I’m located in the Northeast and am building a 16’x32′ workshop. The floor joists are 2×10 PT 12″OC supported by piers at grade level. I’d like to lay Advantech for a subfloor and was wondering whether there was any advantage/disadvantage to laying a poly moisture barrier across the floor joists prior to installing the subfloor? I may eventually heat it with a woodstove. Any thoughts about Advantech v. T&G plywood? Thanks.
