Sol-R-Skin Blue from Westlake Royal Roofing is a UV-resistant, anti-glare coated roofing underlayment. According to the manufacturer, the product combines an aluminum radiant barrier surface with a fire-resistant mat that provides a Class-A fire rating under stone-coated steel and tile roofing. The blue coating on the underlayment helps reduce glare, making it easier to install than other radiant barrier underlayments. Offered in 54-inch-by-100-foot rolls with a thickness of 3/8 inch, the underlayment can be quickly nailed into place, with an adhesive strip at the head lap. westlakeroyalroofing.com
