Why Would You Need a Stainless Steel Chimney Liner?

Share with friends


A stainless steel chimney liner will make your chimney perform more safely and efficiently. A liner fits inside the chimney flue to protect the bricks and mortar from the soot and creosote created by fires. Many older homes do not have liners inside their chimneys.

Gases created by fires can corrode the chimney’s bricks and mortar, which is the cement-like material in the joints between the bricks that helps bind them together. These acidic gases can eat at the mortar joints. When the mortar is compromised it can lead to fires or dangerous carbon monoxide leaking into the home. Also, unlined chimneys can pose a safety hazard because creosote can build up on the sides of chimney. Creosote is flammable and if too much is present it can catch fire inside the chimney.

Chimney liners also improve fireplace efficiency by providing a correctly-sized chimney flue, which is the chamber inside the chimney. Chimneys not only allow dangerous gases to escape from the home when the fireplace is in use, they also are responsible for creating the draft needed for use of the fireplace.

If the flue is too big or too small, it can hinder the flow of air in and out of the chimney. This can lead to smoke billowing into the home when fires are burned. Also, if the flue of a chimney attached to a stove is too big it can lead to overfiring of the stove.

There are several materials used for chimney liners, and a professional chimney cleaning company can recommend one after an inspection. Stainless steel is one of the most popular materials.

A stainless steel chimney liner is suitable for fireplaces and stoves that burn wood, gas or oil. Stainless is a good idea if you need to install or replace a chimney liner but don’t want to choose the expensive option of rebuilding a clay or terra cotta liner.

The stainless steel liner comes in flexible or rigid varieties. It is usually in the shape of a tube and is inserted in the existing chimney. The liner creates a new flue. Of the metals available, stainless steel is the most common. Some other metal chimney liners include titanium, which adds some resistance to heat and corrosion, or aluminum.

Stainless steel chimney liners resist corrosion, rusting and staining. The metal maintains its strength and structural integrity even in the high temperatures inside the chimney. They are also easy to clean and are inexpensive, typically costing $20 to $40 per foot.
