35mm sounds very thick.
Are we talking about a glass unit that could be used to replace an existing
pane of glass, if the rebate were deep enough.
I guess I'm off to a non-start here, since I have 1930's windows with no
more than a 20mm rebate.
Just that the 1930's windows are sound, look nice and they knew how to
season wood in those days!

Mine are 20mm total thickness - the 'spacer bar' in the middle is 12mm
and the glass is 4mm for each pane. The spacer bars come in other
thicknesses too.

I presume Scott's window sizes should be in cm, not mm, in which case
£40 all in was *very* good price.
