Installing insulation in the cavity between LED retrofit assembly and IC-rated can

by Geremy   Last Updated January 14, 2018 08:21 AM

I have some existing IC-rated cans that I can feel (and see with an IR camera) are leaking cold air from my attic into my living room.

When installing an airtight LED retrofit assembly over it, is it safe to:

  1. Seal the holes inside the can with some sort of insulating foam

  2. Fill the cavity of the can with insulation where the bulb used to occupy, (that is now just an empty space above the LED retrofit assembly)
