Installing a pine floor in a new addition. Boards will probably be 5-6 in wide. I am wondering how necessary it is to run the boards perpendicular to the floor joist. I would like to run them parallel. The sub floor is 3/4" T&G particle board with 4" of sprayed foam below. There is no basment below. If I don't nail the boards into the floor joist will it be a problem down the road?
