Abstract: High-strength built-up roofing (BUR) membranes and systems are provided herein. These BUR products are made using improved glass fiber mat structures having unusual tear resistance in place of organic felts.The glass fiber mats are constructed from two fibrous components, namely, individual filaments, which provide the uniform denseness required for impregnation of saturant asphalt in the interstices of the mat, and extended fiber elements formed by longitudinal extension and connection of fibers from bundles of glass fibers in a wet-laid process, which furnish tear resistance and tensile strength to the BUR membranes and systems.The BUR membranes and systems of this invention have exceedingly high strengths compared with commercially available products of similar construction, and, advantageously, they can be manufactured by a very economical process.
