Grid in only one IG cavity for Triple-Glazed

[nipu...@gmail.com]

Hi Everyone,

I have a question regarding an IG unit with a grid inserted in one cavity (as shown in the attached picture). What material should be used in the second IG cavity, which does not contain a grid?

Thank you for your guidance.

From my understanding, it should be the same argon + air gas fill, but I wanted to double-check with you.

It seems that you should check with the manufacturer to how they handle the argon fill for the two glazing system gaps.

Looks like a question on the NFRC certified simulator test.  What a coincidence.

Thank you so much for the feedback. I will ask the manufacturer about it and run the simulation based on the feedback.
