First off, big thank you to the people that asked how to insulate a crawlspace, already and an even bigger one to those that answered. It was all very informative and answered a lot of questions I had. It seems, that general consensus is to use the rigid foam insulation on the walls, instead of stuffing fiberglass into the floor joists themselves.​My question for you all is, what do you use to affix the rigid board to the walls? Is it a form of glue or nails / screws? I see there is a particular tape you use to cover the seams, but I am not seeing any products to secure it in place.​Thanks in advance for the help! via /r/DIY https://ift.tt/3sQb4Cv
