Skilled craftsmen with high-tech solutions
There are two main elements to a sliding sash window: The box, which is fitted into the walls; and the sashes, which are the two glazed frames that move up and down. In most cases, we can fit top of the range double glazed units into your original box sash. This saves a great deal of work and disruption in two respects: we don’t have to manufacture new boxes; and we don’t have to disturb plaster work by installing new boxes. The window boxes need to be timber and in good or repairable condition in order for us to complete this work.
We install slim glazing units. This enables us to manufacture sliding sashes using traditional methods, including solid glazing bars (instead of ones attached to the glass) which help to retain the window’s authenticity. Our glass options are wide ranging and we are able to achieve U values of as low as 1.0. For homes in conservation areas we use specialist 11mm thick glass that is generally approved by English Heritage.
As part of our installation of new sashes for existing boxes, we always install our top of the range draught proofing system and restore, repair and paint the existing window boxes. We also include new lead weights to counterbalance the heavier glass, and new brass furniture in the original style.
