Grace Ice & Water Shield® self-adhered roofing underlayment is a premier membrane composed of two waterproofing materials-an aggressive rubberized asphalt adhesive backed by a layer of slip-resistant coated high density cross laminated polyethylene film. The rubberized asphalt surface is backed with a foldless release paper that protects its adhesive quality. During application, the release paper is easily removed, allowing the rubberized asphalt to bond tightly to the roof deck. The Ripcord® embedded in the adhesive provides the applicator a split release on demand feature.
Grace Ice & Water Shield® is a versatile underlayment material that may be used on sloped roofs, under mechanically attached roof coverings such as asphalt shingles, slate, tile, cedar, and standing seam metal in many climate and assembly conditions.
