Stainless Steel Chimney Liners vs. Aluminum Chimney Liners

Stainless steel chimney liners are considered to be one of the best materials to use in heating ovens or fireplaces. They are classified as metal flue liners. Another type of material found in this category includes aluminum. These materials can be easily bought from stores. They are available in kits which make it possible to select the correct metal to use and the right size to fix in a given chimney.

Rigid and Flexible Stainless Steel Chimney Liners

Stainless steel is available as rigid and flexible chimney lining material. They come in a wide range of diameter as well. Select rigid liners when working with straight chimneys. They can be used for fireplaces with diameters varying from 3' to 10 inches. When choosing rigid liners, watch out for double or triple wall chimney pipes which are designed for open chimneys.

Flexible chimney liners are also made from stainless steel. They are suitable for use in chimneys with diameters varying from 2 to 10 inches. They have corrugated surfaces which make them very easy to clean and maintain. They work very well for ovens that commonly use wood for fuel. This material is also available in different sizes to fit different lengths especially when using it for straight chimneys.


Stainless steel chimney linings are versatile as they can be efficient for use in chimneys that burn different types of fuels. These include wood, gas and oil. The reason is that different combinations are used to make the alloy which supports different degrees of temperature and corrosiveness of fuels used in chimneys.

Aluminum Chimney Liners

Aluminum is most suitable for low temperature chimneys. It is equally important to watch out on the type of fuel used in this kind of chimney. They are most effective for gas installations. Take care that only less corrosive gases are used in the chamber. This prevents damage to the aluminum lining and it allows it to last for long duration.

Cost Benefits

The benefit of installing either stainless steel or aluminum chimney liners is that they are cost effective when used to repair old furnaces. Get one that fits the needs or qualities of a particular fireplace. Some important factors to consider include the type of fuel used in the heating oven, the degree of heat required and the effectiveness of such material in regard to safety.

Metal chimney liners such as stainless steel and aluminum are cost effective when used as replacement material for brick or clay fireplaces. They are easy to install as they are readily available from stores. Buying a chimney liner that has the correct dimensions as that of the furnace makes it easy to install. The job can take a few days to complete.


Metal chimney liners are popular as they enhance safety. They are better in minimizing the amount of carbon monoxide seeping in the house. Stainless steel liners are useful in preventing the accumulation of creosote in chimneys. Use flexible liners in this case as they easily gather this flammable residue from wood. It can then be collected and disposed off correctly.
