5. Grace Waterproofing Systems Grace Ice amp Water Shield Self adhered underlayment for premium protection Grace Ice amp Water Shield has been the premier self adhesive underlayment product used in domestic roof protection under shingles for more than 30 years It has performed in the critical areas under the most severe climatic conditions to protect against wind driven rain and the effects of ice dam build up beneath the shingles Because of the unique properties of Grace Ice amp Water Shield these benefits are also applicable in its use under a wide range of metal roofing materials on low and high slope designs Advantages Easy to handle and apply Foldless release paper e Seals around nails Dual barrier protection Membrane will not crack dry out or rot e Protects under all standard sloped roof coverings Slip resistant surface Proven track record e Reroofable e Grace technical support Product Description Grace Ice amp Water Shield membrane is composed of two waterproofing materials an aggressive rubberised asphalt adhesive backed by a layer of high density cross laminated polyethylene The rubberised asphalt surface is backed with a release paper that protects the adhesive quality During application the release paper is removed allowing the compound to bond tightly to the plywood deck The membrane is supplied in 20 metre rolls 1 metre in width Features amp Benefits
