JELD-WEN Premium Atlantic Single Hung Aluminum Window, 53-1/8 in. x 50-5/8 in., White, with Insulated Low-E Glass and Grid 411007

JELD-WEN Premium Atlantic JELD-WEN Aluminum windows provide the reliability you are looking. Our aluminum windows include a unique performance feature - it's our patented silicone-injected corner key, which is created by injecting silicone into the corners for added strength. This feature also ensures the window is reliably weathertight. A single-hung window has a stationary top lite and a bottom sash that slides vertically. The removable side-load sash makes cleaning easy. Standard high-performance Low-E insulating glass lowers energy costs, helps homes stay cooler in the summer and warmer in the winter. For extra charm and architectural interest choose one of our divided lite options.
