Timber box sash windows

Period charm with modern efficiency

Built with slow grown, knot-free timber, our box sash windows will never twist or warp over time. They’re operated with weights and pulleys, and the windows can be hung using pre-tensioned nylon cords or chains. You’ll remain nice and cosy in winter thanks to our unique and concealed triple weather strips.

We can also provide the slimmest box sash window in the UK, measuring only 142mm from front to back. These are perfect if you’re replacing single-glazed windows, which are slimmer than modern double glazing, allowing us to install without intruding into your room.

They come with a rock-solid 30-year guarantee against rot and fungal decay.

Why choose Burgess Group box sash windows?

  • Every window we install is bespoke, with thoughtful design to enhance the architectural integrity of your home.
  • Our experienced designers, surveyors, administration and installation teams will ensure a seamless experience from entering the showroom to installation
  • Through the IWA we offer our customers an insurance- backed guarantee and deposit indemnity
