Thermo-Rite’s stock Z-Doors are made as inside fits. We use Air Studs™ or an Air Draft Bar™ to elevate the frame so that it maintains the cooling air intakes located inside the firebox. In most applications, we allow an air space between the outside of the enclosure and the firebox opening. The Z-Door is a sleek, full-framed, tarnish free anodized aluminum enclosure.


Z-Decor is an anodized aluminum enclosure with a  3/4″ wide frame. It is available as an inside fit only.  Air space is allowed on the sides, top, bottom or combination to provide the same air flow as the manufacturer of the zero clearance fireplace.


The Thin-Line is a welded 3/4″ steel angle enclosure. It is available as an inside fit only.
