    • 316Ti Pre-Insulated Chimney Liner

    Stainless steel chimney liners should be insulated to provide the best draft for your appliance and meet National Fire Safety Codes.  Chimney liners that are pre-insulated are the easiest to install.

    Pre-Insulated Forever Flex is manufactured from 430 stainless steel in the outer skin and 316Ti inner stainless steel liner.

    It comes ready to install with Olympia Chimney Supply's non-carcinogenic Super Wrap Insulation Blanket already wrapped around the liner. It is convenient for the installer; saving both time and money.

    It carries the Forever Warranty, is UL/ULC listed, has 0 to 0 clearance within a masonry chimney.

    We also have HomeSaver Ultra-Pro Pre-Insulated Liners and kits shown at the bottom of this page. 

    • Patent-pending cover and insulation system features
    • Spiral wrap insulation allows liner to freely flex at any point
    • Spiral wrap and taller cover corrugation height eliminates the stiffness experienced with other liners
    • Corrugation profile provides durability in the outer shell
    • 316-Ti liner, aluminum outer shell
    • UL pending
    • Lifetime Transferable Warranty
    • All sizes except 8'' fit between the wheel wells of a pickup or van
    • OD 1-1/2'' larger than ID
