Condensation on New Windows

JohnSwift10

I got new double glazed windows installed a few weeks ago and when I got up this morning and opened the curtains I couldn't see outside for the condensation that covered them on the outside and when I went downstairs the French doors were also covered in condensation on the outside.

Is there anything I can do about this or will I just have to wait until the sun shines on them?

I wonder if they will get covered in ice in the winter?

This happens to my windows too & research I did showed that it actually isn't a bad thing & more inclined to happen when your windows were doing a good job of insulating your home. See below.

Should double glazing get condensation on the outside?

As the surface of the glass is cold, the air around it reacts with this temperature and condenses, creating moisture on the outside. ... If you have condensation on the outside of your double or triple glazed windows, then it's likely to be because they're doing the job they're meant to do.

Exactly as Cattie says. This shows they are working, by preventing the heat from your home escaping through them - that leaves the outer surfaces colder than on the old windows, which is why moisture condenses on them.

No, it won't freeze in winter as it'll still be comfortably above freezing temp (unless your inside is freezing too!)

Yep mine do this - not all the time mainly this time of year, always on outside. Then clear.

Energy efficient and doing their job preventing the cold from getting in . Much improved multi chambered frames and thermal efficient glass . gaining a full thermal break between in and out . can happen at any time but now is a good time with cold nights and warm days

The only time my windows do that is when it’s warmer outside than it is in the house

We've got this on our new windows too.

Condensation on the outside? 

That's the opposite of how it works.  I grew up with condensation inside but we've moved on from single glazing and me still remembering what the slightly rotten woodwork on the window interiors tasted like.  

Don't ask.  I have no idea, but I had a boyfriend who ate the asbestos walls of their post-war prefab and he hasn't died yet, so I'm hopeful.

Yep, on the outside, very rarely, but when it’s an exceptionally warm night in NE Scotland, and the inside is cold.
I never have condensation inside, always have the vents open

Okay.  We have new windows and it's nearly every day.  More noticeable now the sun doesn't hit the windows as early.  

The snow sat on the rooflights for days last year.

My windows are new, but it also happened with my older windows in last house. I think being by the sea there is a lot of moisture in the air.
