Insulating Over Slab
It is important to insulate slabs to reduce the potential for condensation (or sweating) on the slab and to reduce energy loss and increase comfort. And, it is critical to insulate slabs that are going to have floor coverings installed over them to reduce the potential for condensation and mold. It is easy to insulate above new or existing concrete slabs. STYROFOAM™ extruded polystyrene insulation offers high moisture resistance, compressive strength and R-value and is ideal for this application.
There is a STYROFOAM insulation solution for insulating over every slab:
