Chimney liners are actually quite simple. Chimney lining is the clay, ceramic, or metal system installed inside your chimney. It’s designed to contain the heat and combustion products produced by a fireplace (like carbon monoxide, carbon dioxide, sulfur oxides, and nitrogen oxides) and directs them out of your chimney. The lining also lowers the risk of accidental fires by protecting the chimney walls and surrounding construction from heat corrosion. In short, chimney liners make your fireplace safe and chimney more efficient.
