Their's quite a bit of difference actually. It's made of entirely Douglas Fir or Western Larch. It's graded B or better where Ext. Plywood is graded in the C range. Knots and knot holes..It can have knots but NO knot holes and comes sanded. Waterproof adhesives, thickness of layers, and the use of a sealer..... TOP SHELF of the PLYWOODS....$$$$$$$ !!!!!
