Product Details

PU sealing Rock wool sandwich roof panel are constructed with non-combustible structural rock wool as the core material, clad with galvanized or aluminum-zinc coated steel sheets, and sealed at both ends with polyurethane. Through advanced adhesive technology, these components form a high-quality, energy-efficient building panel. The double-sided polyurethane sealing of the rock wool sandwich panel maximizes the inherent properties of the rock wool core, providing excellent fire resistance, thermal insulation, and sound absorption. Additionally, it retains the advantages of polyurethane, including its plasticity, airtight, high strength, and water resistance. This integration results in a panel that combines fire protection, thermal insulation, noise reduction, and aesthetic decoration.

Product feature

(1) Sealing performance: PU sealing Rock wool sandwich roof panel adopts the assembly line production process, which takes advantage of the excellent water resistance of polyurethane products to overcome the shortcomings of rock wool easy water absorption and dehydrating, and effectively extends the service life of the product in terms of physical properties.

(2) Good stiffness: The core material of the product and two layers of steel plate bonded into a whole, working together, coupled with the roof plate surface wave pressure type, the overall stiffness is far better than the pressure type plate rock wool (glass fiber wool) field composite plate. After the sandwich plate is fixed by connecting pieces and purlins, the overall stiffness of the roof is greatly improved and the overall working performance of the roof is strengthened. The selection of rock wool sandwich board can use a larger purlin distance, so it can save 1/3 ~ 2/3 of the purlin consumption.

(3) Reasonable fastening method: This roof panel adopts a hidden buckle connection mode, avoiding the hidden danger of roof plate joint leakage and saving the amount of accessories.

(4) The fixing method is firm and reasonable: PU sealing Rock wool sandwich roof panel is fixed with special M6 self-tapping screws and purlins, which can effectively resist external forces such as typhoons. Self-tapping screws are arranged at the crest position between the joints of the two panels of the roof panel, and special waterproof construction is adopted to avoid waterproofing weak points.
