Hello,
I am considering adding sound insulation to my attic using stone wool. Currently, my attic consists of mineral wool, a vapor barrier, and drywall. Would it be possible to lay a layer of stone wool on top of the existing mineral wool and then screw wooden boards over it to make the whole structure more compact? Would this be effective? Pictures are attached.
Regards, Theo

see above. I just edited my post as you replied... Sound is tricky... measurements can also show that the sound is transmitted through the facade, not the roof The sound comes from the ceiling and walls. I also had some of the walls additionally double-layered afterwards.
Now my question is whether it would help to add mineral wool over the existing mineral wool to make the whole assembly a bit denser.
Gypsum boards are available in standard, green, or blue varieties. Blue boards are designed for sound insulation, and there are tables for wall assemblies and soundproofing. In cases of extreme noise, using two blue boards stacked in 12 or 15mm (½ or ⅝ inch) thickness can be effective. We used this solution in the flight path area near Tegel.

If noise is a major issue, using two blue boards in 12 or 15mm (1/2 or 5/8 inch) thickness stacked can be effective—
we had this setup near the flight path of Tegel Airport. What did you use the boards for?
Ceilings or walls?
Do you also have a prefabricated house?
