Does polyurethane technology control air leakage?

Our polyurethane foam wall systems have been tested and are certified to be an air barrier at an application of 1-inch thickness. Once applied, our wall systems are fully-adhered and do not allow air to flow around, behind or through the insulation system. Most open-cell foams have not been tested and therefore do not qualify as air barrier systems. One open-cell foam manufacturer’s product requires an application of 5.5 inches to pass the minimum requirements of the air barrier test. The U.S. Department of Energy (DOE) has shown that 15 percent of traditional insulation materials’ effectiveness is lost due to convection loops through and behind board and batt systems. Spray-applied polyurethane technology eliminates this by forming a fully adhered, seamless insulation and air barrier system. Can an insulation system add structural strength? Spray-applied closed-cell polyurethane foam is the only insulation material that adds structural integrity throughout the wall system. Testing ...  more
