OK - just how does this thing work?
The shade is obviously blocking sunlight from coming through that windshield.
But for keeping that car's interior cooler, is the reflective surface any more effective than a non-reflective surface? Would a similar shaped piece of cardboard accomplish the same thing ("shading" the interior)?
I guess what I'm getting at is, the shade prevents the sun from hitting the seats, etc. But the windshield glass heats up, with or without the shade. So wouldn't the hot windshield transfer heat into the air of the interior by conduction and convection?
