How to airseal I/C and A/C potlights?
The builder installed approx. 40 pot-lights in our ceilings.They were made in China. I suspect that he wanted to hide the ripples and dips in a poor GWB installation.
I have never been a fan of electrical components manufactured in China and I have a concern regarding the air-sealing properties of these particular lights. When you view across the edge of the sealing trim ring, you cannot see any of the open cell foam gasket. It is doubtful that the gasket provides any sealing properties what-so-ever.
These pot-lights were available at Home Depot a number of years ago. I see now that the newer pot-light gaskets sit proud of the trim ring and are of a more dense foam.
Will replacing the newer style gaskets, to reduce the air leakage to the Attic, be worth the added expense?
