Do you think using a 1 gallon metal paint bucket as a barrier in the attic over 3" non-IC rated recessed lighting will cause any heat problems?
I've been looking for ways to keep the blown in insulation away from my recessed cans that will also allow me to seal and insulate over them and thought this would be a cheap way to go. It seems safer to me than plastic or a hand made foam board box. I plan to use fire-rated caulking around the perimeter of the can to seal it to the attic floor and make it air tight. I'll probably slap some HVAC mastic on the can's seams for good measure and then insulate directly over the paint bucket.
