During your annual Chimney Cleaning and Safety Inspection, did your sweep recommend you replace the refractory panels? If so, chances are there was a crack in the refractory panels. Although a crack may not seem like an issue, it will defiantly affect the efficiency of your fireplace. If the crack is deep enough, pieces have the potential to break apart reducing the heat pushed back into your home.

Below is a brief overview of what refractory panels are and what they do:

What are refractory panels?

Typically there are four sheets of refractory panel bricks attached to the sides of your chimney. Built with heat resistant materials, they are able to withstand the hottest of temperatures.

How do refractory panels work in the chimney?

Refractory panels reflect the fire’s heat back into your home, giving you that added warmth, while keeping your heating bills down. The panels will also provide extra protection in the firebox from extreme temperatures.

When and why would refractory panels need to be replaced?

  • Aesthetically – New refractory panels will give a clean “brick-like” look throughout the
  • Cracked panels – Cracks can greatly reduce the protection provided by the panels, increasing a potential fire hazard.
  • Damaged panels – Damaged refractory panels cannot push the same amount of heat back into the room, which will increase heating bills.

Replacement of these panels should always be completed by an experienced professional. After the refractory panels are replaced, homeowners should refrain from using the chimney for at least 24 hours. This will allow enough time for the panels to reach room temperature.
