hi guys, the rockwool (roxul brand) I used was 60kg/m3. very filmsy
I found out that roxul also sells 80kg/m3, 100kg/m3 and also 120kg/m3, rigid type. would any of those be good for making acoustic panel and bass traps ?
any help greatly appreciated
Any of them will work, it just depends on how you are making the bass trap. For panels that are 6" or less in thickness you can use the more rigid roxul. As the panel gets beyond that I would recommend the 60 or lower.
