A chimney liner is a flue lining in a masonry chimney that contains the combustion products and directs them to the outside atmosphere, protecting the chimney walls from heat and corrosion. The installation of liners has been highly recommended, as it has a significant part to play in protecting the chimney and surrounding structures. In fact, the majority of fire codes now mandate chimney liner installation. A Step in Time Chimney Sweeps is a Chimney liner installation company that provides extensive chimney sweep services.
Why Should You Look For Chimney Liner Installation?
Chimney liners are extremely important for the following reasons:
- Preventing the heat transfer to combustibles – A chimney without a liner allows the heat to pass through the chimney, which could result in the combustible materials surrounding the chimney catching fire.
- Protecting the masonry from corrosion – If the flue gases penetrate through the brick and mortar, it can weaken the structure of the chimney and ultimately result in reducing the usable chimney life. The byproducts that result from the combustion of wood in your fireplace are harmful to the chimney, as they are acidic in nature and could erode the chimney. This erosion reduces the strength of mortar joints from inside the chimney structure and allows heat to escape through the walls.
