Flush sash windows from Britannic Installations


Perfect for areas of conservation, the flush sash window from Britannic Installations, available in in Sevenoaks, Tunbridge Wells or Tonbridge.


Our Flush sash window from Residence 9® is a new window system designed to replicate the 19th Century Flush Sash Timber Window. It can be considered for use in Conservation Areas due to its authentic appearance. This authentic design is also appealing for any property that is crying out for a top end luxury window brand.


Village Life windows


Residence 9® is designed to replicate the flush sash designs found in cottage properties in our villages. It enables you to replace your window with an authentic design and in authentic colours, without losing the character appearance and feel of the period. Crucially, you can now achieve this in a virtually maintenance free composite material.



Authentic Butt Hinge


With your Residence 9® window, you can specify traditional Butt Hinges to maintain original features. Modern windows often lack this character as the hinges are hidden. The authentic ironmongery is crucial to maintaining an authentic kerbside appearance.




You can personalise your Residence 9® windows with a choice of handles. The Monkey tail and Peardrop designs were popular designs of the period. If your room is more contemporary you can also specify more modern finishes like Chrome, Brass or a Gorgeous Pewter Patina.




Old timber windows often had a raised moulding that ran horizontally across the transom. This bar looked distinctive and gave the window depth and character. Its function was to shed dripping water and to increase the strength. That’s why we recreated the feature with Residence 9®.
