Sash Windows
sash windows
The design of our vertical sliding sash window is the product of an extensive collaboration between our technicians and consultant architect to ensure that our box sash reproduces, as faithfully as possible, the simple grace of English sash windows progressively developed from early use by Wren through their peak of elegance in the late Georgian period and in common usage by the Victorians and Edwardians.
In particular, the dimensions of our sash frames, meeting rails and glazing bars have been made slim, with traditional mouldings subtly modified to suit modern construction technology.
To carry the extra weight of double-glazed units, our sliding sashes are hung on solid brass chains (sash cords stretch and break) retaining the long proven reliability of simple counterbalance weights.
Quadruple draught strips stop rattles, and extremely high insulation (1.1W/m2K) glazing units minimise heat loss and down draughts. Multi-layer timber and very careful attention to detail, minimise the swelling and warping that causes jamming on windows of lesser quality during wet weather.
