1. Polyurethane rigid foam Polyurethane rigid foam is a kind of low-density microcellular foam material with closed cell structure, which has low thermal conductivity, good thermal insulation performance, low water absorption and convenient use.
In China, the application of rigid polyurethane foam on roofs is still in the initial stage, mainly through direct spraying.
Generally, it is sprayed and foamed on site, which can be used on the roof of any complex structure.
Second, polystyrene board insulation layer polystyrene board is a roof board made of cement and broken polystyrene foam.
The polystyrene board is located between the fine stone concrete surface layer and the waterproof layer, which not only has the function of thermal insulation, but also has the function of isolation layer to prevent the waterproof layer from cracking when the fine stone concrete surface layer expands with heat and contracts with cold.
3.FS cement and fly ash thermal insulation roofing FS thermal insulation material is made of fly ash, sulphoaluminate cement, foam stabilizer and foaming agent by casting and foaming at normal temperature and pressure.
Its environmental protection and comprehensive utilization are good.
FS thermal insulation material has good thermal insulation performance because of its low density and low thermal conductivity.
Fourth, FB new composite roof panel FB new composite roof panel integrates many functions such as light weight, heat preservation, heat insulation and waterproof.
Its overall dimensions are1200mm× 700mm×100mm. The wet process of roof insulation, waterproofing and leveling is changed into factory production, which improves the efficiency, and the construction speed of roof engineering can be increased by 2-3 times, which is about 230kg/m2 less than that of traditional roof.
