About clay chimney liners
There are 3 types of chimney liners: clay liners, metal liners and concrete liners. Depending on your needs, you will have to choose from one of these types. The liner is used to insulate the chimney flue from the heat coming from the fireplace.
The material used for liners can be either poured concrete, clay tiles or flexible/rigid steel. Installing each type of liner is different. You will choose the material you need to use depending on the fuel you use. For example, a clay tile liner will not work with a gas stove.
Clay tile liners are considered to be the least expensive of all types of liners. The steel liners come in kits and so lower the labor needed and the costs. The concrete liners are also considered relatively cheap but the labor needed when installing this liner is very costly. Some people consider that installing any liner is an easy task for about anyone, whilst some consider hiring a professional for the job is the right way to go.
Each material has an average lifespan of 50 years. Some metal liners have warranties that sometimes outlast the ownership of a house, but can be transferred to the new owner.
A professional’s help is needed when installing almost all types of liners. The steel liner is considered the easiest to install. A clay tile chimney is very difficult to install due to the fact that it requires a lot of customization depending on the chimney. Poured concrete liners need a professional to install them by pouring in the right shape and size. The poured liner is very effective for chimneys with bends and curves. Increase the stability of an old chimney using concrete to reinforce it.
Clay tile liners can’t be used for fireplaces that use gas as fuel. Steel liners are the best choice in this case. For pellet stoves and wood stoves, the clay tile and poured concrete liners are the best choice.
The chimney liner is a very important piece of the chimney exhaust system. If you don’t think you can handle the installation and maintenance required, it is best you hire a professional.
