When I put them in the corners as bass traps, I put the foil side away from the wall, and when I use them as absorbers, I put the foil side to the wall.

I just noticed a lot of people doing frames. Is there a reason other than aesthetics, and increased mounting ability ?

Have I done it wrong ?

You don't need frames. I did the frames just to make them sturdy and look good.
