I’m not really into her style, but she does have a lot of footage of the landscapes and the kinds of buildings they have and stuff.

I’m kind of surprised that her house has so much glass in it, but I guess if you get fancy-enough windows, you can probably get decent insulation.

With double pane windows, you get an R-value of 2 – 4.1. Meanwhile, with triple pane windows, the R-value is from 3.2 and up to 5.5 with 1 Low-E pane. With 2 Low-E panes, it can improve up to an 8.7 with argon gas filled units and up to a 9.9 with Krypton filled ones.

It looks like new exterior walls in the colder parts of the US use R10 insulation (in addition to the siding itself and drywall, which I’d guess doesn’t contribute much):

Insulated 2x4 wood-frame wall:

For Zones 4–8: Add R10 insulative wall sheathing beneath the new siding.

…so in theory, if you have really high-end triple-glazed, exotic-gas-filled windows, they can insulate about as well as a wall.
