Grace Ice and 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 time-tested rubberized asphalt formulation has been proven to form a watertight bond with the roof deck and to seal around fasteners used to attach roof coverings.
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. This split release on demand feature makes installation around difficult areas like chimneys fast and simple.
Grace Ice & Water Shield fully-adhered smooth surface roofing underlayment has been the leader in roof underlayments for over 35 years.
