*Cardboard*? Are you joking? I thought that junk had gone the way of teh dinosaurs. I saw it being used on townhouses in Maryland in the 80's - the stuff started to warp and fray (i.e come apart) even as the places were being built. Chunks would fall off the corners. OK< so they had a type of gum-wrapper-thin metal flashing on one side. Big deal. That also started to peel off even as the complexes were being built.
Just an "FYI".
I don't know whether plywood has a higher R value than does a solid piece of the same dimensions; I know that one of my woodworking books lists at least some info re: the R-value range for wood, want me to look that up? The info is for solid wood. I don't know where to find that info re: plywood, unless it's somewhere that Google (etc.) can find it.
HTH...
