A window fitter I know doesn't like argon fill etc as the customers complain of this external condensation,
I presumed it just meant the windows are working well as a insulator ?

nice windows , will you be putting some costs and supplier on your site in the future ? could be helpful for people.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63803#Comment_63803 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63803#Comment_63803 Sat, 10 Oct 2009 11:10:14 +0100 Paul in Montreal Posted By: tonyCan you tell me why?Same reason car windows get condensation on them on the outside. With damp air and a clear sky, radiative cooling of the surface brings it below the dew point. Because your windows are good insulators, there isn't enough heat flowing through them to keep the outer surface above the dew point.Looking at the photo I can see that the sky was clear.

The only solution I can think of if it bothers you is to treat the window surface with something like the products one sometimes sees that are supposed to prevent car windows steaming up on the inside. I think some glass now is available with a self-cleaning coating which may do the same thing.

I came to the same explanation that Paul suggests above (although not as eloquently put). Its never been a problem with crappy old inefficient 2G or 1G windows so it takes a little getting used to. After a while I decided it was a good sign - rather like having unmelted snow on your roof while others are clear.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63820#Comment_63820 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63820#Comment_63820 Sat, 10 Oct 2009 17:42:43 +0100 Jeff B https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63822#Comment_63822 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63822#Comment_63822 Sat, 10 Oct 2009 19:16:12 +0100 Julian https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63843#Comment_63843 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63843#Comment_63843 Sun, 11 Oct 2009 15:47:01 +0100 Terry The house with a good covering of snow on the roof and external condensation on the windows is the one to go for - simples.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63862#Comment_63862 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63862#Comment_63862 Sun, 11 Oct 2009 20:34:49 +0100 tony ]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63916#Comment_63916 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63916#Comment_63916 Mon, 12 Oct 2009 14:00:13 +0100 Terry As regards the rest of the ceremony, instead of dancing around outside until the snow on the roof melts, could we not just stick to hopping around on one leg and tying knots in our trousers?]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63938#Comment_63938 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63938#Comment_63938 Mon, 12 Oct 2009 20:09:30 +0100 funcrusher https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63942#Comment_63942 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63942#Comment_63942 Mon, 12 Oct 2009 21:20:42 +0100 Julian https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63952#Comment_63952 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=63952#Comment_63952 Mon, 12 Oct 2009 23:18:34 +0100 tony https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=70089#Comment_70089 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=70089#Comment_70089 Thu, 24 Dec 2009 12:01:54 +0000 SolidWallJim
I live in a solid-walled Victorian terrace with the heating off at the moment (Well, broken actually!) and the outside temperature warms up quicker than the inside in the mornings. I've routinely woken up to condensation on the outside of my double-glazed windows.]]> https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=70112#Comment_70112 https://www.greenbuildingforum.co.uk/newforum/comments.php?DiscussionID=4663&Focus=70112#Comment_70112 Fri, 25 Dec 2009 21:09:01 +0000 davidfreeborough
However, as Tony has triple glazed windows & large amounts of insulation its unlikely to be due to the inside air temperature lagging behind the outside air temperature. Its more likely that the windows have been radiating into the night sky &/or moist air has just arrived.
