As an economical option for lining a straight chimney, it doesn't get much better than this. The 15 foot long liner itself is made of .006 inch thick stainless steel, making it very lightweight, but also extremely strong compared to comparably sized liners. The limited lifetime warranty is a really reassuring bonus, and the compatibility with other DuraFlex components makes application simple. That's why, for overall function and cost-effectiveness, homeowners have a tough time finding a better venting solution than a DuraFlex SS Stainless Steel Chimney Liner.

Liner is of good quality steel and is sufficiently flexible for tight bends. Get the DuraFlex connectors at the same time to make sure you get a good fit. Other brands might be slightly off in size and steel doesn't stretch much at all.
