Nowadays your glass isn’t just glass, it has coatings on it that change its optical properties. It’ll have anti-reflection coatings between the panes, for example, and the outside face of the outside pane might have a bit of UV blocking tint on it, or something to reflect heat.

There is a special coating on the inside of the outer pane called a low-E or low emissivity coating. It is basically undetectable unless you have a low-e meter.

Do you think it could negatively affect the installation to have them the wrong way around?

Most windows are directional in that the exterior side is generally self flashing and have weep holes.

When I did new construction inspections I would fail the insulation inspection and they would not receive a pass until it was done properly.

The frames are in the correct way but some glass panels are in the wrong way around. I'm not sure how much of a negative impact it'll have, or just that I lose the positive impact.
