I suppose there is a good reason why I see professionals who talk about and demonstrate 1 part foam on Youtube when I'm searching for spray foam videos. I'm not sure what options are there. I'm currently looking at using 2" XPS and spraying the outer edge of the 'rectangle' of the rim joist, pushing the XPS into the foam and then foaming the XPS while its firmly held in place using some of the lesser expanding Great Stuff. Not sure if I should go for a pro kit but at this point it seems the cans are the best deal or I should have started with the pro stuff when I was foaming around the windows and doors when the bigger 'cost package' would have made more sense. Then again I'm not spraying a whole room so at this point it doesn't make so much sense to discuss it but I'm thinking ahead as far as 600bd ft kits go as far as making a small super insulated microhouse in the future.
