Forgent Series windows and doors are comprised of Glastra® – a proprietary hybrid of fiberglass and UV stable polymer, formulated for strength and resilience. An advanced ladder design adds strength, while promoting long-term durability and energy efficiency for comfortable homes. An integral nailing fin and welded sash and frame provide rigidity – keeping units square, and preventing air and water from entering the joint.
