Summary: Rigid foam insulation or foam board insulation provides energy efficiency and moisture resistance.
Homes should be comfortable and energy efficient.
Warmer exterior walls, roofs and floors, including basement foundation walls and floors, can add both comfort and energy efficiency.
A good way to achieve warmer walls, roofs, and floors is with rigid foam insulation, also called insulated foam sheathing as well as foam board insulation.
Rigid foam insulation can be used both above ground and below ground to insulate basement walls and to insulate basement floors, as well as to insulate concrete slabs when you build a concrete slab foundation.
