Details

GCP Applied Technologies (Formerly Grace) Ice & Water Shield is a proprietary and time-tested rubberized asphalt formulation that enables a watertight bond with the roof deck acting as a barrier for both water and ice. 

 

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 (see limitations for additional information).

Grace Ice & Water Shield® is supplied in 3 ft wide rolls of varying lengths. Membrane strips are also available in 75 ft (22.9 m) long rolls at widths of 6 in. (150 mm), 9 in. (225 mm), 12 in. (300 mm) and 18 in. (450 mm). See the Product Data chart for product information. 

Features & Benefits

  • Seals around fasteners - seals around fasteners, resisting leakage caused by water back-up behind ice dams, or from winddriven rain.
  • Superior Adhesion to the Deck - The self-adhesive membrane bonds firmly to the roof deck without need for heat or special adhesives.
  • Watertight Laps - Membrane easily forms water-tight overlaps without special treatment.
  • Protects under all standard sloped roof coverings - protects under slate, tile, cedar shakes or metal, as well as under conventional asphalt shingles.
  • Ripcord - Split Release on demand is easier to apply. Faster application of the membrane in the straight-aways, as well as ease of membrane positioning in detail areas (valleys, around dormers, etc.).
  • Slip resistant surface - has a slip resistant embossed surface to maximize traction and safety for applicators.
  • Reroofable  - Unlike granular surfaced membranes, will not adhere to the underside of the exposed roof covering. Membrane can be applied over the old GCP self-adhered underlayment in retrofit applications, making re-roofing easier, less costly (since there is no need to remove the existing underlayment), more durable and environmentally friendly (as the structural deck remains intact avoiding the need to purchase additional wood decking).
  • Membrane will not crack, dry out or rot - resists attacks from fungus and bacteria; maintains its integrity for long lasting protection.
