FoamBoard Research

Carlos_2 Member Posts: 9
Hello Wallies, I know there has been plenty of talk on The Wall between using insulating tarp and foam board. The question is, which foam board would you recommend in installing PEX for under slab aplications for radiant heat? 2" Pink board(open cell) or the 2" White (styro closed cell) and any comments you might have. Thank You
