LowEargon windows?

[m Ransley]

Is there any way to tell if new LowEargon windows by a no name company are in fact LowEargon other than sending it to a testing lab. The panes are spaced further apart than my standard Pella and Anderson , which is suspicious because there is a maximum spacing for efficiency Pella and Anderson would use. They have a rivet-plug protruding into the glass area 1" through the aluminum dual pane spacer. Im suspicous of overall quality as even corner gaskets are bent not mitered and pulled away. They just look cheap, and knowing alot can be saved fleecing customers I need new windows verified as purchased.

Hold a lighted a match near the inside glass. You should see a different color on the low-e coated pane which is the inside of the outside pane (3rd of 4 reflections)

Just so you know, they are not always packaged together. You can have an argon filled window without low-E, and you can have a low-E window without argon. Some windows are made with just air between the glass. Some manufacturers apply the low-E coating to the glass after it is made, but some apply it while it's being made, which isn't as easy to see. If you live in a northern climate, a low-E coating is not nearly as important as in a southern climate. If the label says low-e/argon, then it probably is, but if there is no identification, then it might not have both. Try to find out who made the window.

If you can find out the name of the mfg, you should be able to find out if they are both low-E and argon windows.

Argon would glow blue with a high voltage discharge near the outside of the glass...
