A chimney liner is a protective lining installed inside a chimney. Its primary purpose is to direct smoke and gases from a fireplace or stove safely outside, preventing them from entering the home. Chimney liners can be made from various materials, including clay, metal, or ceramic, and they help improve the efficiency of the chimney while reducing the risk of chimney fires. In addition to safety, chimney liners also help to protect the chimney structure from heat and corrosion caused by combustion byproducts. Properly installed liners can enhance the draft, making it easier for smoke to exit the home. Regular inspections and maintenance of chimney liners are essential for ensuring their effectiveness and longevity.
