No they keep the panes separate will tiny metal spacers. Looks awful in my view.

Argon has a (slightly) lower thermal conductivity than CO2 (about
0.1 vs 0.15 W/m/K).Robert
Oh, sorry, ;-)
Thinking back to my "A" level physics, and knowing the strength of glass, roughly, a two foot square pane would have just under four tons squeezing it together. It should meet in the centre of the pane, but the bending stresses near the edges will break it. Unless the panes are thick enough, which would probably mean about an inch thickness of toughened glass. Never mind the spacers....
