Clay Chimney Liners – This type of liner is usually installed during the construction of a home. This is an older method of chimney lining and has been used in homes since the early 20th century.  Clay tile is a tried and true type of chimney liner that is able to withstand extremely high temperatures without compromise. The clay lining is capable of resisting the harmful materials that travel up through the flue into the air above. Best of all, the clay material is very affordable and the liner can last up to 5 decades without needing to be replaced.

There are also some downsides to clay chimney liners.  For starters, The clay is arranged in rectangular tiles and therefore does not create a smooth interior. Air can get stuck in the spaces and can effect the natural draft inside your chimney. If the tiles get too old, they can begin to crack which puts you at risk for a house fire.
