1) Sealing performance:Rock wool sandwich panels make use of the excellent waterproof of polyurethane products, overcomes the disadvantage of easy water absorption and deliquescence of rock wool, and effectively prolongs the service life of products in terms of physical properties.

2) Aesthetic performance: round and smooth appearance, flat and beautiful board surface, tight joints and reliable strength.

3) Good stiffness: after the sandwich panel is fixed with the purlin through the connector, the overall stiffness of the roof is greatly improved and the overall working performance of the roof is strengthened. Rock wool sandwich panel can be used with large purlin distance, which can save 1 / 3 ~ 2 / 3 of purlin consumption.

4) Reasonable buckle connection method: theRock wool sandwich panel adopts concealed buckle connection, which avoids the hidden danger of water leakage at the roof panel joint and saves the amount of accessories.

5) Short installation period: the average daily installation area of rock wool sandwich board is 600 ~ 800m2.

6) Scratch protection: during the production of Rock wool sandwich panels, polyethylene self-adhesive protective film can be pasted on the surface to avoid scratch or wear on the surface coating of steel plate during transportation and installation.


Sandwich panels with a mineral wool core are non-flammable.
They can be used in projects which require above-standard fire protection ratings. It is widely used for the ceiling and partition of the roof, wall and air clean room of steel structure workshop and simple movable room.
