Figure 3-15 illustrates a poured concrete crawl space with Exterior rigid insulation. The rigid insulation aligns with rigid foam sheathing over the 2 x 4 wood frame wall above grade. Rim joist insulation is provided by the exterior foam sheathing, and additional rigid insulation on the inside of the rim. The crawlspace floor consists of a thin “rat slab” cast over perimeter rigid insulation.
