Airsealing New Recessed Lights
Just had our 1960s home fully rewired. I did a lot of air sealing which is still in process but so far I’ve lowered our blower door result from 7.0ACH down to 1.8ACH.
We had halo recessed lighting added to our living room (the energy losses…gasp!) but I made sure they were ICAT rated at least. To my disgruntled surprise, these cans have tons of holes in them, which I’ve read is not unusual. I’m not sure how they are considered air-tight but ok.
Can I simply tape these holes shut? (Red circles in the picture) They are on the exterior of the recess can. I see no reason why not as they are rated to be air-tight but also questioning why they are there in the first place. The bulbs are LED.
I’ve seen the retrofit domes that fit over old recessed lights, however, taping seems way simpler plus I can keep the insulation right next to the can in the attic.
