Need to apply a heat gain calculation. I have a diamond plate metal floor which stretches from one chamber to the next. In chamber A, the temperature is 80 degrees. In chamber B, the temperature is 40 degrees. The 2 chambers are separated by a curtain which helps to minimize convection / air infiltration. Need to understand the benefits in heat minimization from a thermal barrier. The floor is 1/8" diamond aluminum plate. The width of the door frame is 30". The warmer chamber B is 4' by 4' and is constantly at 80 degrees. The cooler chamber A is 6' by 4' and is kept at 40 degrees. A simple Fourier equation would show 1,810 BTU's.


q = k A dT / s
145 BTU / (hr x deg F x ft^2 / ft) x ..026 ft^2 x (80 deg F 40 deg F) / .0833 ft
145 x .026 x 40 / .0833 = 1,810

This ignores the gradient nature of heat transfer (is wrong).

I do not want a massive computer model, just a simple integral or suggestion on approach in exchange for 1 hour of work and strong ratings....
