Lead Balance Sash Box Window
The best thing about the sash windows that we do at DM Windows is that they are NOT at all different to those back in Victorian and Georgian times. Well, not on the outside, to be precise. Of course, standards regarding performance, thermal efficiency, glass units, treatment for timber and security – they all changed. The funny thing is though that all of those could be innovated, improved and developed depending on the need and the law requirements but these are things that can remain hidden, so to speak. However, none of it changed the immortal looks of the traditional sash window one iota. This is the mark of an ingenious design – one can improve the whole thing without actually changing a thing!

Our timber sash windows are manufactured from the highest quality of timber and being constantly improved and innovated. Moreover, they can be tailor-made to suit any configuration. They can accommodate single, slim-line or double glazing to help meet the requirements of architects, planners, contractors and individual customers alike. Using classic design and solid craftsmanship, our manufacturers create bespoke vertical sliding sash windows to match the original design in order to retain the period character of your house. Each of our traditional windows is made to fit the original opening exactly, to provide a timeless elegance and sophisticated finish. Unique draught-proofing in our sash windows overcomes the old problem of cold draughts associated with sliding sashes, thus maximizing heat retention.
