Box Sash/Authentic UPVc Sash Windows By Osborn Glass

Our authentic UPVc vertical sliding box sash windows imitate 17th century windows perfectly and are ideal for older traditional properties or in areas of conservation. They are designed to offer modern solutions without compromising on the traditional look and feel of the sash window. Listed and conservation areas can be found in London, Surrey, Kent and Sussex, some of which have approved the installation of UPVc. Our sash windows are available in UPVc, timber, and aluminium profiles, each one sourced from the best UK manufacturers and complement a variety of other products that we offer.
