Our Traditional Box Sash timber window range has a true weights and pulleys system that provides a direct replacement for an original box sash window or creates a high-quality traditional look for a new build. The cords and weights mechanism works by counterbalancing the weight of the window with a lead (iron) bar attached to a chord that rolls over a pulley. This enables the sash window to slide up and down with relative ease. With this window, you can get the look of an authentic timber box sash with all the modern benefits.
