The image above shows a timber bay window that we manufactured and fitted for a customer in North Yorkshire. The bay contains six double-glazed sashes. We receive lots of enquiries regarding our sash-window, double-glazing upgrades during the colder months. You can keep the traditional look of your home and improve its thermal efficiency by upgrading your windows. Fitting energy efficient double-glazed units is a recognised means of reducing energy bills and external noise. We use Accoya® timber when manufacturing wooden windows because of its guaranteed longevity and green credentials. You can learn more about Accoya® by watching the short video on our website.
