Fabrics

Overview
Architects and engineers have long realized that waterproofing compounds themselves are highly water-repellent, but do not remain in place if applied alone. Reinforcement fabrics add strength and flexibility to the waterproofing agent, and provide the means for specified quantities to be built up in place.

Features
Koppers offers these fabrics for use in roofing:

• Cotton Fabric, black asphalt coated
• Standard Cotton Fabric, black asphalt coated
• Glasfab, black asphalt coated, or coal tar coated by special order
• Glascoat, white or yellow resin coated
• Jute, black asphalt coated
• U.F. Mat, white polymeric coated

Details
Glasfab® and Glascoat® Woven Glass Fabrics are both well-known and widely accepted in the construction industry. Glasfab, an asphalt coated fabric, and Glascoat, a white resin-coated fabric are inorganic woven glass membranes which will not rot, are lightweight and will conform to irregular surfaces. The tensile strength of glass fabrics is greater than cotton fabric or jute.

Koppers Jute (Burlap) Fabric is asphalt saturated. Commonly known as treated burlap, it is a coarse fabric which tends to hold more bituminous roof coating material, resulting in a heavier build-up of coating in fewer applications. It is quite often specified for roofing and waterproofing. Jute is also used for protection of newly seeded areas, embankment erosion control and ditch liners for holding planted materials in place until growth starts.

Koppers Glass Mats are widely used with cold-applied roofing products. They are non-shrinking, possess excellent embedment qualities and are easy to use.

The U.F. Glass Mat is white, lightweight and comprised of fine glass filaments in a random swirl arrangement, reinforced with glass strands at the edges and bonded with polymeric resin.

Benefits
Reinforcement fabrics are necessary for waterproofing and roofing systems to add strength to the waterproofing agents (bitumens) and serve as mechanical reinforcement for hot or cold applied bituminous coatings in roofing and waterproofing systems.

• Koppers fabrics are lightweight and easy to use.
• They are strong, resistant to rot and flexible enough to conform to irregular spaces.
• They provide the durable framework to build up coating thickness, achieving longer lasting waterproofing systems.
• The variety of features offered by Koppers wide range of fabric products, means that we have a fabric to fit your roofing project.
