Wall Insulation (Cumulative R-19)
All heated and cooled areas are insulated from unconditioned areas
OSB corners and/or metal bracing are used in conjunction with foam sheathing to provide added comfort and stability.

Insulated Crawlspace
A minimum R-10 perimeter wall insulation and 6-mil polyethylene vapor barrier over pea gravel features overlapping joints and 100% coverage.

Notice: Vents are omitted so as to avoid moisture build-up caused by the mixing of summer time warm-humid air with cool-conditioned crawlspace air.

Attic Insulation (Minimum R-42)
If attic is not a living space, the ceiling shall be insulated because it's the barrier between the conditioned and the unconditioned space. Blown insulation, foam or fiberglass batts shall be used for attic insulation.
