Slab Foundation Insulation
I will be building a home in North Central Texas. I was wondering if it is reasonable to insulate with foam board on top of a slab foundation and of course below the flooring used. I have seen foam board used below a slab but not on top. My thinking is there is energy loss due to the HVAC system constantly having to heat and or cool the slab that pulls ground temp into the home relative to the season. Also the heating and cooling of the slab from the exterior of the slab pulls the ambient temp from outside.
