I picked up 10 sheets of ROSS at walmart today and began some testing. These are not scientific at all but observations of comparing the stuff.

ROSS Foam Board
Link to
Adams Foam Board
Same Size: 20"x30"
Same Thickness: 3/16"
Weight: Adams board 4.1gRoss 4.7g
Price: DTFB $1USD, ROSS $0.88 USD
Flatness: DTFB is wavy, ROSS is flat as can be.
Brightness of paper: DTFB dull white, ROSS bright white
Paper Quality: DTFB is ok and textured more, ROSS might have a thicker(heavier weight) paper and smoother finish.
Crush Test: (Pound a corner of a piece into the table). DTFB paper pealed away from the foam. ROSS paper held on to the foam and crinckled. See picture.
Paper Peel: DTFB peels clean and easy. ROSS pulls up the surface layer
Rigidity Comments: DTFB seems to be more rigid and prone to cracking and pulling the paper away for the foam around the area of a fracture. ROSS my be slightly less rigid and crease instead of crack.
Fold Test: Piece was fold 90degrees one way, then folded 90 degrees the other. DTFB paper started to lift and made a tighter radius bend. ROSS paper held on to the foam and had a larger outer radius bend
A&B style folds: Both are fine.
Foam Bevels with sharp knife: Both are fine.
Cold Water 1 min soak: DTFB seems to be affected more by cold water then hot water, the paper peeled very easily. ROSS was unchanged.
Hot Water 1 min soak: DTFB was slightly affected and the paper seemed to peel the same as it always does. ROSS was unchanged.
Suface water splash: DTFB "raised the grain" of the paper, similar to getting a piece of wood wet and the paper may peel a bit easier(hard to tell). ROSS has no noticeable changes.
Spray paint test: ROSS has a much smoother finish. DTFB paper becomes more saturated with the paint causing easier delamination. ROSS paper is still mainly white on the inside after painting. See picture.
Hot Glue Test
Paper to Paper: DTFB peeled the paper off, no surprise, ROSS eventually tore the paper off but it was much more difficult.
Foam to paper: DTFB pulled the paper off leaving it attached to the hot glued side. ROSS eventually tore the same but is was much more difficult.
Foam to Foam: This is the hardest joint to separate for both. I would consider it a tie.
Butt Joint: DTFB Pulled the paper off of the mating surface when wiggled left and right. ROSS held on great until to much force pulls the hot glue away from the foam edge. This type of failure is much easier to fix then the delamination of the surface paper.
