PolyBrite Reinforcing Polyester is stitch bond, light weight, high performance polyester fabric used in the reinforcement of cold process roofing systems and also as a reinforcement with mastics and elastomerics. The flexible nature of this fabric also allows for ease of application over the critical corrugations and laps found in metal roofing and conforms with smooth and semi-smooth surfaces. This product may require light brooming to insure good embedment and removal of any air pockets.
