Just one brand, there are more than this, but basically… NASA invented fancy-pants aluminum bubble foil, literally to protect astronauts and equipment from 100% unadulterated sunshine.

It is stupidly cheap for how well it works.
They basically open sourced the patent, but, the industry that makes insulation stuffing your attic is extremely not fond of this stuff, as… you basicslly only need 10% of their product, if you line the inside of your attic with radiantbarrier.
I got like a 10’ x 4’ sheet of it, put it between the two panes of my south facing window. Definitely works, makes the AC’s job significantly easier.

If you look into building codes in North America, you’ll find out that they were almost all decided by industry board rooms with no public engagement. You don’t need a conspiracy to make every cheap and sturdy form of construction illegal, when the people that wrote the regulations were literally owners of Portland Concrete, several timber companies, and several “insulation” companies. You don’t need a conspiracy when a group of rich people just acted in their own self interests.
