Default Re: Dimensions summed up. Are these correct?

mklingles, in his detailed thermal analysis reported:

I have not been able to find a reliable source of data on the amount of energy absorbed by fire brick vs the amount reflected. I believe from the numbers I have found that ~80%of the energy is absorbed and only 20% reflected.
It is this 80% of stored heat that allows a WFO floor to rebound in the cooking of multiple pizzas. It this this 80% of stored heat in the dome that provides the continuous radiation that makes for the wonderful golden-topped artisan hearth bread. Without proper insulation under the floor this stored heat would be leaked into the support slab upon firing and never allow the floor get to proper cooking temperatures. That is the point of insulating under the floor and a mighty big one.
Further, the way I understand it, the thicker one's floor, and the more heat storage capacity, the more floor insulation you need.
