A chimney liner
A chimney liner is a metal, ceramic or clay insert that protects the chimney from these byproducts of a burning fire. It also protects the chimney walls from heat and corrosion. If the chimney becomes too hot or damaged in any way, the surrounding wood is liable to catch fire.
Testing has revealed that unlined chimneys are very hazardous. In the US, homes containing a fireplace that were built after 1940 must have a chimney liner, and they must be replaced if broken or cracked.
Chimney liners come in three main types:
1. The traditional material for chimney liners is clay tiles. This is an inexpensive option, easily obtainable, and works satisfactorily in an open fireplace chimney that is suitably kept up.
2. A metal chimney liner is commonly made from aluminum or stainless steel, and is mostly used for repairing or upgrading an existing chimney. When installed correctly, a metal liner has a high safety rating and is very durable.
3. Then there’s the cast-in-place liner. This is a lightweight product made from a material resembling cement. Once installed inside the chimney, it forms a well insulated, seamless passage to allow the combustion byproducts to escape. This permanent liner can enhance the structural integrity of an older chimney, and is suitable for all kinds of fuel.
When replacing their chimney liners, most people nowadays select stainless steel because it’s much simpler to install than clay tiles. It’s available in either flexible or stiff styles.
Most people choose to have their new chimney liner professionally installed. However, there are kits available that include instructions for installation, and this can save you a lot of money. The kits usually include all the required accessories and attachments to get the job done.
If you live in an older home with a fireplace, it’s essential that you have it professionally inspected to make sure it’s up to the current standards of safety. An old chimney that’s damaged or improperly lined presents a great danger to the members of your household. And since there are a number of reasonably priced and effective ways to correct the situation, there’s really no excuse not to invest in one of these essential fireplace tools and accessories.
