chimney linersOur chimney experts at A Sweep Across the Bay in Sarasota can tell you which of the 3 types of chimney liners will be best for your home. According to a Chimneys.com article, there are several factors that guide which flue liner will work for your chimney, including the type of chimney you have, the kind of flue appliance, and how it’s going to be used.

Everyone wants a fireplace in their home but most people don’t really know too much about chimneys. If you want to build a new one or re-line your chimney there are some things that are important to know because you don’t want to end up with a liner that may be inadequate for your needs.

Did you know that current construction and safety standards require a flue liner in all chimneys? Before 1930, a flue liner was not required. It is very dangerous to use a fireplace or wood stove without a flue liner. Sometimes a house may have a flue but it is built the wrong way or the lining has deteriorated. Either way, it can be very unsafe.

If you’re not sure if your chimney has a liner or feel like your chimney liner may not be working properly, our experts can inspect your chimney and recommend the right one. What happens is, if there is a crack in the flue, the combustible parts of the home are exposed and create a high risk of a fire. Another concern about flues is if they do not fit it could potentially cause carbon monoxide poisoning, which is tasteless, odorless, and invisible.

You really should have your liner inspected every year, cleaned periodically and replaced if it is damaged or improperly built. There are three types of flue liners that you should consider, including metal flue liners, cast-in-place flue liners, and clay chimney flue liners. Let’s take a look at the differences between these liners.

Metal Chimney Liners

There are several kinds of metal chimney flue liners. Rigid metal flue pipes can be used with straight chimneys that have no bends or offsets, but flexible liners are available in a wide range of diameters.  Metal flue liners need insulation as well. Available in all types and sizes and easier to install, metal stainless steel flue liners are recommended by many fire protection experts. Aluminum liners are cheaper than stainless steel liners, but can only be used for some medium-efficiency gas appliances. Steel flue liners can be used for all types of fuel-burning, including gas, oil, and firewood, providing excellent protection.

Cast-in-Place Chimney Liners

If you haven’t heard of a cast-in-place liner, it is a flue liner constructed with poured cement. It can be less invasive, require less labor, and be cheaper than having to rebuild a clay tile liner. It works with all types of fuel-burning chimneys and can handle the harmful effects of acids, condensation, and heat. A cast-in-place flue liner and clay chimney flue liners both last for about 50 years.

Clay Chimney Liners

Clay tiles are less expensive and last a long time, which makes them a very popular flue liner. As we mentioned, clay tiles can last for 50 years but if you do need to replace a clay liner it is very labor intensive because you have to tear out the clay tiles (sometimes the chimney wall has to be torn out also) and install new ones.
