Different Types of Chimney Flue Liners

If you own a chimney, you are likely aware of the role a flue liner plays in keeping your home safe. Liners help to control the heat that a fireplace produces, as well as work to keep toxins and various harmful gases away from the home. On top of this, they keep everything running as efficiently as possible and protect your masonry from excess deterioration.

Many know the importance of a chimney flue, but do not know where to start, as far as replacing or repairing one. There are multiple options, so finding what works best for your needs is important. There are three main types that professionals will be able to install. Check them out below.


Clay options are used in many chimneys due to their reputation for durability and for being low cost. These liners are more suited to the classic, masonry fireplaces, and they are not always known for standing the test of time. The way they absorb heat will often cause them to crack, thus requiring repairs before any fires are built. If you have plans to use your fireplace in the near future and you have a clay flue liner, be sure to schedule a check-up to ensure everything is safe for use.

A clay liner will perform well in a fireplace, but typically requires a lot of extra maintenance. If you have an older fireplace and have the time to perform regular check-ups and upkeep, a clay option would work fine for your set-up.


If you would like to go with a metal option for your chimney, then stainless steel would be the best choice to invest in. This option will typically work better for maintaining appropriate levels of heat within the chimney and does not require as much maintenance as a clay liner might. They are also very safe and you can rest easy knowing that you are not putting your family at risk. There is little chance of cracks and holes forming in a metal liner, so it may be a better choice for those with a busy lifestyle.


A cast-in-place liner is cement-based and is typically used in a chimney that has some cracks or other damage. They are a more durable option and can improve the overall structure of the chimney, ensuring that your home stays safe. These liners work well with any fuel type and are great for homeowners looking for something more permanent. Their ability to withstand just about every kind of gas or acid that a fireplace may face makes them a desired option by many.

No matter the type of chimney flue liner you pick, having a professional install it will always be your best bet. If anything is even a little bit off, your entire chimney will function much less efficiently and you could be putting your home and family at risk.
