Grace Ice and Water Shield® - Self-Adhesive Roofing Underlayment

Roofing membrane 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.

Features and benefits:

• Easy to handle and apply- bonds firmly to the roof deck without heat or special adhesives. Watertight laps are easily formed.
• Aesthetically pleasing- unlike other forms of ice dam protection, Grace Ice & Water Shield is concealed by the finished roofing, preserving the architectural appearance of the roof.
• Seals around nails- the rubber bitumen layer seals around roofing nails, resisting leakage caused by water back-up.
• Dual barrier protection- rubber bitumen and polyethylene are combined to form two waterproofing barriers providing maximum protection.
• Membrane will not crack, dry out or rot- resists attacks from fungus and bacteria; maintaining its integrity for long lasting protection.
• Protects under all standard sloped roof coverings- protects under slate, tile, or metal.
• Slip resistant surface- has a slip resistant embossed surface to maximise traction and safety for applicators.
• Proven track record.
