What an awesome product. At 5" of closed cell spray foam in the ceiling and 3" in the walls, this structure will be sealed and insulated no less than twice as good as a typical 2x6 modern home. Jamin at Energy Lock Spray foam, seeing the value of the effort and desirous to help, gave an unbelievable deal! We did need to finish the scraping and cleanup as part of the deal. Joshy and Joseph enjoyed the novel job.
