Im about to order some Rock wool for Acoutic treatment and improvement.

I will use it for DIY Bass Traps and HF+HM absorbtion.

I remember that Ethan Winer said here that you should buy rigid Rock Wool with a density between 40kg and 90kg (per sqaure meter).

The insulation company around my corner sells:

60kg and 100kg.

Is 100kg even better or is it already too much??
Im just not sure if Ethan just gave a rough guideline and if "the thicker-the better" is the rule of thumb or if u actually should be within his given numbers.

Ethan, are u maybe here to help??
