Spray Polyurethane Foam insulation has become an important building material that enables the design and construction of buildings with ultra-high energy efficiency. The high insulation values keep occupants comfortable with minimal energy costs, and the air and vapor barrier properties sustain healthy indoor air quality by preventing the intrusion of pollution and allergens. SPF is ideal for resilient design practices in areas where flooding and hurricanes are common. New SPF products are formulated with next-generation blowing agents with ultra-low global warming potential and zero ozone depletion potential (ODP).
