Abstract
An enhanced performance roofing membrane, having: (a) a bottom membrane layer; (b) a top membrane layer; (c) a scrim layer between the top and bottom membrane layers; and (d) a reduced density membrane layer between the top and bottom membrane layers. The reduced density membrane layer may be a foamed layer, or a layer of polymer with gas pockets or beads therein. The reduced density layer may be made of the same materials as the top and bottom layers.
