OhYah, you're going to be GLAD you had that done. Not sure how much COLD weather you get, but I'm betting the foam insulation investment will be particularly nice this summer.
Only thing left to do now is get the heat and AC in place. That along with a nice old comfortable recliner, perhaps a big screen in the corner and a refrigerator for the occasional adult beverage while pondering a perplexing problem

Good Job
