Polyester fabric is a versatile material used in various roofing applications, primarily as a reinforcement layer. Here's a breakdown of its key features: * Strengthens Roof Systems: Polyester fabric enhances the tensile strength of roofs, particularly around seams, flashings, and other vulnerable areas prone to movement and cracking. * Conforms to Irregular Surfaces: Unlike rigid materials, polyester fabric's flexibility allows it to seamlessly adapt to uneven roof surfaces, ensuring a uniform and effective reinforcement layer. * Compatible with Various Coatings: Polyester fabric can be used with a wide range of roof coatings, including asphalt emulsions, solvent-based cold process systems, and elastomeric coatings. Overall, polyester fabric plays a crucial role in reinforcing roof systems, extending their lifespan and integrity.
