Rock wool Sandwich Panels are composed of 3 layers, the top and back is two dyed Galvanized or Aluminum corrugated plates, and core materials :high density Rock wool (Basalt vertical filament rock wool). Due to the perfect fire proof performance, rock wool panel are applied as external walls and internal division walls, installed vertically or horizontally on single- or multi-span structure. The panels can be installed horizontally or vertically. The core is made of Basalt vertical filament rock wool, delivered by Rock wool. Thanks to their properties the panels may be applied in object that require very high fire resistance. As the most effective acoustic materials used in construction. Take the 50 mm thick rock wool sandwich panel for example and the panel can absorb the sound over 30 db/m2.Widely used in the steel structure factory building, activities room, roof, wall, air clean room ceiling and partition.
Rock wool core material: the density of 120kg / m3; rock wool block staggered laying, the fiber direction perpendicular to the sandwich is still under the surface, and closely Detailed enrich the entire vertical and horizontal surface movement plate. And wool and, through the high intensity blowing agent connections between the lower plate is formed integrally between rock wool blocks. Sophisticated production process to ensure to produce high density rock wool insulation between the body and the metal plate inside the inner wall of strong adhesion, so that the rock wool sandwich panel has good stiffness.
