I am officially at the begging stage... Here's my story:

Bought a house with 30 Halo 6" recessed cans, H7's. Cathedral ceilings
throughout the house. I can not get "behind" any of these fixtures.
The cans are original installs, which means they are not the retrofit
models... they have a large frame around the cans. They are NOT
air-tite, and are NOT insulation contact rated. They are,
unfortunately, the cheapest Halo 6" recessed cans the electrician could
have installed 12 years ago. When you put your hand near these things
you feel WIND... not air movement.... WIND. There is insulation in the
roof, just not near the cans.

I NEED TO STOP THIS AIR FLOW! but, I have no desire (read: wife says
no) to rip out the sheetrock and original H7 fixtures and rebuild my
entire ceiling. Plus, its too expensive.

SO, what can I do? I know they make Insulation contact rated remodel
fixtures, but I can't get the original fixture out of the ceiling. I
can remove the can itself though, but the frame and round bracket are
still up there. I thought of trying to take the can part of the
fixture out and put the airtite remodel version up there, but I don't
know if it will fit through the frame. Anyone have experience with
this?

Also, I see they make an airtite Eyeball kit, the 78PAT (for almost 30
bucks!) which has a gasket around it... perhaps using this airtite
eyeball to replace the existing non airtite eyeballs will help the
situation?

While I would love to get insulation up there around the cans, I will
be happy with just stopping the air loss. 30 cans times 3-4 CFM of air
movement is causing doors to move on their own.

Can ANYONE offer suggestions, or, preferably, EXPERIENCE stories on
what to do in this situation?

Thanks much!
