Reviews the use of spray-polyurethane-foam insulation in buildings and discusses how their characteristics influence their field performance. Recommends that when used as an air barrier, polyurethane foam may crack on joints subjected to shrinkage or by structural deflection. To maintain the integrity of the air barrier, one should attach a strip of peel-and-stick membrane to both sides of the joint.
