Closed-Cell Spray Polyurethane Foam Insulation: A Preferred Air Barrier System in Building Envelopes

Expectations for better building performance underscore the importance of air barriers for commercial-building envelopes and code compliance. Use of closed-cell spray polyurethane foam (ccSPF) as a key material in air barrier assemblies can help architects, engineers, contractors and owners/developers meet air barrier requirements more easily. CcSPF provides excellent performance characteristics and construction advantages.
