Basement Slab Insulation Edge
Along with a sloping grade and waterproofed foundation walls, the foundation slabs need to be properly insulated in order to protect the foundation.
Poorly insulated foundation slabs can present several problems involving:
- Energy loss
- Moisture control
- Indoor air quality
Properly install rigid insulation that extends to the top of the slab in either a monolithic slab with a grade beam or a slab independent of the foundation design.
- Make sure the insulation is approved for below-grade use
- Review the plan for slab insulation with pest control and local building officials to achieve compliance
- Confirm that insulation levels meet or exceed state and IECC requirements
