Storey and a half house. Renovating kitchen. Removed old insulation in ceiling along with GypRock. Installed recessed potlights (IC type) inside large plastic shells (vapor barrier. I am going to reinstall new insulation and cover the hot side with vapor barrier before installing drywall. My question is: With the recessed lighting vapor barriers, do I leave them empty or do they get illed with insulation as well? These units have about 1/4" clearance to the floor.
