June 13, 2011 Spray Foam Spray foam insulation is becoming a standard in insulation as a direct result from the rising cost of energy. When spray foam insulation is applied, it expands to fill and seal each cavity from air infiltration. This reduces the amount of heating and cooling you need which translates to huge savings on energy bills. Another benefit spray foam insulation provides is blocking air pollution and mold spores, creating a cleaner, more comfortable indoor environment for you and your family.
