Dura Flue is the UK’s only stainless steel flexible chimney liner installable in either direction, thanks to its patented process that prevents corrosion and enhances durability. Crafted from two separate stainless steel sheets, it features a tough, wave-profiled outer layer to resist damage during installation and a smooth, oil-sprayed inner layer—free of flaps, folds, or lips—for optimal flue gas flow and corrosion resistance. Unlike traditional liners, which can weaken or splay due to internal folds, Dura Flue’s unique pressure-locked design ensures a pristine, long-lasting performance.
