I had some double glazing fitted last year, it was fitted by a FENSA

for 6 leaded windows and a patio door.

We are happy with the windows etc, but in winter sometimes get
condensation on the windows. This only happens on mornings where it is
particually cold and wet out, it burns off by midday, and is worse in
rooms where people have been sleeping.

Nice looking windows. As the others have pointed out your new windows
can only reduce the condensation. I have three suggestions that were not
noted to add.

1. If you have window coverings drawn at night it will increase the
problem. It blocked the cold air up next to the window allowing the window
to cool even more. As soon as the windows gets below the dew point for the
room then condensation will take place. The window coverings will reduce
heating expense but also increase condensation.

2. Your bed rooms are prime for this kind of problem because they are
often a little more moist at night due to people breathing and adding
moisture to the air.

3. Condensation results whenever the humidity in the room goes above the
dew point of the cold object. Things like curtains reduce air flow, but
moisture goes right through them.
