Sounds like one of those strictly commercial building materials. Kind of
along the "if you have to ask how much you can't afford it" lines. Too bad
because it sounds like it would make nice skylights for a house too

I can only suspect the cost would be prohibitive, but this stuff is
pretty impressive. An aerogel core with some sort of acrylic casing, it
allows a whole lot of light through, and somewhere it says that a 4 x
35' panel (that is feet!!) weighs only 210 pounds and has an R value of
about 20... Like building with styrofoam board that you can see
through, it seems. Can't find a price though...

They built a lot of Milwaukee's new baseball stadium out of it:

Somebody build a greenhouse out of this stuff and tell me how it works.
