[QUOTE="Timber_MG, post: 975103, member: 18"] Locally manufactured rockwool is typically less flow resistive to imported grades, so some imported grades (notably isover) are sometimes sold at a lower density than what might be marked. Glass Fibre is typically more flow resistive than rockwool, so one can use a lower density grade. Specifics are very hard to come by as testing for this parameter is seldom conducted as the primary use is as insulation and not for absorption. [/QUOTE]
