When your property sits in an area of conservation, is more traditional in its style, or you’d like it to look that way – uPVC sash windows are an excellent alternative to timber. While in the past, Timber has been the only window to give an authentic look, that’s no longer the case. Upgrade to modern security, draft control and authentic styling today. 

Design your own window, or get in contact with your requirements. We supply and instal in and around London. We look forward to hearing from you.
