Hi, does anyone have advice/tips on removing condensation between the panes/cavity in double glazed windows?

Answer 1

It's goosed. Get a new unit. The condensation will eventually dry leaving a crystalline deposit. And there ain't nothing you can do about it.

Answer 2

The window (the glass part only) is considered a thermal pane or insulated glass. Typically once the seal has gone the window is junk. The condensation may go away at times but it may leave an ugly cloudy appearance between the layers. There is sometimes an invisible coating or some type of gas inside the two layers so when that seal is compromised almost all the insulating properties go away. Is the window covered under any kind of warranty or did you price out changing the glass only(not the whole entire window from the framing)? Unless you are a serious DIY'er or have a few dedicated friends I wouldn't suggest the following but here goes... Take the glass out, clean and inspect the entire perimeter. Hopefully you can determine where the source of the leak is. If not,(assuming at this time the condensation has dried up) you can sit the entire window in a nice bead of silicone all the way around. This is very inexpensive but VERY ambitious and if done early into the detection of the leak this just may stop the clouding. I wish I had an easy answer for ya but good luck none the less.

Answer 3

It is not "goosed" and it is also unlikely that the seals on the windows are bad.

When a double glazed window is assembled, there is a dessicant (moisture absorber) in the bottom of the channel separating the two panes. Over time, this dessicant has absorbed all it can - this is why you have condensation.

A single pane has an R-value of about 1. A double pane is about 2.3, so it is only a cosmetic problem.

I was at a seminar over the summer and the speaker stated that there is a new process under evaluation by the U.S. Dept. of Energy that would correct this problem. When doing so, an approved tech would drill into the pane, dry out the area between the two panes, and add more dessicant to the bottom of the window.

There may be a limited number (or only one) person in your entire vicinity that can do this. There isn't that much demand for it because so much of the public believes that the windows need to be replaced and there's more money in replacement windows, so I wouldn't expect too many of your window guys to learn how to do this.

Check out this website to learn more and to find a local company that can do this.

Answer 4

Unfortunately, the pane of glass must be replaced. The seal has been broken.The condensation will eventually dry out on it's own, but the reason for this condensation will still exist and the glass will not be clear. Joie de la Vie has suggested you take a blow dryer to the window. I'm afraid it's not that simple. Especially with cold weather, you will end up cracking the glass. At least you can get through the winter and worry about it next summer.Some of these do not have to be replaced right away. You can go several years with them. But will eventually crack on their own over time, which is what happened to ours. We had them, (several panes with a broken seal), replaced slowly. So we did not feel the pinch. We did not have to install a new window. Even the more newer Low E Argon Gas windows have this problem. But most companies will give a lifetime guaranty.

Answer 5

I would say the majority of the answers above are wrong and i wonder if the answerers have ever tried to fix a condensting DG unit.

EDIT: I've notices several people seem to have success with the same method as me, there you go, what can you loose ?

I've seen this once, and assumed the pain seal was broke and i'd need a new window pane.

But actually, i cured it.

Heat the room up, warm the flass gentle with a hair dryer.

The condensation went away, 2 years ago, and hasn't come back.

Answer 6

You could try taking out the glass panel which is only kept in place with moulding. Then use a hot hairdrier to dry out window then reseal all around the edged of the pane with silicone and re-fit.
If this does not work you would have take it to a glazer to re-seal or buy a nes unit. It might be cheaper to buy a new unit just like when the head gasket in a car goed it is not always a success to have it re-done

Answer 7

your advice is in the Q, the condensation is there because the seal has been broken and you will always have dampness until summer.
remove the window in the slider and take to window shop that does duallys.
or purchase a retro-fit window new and replace.

Answer 8

if you dont have much cash and need a quick fix til you can fix properly
warm up the room (i hope all the windows are not doing this ! ?)
as i said warm up the room take a hair dryer and hold about 12-18 inchs away from window this will take some time.......
I had to do this to mine last year,,,,,It will take awhile,and yes heat does cause condinsation but it will for a quick fix.....................This is not perminent..........................
but i,m having pretty good luck with mine....(fingers crossed now )lal good luck

Answer 9

If there's condensation between the sheets then there's a leak, which means the windows have met their timely end.

You can get them re-sealed (by a professional), or replace them entirely, whichever suits you best.

Answer 10

Agreed, goosed, You should be able to replace the glass pane much cheaper than having to spend money on a whole new frame though.
