Doesn't aluminum foil reflective some 99% of the light and heat?

Shiny surfaces will emit less radiant heat but shiny doesn't affect heat emitted through convection.

I've painted my house's roof white and that helps. A relative of mine once covered his roof in an aluminum foil type product that was very reflective. He said it did wonders to keep his house cool. I'm thinking of doing the same some day.

I'd like to do it to my cars, but that would make a lot of people mad at me, I'm sure.
