Insulating a Weems, VA Crawl Space with Foam Board

Moving the crawl space insulation from between the floor joists to the foundation walls extends the thermal boundary of the home to the floor of the crawl space. Along with insulating the rim and band, this helps to reduce drafts and cold floors. 

Foam Board is installed by mechanically attaching it to the foundation walls leaving a viewing strip at the top of the foundation wall per building code for termite inspections. All seams of the foam board are sealed to create an air barrier.
