Is there any way to eliminate perimeter slab insulation completely?
Perimeter slab insulation can be “traded-off” using a software tool like REScheck or COMcheckâ˘. Additional insulation is added in another part of the structure to compensate for the missing insulation in the slab. The code permits this trade-off, but when carpet is placed on a cold slab, the higher humidity levels that result can attract dust mites and mold.
