125mm (5 inch)

Our 125mm flexible flue liners are designed for re-lining an existing chimney that has failed or to increase the performance of the chimney. The 125mm flue liner can only be installed in a masonry chimney and it has to be completely enclosed within it. A wood and plasterboard or similar materials are not acceptable.

We supply 125mm flue liners in two different grades, 316L and 904L. The latter is a higher grade that is suitable for the more extreme conditions that are found with coal-based solid fuel installations. A multi-fuel flexible flue liner comes with a manufacturer’s lifetime* warranty.

We also supply a selection of flue adaptors, tops plates, rain caps, and register plates. If you’re looking for a 125mm flue liner, then take a look at our range below. We are leading providers of flue supplies in Birmingham, Wolverhampton, and the West Midlands.

*"Lifetime" refers to the lifetime of your appliance.
