Does using spray foam insulation create big savings on fuel?

It certainly can. There are a number of factors that influence the use of fuel, ranging from building materials to building design to comfort and temperature preferences in the home. Typically, the fuel savings question is in regards to compensating for heat loss and gaps that contribute to air loss of the homes. When comparing use of fuel in accordance to air loss when comparing fiberglass products to spray foam, it has been tested and noted that close-cell spray foam fiberglass insulation offers 25%-40% more ‘R’ and offers significant advantages in gap filling and air loss control. The net gain of a tighter seal and higher ‘R’ value presents the opportunity of less fuel usage, which in turn can save a Maine home with 1,800 square feet around $447/year in fuel costs.
