The primary purpose of chimney liner installation is to contain the byproducts of combustion, and efficiently remove them from your home.
The harmful by–products of combustion include:
- Creosote, smoke, and carbon monoxide – produced by wood-burning appliances
- Carbon monoxide – produced by gas-burning appliances
- Carbon monoxide and sulphuric acid – produced by oil-burning appliances
Reasons to Line Your Chimney, or Reline it if the Current Liner is compromised:
To Protect Your Home from Excessive Heat from the Fireplace or Flue
Creosote formation is the unavoidable byproduct of burning wood. The danger of creosote is the 450 ˚F ignition point. An average solid fuel burning appliance produces gases that leave your ﬁreplace at 300˚F to 900˚F which can cause a chimney ﬁre.
To Protect Your Chimney’s Masonry from Corrosive By–products
Testing has determined that if flue gases are allowed to penetrate a chimney’s brick and mortar, the result is a reduction in the usable life of the chimney. Acidic flue gases literally eat away at the flue and mortar joints from inside the chimney. As these joints erode, heat transfers more rapidly to the nearby combustibles and dangerous gases such as carbon monoxide can leak into your home.
To Ensure a Properly Sized Flue
An improperly lined flue can restrict the volume that is able to go up the flue.
Metal chimney liners, typically made of stainless steel or aluminum, are primarily used to upgrade and repair existing chimneys. These liner systems are U.L. Tested and listed, and are extremely safe and durable when properly installed and maintained. Traditional masonry ﬂue tiles cannot handle a high heat occurrence or the acidic moisture created by your furnace, boiler, or hot water tank. Stainless steel is suitable for wood–burning, gas, or oil applications, while aluminum is a cost-effective alternative for certain medium efficiency gas applications. High temperature insulation is always required, in conjunction with the chimney lining, to ensure long-term safety and performance.
