Non-Woven Fabric

DESCRIPTION
American WeatherStar Non-Woven Fabric (AWS NW) spunlaced fabric is a textile material composed of staple fibers hydraulically entangled to form a strong reinforcing membrane for cold roofing mastics. Composed of 100% polyester, AWS NW has excellent conformability and elongation. The open aperture design allows mastics to flow through and form saturated rather than a laminated roofing membrane.

AWS NW is light weight with high tensile strength and toughness. It is nonraveling, has excellent tear strength and is resistant to chemicals and solvents, and is nonirritating to skin.

AWS NW spunlaced fabric maintains its physical properties when wet and is dimensionally stable during humidity changes. Expansion and contraction of building materials due to temperature changes make it necessary to have a roof surface that allows for this movement, AWS NW has the elongation properties to do this.

AWS NW has been successfully used with a variety of cold process roof coatings, including cutback asphalt, asphalt emulsion, elastomeric asphalt and acrylic coatings. Embed the fabric with a coating and cover as per coating manufacturer's directions.

RECOMMENDED USES
• Metal Building Seams
• Pipe Wrap 		• Commercial Roofing
• Cant Strips		 • Roof Repair
