Why is a chimney liner important?
Most chimneys are built with terra cotta flue liners inside of the brick/stone structure. The liner acts as a gas tight and heat resistant insulator. When a liner becomes cracked or otherwise damaged, there can be heat transfered through it to the masonry part of the chimney. The chimney comes in direct contact with the structure of the home, which is usually wood. When this contact occurs, there is risk of damage to your home’s structure. A liner made of stainless steel or aluminum is inserted throughout the length of the enitre chimney, and connects to the appliance, furnace, woodstove, or fireplace. The unit will now vent throught the liner, solving most draft and safety concerns.
