The Rehau heritage vertical sliding sash window system is designed to include the traditional features of a timber sash window, yet with all the advantages and convenience of modern UPVC.

The double-glazed sealed units considerably reduce outdoor noise levels, allowing you to relax in the peace and quiet of your home. The superb period look is backed up by a very modern approach to security. The three-chamber sash profiles allow for even stronger reinforcement and require low maintenance. Unlike traditional sash windows, a modern sash window can be energy efficient and conform to Document L of building regulations.
