Questions: Can I run the floor parallel to the joists since I would have at least 1” of subflooring? My concern is that the floor would look better if I had the long runs connecting the living and dining room. The longest dimension is through the living room to the foyer.

Also, should I start with a row away from the wall sufficient enough to connect two rooms together? From this row, work in two directions. This would mean installing a “double” tongue. How would I create this double tongue?

Thank you,
KEvin

You can do as you wish, it is your home after all.

It is always a good Idea to install across the joists. 1" is pushing it to go the same direction as the joists.

The gentleman expert has replied. His responses are the most expert here. Across the joists is the best. Go to www.nofma.org (http://www.nofma.org) and click publications and the publication on installation and download for free to learn about subfloor prep, acclimation, installation, etc. Double tongue requires 'splines,' and these are often offered by manufactures or local DIY store. Some installers manufacture their own by stripping flooring or by stripping paint sticks and inserting. Solid hardwood flooring is recommended to be installed across joists for support. We've had many posts where posters report that they have beautiful hardwood floors that sag between joists. Do not make an expensive mistake. Do your research and heed advice.

Man, you guys are awesome.

Thank you for the replies. I think I am going to run perpendicular to the joist even though I am going to have either 1 3/8" or 1 1/2" subfloor. It appears, according to NOFMA, that 1 1/4" subfloor is acceptable, but not ideal if you want to run parallel.

thanks again for the wonderful advice. I am getting ready to remove my current particle board layer, and replace it with either AC or BC 3/4" plywood. Is there any advantage to using AC over BC as a layer on top of subfloor?

AC or BC are both good. It's your choice.

With 1-3/8 you should be good to go any direction you wish.

Is it necessary to apply plywood over particle board subfloor??

It is necessary to remove the particle board and burn it!!

My bad, not particle board... I checked from the basement and it is a plywood. It is stamped with the following information if this makes any sense:
TECO tested
PS 1-S5
Exposure 1
24O.C. 23/32 Inch
Mill 272
I would assume since it is a plywood, it is ok to use as subfloor, and would not need any additional ply layers. (so long as it is nice and flat surface.) If the above indicates it is not acceptable, let me know. Thanks!
