I do not know if this goes anywhere in your organization or not, but I used the green spray foam today, and it worked every bit as well as described by your materials.

I only needed one tube and one fan spray nozzle, as everything was in an open basement. Some grey blue/green gunk came out at the last of the tanks, and I just cleaned it up so all appears ok now. I also popped the trigger lock off so I could reach around with the gun and trip the trigger with one hand - works better that way and avoids delays of reaching around trying to unlock the gun.

I do have another three questions following a bit of background. I have an addition where the kitchen was built on sometime in the 1920's. That is an unheated crawl space and I have previously had the floor insulated. The addition crawl space is unheated and well below 50 degrees F until next summer.

My first question is which of your products do I want to spray on the inside of the unheated crawlspace concrete foundation and those rim joists?

I figure on just coating the entire concrete from the ground plastic cover up through the wood rim joists up under the fiberglass insulation.

Will there be any problem with the spray foam contacting the ground at the base of the concrete? Is it bug resistant in the event carpenter ants or termites ever were to gain access to the foam?

I am very happy with the results of the green spray foam in the basement.
