Staab, apart from the theoretical questions, rest assured, it really is not critical, and 40KG will definitely work if you just want to get on with it.
The 40kg/m3 would definitely be better, the air flow resitivity 100 kg/m3 is significantly higher than 40 kg/m3 material. The resistivity increases much greater than a linear relationship.
