Double Glazed Sash Windows

This week I have been working on sash windows again. I often get asked if it is possible to double-glaze existing sash windows. The answer is yes and no, it will depend on the style and condition of the window, and also on whether or not the property is listed etc. Building regulations also control what can and can’t be done. The sashes pictured here have been made to fit into existing frames and support double glazing. Additional lead weights are used to balance the extra weight of the glass.

If you have any questions regarding sash window repair, refurbishment or double glazing, please get in touch.
