I know there are lots of threads about misted double glazed units, where the unit has failed or the silica gel has gone etc but this is a different sort of thing.
We have had the windows 3 weeks. All seems OK, and in the shade or when the sun is not out the windows look perfectly clear.
However when the sun shines through, the windows take on a misted appearance - however it does not look like moisture as it is completely even all over the pane - and in fact if part of the pane is in shade that bit looks clear, and only the sunny part looks fogged up.
It's driving the Mrs mad - she has cleaned them about 10 times since they have been installed but they just look like they need cleaning again when the sun is out.
It's a weird effect - almost like the colour of a thin coat of clear varnish - almost whitish in appearance.
I have notified the installing company and they are sending someone out from their glass suppliers but I'm just wondering what might be causing this - it almost looks like a residue on the inside faces of the glass, or can it be a reaction to the warmth / light from the sun?
Cheers.
Chris.
