Condensation on the outside of my windows

Kirkmain

I am the only house on my street that appears to have condensation on the OUTSIDE of my double glazed windows and veluxes. What does this mean? Trying to work out the physics, it suggests my house is too cold relative to the outside; gaseous water outside is hitting the cold window of my home and turning into liquid water. BUT, my house feels warm and the heating is on overnight.

Is it fault with my windows?

No the exact opposite. It just means the ‘air gap’ between your double glazing panes is doing what it is supposed to do: keeping the heat in and keeping the cold out. It occurs at this time of the year because of the high moisture content in the air which condenses on the cold outer panes of your windows.

It happens with brand new gas filled sealed units, proves they are working. Dolor has nailed it.

I aspire to having condensation on the outside of my windows!

Best thing to do is nip out in the morning and write something witty with your finger in the condensation to draw attention to the fact you have the best windows in the street.

Any suggestions as to what to write, anybody?

I get this on my new-ish patio doors.  I am straight out there with a rubber squeegee to wipe them down - clear & cleaned in one action, saves window washing.  A bit like washing my car on a rainy day - automatic rinsing!

If the is any dust or grit  that may be a good way to scratch it up, You need a good amount of water to wash it away first before a squeegee can touch it. I've certainly put plenty of scratches in windows before and had to wash again.

I've also seen a brand new van scratched to bits because it wasn't jet washed first to get rid of road sand and grit.

When I had new glazed panels installed a few years ago they warned me this could happen. As has been mentioned, it's because the double glazing is working. Nothing to worry about. The installers said you can apply some treatment to the outside of the glass to prevent this condensation but they didn't sound like it was worth the effort.

Our windows do that at this time of year and in early spring.

As others have said. It just means that they are doing their job. Nothing to worry about.
