I think I remember reading somewhere that if you have an aluminum can that its bad to use a wrap as it traps the heat in the can and can also make it louder?

Any truth to this?
 
I always use a wrap on my AAC Element 2 (which isn't aluminum). I would never need it for the heat, but instead use it because it looks really neat and it helps protect my suppressor from getting banged around on barricades and such.
 
Other than protecting the Finnish on the can, why would you want to trap the heat?

They do look good but a potholder goes in my gear.
