Chimney Liners

Chimney Liner is a clay-tile or metal liner that is inserted into a chimney. Among the best reasons for relining a masonry chimney is that it wasn’t built right in the first place—that is, without a flue liner, a material that provides a smooth, relatively seamless surface as well as insulation. Historically, well-built chimneys were parged with mortar to line the flue, and clay tiles have been standard liners since the 1900s. Nonetheless, linerless chimneys remain very common in old houses as well as newer ones. Builders and heating equipment installers don’t always keep up with recommended practices, and even if they do, they may not take the trouble to observe them. If your chimney does have a liner, another reason you may need to reline is because it is defective. Age and use can open cracks in tiles, and combustion gases combined with rain will erode parging and masonry joints between bricks or stones. If the preponderance of evidence points to relining, you’ve got some choices to consider. You can 1) reconstruct clay tile flues with new clay tile liners, 2) reinforce the chimney and create new flues with poured-cement liners, or 3) reline existing flues and run new ones with metal flue liners. Each method has its benefits, limitations, and challenges. The approach you ultimately choose should be the one that’s best suited to the problems of the particular chimney and the appliances vented through it.

Flue Liners

A flue liner is a structural element inside a chimney flue which can provide a number of functions. While flue liners are not necessarily required for all chimney flues, they can be extremely useful, and sometimes for safety reasons they are strongly recommended. People who are not sure about whether their flues have or need flue liners can ask for a chimney inspection, during which the condition of the chimney and the current use of the chimney will be assessed and safety concerns will be identified.
