You can’t, a window, by definition, is not opaque. You cannot define wood in place of glass.
Are you wanting to define a wood frame? Or you want to define an opaque wood surface, like a door or shutter?
Both are possible, if you want the former, you need to create a complex glazing build up and account for wood material properties in the frame. If the latter, don’t use a window object.
