NEW WORLD™ FIBERFRAME™ WINDOWS

Energy Efficiency That Lasts, Strength and Beauty That Endures

Geese instinctively know when it is time to find a better climate. As winter winds blow or as summer heat invades your home, you too look for comfort from searing heat or winter cold. Unlike geese, you don't have to fly south to find it. You can stay right at home and make a big difference in the energy efficiency of your home with NEW WORLD FIBERFRAME Windows.

NEW WORLD Windows have changed a lot of homes for the better over the last decade. Better in energy efficiency, reduced maintenance, beauty and durability. NEW WORLD FIBERFRAME Windows are the original PULTRUDED FIBERGLASS windows from COMFORT LINE. They began as the first of the windows that followed the development of the COMFORT LINE fiberglass patio door that won awards throughout the fenestration industry. That door is now the glamorous and even more rewarding FUTURA PATIO DOOR. NEW WORLD Windows were the windows chosen by technical scholars at the University of Virginia School of Architecture and School of Applied Sciences for the University's entry in a recent Solar Decathlon sponsored by the Department of Energy. With argon or krypton gas added to Low-E insulated glass, all NEW WORLD Windows meet or exceed ENERGY STAR® specifications.
