Case Studies

Triple Glazed Sash windows with historic leaded panels encapsulated into the glass unit in the Linthorpe Conservation area of Middlesbrough

This project involved renovating the existing bow frames and restoring the original historic leaded panels then encapsulating them into triple glazed units

The client wanted to reain the original leaded panels in the top lites of the box sash windows. We removed the original lead panels, and after restoration and cleaning encapsulated them into triple glazed units then glazed them into new sashes which were installed into the original box frames. This gave the client the benefits of insulated glass units while keeping the historic features of the windows. At the same time we installed our Draught sealing system into the box frames so the windows could still operate for ventilation, but without the draughts associated with box sash windows
