A twin skin multi fuel flexible chimney liner used for relining masonry chimney stacks.

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 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 ther chimney 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 this chimney 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)

Our chimney liner is manufactured using two separate strips of stainless steel, making it stronger and more flexible than others. It also will not split when installing.
