Application
Zhongrunda Curtain Wall Rock Wool Board Curtain wall fireproof and thermal insulation rock wool board is specially designed for various curtain wall systems. It is a fireproof and thermal insulation product with the characteristics of higher fire resistance temperature, higher melting point, longer fire resistance and smaller high temperature linear shrinkage. . It is used for fire prevention and smoke barrier of the gap between curtain wall and floor or curtain wall and partition wall, and it can also be used for fireproof sealing of other building gaps, including gaps around pipes that pass through walls or floors. In order to enhance the smoke barrier ability, fireproof aluminum foil is generally pasted on the upper and lower surfaces of rock wool. It is mainly used for the fire separation of the window sill wall in the curtain wall system. Its superior thermal insulation performance can effectively reduce the heat transfer of this part. The surface can be pasted with decorative materials such as aluminum foil.
