All about Chimney Liners

Without a liner, your chimney would be a major safety hazard. Chimney liners keep heat away from any potentially combustible areas of the home, preventing fires and protecting your family. Homes in the U.S. with chimneys are required to have a flue liner in place, but your flue liner may not necessarily be in the best shape it can be. A chimney professional can tell you what needs to be done in order to maintain your chimney liner, and whether yours requires a replacement, but here is a bit more information to keep you up-to-date about this important safety feature.

Types of Chimney Liners

Chimney liners are built of three different types of material: clay tiles, metal, or cast-in-place cement. Which type is in your chimney will depend on whether the chimney is newly constructed, the space in the chimney, cost considerations, and the previous material used.

  • Clay Tile – Clay tile is usually used for newly constructed chimneys, as these are difficult to put in place after construction. Clay tiles are long-lasting, sturdy, and cost-effective (during construction), but other options are usually recommended because they are difficult to replace.
  • Metal – Metal flue liners are a good replacement for any type of existing liner, and steel can hold up to the byproducts of any type of fuel. Insulation is usually necessary for it to be effective.
  • Cast-in-Place – It is easier to replace clay tiles with a cast-in-place liner, which is poured directly inside the chimney walls or the flue liner. Cast-in-place liners are ideal in many situations, but in no case is it a do-it-yourself type of product, and a professional can tell you which type of liner is best for your situation.

Professional Maintenance Is Vital

One of the things that is important to keep in mind is that maintenance is key to keeping your flue liner in good condition. Have a professional inspect and clean your chimney from time to time to prevent creosote buildup and to find out whether your flue liner is in need of replacement.
