Rockwool loose lay?

[Jack07]

Hi,

I was looking for some insulation to fill internal stud walls, between floors and some of my loft.

My mate has very kindly given me some rockwool. On closer inspection of the packs they are rockwool energysaver. Apparently this is designed for blowing into cavities using machine.

If I can get it to stay in the stud partition while I board it would you think this is suitable? Obviously slab/roll is easier but was wondering if this stuff will do all the jobs I require?

Any help will be greatly appreciated.
Thanks
Jack

You need acoustic and maybe fire insulation , and that stuff you have will be useless
