Benenden Slim Line Windows

Meet The Benenden

Our official Benenden Conservation™ slimline window range, the Benenden has been designed to offer aesthetic homage to traditional steel windows and acts as a direct upgrade for period properties that seek modern performance and combines the advantages of aluminium windows with the style of period frames.

Featuring an ultra-slim profile of just 39mm for maximum sightlines, the Benenden Conservation™ windows boast a Window Energy Rating of B and combine stunning traditional aesthetics with modern functionality. These aluminium windows conform to both replacement and new-build regulations and are PAS24 rated with a modern multipoint locking system for added security and the Benenden range can be installed into existing subframes, direct to brick or stone.

Every property’s design is unique, which is why the Benenden Conservation™ windows are available in dual colour options for different internal and external colours on the frame. Choose from any RAL colour for your windows, with windows arriving in black and white as standard. Dummy Projection or Barrel hinges are also available to preserve original aesthetics and functionality on heritage buildings, with a range of handles such as Heritage Traditional or Monkey Tail as well as matching peg stays available.
