the flite test waterproof foam board is 117 grams for a 20" by 30" sheet or 28 grams per sq foot.
depron 6mm is 171 grams for a 27.5" by 39" sheet, 23 grams per sq foot.

A typical wing+tail for me is 2-3 sq feet total, so diff is 10-15 grams heavier with this board.
Since this weight is more toward the tail, they might require maybe 2-5 grams more nose weight and then paint weight since the board needs to be painted since it is brown. If you design something from scratch you can optimize wing placement to avoid the nose weight increase.

So an increase of .5-.75 oz total approx. compared with a an indentical depron setup. With a an original wing loading of 6 oz/sq foot, it isn't much of an increase.
