Update on XPS Installation
I read the countless XPS questions throughout this forum but was just wondering what the best/latest way of installing XPS on the concrete walls. I have 7.5 ft poured concrete walls and bought 1" XPS T&G foam board for them. I read to buy PL-300 for adhesives but thought that would be enough. After reading many posts, they say also to use fasteners/anchors/1x3s. Is this necessary? Also after watching Holmes on Holmes install XPS they seem to overkill it. Do I need to spray foam the whole perimeter of the XPS and then tuck tape it also? Does the XPS have to be lifted off the ground when installed? How much glue is needed on the back of the XPS? Do they sell PL-300 in gallons instead of buying the individual containers? Thats alot of XPS talk here. I appreciate any advice.
