Chimney Lining Systems

Chimney liners are mandatory in most countries worldwide. These liners are made from clay, metal or ceramics and they secure the inside of the chimney from any damage that corrosion, smoke or heat can deliver to the chimney structure.

Chimneys without adequate liners have proven over and over again to be extremely dangerous, unsafe, and the cause for 75% of fire and smoke related deaths during the beginning of the 21st century.

The main function of a chimney liner is to avoid the transfer of heat from the fireplace to the house structure.  Protecting the masonry is the second function of a chimney liner.

Burned gases can penetrate the masonry and reduce the life of the chimney. In time, the mortar that holds the bricks together will crack open and let the heat and gases out into the structure of the house. This can ignite fires or even poison the inhabitants with deadly carbon monoxide fumes.

The third function of a chimney liner is to provide a steady flow of flue from the fireplace to the exterior.  By this, it can be assured not only that the burned gases are expelled, but it can provide a good draft of air that increases the efficiency of the stoves or fireplaces where they are used.

Keep in mind to use the size required for the chimney liner provided by the stove label or a specialist. Using wrong sizes can make your stove accumulate larger creosote or carbon monoxide buildup than desired.

Made from aluminum or stainless steel, the metal chimney liners are the perfect choice for upgrading conventional chimneys. They usually are covered with thermal protection layers and, if properly installed, are well suited to deal with extreme hot temperatures or gas burner fumes.
