Attaching and Taping XPS for basement walls and floor
What is the easiest way to attach and seal XPS board to the foundation walls (interior)? We're building a new home with block walls. I plan on finishing the basement (eventually). I bought 1" 4'x8' XPS for the walls and three layers of 1" 4x8 XPS for under the floor. We'll be putting radiant heat in the concrete. The three layers was MUCH cheaper than buying 2" + 1".
Can I glue the XPS to the walls? Should I still tapcon? Should I tape the seams on the walls and floor? I"ll have the seams staggered for the floor. I planned to have 1" of XPS on the walls meeting the XPS on the floor, so the concrete would come right up against XPS on the wall.
I'll build a stud wall against the XPS with fiberglass. The exterior of the foundation has Delta MS without any insulation board.
