All About Chimney Liners

While your chimney liner may be one of the most important parts of the chimney system, it is often one of the most overlooked — one reason being because you can’t exactly look at it! The liner is the part that covers the inside of the masonry from top to bottom, working as a protective barrier.  Regardless if your chimney is used to vent a woodstove, fireplace or furnace, most have clay flue tiles stacked on top of one another, forming a liner called the flue. Your flue liner should be sealed tightly to protect your chimney. Over time, dangers can develop that compromise the efficiency and safety of your home’s chimney. The chimney liner must be maintained and kept in good condition or else smoke, heat, and CO will enter the airspace of your chimney and walls causing serious safety concerns, including, but not limited to: carbon monoxide poisoning and fire beyond the designated fire walls. Neighborhood Chimney Services is here to help!

 

THE LINER’S JOB:

The chimney liner actually has multiple jobs, and they’re all very important.    

  • First, the liner protects the masonry from the corrosive chemical byproducts of the fire. If allowed to sit on the masonry, soot and creosote can damage it from the inside out.
  • The liner also creates a properly-sized vent for your fireplace. Without the liner, the chimney flue may be too large, making the chimney inefficient. Or it may be rough, disrupting airflow and promoting buildups.
  • Finally, the liner serves as a barrier, protecting the home from harmful chemicals that can pass through the masonry and keeping heat from transferring to building materials in the house.

According to the CSIA (www.csia.org), problems such as gaps, cracks and spalling in your chimney’s flue can present serious risks to your home and family, because your chimney can no longer perform its intended function – to safely contain and vent the products of combustion to the outside.  We are Wolcott’s only CSIA Certified Company in town!
