Ceramic liner is the faux brick found within gas fireplaces. They are lightweight and cannot withstand the heat of a wood fire.
All of our ceramic fiber is fireplace model-specific. For example, this item is for use only with Empire's 42" 42" Keystone
You would need to replace your cracked refractory panel, which, I assume is within a woodburning fireplace.
We do offer some universal refractory panels that will work for any woodburning fireplace. Please see the following links:
Hargrove Replacement Fireplace Refractory Panel - 24 inch X 28 inch
Hargrove Replacement Fireplace Refractory Panels - 24 inch X 40 inch - Set of 2
These panels are about 3/4" thick and can be cut down to the size you need with a masonry blade.
