Reasons to line a chimney Fitting a flue liner Insulating a flexible liner

A flue liner kit 316 Grade or 904 Grade?

If you are just burning seasoned wood then you should buy the 316-grade flue liner kit. If you are burning a mix of seasoned wood and smokeless coal, or smokeless coal on its own, then the 904 flue liner kit will be a better choice.

Quality chimney liner kit

Lining a chimney can be a costly and time-consuming exercise and something that you do not want to repeat because of a liner failing. Therefore, we do not sell cheap inferior flue liners, and only offer our customers the best liner on the market, but still at a fantastic price. Duraflue is designed for professional trade-fitters desiring a premium product for chimney lining.

Duraflue chimney liner is created from TWO compressed stainless-steel layers. This unique laminate stays smooth when the product is passed around chimney bends (with a lesser-quality liner the laminate usually comes apart when dragged through bends - allowing acids from soot deposits to enter and later cause corrosion).
