The issue that I am asking about has to do with the contractors using IC cans and then using AT trims. The claim is that the trim gives them the required energy code requirements. I have to believe that the trims used on the cans need to be Listed for use with that can and vise versa. I think the installer should be using AT cans in the insulation envelope to comply with the energy code and the can should be finished off with an AT trim.
