UPC 500 is a two component, water blown (zero ozone-depleting chemicals) light density, open-cell spray polyurethane foam insulation. UPC 500 is designed to improve the performance of the building envelope for commercial, residential and industrial applications. When properly installed UPC 500 expands, sealing voids, gaps and crevices. Ideal fit to help fill cavities of any shape, providing an air barrier to reduce air leakage, and a higher Rvalue than other insulating materials, resulting in increased energy savings and comfort.
