@SteveH posted:Home Depot (including the one in Wappingers Falls, NY) stock a product similar to Advantech that's made by LP.
Yes, they sell mostly LP which is why I responded when Tom said Advantech was taking over the sub flooring industry that it depends upon where you live and that where I live it would have to be other brands.
They do stock Huber 7/16" 'Zip' wall sheathing and 5/8 'Zip' roof sheathing , but I am not familiar with them.
Thanks Steve,
