About the Inner and Outer Liners

Fabricated with a 316Ti stainless steel inner liner, and a 430 stainless steel outer liner, you can't go wrong with this choice. The inner liner will vent the flue gases, while the outer liner will protect the insulation as it's being installed down the chimney flue. Moreover, with 7 ply seams and 10 corrugations per seam, it is a very durable liner that is air and water tight. 

The purpose of the outer lining is to protect the insulation and keep it intact during installation. The 430 stainless steel outer lining isn't directly in contact with the emissions and by-products like the inner lining is. By using 430 stainless steel outer lining, you will not find a Pre-Insulated flue liner as economical and affordable as ours, without compromising on quality.

Not only is our insulated chimney liner made from prime stainless steel, but also features 1/2" thick insulation between the two linings. Most important, this ensures the flue gases stay hot and less creosote will build inside. By choosing to install a pre-insulated chimney liner, you avoid time and hassle with wrapping insulation around your flex liner.

Measuring & Installing Your Insulated Chimney Liner Kit

Measuring for your stainless steel insulated chimney liner is one of the most important steps. Specifically, measure the exact inside measurements of the chimney flue or brick chimney, this will ensure the chimney liner will fit down your masonry flue. Add 1.25” to the liner size for the outside diameter (Ex: The 6” liner has a 7.25” Outer Diameter).

Be sure the proper size liner, sized to the appliance you are connecting to, will fit down your current masonry chimney. Here is a link to our helpful measuring guides and a link to our Chimney Liner Size Calculator.
