Fireside Chimney Supply's FireFlex HeavyWall chimney lining systems are made of .017 316L stainless steel and are used for all fuels.
Our FireFlex HeavyWall 316L Stainless Steel chimney liner system is designed to reline existing chimneys or be used in new construction. These heavy duty chimney liners are manufactured using the highest grade mill certified alloys. Each steel chimney liner kit is manufactured with a continuous strip of stainless steel, interlocked and diagonally crimped to produce a gas and water tight system of superior strength. Each heavy duty chimney liner features 7 ply seams and 10 corrugations between each seam which are designed to deliver the flexibility needed to get the job done.
PLEASE NOTE: When installing HeavyWall Chimney Liners it is recommended to have additional help for the installation process. HeavyWall liners weigh approximately 3 times the weight of the basic liner kit. This is due to the thickness of the liner being 3 times the thickness of the basic kit (.017 compared to .006). Please use the following formula to get the approximate weight.
.417 X Diameter X Length = Weight

We strongly recommend using a polypropylene chimney brush versus any metal chimney brush. Polypropylene is non-abrasive and does not scrape the interior of the chimney liner. Metal brushes have an adverse effect on the liner.
