excessive condensation on double-glazed windows.?

Question

every morning I am getting excessive condensation on the inside of double-glazed windows and on one particular 1st floor bedroom inside wall corner.
The house is mainly of stone construction and I am concerned this could be damp in the atmosphere that is causing the condensation.

Answer 1

the seal of the double glazing is not intact, thats why cold air meats warm air and causes condensation, have a closer look at it

Answer 2

Double Glazing Condensation

Answer 3

condensation on the surface of your window is caused by warm moist air coming into contact with a cold surface in which the air reaches its dew point and condensates on that cold glass. A famely of 4 can creat up to 61/2 gal of moisture in the air due to every day activities like showers, dish washers, etc. etc. even plants can contribute. You would either have a poor air circulation in those areas or your glass is colder then it should be. This is normal for single pane glass but shouldn't be on insulated panels. If the seal of the panel has lost its seal . It would have the condensation between the glass. So it is most likely that cold air is infiltrating around it to cool the glass or that part of the home has more moisture in the air and possible less air circualation. Try holding a match around the frame to see if air will blow the flame sideways. If does seal the unit. Try a small fan running in the area on low and check to see if that helps at all. Is that part of the home cooler then others? Warm it up. You obviously have a cold surface or a moist cliamet in the room. You may also try a dehumidifier if sealing and warming does not do the trick. Homes are sealed so much more now days then ever use to be. But keep in mind that warm moist air is harder to heat then cool dry air. Try to open a door or window every so often to ventilate. Doing these tests should help you to figure out what is needed to correct your problem.

Answer 4

I had new double glazing fitted last year and immediately the weather became colder I had the same problem - It is because there is humidity in the room, and am pretty sure if you had a damp meter, it would show the walls in your 1st floor bedroom has more damp than anywhere else. Old houses with stone walls always have a degree of damp and its not normally a major problem. Increasing ventilation and heating will alleviate the situation.

If you don't want to increase heating/ventilation, the cheapest way to get rid of the damp on the windows is to nip to Woolworths, buy a box with crystals that absorb moisture and put it on your windowsill. Costs about £3 per box and then cost for refills. I have had to do this in both bedrooms because doors are shut at night and I only heat the rooms for about 30 minutes in the morning.

Answer 5

If you sleep in the room, then sleep with the door ajar. 8 hours worth of cutting the Zs produces a lot of moist air & it's going to go some where.

If the condensation is BETWEEN the panes of glass then yes, your seal has gone and air has got into the unit and it will need to be replaced, but I don't think that this is what you are describing.

If the window is on a north facing wall then this will be the coldest spot & will get most condensation, which forms when moist warm air cools and cold air can't hold as much water as moist air.

you can only get rid of condensation by: ventilating; heating; dehumidifying (buy one); or by not putting moisture in the air (don't dry clothes inside; vent when cooking; don't breath etc etc!)

You need to open your window more often. The condensation forms when hot moist air from inside the house hits the cold glass. If you sleep with the bedroom window open and a gentle through draught then it should stop the condensation.

Answer 7

The bigger question is why the window is so cold on the inside. My guess is either the window has failed or the seal around the window has failed. Check the flashing outside. If it is not in tact then you probably have water leakage that is rotting the outside casing. Or it could be as simple as no one insulated around the window casing and just put the trim up around the window. Pull it off and have a look.

Answer 8

Many potential problems.

-Windows could have air infiltration and not insulating...replacement required.

-Air leaking around the window...find and seal with a feather. FLame could do it too, but danger of fire...

- Inside air is too damp...HOWEVER, if the other windows are not affected.likely this would be because of poor air circulation. Is the inside room colder? If so, the room may need to be warmed to raise the dewpoint.
