Eco Brooklyn actually uses a lot of Great Stuff can foam. The cons is that we use up a lot of cans and it is petrochemical foam with all the chemicals and environmental issues with that. The pros is that as far as spray foam goes, the cans are actually the least bad. The DYI "builder packs" you can buy over the internet are really bad. The other option is the professional grate set-up which costs thousands of dollars and isn't much use for weather sealing and old house. They are just overkill and IMO are only really useful for new construction (=bad). Some might say you can use it for sealing an old house but in almost all the cases I have seen you can do it with cellulose which is much greener.
