Insulation.
Posted by Claude Franze (211.27.45.205)
HI,
I am in the process of building my oven and have been fortunate enough to have acquired a pallet of refractory bricks and a pallet of insulating firebricks from an auction. My question is instead of using vermiculate or ceramic blanket as an insulation over the dome would the insulating firebrick be adequate as an insulation over the dome and then cement render over to weatherproof. Also I am considering breaking up some of the insulating bricks to mix into the hearth slab on the underside instead of using vermiculite. Is this a good plan? any suggestions greatly appreaciated.
all the best,
Claude F.
