What is a conditioned crawl space?

Basically a conditioned crawl is a mini-basement. When you go into a conditioned crawl you will see:

  • A vapor barrier covering the entire floor and going up the walls at least 6 inches. The seams are sealed and it keeps water vapor in the ground from going into the crawl space and then into the house.
  • There are no vents.
  • The foundation walls and band joists are insulated. The only space not insulated is a termite strip so the pest inspector can check for termites.
  • There is a small amount of HVAC supply air going into the crawl space.
