How to seal this recessed light?
We always thought it was cold in the living room of our new house and I noticed a big draft coming through our "eyeball" can lights. Climbed up in the attic and took a picture of the lights (shown below). There is also no insulation in the ceiling over the last 10 feet of the living room which has no room above it, so I'm calling the builder about that, naturally. Anyway, assuming the builder is going to come put insulation up there, is there anything I can do to seal these can lights? I was going to buy a cover for it, but it looks pretty well sealed. Can I add spray foam all around the joints or something, or should I still do a cover to seal it off? I'm sure having insulation there will make a big difference, but I was still noticing a big draft out of each can, making me think I need to seal it as well.
And another lesson learned: seriously, double check every significant aspect of your build. Had this area of the attic not been accessible, or had I not climbed up to inspect the can lights, it would have taken years for me to notice the lack of insulation. What the heck?!
