Combining a standard granulated cap sheet with a highly reflective roofing surface, Cool Roof Granulated (CR G) cap sheet is the company’s most cost effective cool roof option for modified bitumen. The cap sheets’ granules mitigate solar heat to provide interior comfort and mitigate the urban heat island effect. In addition to the membranes, five-gallon containers of the granules are available as well for dressing up bleed-out at seams. The product has UL approvals and is listed with the Cool Roof Rating Council.
