Basement Sills (Band Joists)

An uninsulated band joist can account for a significant portion of a home’s heat loss, as the only thing separating inside from outside is two inches of wood and the siding material covering it. If the basement is heated or contains heating or water heating equipment, the loss through an uninsulated band joist is even greater. In most cases, the cost of insulating a band joist is minimal.

The primary factors affecting the potential savings are the average temperature in the basement and the typical freezing winter outdoor temperatures. Insulating band joist areas with spray foam insulation will pay for itself within a few years or less. Another advantage to sealing the area with spray foam is that it helps eliminate access for bugs and rodents.
