The newest addition to the GreenScreen family of PVC-free solar-control fabrics, GreenScreen Eco is made of pre-stretched polyester that allows the fabric to maintain stability over large areas. With a 3 percent open weave, the fabric is available in five colors, and can be matched to any color specification. Nysan also offers customized dual coloring, in which each side of the fabric is a different color for a greater level of heat control, glare reduction, and outward visibility.
