What does these figures actually mean?
This material was named by Paroc representative when I asked about rigid wool/fiber slabs which had density around 40-50 kg / m^2 although the guy could not give any ideas how the material works in acoustical sense.
I'm just looking for cheaper options than real acoustic rigid wool/fiber which is very expensive. I was thinking of putting these inside larger panels and use real acoustic (3,5cm think with fibreglass cloth) slabs, which I already have, as surfaces.

So... Did you buy something???
What's the solution for acoustical treatments in FINLAND???
Can it be this difficult, PERKELE!
