Traditional styling

 VS sash windows maintain the elegant proportions of traditional sash windows, whilst incorporating the very best in modern day technology to deliver the low maintenance and high security of PVC-U without the problems associated with timber sash windows.

Quality-assured VS sash windows feature tilting upper and lower sashes for ease of cleaning, low-line beads and glazing gaskets for improved sightlines, and energy efficient glass for enhanced thermal performance. From terraced housing to stately homes, VS sash windows enable old-style properties to retain their heritage, character and charm. A wide range of styles, colours and hardware options can be specified providing the benefits of modern day technology. Sculptured astragal glazing bars, decorative sash horns, two smoothly sliding sashes and a choice of quality operating hardware options all add to the traditional appeal of VS sash windows.
