Multi Fuel Liner

Our 125mm flexible multi-flue liners are created for the purpose of re-lining a current chimney that has failed or to increase the performance of the chimney. The 125mm multi-flue liner is only suitable to a masonry chimney and it can only be installed if it is enclosed within it. Materials like wood or plastic will not be acceptable. 

We supply 125mm multi-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 variety of flue adaptors, tops plates, rain caps, and register plates. If you’re looking for a 125mm multi-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.
