Is using spray foam from a can really "best practice"?
I work for a weatherization company and we use a lot of spray foam cans to air seal these old leaky houses. Fortunately my company also cares about using the products and techniques from a sustainability perspective. I have heard that SPF cans are fairy bad for the environment, but have they do such a good job of air sealing.
My question is: What are the drawbacks of the SPF cans and are the "green products" (like OSI Green Series Pro Foam ii), any better? Is there a product that does the least amount of harm in any significant sense?
Any help would be appreciated and the more detail the better. Thank you.
