Insulation & Air Sealing - Insulating a Floor with Spray Foam

The owners of this home wanted their floors to be warmer. The house was built on a 3-ft-high crawl space that was later dug and transformed into a shallow, unconditioned basement. 

The room above this shallow basement was very cold and drafty during the winter time. Dr. Energy Saver concluded that insulating the floor above the basement would be the best approach for this particular home. Thus leaving the basement unconditioned, rather than conditioning the whole space and including it into the internal building envelope. Spray foam was applied between the floor joists. Spray foam insulation expands as it is applied, filling every gap around joints, plumbing, wiring, ducts and fixtures. Spray foam not only insulates but air seals the floor as well.

If your home sits on a vented, unconditioned crawl space or basement, your home is wasting a lot of energy. Cold floors, drafty rooms and high energy bills are some of the symptoms of energy loss through the crawl space and basement.
