I live in a condo, and I'm just noticing condensation between the panes in a 7yr old Velux skylight that was installed when the roof was replaced. Actually, there is a 2nd skylight installed at the same time, and I believe I'm also noticing a slight amount of condensation between the panes on that one as well, but it's not as noticeable on the 2nd one.

If I don't care about the fogged appearance, and if I don't care about the loss in energy efficiency, is it okay to leave them be? These are the kind of skylights that doesn't open or close, and I'd rather not get involved with replacing whole skylights on the roof, unless the skylights were actually leaking water (since there's always the chance that a water leak could happen as a result of installing in a new skylight, since a new installation would disturb the existing roof, etc.) Also, I live in a condo, so I would have to get the association involved if I wanted to have the skylight replaced, and again, I'm not thrilled about having to disturb something on the roof as long as it is only just a condensation issue. (My philosophy is don't disturb the existing roof unless absolutely necessary) Is it okay just to leave them be, for now?

Thanks,

J.

There is
A- A small air leak past the seal between to sheets of glass.
And
B- The dessicant that is inside the metal spacer between the glass has
been used up.
So condensation appears.
Remove sealed unit and take to glazier & ask for another to be made.

It is just an appearance thing. On a rooflight you will hardly notice.

In the UK there is a ten year guarantee against this, dunno about the
US.

My parents house has several double pane picture
windows, about 3 by 6 foot. One or two has some
condensation btween the panes. Been that way for
several decades, and not done any damage. My
sense is that it's a non issue if you don't mind the
look.

I'm not a glass guy, but you can always phone a
couple of glass companies out of your phone book
yellow pages.

Looking like hell and losing more energy through it are
the only factors. But, have you checked for a warranty?
Velux is a top company and I would not be surprised they
are still under warranty. Also, are you sure it's inside the
glass and not on the inside from humidity in the house?

You might want to check for warranty. We had two fogged windows that are
around 10 years old that were made by a local window company. I was just
going to pull them and drop them off at a nearby glass place but decided
to call the dealer where we bought them. Turns out they had a full
replacement warranty. I dropped them off in the morning and picked up
the repaired windows that afternoon repaired at no charge.

It turns out that it it's not condensation. It's some kind of white residue on the inner-most pane of the glass, and it wipes off with a wet cloth, but not a dry cloth. It's either minerals (or other impurity) from shower steam condensation, or some kind of dust that stuck to the glas, or some kind of mildew. I'm not seeing any water leakage.

The skylight is located in the bathroom of my condo, and even though I have an exhaust fan, it does get some condensation on the inside after taking a shower but it goes away after 20 minutes. The white residue was something I've never noticed before, and doesn't go away on its own, and I thought it was condensation between the panes. As long as the white residue is not the result of any leakage, I guess the skylight is okay for now.

if it were ondensation or worse yet water building up between the
panes. the real hazard is then water freezes and breaks them pane or
panes as it expands . i have seen this happen in pittsburgh with
double pane windows

Got the attention of Velux rep on other group.
