Grate EPS insulation board
Grate polystyrene board is commonly known as "black foam" or "blackboard", referred to as SEPS, its full name for the B1-level grate molded polystyrene foam board, widely used in building, wall insulation system, especially is used in the exterior insulation project which the polystyrene board need reach B1-level fire safety requirements
1, grate polystyrene board with good fire performance, combustion performance can reach B1 level flame retardant;
2, Insulation capacity is stronger, it is a classic insulation material foamed polystyrene further refined by chemical products, thermal conductivity ⤠0.032, its thermal insulation capacity is 30% higher than ordinary EPS, can improve energy efficiency and reduce carbon dioxide emission.
3, the same effect of lower cost, cost-effective grate polystyrene board, with outstanding thermal insulation ability, especially in the low density, it can be clearly demonstrated, in the case of the same effect, than other fire-resistant insulation system can save more cost.
4, Simple construction, good system integrity, grate polystyrene board insulation system construction and EPS thin plastering exterior insulation system construction methods are consistent, higher system integrity and durability.
