Rigid urethane foam is key to lightweight building arch
Design and manufacture of building arch 3 ft wide, 8.5 ft high and 22 ft span made of 3.7 lb/cu ft density rigid polyurethane foam and facing of 32-mil aluminum sheet; at each of two corners formed by juncture of roof and wall sections, plywood compression member is embedded to prevent localized crushing of foam; to make arch, plywood form was lined with aluminum sheet and polyurethane compound was foamed-in-place between sheets; advantages of new structure and its application.
