Are Capillary Tubes necessary from 800′ to 4000 ‘ elevation?
Does anyone have any experience shipping Insulated glass units into higher elevations?
New Triple Glazed Argon Gas filled windows are being manufactured in the Northeast and being shipped to the Southwest high desert.The highest elevation the shipper will encounter is 4000-4500′ Max.
The weather is very dry most of the year in the high deserts..

Steven,
I'm adding a comment to your question in hopes that some GBA readers will respond. If I were you, I would direct my question to the window manufacturer.

This thread is old, but I was looking in some information about a similar topic. I found this article "High Elevation Problems Jeopardize Gas-Fill Windows" at Building Green website very educative:
