Can i run hardwood floor parallel to joists.

The most common way to lay install hardwood flooring is by aligning the planks parallel to the longest wall or run in the installation. Will this support new 3 4 t g running parallel to floor joist. The subfloor is tji joists with 3 4 t g osb glued and screwed. Older houses with 1 inch planks running diagonally to the joists can support flooring planks running parallel to the joists.

The flooring is 3 4 t g nailed directly to the floor joist. This is on the first floor the sub is plywood and the house has an unfinished basement. Hardwood floor installed parallel to joists what are my options to fix it. Just be sure to flatten the subfloors.

There is a steel i going through the middle of the house. Discussion starter 1 dec 31 2015. 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.

My question pertains to an upcoming job. Joist spacing will be 16 oc tji and subfloor will be 3 4 ply. The floor joist are rough cut 2 8 spaced 24 oc with a 8 span. 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.

3 4 plywood over joists 12 oc should be quite stiff enough. The span is about 14 feet from foundation. Flooring is tbd but will probably be either 3 4 hardwood or 1 2 engineered. If the subfloor is stiff enough there is no reason why solid nail down strip flooring can t be run parallel to the joists.

Apart from a few exceptions like sagging joists this is the preferred direction to lay wood floors because it provides the best result aesthetically. I believe the national wood flooring association recommends a glued 5 8 1 2 subfloor combination for a parallel application. First renail the existing plywood subfloor so that the old nails are tight and add new nails to achieve a maximum nail spacing of 6 inches. If the subfloor is a concrete pad these structural considerations don.

A flooring contractor howard brickman responds. 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.
