What Is Spray Foam Insulation Made Of?

Spray Foam is an organic material developed from products of the petrochemical industry. It is a two component system that is sprayed like paint. The chemical constituents are similar to those used in the manufacturer of many products already in your home, such as upholstery foam and the foam used for pillows and mattresses---although the properties of the foam are different.  Spray Foam is an environmentally friendly urethane in which the ozone-robbing CFC's have been replaced with air and water.
