This is because I accept glasswool in sound insulation wall constructions as porous absorption material primarily, a damping added to two parallel, dense and relatively easy vibrating surfaces... I don't use some other absorbing material for room treatment, different from one used for sound insulation... If gas flow resistance is acceptable (it is only relevant for me)... I will use same material in both cases... but I'm really off topic here ... with global industrial business interests... I'm aware of that... sorry.
