Metal Box Over Recessed Lights
I went exploring in my attic this morning to find my pot lights and see what I can do about air sealing them. I found they are covered with steel boxes (see photo below). These boxes appear intended for this application but are not something I am familiar with… I am not familiar with anything electrical. The boxes have small holes in them, so certainly not air sealing!
1) Does anyone know the purpose of these boxes? (to keep the insulation away from the light??)
2) Do I need to open these boxes to figure out what kind of fixture I have in order to air seal them?
The idea of putting a foam box around a thing that creates heat feels wrong to me (from a fire safety view), so I was thinking of creating a box with gypsum board, or perhaps Densglass for moisture resistance.
Thanks for your thoughts!
