Double Glazing - Condensation outside

[badgermansix]

Hello,
In May we had our old dg Aluminium windows replaced with the white plastic type.
now that the weather is cooling a bit we are finding that the outide glass is condensating (on the outside).
This has never happened with the old.
Why is this happening, and is this normal?

tia.

This is a good thing!
It basically means that your windows are insulating well and not letting the external pane of glass warm up.
As the external pane of glass is cold, when there is moisture/humidity in the air it could condensate on the cold surface.
If you had poor insulating glass units the external pane would get warmed by the heat escaping from inside your house and this phenomena would not occur.

It's quite common in higher performance windows and will clear quite quickly as the sun rises or the external temperature increases.

As Phil above; it's one of the less desirable atributes of modern thermally efficient windows which they never tell customers about but it does mean your DG is doing it's job.

Agree with both replies above, it seems as its the nature of the beast with 'A' Rated windows. On the flip side some people say we are making our homes too efficient and causing problems elsewhere but who are we to argue

I will
that'll be condensation then & the black s h ite that goes with it; it just loves a hermetically sealed environment & will thrive on damp, be it your bath/shower room, cooking, drying washing in the house or just 2 people breathing in bed at night! For some strange reason, open windows & “fresh air” no longer seems to be fashionable & we’re already starting to see legislation being introduced to compensate. No wonder the younger generation, of which I have several, suffer god knows what allergies & breathing problems but they wont listen (that’s sounds really crass ). And they don’t eat enough dirt; me dear old mum used to say "a teaspoon a day + the odd worm/bug is about right"

Sorry, bit of a rant there

Call it 'dew', it doesn't sound as bad as 'condensation'.

You could use it as free distilled water to clean the windows.
