At High’s Chimney we’ve found that chimney liners are perhaps the most under-appreciated part of the fireplace and flue system. That’s why we decided to write a little piece giving an overview of their function and importance.
What is a Chimney Liner
A chimney exists to carry dangerous gasses out of the home, and it needs to do so without getting over-heated. A chimney liner creates a barrier between the flue and the walls of the chimney, and its purpose is to insulate and protect the chimney. According to the Chimney Safety Institute of America, a chimney liner is defined as:
“A clay, ceramic, or metal conduit installed inside of a chimney, intended to contain the combustion products, direct them to the outside atmosphere, and protect the chimney walls from heat and corrosion.”
