<p>Roofing membrane comprises reinforcing scrim fabric (12) and a polymeric material. The fabric is preferably a polyester tri-directional laid scrim fabric made from continuous yarns (20), which is held together by an adhesive. The polyester scrim fabric includes a central area (16) and selvage areas (18)on opposing edges thereof. The selvage areas of the fabric include more strands of yarn than the central area, to provide additional strength along the sides of the fabric. Further, the continuous yarns that make up the selvage are not cut along the edges, so that the continuous yarns form loops (22) along the edge portions of the selvage areas.</p> |
