What is Spray Foam?

Also known as spray polyurethane foam or SPF, spray foam insulation is applied as a liquid. It expands upon contact with your building materials instantly to create an air and moisture barrier. It is used frequently in attics and in walls. It's a perfect choice for hard-to-reach or inaccessible areas, as it can be sprayed in using equipment, rather than laid with hands. SPF is very effective in reducing the passage of air (and pollen and pollutants) through cracks and seams in your attic or siding. It has fast become the insulation material of choice for builders.
