I was told by a salesperson at a pro lumberyard that one of the reasons their 7/16-in. OSB tends to be $1 to $2 more per sheet than the OSB in nearby big-box stores is that pro yards tend to stock OSB that's mostly made from hardwood strands, whereas the big-box stores' OSB tends to be made from softwood strands. He noted that OSB made from hardwood strands is stiffer, swells less when exposed to water, and is more decay resistant than softwood OSB. Is there really a difference, or is my salesperson blowing smoke?
