The Fire insulation board is made of polystyrene resin as raw material plus other raw and auxiliary materials and polymers, and the catalyst is injected through heating and mixing. The rigid foam boards produced by extrusion molding are then extruded. Next, let's take a look at the construction proc

Insulation board has performance characteristics such as high fire resistance, high heat preservation, relatively good strength, not easy to break, lightweight, non-toxic and harmless, long life, good water resistance, good interface, energy saving, and safety. However, the construction of the Roof

Insulation decorative plate is easy to understand, it is a board for building insulation. It has moisture-proof and waterproof properties, which can reduce the thickness of the building's outer envelope, thereby increasing the indoor usable area. Next, let's take a look at the two common types of In
