Foggy Windows: Why are my new windows fogging up?

This blog post reviews why you might see fog on your brand new windows.

Has this ever happened to you?    You step into the kitchen to get a hot cup of coffee and notice that the entire window is fogged up.

You freak out.   Didn’t that window guy tell you that a fogged up window is a sign of seal failure?   Didn’t he say that his windows had this amazing warranty so they were guaranteed not to fog up?   You just spent all this money on new windows and now this?

You’re mad.  You panic.

Deep breath.

This is normal. Your new windows are still awesome.

 

Here is the thing.   There are two kinds of condensation that can be on windows: Exterior Condensation.  The kind you can drag your finger through and leave a drippy mess. Interior Condensation.   The kind that is in between the panes of glass.    You can’t touch it.

What causes condensation on your windows?

  1. Exterior condensation is typically found when temperatures outside are very hot and humid, and the temperature inside is very cool and dry.  Like August in MN.  Like today.
  2. Interior condensation is typically found when your window seal has failed – so all the gas has escaped and any wind and water that wants to gather and get trapped in between the window panes is welcome to.

So as you can see, exterior condensation is really nothing to worry about.   If it is indoors you can reduce humidity.  If it is outdoors you can be happy that it is summer because we all know that in Minnesota, summer is fleeting.
