Sprayed in open cell foam insulation fills all of the voids and minimizes any air leakage. It’s also superior for sound proofing for the same reasons, it leaves no place for the vibrations of sound to leak through.

Does the open cell stuff provide a vapor barrier? I seem to recall either open or closed cell does a better job but not sure which.

You are correct, open cell foam does not provide a vapor barrier. It does provide a very good air seal and is significantly less expensive than closed cell foam. Everything is a trade off. Closed cell foam is the Cadilac of foam providing great R value, great air sealing and a vapor barrier.

I found this article useful in a paper I am writing at university. Hopefully, I get an A+ now!
