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.

Contact a local glazier. Obviously windows break, an they wil be able to
give you caper and vrese on replacement DG glass panles,.

One thing is relevant apart from depth and that is bead - the seals
around DG units are quite wide ..You may end up stripping the window
frames and making new rebates. Unless they are nice hardwood, it may be
just as little work/cost to make new ones..
