I am losing a good amount of heat through my recessed lights. I went up in the attic above and found there is insulation around them, but not on top. They are IC (insulation contact) rated. Is it okay to just put more batt insulation on top of them, or is there a better way? I'm hesitant to cover them because of the wiring.
The IC rating means that the entire can can come into contact with insulation.
