Based on information from the American Chemistry Council, spray polyurethane is more than just one of the leading insulation materials for your construction projects. It can also serve as a structural strengthening agent in the buildings where it's installed. Closed cell spray polyurethane foam doesn't just hold in heat in winter and air conditioning in summer, it also protects against the damaging forces of wind and moisture.
Unlike other insulation materials for your construction projects, closed cell SPF helps effectively glue roofs to buildings. It helps the roofing materials resist the powerful force of wind uplift that attempts to pull them from the building in severe storms. When applied inside a wall as insulation, it increases the wall's ability to withstand high winds that could otherwise crush it in on itself. This increase in racking strength is unique to closed cell SPF.
While most materials for your construction projects are susceptible to moisture, closed-cell spray polyurethane isn't. Because of its unique structure, it repels wetness and, if it does get damp, it dries back to its original form while maintaining its top-quality performance. Furthermore, it conforms to the surfaces where its applied. This means that it naturally expands to fill cracks, seams, and small open areas around fasteners. With these properties, SPF can block both debris and moisture from entering a building and compromising its integrity.
