I'm building a new house and my floor joist are running the same direction that I want to run the wood flooring, can I use 2" x 4" sleepers every 16 inches between the floor joists & nail the 3/4" tongue & groove boards into them? I would prefer to do this rather than installing another level of sub-flooring.
Hello, this is my first post. Hope I can help everybody.
Is there a reason you don't want another layer of subfloor?
Are the joist 16" o.c.?
It is best practice to run hardwood flooring perpendicular to the floor joist, but it can run parrallel. Assuming you have a 3/4" subfloor. If you are concerned with cupping between the joist it would be best to upgrade the subfloor size. Use a high quality plywood (not osb) maybe 1" instead of 3/4" or if the subfloor is already glue and screw down 1/2" to the current 3/4". Also make sure the subfloor is glued to the joist.
