CENTRIA, a world leader in performance building envelopes, launched in 2017 and now provides as standard its fire retardant Formawall Dimension Series foam-insulated metal panels (IMP) as halogen-free. The panels combine fire safety, high thermal insulation performance, moisture protection and sustainability, come with a Health Product Declaration (HDP, an industry leading standard) and are available with variable thickness, several depths and profiles. The panels are UL-listed for the US and Canada (CAN/ULC-S134) and achieve the future updated NFPA 285 cladding fire test which includes no flame propagation to the next storey up, limits to flame spread above or laterally to window opening and temperature limits throughout the assembly during testing. Testing has also been successfully carried out using 58 different non-CENTRIA materials as weather resistant barriers behind the wall system.
