What is a Fireplace Refractory?

Most houses today have prefabricated fireplaces. These fireplaces are factory-made and have fireplace panels on the bottom and sides of the firebox. These panels are made to withstand the high heat of the fire and provide strength and durability to the fireplace itself.

When these refractory panels become compromised by cracks, it poses a threat every time you use the fireplace. Even the smallest cracks put your home at risk, as the flames could penetrate into the walls or ignite from combustible materials within the firebox.

Dangers of Cracked Refractory

You probably know that the fireplace panels expand and retract as they heat and cool. This is normal. Tiny hairline cracks that occur inside the panels are also not concerning, and you can safely continue to operate your fireplace. When the cracks in the refractory panels become worrisome, is when those hairlines cracks begin to widen.

The Chimney Safety Institute of America (CSIA) warns that a cracked fireplace refractory should be replaced if the crack is 1/16 of an inch wide, or you can fit the end of a nickel into it. You should also replace fireplace refractory if the surface is abraded to 1/4 of an inch.

Be aware that the CSIA does NOT recommend repairing the refractory when cracks become significant, but replacing with original manufacture panels. Repairs of cracks to this magnitude are not dependable and can put your firebox at risk.
