PVCu french doors - buying unglazed
 

Can you save money by purchasing unglazed PVCu french windows and
getting double-glazed units to fit ?
If so, where can you get these, and how can you get round the "trade
only" / "we don't retail" fuss ?
I know some windows require de-glazing to fit anyway, although screwfix
etc, seem to have tags that fit into the frame so that glazing need not
be removed.
Cheers,
Simon.
