XPS Insulation board has a dense surface layer and a closed-cell inner layer. Its thermal conductivity is much lower than that of EPS with the same thickness, so it has better thermal insulation performance than EPS. For the same building's exterior wall, its thickness can be less than other types o

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
