The 7" Premium Forever Flex Pre-Insulated Chimney Liner is a durable,
flexible liner. It provides zero clearance inside of a masonry chimney.
Pre-insulated pipe makes the job easier and saves time. That means no
more applying adhesive, cutting and wrapping the insulation onto the
pipe, then covering it with a wire mesh to hold the insulation in place.
In order for a UL listing (safety testing) to be valid on any brand of
chimney liner, it must be insulated when installed into the chimney.
This means either purchasing a pre-insulated liner or insulating it on
the job site.
The Forever Flex liner is constructed of 316Ti stainless steel inside
and out with a .006 thickness. 316Ti is a higher grade of stainless
steel than 304L. This liner can be used when venting wood,
pellet, oil, coal or gas burning appliances. A seven-ply seam with ten
corrugations between each reinforced seam makes it very flexible.
This chimney liner is backed by the
manufacturer's lifetime warranty (wood and pellet). Installation and
maintenance requirements must be followed to validate the warranty. The
warranty is transferable should you sell your home.
The Forever Flex chimney liner is
safety tested to UL standard 1777 by Underwriter's Laboratories.
