Non- fire rated duct work can be responsible for allowing the initial spread of fire between compartments, and by allowing the rapid spread of smoke throughout a building. The correct design and installation of fire rated duct work will maintain fire compartmentation for air ventilation, kitchen exhaust, and a wide range of other mechanical and electrical services.

Progressive Materials stock Promat’s full range of fire rated duct work systems including PROMATECT® L500, PROMATECT® L, PROMATECT® H and DURASTEEL® boards, as well as PROMASPRAY® P300 vermiculite spray.

Promat’s fire rated board systems are capable of achieving circuit integrity ratings to essential services to enable services such as emergency lighting and ventilation systems to continue operating at a specific temperature under fire conditions.
