Thanx for your infos guys!
I have contacted my distributors and got these data:
Rockwool (I don't like the size of 1000x600mm, I prefer 1200x600):
Termarock 50 = ca. 55 kg/m3
Termarock 100 = ca. 110 kg/m3
RP-XV = 160 kg/m3
RP-X - ca. 90 kg/m3
Isover FDP: 50kg/m³
Heralan FP: 55kg/m³
The ones between 50 and 55kg/m³ are relatively inexpensive and the questions are:
Is 50-55kg/m³ enough?
If yes, should I go for rock or glass wool? How much difference would it make?
