Cold double glazing
just wondering, i have a double glazed bay window and can feel a cold draught constantly from the bottom of each window.this seems to cause excessive condensation on this window compared to others in the house .have had a good look around outside checking for holes/gaps,all seems fine Upon removing the bottom internal beading off one panel,there seems a lot of gaps under the glass which i presume the cold air is blowing into the frame just wondering if this is normal?
When removing the glazing bead which holds the glass in it is normal to have a gap around it, when the bead is put back in their should be enough pressure on the gaskets to keep out drafts. Of course this depends on the age and condition of your windows.
If they are in good order and they are working correctly a draft could come from under the internal window board (check for cracks).
Somtimes if the window is behind curtains or blinds a cold spot can form and because cold air falls downwards it feels like a draft.
A draft wouldnt cause condensation, is the window in a bedroom.
