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 UPVC without the problems associated with timber sash windows. Our Quality sash windows feature tilting upper and lower sashes for ease of cleaning, low-line beads and glazing gaskets for improved sight lines and energy efficient glass for enhanced thermal performance. From terraced housing to stately homes, 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, whilst providing the benefits of modern-day technology. Many buildings have been disfigured by inappropriate window replacements that have not maintained the original design aesthetics of the property. Once installed, new sash windows blend into their surroundings. 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 sash windows. 

Built to Last 

Our Sash Windows are fully reinforced with aluminium and sliding sashes are reinforced with galvanised steel to resist deflection under extreme wind loading conditions and carry the weight of the glass. In addition to strengthening the sashes, the galvanised steel reinforcement provides a strong, secure fixing for lifting handles, latches and other components. High quality balances maintain the equilibrium of the sash window at any point of travel and robust locking devices ensures your homes secure. Operating hardware is designed to give improved levels of strength and durability, safety and comfort to ensure that once installed in your home these windows are built to last.
