Chimney Liner Facts

Your chimney is made up of several important components that make it function efficiently and safely. One of these parts is the chimney liner. Without a liner, your chimney can be a hazard for accidental fires and for carbon monoxide leaks. Safety codes now require thatliners must be included when chimneys are built; however, homes built before 1950 were not held to these same standards. According to the Chimney Safety Institute of America (CSIA), the building safety codes were updated because of studies conducted by the National Bureau of Standards (NBS). In the 1940’s and the 1980’s they found that constructing a chimney without a liner was so unsafe that it was “a little less than criminal.” All American Chimney Service is proud to offer chimney relining services to the Louisville area. So, we would like to tell you more about the importance of chimney liners.

What are the functions of a chimney liner?

Chimney liners serve three important functions. They protect the combustible parts of your home from heat transfer. The NBS found that without a liner, heat transferred so quickly that adjacent woodwork ignited into flames within only three and a half hours. Another function of a chimney liner? Protecting the bricks and mortar of the chimney from the corrosive byproducts of combustion. If there is no liner, the toxic combustion gases can eat away at the masonry materials to cause extensive damage. Your chimney liner is also important because it provides a correctly sized flue for your heating appliance. In order to work efficiently, modern wood-burning and gas fireplace inserts need a flue that matches their size. A stainless steel liner can be custom fitted to allow proper drafting.

What are the different types of chimney liners?

There are three kinds of liners, and All American Chimney Service can help you decide which is the right one for your chimney. According to the CSIA, the most common type of liner for masonry chimneys is the clay tile liner. While these liners are easy to maintain, they can be difficult and costly to repair using traditional methods. We use a more economical service, the HeatShield Repair and Resurfacing System, to restore clay tile liners.

The most common type of liner for prefabricated chimneys is the stainless steel liner. This type of liner is also typically used with fireplace inserts. Extremely durable and safe, stainless steel liners are often recommended when upgrading and repairing existing chimneys. The last type of chimney liner is the cast-in-place, which is a lightweight cement-like product. This type of liner can be used with all types of fuels and can restore the structural integrity of older chimneys.
