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.

stability by distributing forces evenly round ther flue liner.
