A granulated, fiberglass-reinforced, SBS-modified-bitumen self-adhered peel-and-stick roofing underlayment, 55 mils thick, built to replace traditional asphalt-based sanded and granular peel-and-stick underlayments. A 3-inch overlap edge and split silicone release liner aid installation, and the spec sheet reports thermal stability to 250 degrees F and a 90-day UV/water exposure limit.
