My local Home Depot sells 2" pink rigid foam insulation sheets which is so popular with this forum's users, but my local Lowes only sells 2" green rigid foam insulation sheets. They appear identical except for color, but are they? For model railroading purposes of using foam insulation sheets for track underlayment covering a bench work's plywood decking, do they work equally well at deadening sound track noise? Do they work equally well for carving, cutting, and creating land formations? Do they take paint equally well? Does either the green or pink have any obvious and real advantage over the other for model railroad use? I would likely go with the pink foam boards except I'm making a small 4x4 z/n gauge layout. Unforrunately H.D. doesn't sell 4x4 pink sheets but Lowes does have 4x4 green sheets. I need advice. What do you think?
