Sash Windows

Dale Windows


Our modern sash windows faithfully emulate the lines of originals commonly found in Georgian and Victorian homes, but bring 21st century standards and warmth, weathering and performance. We also offer a modern alternative spring system which is uniquely concealed. Careful attention to draught stripping eliminates rattles and draughts, whilst energy efficient glazing maximises solar gain and locks in heat. Sashes may be hung on traditional weights and sash cords or alternatively on neatly concealed springs. A unique easy clean system is available as an option on our traditional sash boxes, which allows the bottom sash to be tilted into the room for maintenance. Our system allows great dimensional flexibility allowing you to tailor your sash windows to the precise requirements of your project. Slim glazing bars in a wide variety of configurations may be added as required.
