What A Flue Liner Does For Your Chimney
In the early years of chimney design and construction, chimneys were built without a lining. As advancements were made by the home heating industry (to lessen fire dangers and improve efficiency), it became clear what a poor decision that was. Not only is the draft in a chimney without a flue lining impeded by masonry imperfections, but heat and by-products can easily escape into the walls or living space of the residence. These masonry imperfections are quickly made worse by the impacts of heat, combustion by-products and moisture. To put it simply, unlined chimneys are much less effective and much more dangerous.
A chimney liner creates a smooth surface that allows gases to move up and out of the chimney much easier and even more effectively. It also gives a strong layer of protection that keeps your chimney masonry in better shape for longer, and while doing so, lessens the possibilities of fire hazards. Added up, the chimney liner is one of the most important parts of your chimney system. And having a chimney liner that’s installed correctly, sized accurately and maintained properly is key to your chimney system being in the best state possible.
