COMPOSITE ROOFING MEMBRANE
A composite roofing membrane is disclosed having upper and lower surfaces. The composite roofing membrane contains, in order, a first membrane, a second membrane, and a nonwoven fleece. The first membrane has a first side and a second side, where the first side of the first membrane forms the upper surface of the composite roofing membrane, and where the first membrane comprises a thermoplastic polymer. The second membrane has a first side and a second side, where the first side of the second membrane is adjacent to and in direct and intimate contact with the second side of the first membrane, and where the second membrane comprises a thermoplastic polymer. There are no fibers or yarns between the first and second membranes. The nonwoven fleece contains a plurality of yarns, has a tensile strength of between 100 and 1000 lbf, and a tear strength of between 20 and 200 lbf.
