PERFORMANCE DESCRIPTION
The flame resistance level reaches the level A, which has improved the overall fireproof performance of steel buildings. The two edges of the tongue-and-groove is filled with polyurethane foams, which effectively stops heat conduction and rain leakage, prevents reduction of strength and thermal insulation performance caused by moisture absorption and makes fireproof and thermal insulation performance more durable. The high volumetric weight core material guarantees better thermal insulation performance (the volumetric weight of rock wool core materials ≥ 120kg/m3). The two edges of the tongue-and-groove is filled with rigid polyurethane foams to improve the overall strength and prevent deformation of the tongue-and-groove. The fireproof wool rotates 90° so that the wool fiber is perpendicular to the panel and the strength of pressure and tension resistance increases by 50%.
