Flue Liner

Quattro-Plus is our flexible flue liner which is designed for re-lining an existing masonry chimney that has failed or to increase the performance of the chimney. This chimney flue liner can only be installed in a masonry chimney and has to be totally enclosed within it. A wood and plaster board, or similar, is not acceptable. 

The Quattro-Plus chimney flue liner is manufactured with two skins of either stainless steel and is suitable for gas, oil, and multi-fuel, including wood burning appliances where the maximum flue gas temperature does not exceed 600°C. 

These flexible flue liners are available in two grades, 316L and 904L; 904L, is a higher grade that is suitable for more extreme conditions found with coal-based solid fuel installations. 

Every multi-fuel flexible flue liner comes with a manufacturer’s lifetime* warranty.
