Double glazing was not possible but I quite like this solution. The 'beads' are less noticeable irl.
We had vacuum glass fitted in our original 1930's window frames today.

This had me confused so I looked it up. Vacuum glass is still two layers of glass, just with a much smaller gap between the panes with glass beads or pillars in the gap so it doesn’t collapse when a vacuum is applied, compared to adding argon in a traditional double glazed.

You're right, I meant "double glass" as the gas-filled thick panes typical for modern windows.
On a side note: I read that the isolation of gas-filled double glass actually degenerates over time. The vacuum does not.

Neat!

Oh snap so that’s what those three little dots on a airplane windows are for

I’ve never heard of vacuum glass, but I imagine they put an additional pane on the window and then suck the air out, thus creating a double pane?
If so, a really awesome way to preserve the look of old windows. I wish I’d had that option at my old house.
Is the new glass low-emissitvity?

It is as you suspected. The vacuum has very low conduction of heat and sound and is preserved by the small 'beads', if not, the two panes would simply be sucked onto each other. What do you mean by emissitvity?

Low-e glass lets less IR through it, meaning less solar gain in the summer and less heat loss in the winter which has big energy savings. It’s very common in double glazed windows, at least in the US.

Heat transfer. I suppose these would be "low-e" because of the vacuum, sort of like a thermos.

Paint and caulk make trim what it ain't.... E: thats a good edge on the glass. A good oil piant will preserve that real nice and blend it in with the trim

Why oil paint specifically?

Skin and adhesion. Latex paints don't bond well to silicones. Oil skins over to some dense more temperature resistive goodness

Most modern paints would be acrylic with the same bonding problem right?
