How do I frame a 2" (1.5") thick wall? [solved]

How would you put up/frame a wall where the 2x4 studs are turned flat to make the wall 2" thick? One especially tricky thing is that (it seems that) all nails must be toenailed since a 3.5" long 16d nail isn't long enough to attach the 3.5" tall plates to the studs. Are there any suggestions on how to avoid toenailing or how to toenail effectively with a nail gun so that they go in at the right angle to grip well, not split the 1.5" thick wood and not stick out the other side?

Non-standard framing techniques are usually not recommended for load-bearing or external walls. I would assume this is to go over an existing wall of some kind, such as a block wall in a basement? - Chris Jaynes 12 years ago
Correct. Over a brick wall just to add a thin layer of insulation and hang some cabinets. Must be careful to secure cabinets with more screws than normal since they won't be as long. - jlpp 12 years ago

If you're willing to put a little extra work into it, using screws instead of nails can really help make this kind of "light" framing much more durable. It's a little/lot more time consuming, depending on how much you love your power drill, but well worth the extra time, in my opinion.

Are the top and bottom plates already installed? Could you use a 2x2s for the top and bottom plates? Then you could nail (or screw) through from the outside of the plate into the stud.

Good suggestions. The plates are not installed so 2x2 is an option. Thanks. - jlpp 12 years ago

An easy way to complete a wall like you describe is to build it flat on the floor. That way you can screw or nail the studs to the plates through the plates. I recommend installing a separate plate on the floor or across the upper joists first. Floor usually works best. Then simply measure the shortest dimension from the floor plate you just installed to the joists and build your wall to that measurement less 1/4 inch. Now you can stand it up usually without the angle getting hung up on existing ceiling and walk it into place. If you don't use the extra separate plate, it is almost impossible to stand it up into place. Attach it to which ever plate (top or bottom) you installed first, then shim it to keep it stable and plumb it as you nail it to the bottom plate or the joists. When you build the wall on the ground, lay out your 16 inch centers etc. Flush up the second plate to the one you just marked and transfer the marks to other plate with a square. Now you know where to place the studs between the plates. This method is the most common practice for building non-load bearing walls in an existing structure and works with any size lumber you want to use.

Very cool. Thanks for the pointers. I'm learning a lot with these answers. - jlpp 12 years ago
+1 - This is not a bad way to do it. However, it can be tricky in a basement if the floor and/or the joists aren't exactly even. If you don't check your measurements carefully and plan ahead, you may end up with some pretty serious shimming to get things to fit. :) (In my case, on one very long basement wall, the difference between the longest and the shortest studs was about 7/8"!) - Chris Jaynes 11 years ago

I've done this before and typically I'll frame the whole thing with 2x2's (top & bottom plates + 2x2 "studs").

It can be tricky finding straight 2x2's though, so often I'll just buy 2x4s and rip them in half on a table saw.

Thanks, Eric. Do you just use nails to fasten? How many and how do you prevent the 2x2's from twisting? - jlpp 12 years ago
@jlpp - I just use screws, and usually I pre-drill first. Using a framing nailer will likely split the 2x2. As for preventing them from twisting, I assume you mean once they are installed (since you only have room for one screw really) I don't worry about it. Once you put drywall over them, they aren't going anywhere. - Eric Petroelje 12 years ago
+1 for ripping your own 2x2s. I read that advice before my first construction project, and thought it was crazy to do that much extra work. I went out and bought a couple of 2x2s and they were warped beyond use after just a few days (a week on the outside) in my basement. I haven't bought one since. It really is easier to rip your own. - Chris Jaynes 11 years ago

I would consider using tie plates with 8d nails. Perhaps T-shaped or triangular plates. Be sure to check your local building code.

Interesting idea. - jlpp 12 years ago

Use 2x2 top and bottom plates and 2x4 studs. Who care if the 2x2s are a lil warped... they're gonna be. Just straighten the wall as you nail it down or tapcon it or whatever then staighten the top to your line and nail to the joists or blocking. Done. No ripping anything.

I use 2 x 6 x 92 5/8" Doug studs (SPF or pregerably Doug Fir) flat at 16" o.c.
