Product details:

Rubberized asphalt layer seals around fasteners - resisting leakage caused by water back-up behind ice dams, or from wind-driven rain. Superior Adhesion to the Deck — The self-adhesive membrane bonds firmly to the roof deck without the need for heat or special adhesives. The Ripcord Split Release on-demand feature makes Grace Ice & Water underlayment easier to apply. Slip-resistant surface — Grace Ice & Water self-adhered membrane has a slip-resistant embossed surface to maximize traction and safety for applicators. Up to 120 days UV exposure, Roll Thickness: 40 mils, Tensile Strength: 250 psi The Grace Ice & Water Shield is a self-adhered underlayment composed of aggressive, rubberized asphalt adhesive that is backed by a layer of cross-laminated, slip-resistant coated, high-density, polyethylene film. A foldless release paperbacks the rubberized asphalt surface and protects its adhesive element. The foldless release paper is simple to remove during the application which allows for the rubberized asphalt to bond tightly to the roof deck. The split release on-demand component is created through having Ripcord embedded in the adhesive.
