I have my Forno Bravo Casa2G80 stove on top of its insulation and with the cooking floor in place. I'll cement the joints - that seems no problem. Then the insulation gets wrapped on the stove and it's at this point I run into questions. I want to create a finished dome in stucco, including a flat front face and square stucco chimney enclosure (around the stainless pipe that came with the stove, but should I swap this out for double-walled?) and a shell over the dome that de-emphasizes the low spot at the oven door (so, built up more over the neck than the dome itself). I think I can use metal lath for the front face and the chimney surround. Creating the dome cover is where I'm puzzled. I've read materials on this forum that suggest using a welded frame of thin rebar, with screen mounted to the frame and hardware cloth on top of that and vermiculite to fill the irregularities between the frame/screen/cloth and the bat insulation. Others seem less concerned with creating such a frame system and seem to say something less is adequate, perhaps just sturdy hardware cloth with heavy duty aluminum foil between the bat insulation and the hardware cloth. Is there a preferred method for creating a substrate for a stucco shell that will resist cracking? A reason for keeping the stucco off the insulation (or a particular distance from it)? A list of the methods other folks have used successfully?
