Stunning Sliding Sash Windows 

At JKG Windows & Doors, we're proud to offer premium sliding sash windows that seamlessly blend classic aesthetics with modern performance. Our windows deliver the perfect combination of style, energy efficiency and versatility for your home.


Traditional timber sash windows have graced British homes for centuries, and our modern uPVC or timber versions maintain that timeless charm. Our vertical sliders feature smooth operation with a balanced load mechanism, allowing both the top sash and bottom sashes to move effortlessly. The deep bottom rail and optional authentic woodgrain finish create the appearance of a historic timber window, making them perfect for both period properties and conservation areas.
