1:The flame resistance level reaches level A, which has improved the overall fireproof performance pf steel buildings,
2:the two edges of the tongue-and-groove are filled with polyurethane foams, which effectively stop heat conduction and rain leakage prevents the reduction of strength and thermal insulation performance caused by moisture absorption and makes fireproof and thermal insulation performance more durable.
3:the high volumetric weight core material guarantees better thermal insulation performance (the volumetric weight of rock wool core material.120kg/m3, the volumetric of glass wool .64kg/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-groove.
4: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.

Compared with other building materials, the PU sandwich panel can effectively prevent cold energy transmission due to the larger temperature difference between the inside and the outside, so cold storages are more energy-saving and the working efficiency of cold rooms is improved.
