Inside your chimney is a passage for flue gases, created by combustion, to exit your home. This passage is called a liner. However, some chimneys do not have a liner and flue gases travel inside the bricks that make up the chimney.
When there is no liner in your chimney or when any of the flue tiles become cracked or broken, we recommend installing a stainless steel chimney liner. Our liners are appropriate for furnace flues, fireplace flues, and have a lifetime warranty.
