1. I would like to put the 2 inch rigid foam on the foundation wall, without the glue, but with fasteners like your foundation pins- but 3 1/2 inches long. Plasti-grip is one brand that comes to mind. Do you sell those? 2. Since the pink board is waterproof, can I just run my vapor barrier 1 to 2 feet up from the floor and use the seam tape to seal part way up the board?
