Both types of foam are commonly used in most building applications, and the choice for which to use can depend on many of the factors discussed above. Some foams are inappropriate in specific applications. For example, you typically would not use open-cell foam below grade or in flotation applications where it could absorb water; this would negate its thermal performance because water is a poor insulator compared to air. Closed-cell foam would be a good choice where small framing sizes need the greatest R-value per inch possible. Closed-cell foam would be used for roofing applications.

As energy prices continue to soar, those kinds of savings are particularly attractive to new homeowners. "Builders need to stay competitive. One of the ways they do so is by offering their homeowners top-quality, energy-efficient products," Nick says. "Foam is therefore becoming a must have in custom building." But the benefits are not only for new construction. "The insulation in homes built before 1995 has an 85% chance of being under insulated," Nick explains. "Plus, the industry's' minimum-required R-values have changed dramatically in the past 10 years."
SPF can also add structural strength to buildings. NAHB Research demonstrated SPF-filled walls could add from 75 percent to 200 percent racking strength to walls of OSB, plywood, light-gauge metal, vinyl siding or gypsum board.
Residential Roof Repair
The polyurethane foam dries within seconds after application to the roof surface. Its expansion results in a weather-tight roofing membrane that is fully adhered to the substrate. Because of polyurethane's lightweight nature, it adds little additional weight to the structure and is often used in remedial applications.
Residential Roof Replacement/Installation
Polyurethane foam has a history of more than 35 years as a maintainable roofing medium. Polyurethane foam adds excellent insulation value to the structure, and utility bills can reflect the difference.
