As you can see below, traditional glazing bars have very small rebates to accept the glass. Modern double glazing requires a glazing bar of at least 40mm to contain the unit propperly and secure beading.

There is also the proportion of a conventional modern double glazed unit, they are are normally at least 24mm thick which exposes a lot of spacer bar.

The range of wood we have found best for making windows are Oak, Idigbo, Iroko, Sapele, Accoya and European Redwood (often just called "softwood").
An overhall of our reception area was well overdue.
Being a joinery workshop much of the timber we use is hidden, painted or from a few very popular species that gets used a lot.
Plastic, aluminium and other materials do have their place, but for an authentic period home, timber windows are essential.
