Understanding the Different Types of Chimney Liners

In order for your chimney and fireplace system to work at its highest levels of safety and efficiency, all of its components need to be in good condition. One of these components, the chimney liner, has three important functions. It protects your home from high heat transfer, it keeps the bricks and mortar joints protected from the corrosive gases of combustion, and it provides a properly matched flue with your hearth heating appliance. For over 25 years, All Seasons Chimney has provided superior professional chimney maintenance, repair, and installation services, including Different Types of Chimney Liners - Poughkeepsie NY - All Seasons Chimney chimney relining, to the lower Hudson Valley area. We would like to tell you more about the three different types of chimney liners and their advantages and disadvantages.


If you have an older home with a masonry chimney, you likely have a clay tile liner. According to the Chimney Safety Institute of America (CSIA), this is the most common type of chimney liner. Inexpensive and durable, clay tile liners perform very well when you regularly maintain your chimney. Following a routine chimney maintenance schedule can prolong the life of a clay tile liner; however, years of exposure to extremely high temperatures causes the tiles to crack and crumble. Fortunately, All Seasons Chimney can repair and restore the liner with our HeatShield services.


Whenever All Seasons Chimney updates fireplaces with new inserts, we usually install a new stainless steel chimney liner as well to provide a flue that matches the size of the new fireplace insert. Metal chimney liners are extremely durable and are safe to use with every fuel type. The only disadvantage of this type of liner is that it is considerably more expensive than the other types of liners; however, stainless steel chimney liners are typically guaranteed for a lifetime.


This type of chimney liner is a lightweight cement-like product that is poured into the chimney to form a seamless and smooth flue as it dries. Cast-in-place liners provide excellent insulation and can boost the stability and integrity of the chimney structure. Since this type of liner can be a challenge to install, the labor costs can be higher than average.
