Dundas Jafine’s Flexible Insulated Duct is UL / cUL 181 listed as a class 1 air duct and bears the UL mark. This duct consists of a flexible helix core made of 2 ply polyester laminate and corrosion resistant galvanized wire. It is surrounded by a blanket of formaldehyde free, fiberglass insulation, that helps to reduce heat and cool loss as well as jacketed by a heavy duty, fire retardant, silver polyethylene vapor barrier with reinforced scrim.

Flexible insulated duct can be installed in place of galvanized pipe in most applications. In addition, due to its flexible nature, the need for elbows is eliminated, allowing for ease of installation in difficult to reach areas. This duct is ideal for use in general ventilation applications.
