Ductwork Cladding with Silicate Board is a key material for fire safety in building smoke control systems. In fires, smoke is the primary lethal factor and a major pathway for fire spread. According to national standards, smoke control ducts need to have a fire resistance rating of 0.5h to 3h. Our developed FCA fireproof board is specifically designed for smoke control ducts, providing reliable protection for building safety.
