Crystal window offerings

Crystal Window & Door Systems is upgrading the standard window offerings for all eight of its vinyl product lines to Energy Star compliance. By making features such as soft coat low-E glass and argon gas filling standard across the vinyl product lines, all of the company’s most popular basic window models now achieve or exceed Energy Star thermal performance levels in all national climate zones. Depending on the model, options such as triple glazing, foam-filled frames, krypton/argon blends and the Performa TC special three surface low-E glass coating system are available, delivering energy efficiency beyond Energy Star levels.
