Fireplace heat shields - replacements?
I have a 1989 Fuqua triplewide manufactured home. The built-in fireplace uses an unusual kind of heat shielding in the firebox. Between the log rack and the walls of the enclosure are three panels, about 1/2" thick and 18" on each side, made of wire-reinforced concrete with a faux brick pattern. These apparently serve to shield the fireplace box from the fire's radiant heat. The panels are falling apart now. Would somebody suggest a source for replacements, please? Thanks!
