Cofair’s Stormblock Wind & Water Guard is a self-adhering waterproofing underlayment membrane designed for extreme applications. It is composed of a tough multi-layer high-strength polymer film coated with a layer of specially formulated rubberized asphalt adhesive. A release sheet protects the asphalt and is removed as the membrane is installed.

To improve surface traction, a raised pattern has been embedded into the top of the polymer film.

Stormblock Wind & Water Guard underlayment is engineered to be suitable for use under all roofing materials. The rubberized asphalt adhesive and the reinforced polymer film are formulated to work in higher temperature applications such as under metal roofing. Stormblock Wind & Water Guard adheres aggressively to most clean, dry substrates including metal, wood, oriented strand board, foam board, vinyl and masonry.

The special Stormblock Wind & Water Guard polymer modified waterproofing compound self-seals around punctures such as nails, screws and staples. This advanced system will bond to the substrate and will seal around fasteners to prevent damage caused by water penetration.

INTENDED USES
Underlayment for shingle, clay tile, cement, synthetic, shake, and metal roofing.
May also be used to waterproof under stucco at head, sill, chimney shoulder,
