Roofing Membrane with Nonwoven Backing
A roofing membrane having a first and a second side and comprises a membrane layer and a nonwoven layer. The membrane layer forms the second side of the membrane and the nonwoven layer forms the first side of the membrane. The nonwoven layer has a weight of between about 2.5 and 15.5 ounces per square yard and comprises a plurality of intertangled fibers. At least 60% by number of the intertangled fibers have a length of at least about 3 inches and the intertangled fibers have a round or tri-lobal shape. The intertangled fibers comprise a mixture of a bulking fiber and a core/shell low melt fiber, where the shell of the low melt fiber has a melting temperature between about 50 and 220° C. and the bulking fibers have a melting temperature of at least about of 240° C. The first side of the membrane has a plurality of loop elements.
