Spray foam insulation odor


This past Monday, we had the rim joists in our basement sealed with spray foam insulation. They also added some blown in insulation in the attic. The spray foam is "open cell" spray foam and the attic insulation is borate based cellulose insulation.

The odor, we presume is from the spray foam, has diminished, but not yet gone away. It is lessening. We are running fans and trying to keept he air moving. Should I be concerned that the smell is still there? I broke off a piece of the foam that was sprayed on an area that is not exposed to the outside and held it to my nose and there was no odor. Any ideas?

Also, they originally were going to pump in the cellulose over our kitchen ceiling as we can feel a lot of air from the can lights we had installed when we did our addition. FOr logistical reasons, they could not get in there. However, they did suggest replaceing the cans with air-sealed cans. Any ideas if this works? IF so, any brands to use or stay away from?

Thankls

It should have been IC Air Tite cans.
I've used three differant brands and they all worked out fine.

The addition was done in 2003. Did they have air tite cans then? the cnas are IC rated, though.

Can I simply replace the trims with air tite trims? I saw that HD have them. I though about giving that a try.

Air tite cans have a safety device that shuts the light off if it over heats.
Do not use a differant trim ring.
