ROCK & GLASS WOOL SANDWICH WALL PANEL SYSTEM

Metal curtain wall sandwich panel (rockwool / glasswool)
DUOWEI new model fireproof rockwool/glasswool sandwich panel is recombined into a beautiful, flat, and tough building board by choosing two layers of high-quality color coated steel sheets or other precisely profiled metal sheets as its faceplates, rotating the stripped rockwool/glasswool 90 degrees after roll forming (make the fibers vertical to the upper and lower steel sheets) and strongly binding high-quality rockwool/glasswool with the metal faceplates using high-strength, high-adhesion, high-fire-prevention binder. Excellent fire-prevention, thermal insulation, environment protection and other characteristics of the formed boards provide a best choice for industrial building envelope system.
Advantages of new model rockwool/glasswool
● Non inflammability and Level A fireproof performance
● Hydrophobic property and high ageing resistance
● Excellent performance in thermal insulation
● Sound absorption and noise reduction
● Biodegradable and environment-friendly
● High acidity coefficient can greatly reduce the corrosive action on metals
Disadvantages of conventional mineral wool (slag wool)
● Due to its high dust content and low acidity coefficient, it has a strong corrosive effect on metals.
● Its high hygroscopicity can lead to a sharp decline in thermal insulation performance, thus cold bridge phenomenon is easy to happen.
