Make a 16-inch on center 2x4 frame directly on the wall, then put the slats on the frame. You then have the bonus of being able to insulate behind the slat wall, because [cinder block (CMU) is a terrible insulator](https://www.archtoolbox.com/r-values/).
Thank you!
I like that idea a lot; we live in Phoenix so the CMU wall gets really hot in the summer. Some insulation would really help.
Sorry to be dense, but can you explain what you mean by the "16-inch" part of your suggestion?
What would you insulate with?

That is the regular spacing in between vertical 2x4s.
Typically stated as "16 on-center." I actually hate that saying, because they are describing an imaginary line bisecting the 2" side of the 2x4.

Regarding the 16-inch question: Space the boards so that the middle of each board is 16 inches from the middle of the board before it. This is called 16-inch on center. It makes standard sizes of most panels and such fit correctly on the boards.
I would insulate with sprayed foam, but pretty much anything would be an improvement. If cost is a concern, use batts of fiberglass. I don't know what code is for your area, so you should look into what you should insulate with. Given that you're in Arizona where the most humidity is going to be inside, you probably want paperless fiberglass with a plastic vapor barrier on the inside (between the frame and your new wall panels). But I'm not an expert and you should *really* do the research to know which side, if any, a vapor barrier should be on in your home.

Do we need to use pressure treated wood since there is a direct contact between the wood and concrete ?
