    I'm getting alot of condensation in our bedroom window, which is a bay window. The rad is in the bay, and altho there are roller blinds, we close the curtains across the inside of the bay at night. the windows are double glazed and the house which is 2 storey, was built in 2005.

    The seal could be gone on the window.
    Is there a draught under the window? ( Could be a gap between frame and windowboard.)

    What material is the window made of upvc or teak?

    Do any other windows have the same problem?

    Is the water on the glass or between the sheets of glass - in the gas cavity?

    sometimes, if you have heavy curtans, and you pull these across windows... they, in fact, act as an insulator... they create a second air cavity between them and the window...

    this air cavity isnt at the same heat as the bedroom.... the window transfers heat outwards.... therefore the colder air in this cavity is less able to carry the moisture created in the bedroom, fom natural humidity and exhaltion breathe......

    when this moisture laden colder air touches a cold surface, such as the glazing.. it causes condensation to form on the window...

    IF this is the case, and the seal in the double glazing isnt broken (if it was youd expect to find condensation between the panes of glass) then its something i wouldnt worry about....

    set the rads to come on a half hour before you get up...


    PS... make sure your vents are open!

    Hi Marzic
    It souns like a lack of ventilation in room. Do you have vents in room ? Warm air will give you heat when your cold but as it cools it condensates and hence condensation will from. First try leaving a window slightly open some evening and see what happens you will find it makes a difference. If it does then you need a wall vent. Maybe the vent is already there and you blocked it up to stop draught. Everyone usually blocks them? If you did open it condensation gone job fixed
