Abstract
The use of spary in place polyurethane foam for roofing application in the United States is increasing at a rapid rate. Little unbiased information is available to guide the user in the specification, selection, application and performance of this innovative roofing system. This report describes the current state of the art of rigid polyurethane technology as applied to a roofing system. The performance parameters as observed during the field surveys are discussed in terms of protective coatings, fire safety, durability and problem areas. Guidelines to assist the supplier and user alike in the use and selection of polyurethane foam roofing systems are given. Finally, a performance specification for spray-in-place polyurethane foam roofing system is suggested.
