What Is a Flue Liner?
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.
