Secondary Glazing

I have had the opportunity to work on a stained glass window in a cottage located in Carstairs.  The lintel over the door has the date 1762*.  A lot has been done to the building since then, but it is good to see it standing.

My task was to repair four broken panes in the bathroom and establish secondary glazing on the outside.  This is the only window that is not double glazed at the back.  It is in a steel frame, so that probably puts the window in the 1920's  


The repairs required are at the bottom corners, next to the right lower rose and the pane covered with black tape.

The repaired and cleaned window now has this appearance:




Meanwhile, the establishment of a timber frame for the secondary glazing was going ahead.  The frame needed to accommodate the hinges on the left outside and the slope of the base of the window.  The frame was attached to the sides of the opening and sealed at the top to prevent water entering there.


The frame was made square so that there is ventilation at the bottom of the frame to prevent condensation building up between the two panes.

The picture below shows the trial of the glass pane into the new opening.





The final picture shows the secondary glazed window in place among the double glazed windows.



This was a satisfying project to complete, as removing the steel framed window would have presented a completely different appearance to the stained glass that was made to fit its present setting.




* The lintel is a copy of the original, and I did not want to identify the location, so I have not taken a photograph of the front of the building.
