Rock wool sandwich panels are wildly used as a building materials of higher fire protection requirements.Wiskind uses the 98% high-density water-repellent rock wool as the middle material to have the bset performance of sound proof,fire proof,water-resistent,also thermal insulation...

Snap Cap Type Rock Wool Glass Wool Roof Sandwich Panel is bonded and pressed, trimmed, grooved, and blanked to form a tongue-and-groove composite board. Heat insulation, sound insulation, moisture resistance and other characteristics. Its plate's length is not limited, up to 12 meters or more, which fully meets the fire protection requirements of technical design. And it overcomes the defects that the previous sheet does not have sufficient integrity and rigidity, and has poor flexural and impact resistance properties.
