Combines the advantages of rockwool and polyurethane. At the same time, it has the non-flammability of rock wool material and the high-quality thermal insulation performance of polyurethane material. The unique polyurethane edge enhances the tightness of the plate, waterproof, moisture-proof, sand-proof and durable.

The rock wool core material and steel plate are formed by roller forming and high pressure composite bonding to form a stable, lightweight and energy-saving new building material. With fire, moisture, heat insulation, heat preservation and other building performance, and a variety of choices, beautiful atmosphere.
