Does shiplap installed on studs prevent racking?

Submitted by nivenhuh t3_y6svr7 in DIY

I’m creating a decorative wall and a fitting room and plan to install shiplap on bare studs.

The fitting room has three walls, with the bottom plate anchored into concrete. The decorative wall is an L shape, and bottom plate is also anchored into concrete.

The top plate of both of these walls are not connected to anything (because the ceiling in the room is a floating ceiling).

I’m planning to use finish nails to secure the shiplap to studs, but was wondering if that is sufficient to prevent the walls from racking? (Should I install plywood and then shiplap, or is that overkill?)

As long as you don't get skimpy with the nails, I'd trust it. You don't have wind or frost heave to account for.

You could install a 2" 20ga strap across diagonally both directions to help.

A dab of construction glue on the studs behind each board and that's permanent.

What is racking?

Racking is the term used for when buildings tilt as their structural components are forced out of plumb.

If you don’t secure the top plate and bottom plate of a framed wall, they can tilt in and fall over (racking).

While doing construction, you use a cross brace nailed from the top plate to bottom plate (and studs) to prevent this from happening.

Typically sheeting (drywall or plywood) is installed onto framing members, which prevents racking from occurring on free-standing walls.
