What Is a Chimney Liner? Stainless Steel Chimney Liners Explained

What is a Stainless Steel Chimney Liner presented by Rockford Chimney Supply. A flue is considered part of the chimney and is where gas and smoke exits the home. Once a stainless steel chimney liner is installed, it acts as the chimney flue, safely venting emissions out of the home. It's beneficial to install a stainless steel chimney liner to prevent harmful gasses (such as carbon monoxide) from leaking into the home through cracks, to ensure an adequate draft, and to help prevent a chimney fire. Deteriorated chimneys have cracks in the tiles, bricks, and mortar and are unsafe to use. Installing a stainless steel chimney liner is the least expensive route to creating a safe and efficient chimney setup.
