Solid Fuel Flexible Liner

Our flexible flue liner is the top performing chimney liner with a 10 year guarantee.

Deeply corrugated BS 1449 316 grade stainless steel is manufactured into a twin wall flue liner
which combines great strength with flexibility. Thickness 0.105mm.
A superior 904 grade liner is also available offering a 20 year guarantee, please call for details.

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 unimpared flow of flue gasses.

Inner and outer layers are joined by a 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.

»Specification
The twin wall construction, with triple lock and overlapping joints, enables the liner to withstand operational temperatures of up to 750° C and short fire temperatures of up to 1000° C - e.g., a chimney fire (In the event of such an occurence, the future liner performance will be adversely affected)

Suitable for all standard fuel oil and gas installations, coal, coke, cured dry logs and cured dry peat
