Product review: Spray Foam Insulation

Among the best products on today’s market for energy-conscious homeowners is spray-foam insulation. Because of its abilities to resist heat loss and prevent airflow, it is an investment that will return its value many times over throughout the life of a home.

Open-cell foam is sprayed in place, combining an oil-based component with an adhesive resin to form a semi-rigid, low-density polyurethane foam plastic. In seconds, the foam expands to more than one hundred times its original volume in building cavities to form an air-tight, noise resistant building envelope that is extremely energy efficient.

When used in conjunction with effective building planning, the spray foam system offers numerous advantages to the homeowner. Because of its resistance to heat flow in and out of the house, its cost will be offset by energy savings early in the life of the home, but that is not all. By reducing noise transmission, spray-foam insulation is shown to make rooms 75% quieter than typical construction with fiberglass insulation.

Its air-sealing qualities offer homeowners a healthier place to live as well. Since the 1990’s, the EPA has recognized poor indoor air quality as a serious threat to public health, costing Americans over $1 billion annually in health care costs. No infiltration of outside air into homes means that homeowners do not have to battle pollen, dust and dirt indoors, and that heating and air systems do not have to work as hard to keep indoor air clean, healthy and comfortable.

Sealing out pollutants, allergens and odors is the first step to creating a healthy indoor environment.
