We purchased the Foam It Green Kit from their website *came with 17 free things, goggles, gloves, booties, Tyvek suit, lots of nozzles and fan tips*
The kit we ordered was for 1200 sqft and was $1500. Included four boxes (2 part A's & 2 part B's) the hose and mixing nozzle..and the above listed. If I didn't have three trash bags of overspray, that would have been enough for the ceiling, walls, and floor. Unfortunately, we were messy so we had to order a 200sqft kit (one small part a tank and one small part b tank)which was $400. So our whole project cost $1900 plus the $20 respirators we bought.
You can apply it between 65 & 78 degrees.there is a temperature strip on the tanks that let's you know if it's good or not. It wasn't super messy to clean up honestly. I'm living with a roommate friend and we are building in his yard, so I'm trying get to keep everything as clean as possible. The small crumbles just find a spot on the floor and will only pack more insulation under there. The medium ones almost the same thing. It did take up three large trash bags, but we're super light! Lol
It is closed cell foam and they sell thermal barrier paint for metal buildings. It cures in 30 seconds to 2 minutes. At least the door and Windows were open when we worked in it afterwards. Had respirators and all while foaming and didn't go in again for a few days. Seems good! Foam it green has lots of videos of how to do it (you have to watch these before you do it per instructions) it was super easy too. The tanks attack to a dual hose with two different color foam ingredients. They go into a mixing nozzle and is combined while you spray. One hose/tank is white the other blue. It comes out green.
They do a good job of showing how to do ceilings and walls. One inch is r value 27 I believe....their website has lots of info.
If you stop for more than 30 seconds you change the nozzle (they give you like 10) and add petroleum jelly to the nozzle (supplied) and trigger so it doesn't crystallize. I only stopped two or 3 times but we were prepped well.
