hi, i'm doing a music room in my house and i wanted to understand one thing i have a doubt about.
I want to create counter-walls with rock wool (10/20 cm) but I would like the structure to be rigid also to be able to hang lights, put switches.
usually rock wool is put on and then covered with a large fabric. aren't there alternatives that don't reflect the sound too much? the plasterboard is too reflective.
what do you think of wood wool panels?
I took a look at knauf heradesign or celenit
