Our Rock-Flex Deluxe Smooth Wall 316 stainless steel chimney liner is gaining in popularity due to its superior flexibility and increased BTU capacity. Its smooth interior design allows for more airflow, adding back the 20% drag factor that's lost in traditional corrugated liners. UL listed in the USA and Canada and since it's made of 7 ply 316 stainless steel and 2 inner linings (.013 total thickness), it's great for any application including wood, pellet, gas, oil, and coal burning appliances.You can use it with all of our round liner components. 100% stainless steel and 100% made in the USA with the highest quality stainless steel.
Note: Because of its special construction, smooth wall flexible liner cannot be ovalized or shaped in any way. If you need a shaped liner, please see our oval, square, or rectangle chimney liner kits.
