Makes one wary of spending too much on exotic gas fills.

Now here's a thing - I went to the factory today. It's not big, and I
could see all corners of it and units at all stages.
I couldn't see any gas tanks or any sort of facility for "gassing up"
units. Is it possible they order them in from someone else? Or send them
off to be filled? Or is it possible that, as no-one will ever know what's
in them, people just quote for a gas and fill them with air?

Do they make the actual glazing units there or just the frames?
