FuranFlex Duct Lining Technology Demo 

This video introduces the adaptable FuranFlex and VentilFlex lining system, the ideal solution for duct lining and chimney lining, especially where access is tricky and where maintaining the flue size is important. The liners ship in a soft state and they are tailor-made to fit any chimney or duct size. Air and steam are used to inflate the liner once it's inside the chimney and the heat from the steam will harden the composite material.
