Is there any simple test to perform if Low E was put on proper side of panes and if Argon is still intact? We are having problems with cleaning our new windows. They have a white smeary film on them only visable when the sun hits them. I don't think its between the panes because it seems to move around. We've tried everything to clean them. Window rep seems to think there might be a silicone on them from the factory that is not removing. Some people seem to think it's a Low E problem or Argon escaping the panes. Any suggestions?

Greetings,

A flame placed near the glass, (not too close), will show the reflections of the flame in the glass.

You should see a green tint in one of the reflections, (I think it will be the third one.), and that will be the low-E.

Argon gas will go away all on its own! It just happens.

How old are your windows?

Good luck,
Jason

Our windows are brand new. You said the argon will escape on its own. It is not supposed to do that is it? My understanding is that is a part of the insulation and efficiency of the windows.

Greetings,

I grew up in the window business and I have been told by every manufacturer I've ever delt with that the argon will last about 5 years or so before it disapates.

Good luck,
Jason

If the argon disapates does that effect the insulation? Or does the Low E take care of that?

low E stands for low emissivity. It is a coating applied to glass to reflect radiant energy. It has little to do with insulation. It is to reflect UV rays that can damage your furniture, fabric, and wood floors. It also reduces your AC loading in the summer.

Loss of the Argon fill may reduce your insulative value slightly but not enough to worry about. It's just that Argon is a little more efficient than a pure vacumn. It's somewhjat of a sales gimmick in the quest for the holy grail of the perfect window, whioch doesn't exist, IMO.
