I am in the planning stages of a new house. The house will be 48 feet wide by 48 feet long 2 story for a total of 4,600 sq ft of HVAC Space. Location South Carolina. The house is going to have spray foam insulation with a non-vented attic and crawl space. The foam insulation will seal the attic, all walls, and the crawl space. The bottom story floor will not be insulated as the crawl space will be conditioned. QUOTE Here is the quote breakdown as written.
