I could place 2″ XPS vertically against the inside of the foundation stem wall before the slab is poured effectively insulating the slab from the exposed foundation. The majority of heat loss through a slab occurs at the perimeter, as this is the portion most exposed. For slabs that are independent of the foundation, the slab must be thermally isolated from the foundation by installing insulation at the slab edge and under the slab perimeter. Should I insulate around the edges of the basement slab to prevent continuous thermal bridging and heat loss from the heated slab into the foundation wall and eventually down to the footing and into the ground? Kingspan GreenGuard® GG350 Slab Edge Insulation The Kingspan GreenGuard® Insulation Board is made from closed-cell extruded polystyrene, making it ideal for under concrete slabs and along the slab edge. 1 This suggests that insulating slab edges is far more effective for preventing heat loss than insulating the underside of the slab.
