Our 75 year old barn is in need of some new flooring for storage of household items up in the hayloft. The space I would like to cover is 16ft long, and 8ft in width. The true 2x8 joists are not perfectly spaced, but average between 26in and 29in in between them. I'd like to run 2x6 boards for ventilation, looks, and spacing, but the 3/4in plywood option would be much cheaper as I could get her done with 4 sheets. Would I be facing any regret with the plywood option?
