Spray Foam Insulation Technology specializes in providing energy efficiency through proper insulation. In the past homes were built to breathe for fear of trapping moisture which would cause future problems. Unfortunately the old ways didn't stop the pollutants and allergens from entering and the conditioned air from leaving thus costing the consumer.
If you are having or want to prevent moisture or insulation problems Spray Foam is the way to go. It is an insulation that is applied as a liquid and then expands forming the foam.
