Xuanming Curtain Wall Fireproof Rock Wool Board is designed specifically for various curtain wall systems, with different time effective fire resistance, providing protection for curtain wall fire insulation.
Commonly known as fireproof black cotton, it is not only used for fireproof and smoke sealing of gaps between curtain walls and floor slabs or curtain walls and partition walls, but also for fireproof sealing of other building gaps, including gaps around various pipes that pass through walls or floors, fireproof door partitions, etc. In order to enhance the smoke barrier ability of the product, fireproof aluminum foil is usually covered on the upper and lower surfaces of the rock wool.
