How to build traditional windows
Mar 31, 2026This winter, I built a small batch of oak windows for the new boat school workshop. The windows are replicas of other windows in the building, which presumably are from 1862 when the house was built.
In this short video, I outline the process, including joinery, assembly, glazing and painting.
The sash corners use bridle joints, and the muntins (glazing bars) are assembled using mortise and tenon joints. All joints are mitered.
The glass used is restoration glass by the German manufacturer Schott. The glass is produced using the so-called "Fourcault process", which results in a slightly wavy glass that I think is appropriate for this type of building.
The windows are glazed using linseed oil putty and painted with linseed oil paint.
Although this is not boatbuilding, I hope you'll like the video!
