Well, disadvantage of only barely affecting temperatures though. 3.5C max, 0.6 average is not nothing, but for me at least, part of the problem is the fact that if I don’t run AC, the temperatures just keep on climbing indoors. The 5-6C drop of tinfoil sounds more useful, but then they didn’t really mention what the average drop is.
Granted, I realize most people would rather get light through their windows. But personally in bedrooms I’d rather take 0 light as otherwise you only really get 3-4 hours of dark per day in the summer. For other rooms - maybe some of those heat-reflective films? 3M claims theirs manages reduce heating by quite a lot, but probably not as much as foil.
3.5C is when it’s hottest, which is presumably when it’s most needed.
It’s not a miracle, but 3 degrees is noticeable. And for the cost of practically nothing, it’s something anybody can afford to do if they need to. It’s not just about what’s the best solution, but also about accessibility.

Aren’t window awnings more effective and efficient anyway?
