1, thermal insulation gauze
At present, the thermal insulation material used in the market is thermal insulation gauze. The heat insulation net is made of nylon. After chemical treatment, the sunlight is reflected, so as to reduce the direct long-term exposure of sunlight to the roof and achieve the purpose of reducing heat. The use effect is still very good.
2. Extruded polystyrene board (XPS board)
Extruded polystyrene board has relatively good thermal insulation performance, moisture resistance and higher price than other thermal insulation materials, and its thermal conductivity is about 0.028-0.03.
3, asbestos board
The thermal insulation effect of asbestos board is obvious to all. The insulation principle of insulation board is mainly influenced by the gas in the pores, which determines the insulation effect of insulation board.
4, fire board
Fire insulation board can not only be waterproof, but also play a role in fire prevention. Roof insulation board is the first patented product in China, which is made of perlite, a small amount of mineralized raw materials, plant fibers and other natural materials. Made of scientific thermal reaction and special processing technology. It has a series of advantages such as heat preservation, waterproof, fire prevention and heat insulation.
