DUOWEI new model fireproof rock wool/glass wool sandwich panel is a choice of two layers of high-quality color-coated steel plates or other precision-profiled metals. The plate is used as a panel, and after roll forming, the slitting rock wool/glass wool is turned 90 degrees (so that its fibers are perpendicular to the upper and lower layers of steel), bonded by high-strength, high-adhesion, and high-fire-resistant adhesives, with the high-quality rock wool/glass wool, to composite into aesthetic, flat, robust building panel. The composited panel has the features of excellent fire resistance, thermal insulation and environmental protection. It provides an excellent choice for industrial building envelope systems.
