My question pertains to an upcoming job.
Can i run hardwood floor parallel to joists.
One of the problems when running parallel is that if some joists are higher than others you get a roll in the floor lengthwise that makes the floor very difficult to sand and it can be seen.
The floor joist are rough cut 2 8 spaced 24 oc with a 8 span.
The subfloor is tji joists with 3 4 t g osb glued and screwed.
If the subfloor is a concrete pad these structural considerations don.
3 4 plywood over joists 12 oc should be quite stiff enough.
Apart from a few exceptions like sagging joists this is the preferred direction to lay wood floors because it provides the best result aesthetically.
If the subfloor is stiff enough there is no reason why solid nail down strip flooring can t be run parallel to the joists.
I have added 7 16 osb to the t g and plan on putting 2 8 blocking every 24.
Older houses with 1 inch planks running diagonally to the joists can support flooring planks running parallel to the joists.
I have a client that would like their 3 4 birch flooring to run parallel to the joists.
I have always installed hardwood flooring perpendicular to the floor joists.
Just be sure to flatten the subfloors.
Hardwood floor installed parallel to joists what are my options to fix it.
Joist spacing will be 16 oc tji and subfloor will be 3 4 ply.
There is a steel i going through the middle of the house.

The most common way to lay install hardwood flooring is by aligning the planks parallel to the longest wall or run in the installation.
The flooring is 3 4 t g nailed directly to the floor joist.
I believe the national wood flooring association recommends a glued 5 8 1 2 subfloor combination for a parallel application.

So my plan is to block the joists and replace the tired ugly flooring with something new run perpendicular to the windows but parallel to the 2x10 joists.
I have a 80 year old home.

This is on the first floor the sub is plywood and the house has an unfinished basement.
Flooring is tbd but will probably be either 3 4 hardwood or 1 2 engineered.
Will this support new 3 4 t g running parallel to floor joist.
