I have some quite large timber-framed casement windows in the front of
my house. As the frames are in serviceable condition, I had wondered
about replacing the glass panes with double-glazed units, in the same
frames, as a less expensive alternative to having the entire windows
replaced. I think the frames are deep enough. Has anyone done this?
Would I simply bed the units into the rebate, in glazing silicone or
similar, put some beading over, and job done? How thick are today's
standard DG units? Can one get them made to measure? Who makes them,
and how much do they cost?

I've searched the archives, but couldn't find anything on this.

Basically not possible. DG units too thick, heavy, and have wide seals
which wouldn't be covered by the rebates.
Waste of money too, DG is generally not very cost effective. Plenty of
cheaper alternatives e.g. heavier curtains, 2ary glazing, etc
