Okay, so I gave my Tri-Ply/foam sandwich a try. Went with 2 inch foam for rigidity. Glued leftover pieces of Tri-Ply to each side. I figured the Tri-ply gives screws something to bite into and seeing Dallas Joseph's post about shorts and foam I think it was the right choice instead of gluing anchors into the foam whenever I need to screw something down. The sandwich isn't as light as I had expected but I believe it is stiff enough that I won't need a frame. It'll just lay on top of an old folding table. Cleats in all 4 corners to prevent

Joe,

I am not familiar with the term "Tri-ply" (except maybe for stainless steel).

Is it 5mm underlayment?

Thanks,

John
