Sash windows are a timeless architectural element that enhances the beauty and character of any home. These windows have been used for centuries and are still in demand today. Sash windows consist of two or more frames that slide up and down to open and close the window. They are held in place by thin timber cords that run through the frames and attach to weights that are hidden behind the frame. While sash windows are beautiful, they can be difficult to maintain if they become damaged, as most homes cannot replace them entirely.
