New Type Rock Wool/Glass Wool Composite Panel
Polyurethane composite panels are A-grade fire-resistant and extremely robust. Baosin's new fire-resistant rock wool/glass wool sandwich panels are made with two layers of high-quality color steel coated steel plates or other precision-pressed metal sheets as the facings. After rolling forming, the rock wool/glass wool strips are flipped 90 degrees (orienting the fibers perpendicular to the two layers of steel plates). Using a strong, highly adhesive, and fire-resistant adhesive, the rock wool/glass wool is firmly bonded to the metal panels, creating an aesthetically pleasing, flat, and rigid building panel. The formed panels offer excellent fire resistance, thermal insulation, and environmental protection features, providing an excellent choice for industrial building envelope systems.


New Type Fireproof Rock Wool/Glass Wool Board Inspection Report (4-hour耐火时限)
The 150mm and 200mm thick metal facade sandwich panels, as tested by the National Building Materials Test Center, have all passed the fire resistance test with a limit exceeding 240 minutes.

Benefits of Baosin Polyurethane Edge Insulation Board:
Insulation and Heat Retention - Reduces Energy Consumption by 70%
BoXin polyurethane edged mineral wool boards feature a smooth and flat surface, with a precision finish that can be controlled to 0.01cm. The design ensures airtightness and thermal insulation, reducing energy consumption by up to 70%.
2). Noise Absorption and Reduction
Rockwool is an ideal soundproofing material, with its abundance of fine, long fibers forming a porous structure that makes it an excellent sound absorption and noise reduction material, offering sound insulation greater than 30dB, effectively reducing external noise interference.
A1 fire-resistant and flame-retardant
A1-rated thermal and flame-retardant material with a melting point above 1000 degrees. It does not elongate, contract, or deform during fires, effectively blocking the spread of fire and does not release harmful environmental substances or gases.
Waterproof and moisture-proof; water-repellent rate up to 98%
Water-repellent rock wool products with a water-repellency rate exceeding 98%, no pore penetration, and unique interlocking joints between boards prevent water intrusion; the boards do not soften.
