TietexTru™ polyester is one of the strongest materials available as reinforcement in cold process roofing. It offers an unusual combination of high strength properties, delivering good elongation for excellent thermal stress force accommodations. We also manufacture various polyester substrates for in-line roof coating technology. These substrates have tremendous strength properties in machine direction that keeps fabric from necking-in during the coating process. In over 25 years of serving the roofing industry, we know our products are integral to a high quality and complex installation – confirming why we’re serious about ISO 9001 Certification and consistent ASTM testing.
