Owens Corning has used its patented Advantex E-CR glass fiber to develop the OC HiLight. The multi-end roving has a patented sizing that offers high transparency. It is ideal for use in greenhouses, cladding, skylights and other architectural purposes. The finished laminates contain higher proportion of glass fiber and thus exhibit better mechanical properties, including stiffness and robustness. Higher glass content reduces the amount of resin required in a thinner panel and thus decreases production costs.
