Re: Starting new 36" build
I have a question about insulation between the hearth layer and the cooking floor:
I purchased 2" of FB Board insulation to install under my oven. The spec sheet for the board says that:
I have seen recommendations for 2 layers (4") of the FB board on the board. That seems like total overkill to me - as the goal of the floor insulation should be to reduce the heat transfer to the point where it is equivalent to roughly the temperature of the hearth - about another 100-130 degrees
Beyond that point, you really aren't losing any heat so you are past the point of diminishing marginal returns from insulation
I am trying to figure out if there is a cheaper material I can use at 1" thickness to accomplish that last bit of temperature reduction. Something I can source locally that is more in the $5/sq foot price range than the $12 per sq foot that the FB board costs.
Any suggestions? Would an inch of perlite do the trick?

"One 2" thick layer of FB Board panel reduces the 800?F cooking floor of a pizza oven to roughly 170?F at equilibrium"
