few questions

[jodwayne]

Hi I have started my project and have a few questions. Unfortunately i didnt find this thread until after I started my project. My oven is a hobby project that I would like to be able to cook a few pizzas on when we have guests. No need for 20 pies an hour or anything like that. I have made my structural base and after pricing calsil board am ready for the vermicrete insulation that supports the hearth. My questions are 1. will the vermicrete support the whole oven or should the hearth bricks be on the vermicrete and the walls built on the concrete base. It seems better insulated without direct contact of the walls and the base. 2. is the vermicrete weather proof I am concerned about keeping rain and moisture away from this insulation layer. My oven is in the woods at our farm and we get some pretty raw weather here especially in winter lots of freeze thaw cycles. Thanks in advance love the forum.
