Air gap basement wall

[Bolian]

Hi.

I am going to install acoustic panels on my basement wall and would like tips on which battens to use for the air gap. I initially thought of metal battens, but they are a bit uneven so I wanted to use casing screws for easy adjustment. Composite... but it's quite expensive, and I haven't found good dimensions today. Or do I dare to use wood with a strip behind since the panel isn't sealed? Thanks in advance.

Hello.

I'm going to install acoustic panels on my basement wall and would like tips on which battens to use for the air gap. Initially thought of metal battens but they are a bit uneven, so I would like to use frame screws for easy adjustment. Composite... but it's quite expensive and today I haven't found good dimensions. Or dare I use wood with a strip behind since the panel isn't solid? Thanks in advance.

Can't you place metal washers closest to the outer wall as spacers in a wall screw behind a metal profile?
