Chimney Flue Liners for Open Fires, Gas Fires & Stoves

We install chimney flue liners for all types of masonry chimney stacks. 

Stainless Steel Liners are there for your safety and also to help the performance of various appliances, notably wood burning or multi fuel stoves. In our experience we have found that stove with liners perform better and are easier to control through the air vents.

Our flue liners are constructed with deeply corrugated BS 1449 316 grade stainless steel and is manufactured into a twin wall flue liner which combines great strength with flexibility. Outer corrugated layer provides a protective casing during the installation process and after installation it helps protect the inner layer from corrosion due to attack by residual deposits. The inner layer is smooth to discourage the build up of soot and other potentially corrosive residues and to encourage the unimpaired flow of flue gasses.

Inner and outer layers are joined by the Triple Lock Joint System. Acknowledged to be the best jointing system available, the Triple Lock Joint provides strength and stability by distributing forces evenly round the flue liner. The overlapping joint construction protects the joint from the potentially damaging effects of condensation.

The twin wall construction, with triple lock and overlapping joints, enables our liners to withstand operational temperatures of up to 750° C and short fire temperatures of up to 1000° C - e.g., a chimney fire.
