S-RM Series Glass Fiber Felt is a high-performance reinforcement material designed for SBS and APP modified bitumen waterproofing membranes, colored asphalt fiberglass shingles, and thermal insulation systems. With uniform fiber distribution and longitudinal reinforcement, it offers enhanced tensile strength, crack resistance, and durability. Compared to traditional felts, it resists high-temperature flow, low-temperature cracking, and aging, with excellent alkali resistance and impermeability. Given the product’s features and wide use, our company offers the S-RM-M series (glass fiber thin mat composite mesh cloth) and S-RMT series (glass fiber thin mat + PVC coating). These products have strong crack resistance and good corrosion resistance, making them ideal building material bases.
