Stainless Steel Chimney Relining

According to the NFPA (National Fire Prevention Association) the National Bureau of Standards (NBS) and a host of other professional organizations, unlined chimneys (both fireplace and gas heating exhaust flues) are deemed unsafe. 

The installation of flue lining has been recommended since the early part of this century, and fire codes in most states now mandate liners. In addition to clay liners, metal chimney liners (usually stainless steel or aluminum) were created to address safety concerns with chimneys.

Today, stainless steel liners are primarily used to upgrade or repair existing chimneys and are installed in new chimneys. Stainless steel liners are great for use in wood, gas, or oil burning appliances, while aluminum liners are an inexpensive alternative for some medium efficiency gas applications. U.L. stainless steel liners are valued for their ability to withstand normal fireplace temperatures. Stainless steel liner systems are tested by the global independent safety science company Underwriters Laboratory (U.L.) and are extremely safe and durable if installed and maintained by a chimney professional. Most stainless steel liners come with a lifetime guarantee when professionally installed! 

What is a chimney liner and what does it do?

A chimney flue liner is a clay, ceramic, or metal conduit installed inside a chimney, designed to contain combustion products, directing them to the outside thus protecting home and chimney walls from heat and corrosion. 

Chimney liners serve the following purposes::

  • Protect houses from heat transfer to combustibles. Tests confirmed that unlined chimneys allowed heat to move through the chimney so rapidly that nearby woodwork caught fire in only 3 and 1/2 hours.
  • Protect masonry from the corrosive byproducts of combustion. When acidic flue gases are allowed to penetrate to brick and mortar, there’s a significant reduction in the usable life of the chimney.
  • Provide a correctly-sized flue for maximum and optimum efficiency. Wood stoves, gas or oil furnaces require a correctly-sized flue to perform properly. An incorrectly-sized liner can lead to excessive creosote buildup in wood-burning stoves and the production of carbon monoxide with conventional fuels.
