In 1978, GAF-Elk began production of fiberglass nonwovens in our Ennis, Texas facility. While Ultra-Mat® was originally developed specifically for the roofing industry, GAF-Elk has expanded its capabilities and capacity. Included are sales to other shingle manufacturers and development and sales of both fiberglass and polyester mat for a variety of non-roofing markets. In 1987, GAF-Elk formed the Nonwoven Materials Group to further expand and diversify GAF-Elk's market presence and product capability. Today, GAF-Elk enjoys a solid presence and leadership position in the development and production of both polyester nonwoven products and wet-laid industrial fiberglass.
