Two Considerable Fireplace Chimney Liner Options Two Considerable Fireplace Chimney Liner Options
A fireplace chimney liner is a device placed inside of the chimney which helps to expel soot, smoke, and ash from the fireplace to the outside of the home. There are two major types of liners available today, which both have considerable advantages and disadvantages. The information below will describe each option, its advantages and disadvantages, and its approximate cost for your home.
The most common fireplace chimney liner used in newer homes consists of clay. In homes where the fireplace temperatures will not reach extremely high levels, a clay liner is adequate and will suffice. If, however, the clay is exposed high heat levels from the fireplace, it can crack or even disintegrate. Additionally, clay is also not as efficient at expelling soot, smoke, and ash because some of these materials are absorbed by the clay. However, it should be noted that clay liners are very inexpensive and can be a worthwhile option if you do not intend to create large fires in your fireplace.
Metal chimney liners are used in some new home construction and almost always are used to replace an existing chimney liner. Stainless steel and aluminum are the two most commonly used types of metal because they are resilient to moisture and heat. Stainless steel is especially popular due to the fact that it can withstand temperatures of up to 2100 degrees. Aluminum is less expensive than the steel, but offers a far lower maximum temperature. Both options are extremely resistant to moisture and are non-porous, so they allow for a better flow of the fireplace's residue. However, both of these options are pretty expensive and will be much more costly than the clay liner.
