One of the biggest benefits of new NatureScape Windows is the increased comfort and energy bill savings you'll enjoy both winter and summer. Quality design and construction put an end to air and water infiltration. You can also choose glass options that offer additional benefits. For instance, double-paned insulated glass offers excellent U-value and reduces sound when compared to ordinary-single paned glass. And our standard insulated glass is covered by a 10-year warranty. NatureScape also offers heat reducing tints and high-performance low-E coatings that reduce solar heat gain while protecting your furnishings, draperies and artwork from fading. They're particularly beneficial for western and southern exposures.
