Learn the Facts about Chimney Relining

Share

 

The chimney’s lining is one of the most important things to keep in mind when you’re having the chimney inspected or cleaned. It takes a lot of abuse from smoke, heat, and creosote. They occasionally take more damage than they can handle and need to be repaired or replaced; this is the process of chimney relining. Here are a few more facts about chimney relining that you should know:

  1. Chimney liners are also called the flue.
  2. The most common type of flue is made of clay tiles, although some may be metal or cast-in-place cement.
  3. The flue is a working part of the chimney just like all other parts. It is designed to withstand a lot of heat and effectively remove smoke and dangerous gases from your home.
  4. They protect the masonry and surrounding structure from the extreme heat that can cause structure fires.

The Three Types of Flue

Clay tiles are the most popular type of chimney liner. They’re the most popular liner for new chimney builds. They are inexpensive, readily available, and work very well when properly maintained. They’re susceptible to damage including cracks, breaks, and impact damage. Any damaged flue tiles need to be replaced as soon as possible to prevent the risk of fire and carbon monoxide poisoning.

Metal liners are generally made of stainless steel or aluminum. They’re primarily used to repair existing flues that have taken damage of some sort. They’re rarely used as part of a new chimney installation. They are safe for most types of fuel including wood, gas, or oil. It is relatively inexpensive and a good alternative to clay tile when full replacement chimney liner replacement is required.

Cast-in-place liners are lightweight cement products that are literally poured down into the chimney and cast in place meaning they dry within the chimney. They’re a wonderful way to add structural integrity to an aging chimney. They’re suitable for use with all types of fuel.
