No personal experience with the spray foam, but would think you should be ok provided the housings are IC rated. Perhaps a phone call to the insulators is in order.

Pitboss:

I called the lighting manuf today of the pot-lites (IC) rated. They said absoutely no to if i can apply spray foam insulation directly to the pot lite can. Yes if i build a box around the can with the proper distance from the rear of the can. Pink fiberglass or equivalent is also ok.

Hi Fred,
There is another listing that is desirable along with ic if these are in an insulated area, air tight. If the cans are not air tight, you will be venting conditioned air into the insulated space.

Get some polyisocyanurate foil-faced board and build the box. Use foil tape on the seams and then you can foam around the box. This will make an airtight installation and still keep the foam from the fixtures.

At least one reason for not foaming the fixtures directly has to do with the possibility of one day wanting to remove the fixture for some reason.
