption and poor heat insulation effect, poor adhesion, easy to crack and empty, and release toxic gas when heated. Some buildings adopt.
Fourth, the bare floor is not insulated: the indoor temperature is higher than the outdoor temperature, and the floor cracks after about 8 years of thermal expansion.
Fifth, cement board overhead insulation: poor insulation effect, heavy weight, increased building load, uneven appearance, and waterproof. Previously widely used, currently no longer used in new buildings.
Sixth, large bubble aluminum insulation blanket: The best insulation effect, with integrated features such as insulation, insulation, waterproofing, anti-corrosion, and environmental protection! Usually used for roofs or ceilings, it can be insulated or insulated at 8 ℃ -12 ℃ after installation. High purity aluminum foil with low radiance and high reflectivity (radiance 3%, aluminum foil purity above 99%) on both sides of the exterior is coated with polyethylene bubble layer with special flame retardant formula (single-layer large bubble, diameter of 30mm), with a total thickness of 8mm. The unique gold surface treatment layer and tensile resistant mesh make it a strong material with anti-corrosion and scratch resistance. Keep your house warm in winter and cool in summer.
