Blenheim

Product Information

Transform any home in an instant with the Blenheim range of sliding sash windows from Benlowe. This particular design encompasses many of the traditional features of previous designs such as the manual weight and pulley system. For modern projects, the Blenheim sliding sash is available with high-quality double-glazing, however, upon request, we can provide single-glazed versions for conservation projects. These period-style windows will bring charm, style and security to a wide range of homes and are made-to-order for added authenticity.
