Sliding windows are an excellent choice for rooms facing walkways, porches or patios. Made from a variety of high-quality materials including vinyl, wood, aluminum, and fiberglass, these minimal-effort windows are sleek and they open and close without protruding. Sliding glass windows open easier and faster than crank-style windows and are a very popular choice for contemporary-styled homes. Whether they are to be used as new windows or as replacement windows, US Window & Door is proud to offer Milgard’s beautiful horizontal and vertical sliding windows.
