Translucent, but not quite transparent.

That’s fine for skylights and for basement windows.

Looks like this substance might last longer. Will it stay transparent? Will it deteriorate from UV?

The insulator is the air. But there are better insulators than air, argon for example.

I don’t know what gas the aerogel used, but generally anything denser than air is an improvement. Argon is good because it is readily available as a by-product of liquid nitrogen and liquid oxygen production.
