Answer 1

Yeti’s cups and coolers can do that because the walls are vacuum sealed, so there’s no air in there to transmit heat in or out. The process to build those works fine in a factory, but it would be INSANELY expensive to build a house out of that. And then, one tiny crack and you’ve lost all the insulation in whatever chamber cracked.
