Double glazing old sash windows.

In this video I want to show you how to retain the original wooden frame when renovating and upgrading sash windows from single glaze units to double glazed units.

The methods can be used for single wooden windows or for the more traditional two piece window frames.

For me it is important to retain as much of the original structure when renovating an old house and with modern materials and equipment the task is quite straight forward. You just need a little time.

Tips for the Traditional Sash Window upgrade.

Here are a few tips for working with the traditional two piece sash windows.

With the house in this video, the traditional sash window weights which were cast iron, were removed and replaced with heavier lead weights to make up for the extra weight of the glass.

To attach the sash window to the sash chord I rebated a slot in the outside of the window and used cleats to retain the chord.

There are companies that sell sash furniture and parts that make the old sash frames to become draft proof so it is well worth the extra work.

Thanks for watching.
