    Our economy silver fixings are butt hinges that are suitable for our single styrene glazing option. The opening windows are top hung where they also come with silver casement stays as standard.

  • Premium Fixings

    Our premium brass hinges are more heavy-duty and can easily support the weight of our double glazed windows and doors. They are also supplied with brass casement stays. You can still choose to have our brass fixings with our styrene glazed windows and doors if you are looking for a more premium finish.
