Dear all
I have a Stonebake Oven Company Mezzo 76 which I bought 2 years ago. Up until March it was installed on a wooden stand on concrete paving slabs in its natural uninsulated state.
We have recently moved house and the plan is to build a proper brick base and insulate it. Some people on here put their ovens on thermolite bricks and others on Calsil board. Stonebake Co. recommend the calsil on their website. I just wanted to hear people's views on which is the better option. If I put the oven on the calsil, would I be able to use it before I have insulated and rendered the dome, or would any rain damage the board?
Many thanks
Xavier

I used calsil board under my oven and it seems to warm up/hold heat fine. I also covered it with the oven/sandstone flags around the oven straight away. incidently, I left a couple of offcuts on a pile of rubble in my trailer ready to take to the tip and picked them up after it had rained. the amount of water they soaked up was unbelievable! my advice would be to make it watertight as soon as you put the calsil in, or at least cover with a tarp until you do.

Thank you. Is Calsil as good an insulator as the thermolite bricks?

G'day Calcil is a lot more efficient than the termolite block, but you pay the price. The local is " hebel" and now been running under my oven for 4 good years now and does the job really well. With any insulation the object is to encapulated the oven with insulation. The top insulation meats the bottom and seals the oven in. Regards dave

My Rocca 90 from Stone Bake Oven co, we built it, using their instructions available on line. Concrete reinforced table slab on steel legs 4 inch thick One layer of Calsil 25mm slabs. Oven base and dome straight on to Calsil. Two layers of thermal blanket over dome. Tin foil, chcicken wire to hold tin foil. Then a lime based render about 30 mm thick. Oak around front with Stainless plate to slide pans over. Stainless steel flue through Lean to green house roof ( mine is indoors) See ukwoodfiredovenforum.proboards.com/thread/1519/bonjour-guernsey for photos I would be tempted to put another layer of calsil slabs under oven and at least another layer of blanket. It holds the heat very well under the base after two days with a fire it is warm to touch, over the dome is warm to touch like a warm radiator, son drys his wetsuit on it after surfing.
