Composite systems contain fibers and resins blended together to form a new material.
The pultrusion manufacturing process consists of pulling glass filaments and fiberglass matting through a liquid polyester resin bath, shaping, heating, dying and cutting to precise dimensions. The goal is increased performance, both strength and durability. As a new window and door component, Ultrex was tested in compliance with other window performance standards. In fact, the Integrity products have been subjected to extensive air infiltration, water infiltration, physical load, and design pressures tests. In addition, specifications for fiberglass reinforced thermoset profiles were developed for the American Architectural Manufacturers Association, an ongoing process involving manufacturers and code officials.
