Description

Grace Ice and Water Shield® is a self-adhesive roofing underlay for roof leak protection or sloping timber roofs. The membrane is composed of two waterproofing materials - an aggressive rubber bitumen adhesive backed by a layer of cross laminated HDPE. The rubber bitumen surface is backed with a release paper that protects its adhesive quality.

The underlay must be fully supported by the substrate. Suitable substrates include plywood, wood composition, wood plank, metal, concrete, or gypsum sheathing.
