If you want de-humidifying the best thing is single glazed sash
windows. They condense a lot which then drains down and out to the
outside via the gap at meeting rails and at the bottom sash staff bead
junction.
Double glazed and draught proof windows keep humidity in and although
there may be slightly less codensation on the window glass itself (it
being warmer than a single glazed window) there will be more
condensation in other parts of the buildng sometimes resulting in damp
walls, mould patches etc. If there is inadequate ventilation there will
be more condensation on the DG windows than you would have had with SG
windows, due to the higher humidity levels.
One (stupid) answer to this prob is 'the de-humidifier' - an item which
was virtually never heard of until double glazing and it's probs
emerged. A more sensible answer is to open the windows a bit, and keep
a window-leather and bucket handy to wipe off condensation.
