SmartFlex Chimney Liner & Kits

SmartFlex Chimney Liner & Kits

SmartFlex Chimney Liners are the professionals choice for relining. Manufactured to the highest standards right here in the USA. Flexible or rigid lining is available to make a lifetime repair for your chimney. The standard stainless steel liner is the most flexible liner and is the easiest to work with. It is the go-to choice for all fuel relining. Smoothwall liner is available for applications where you are tight on getting the right size liner to fit. Smoothwall liner has 20% less drag than corrugated liner, giving you more flexibility in sizing a proper liner. Rigid liner offers these same benefits, but is used in applications where the chimney does not have any offsets. All Stainless Steel SmartFlex liners come with a lifetime warranty.
