In addition to chemical inertness and mechanical strength, Harvel CPVC Duct also has excellent flammability properties when compared to many common building products. Harvel CPVC Duct will not independently support combustion. Harvel CPVC Duct will not burn unless a flame is constantly applied and stops burning once the flame is removed. In addition to burn resistance, Harvel CPVC Duct has exceptionally low flame-spread and smoke-generation properties, and is listed by Underwriters Laboratories of Canada for surface burning characteristics. |
