It seems Paroc has removed that information... I found the following link to Rockwool:

If you stick to mineral wool (thus avoiding glass wool) you'll probably be on the right track.

Ok, mineral wool in about 95mm then maybe?

Ask again:
Some beams look like this, that is, quite cracked... Does it matter? Here you can also see the blind floor and batten. (In this case, boards)

No, the cracks have no significance in this case. 95 mm will be fine.
