hahaha, uk all the way.
but seriously though. if its the same material it wont make a difference. whether its concave or convex.
lets take mylar.... i dont see how that would make a difference except for altering the direction of reflection - bo! bo! bo!
and take foil. that will only change the direction of reflection as well, not heat attributes as they'd stay the same!
just the same thing as ur car mirrors. things in the rear view appear closer than they seem...... that doesnt make them any further away. I.E doesnt change any attributes
