Constructed with Brilliance, our stunning and highly durable solid white vinyl, this window will never peel, warp, blister or flake. Featuring low-e and Argon gas filled double pane glass, it offers increased efficiency. The fully welded frame and sashes allow for effortless operation, with both top and bottom sashes opening for ventilation and tilting in for easy cleaning. The exterior and interior are both crafted with Brilliance white vinyl, while the corrosion resistant, Teflon-coated, stainless steel constant force balance system ensures smooth functioning. A weather-tight true sloped sill effectively repels water and the Nite locks provide added security, preventing windows from being opened more than 2 inches. The included full screen, made of dark fiberglass mesh, offers ventilation and maximizes visibility while keeping insects out.
