My whole house is built out of this. It's great, easy to drill holes and insulation is not needed, the walls end up quite thick tho. If you're just after sound proofing I think other materials are better for this, some foam probably.

You probably want panels of some kind.
I think the aeration just makes it lighter for manageability with a higher R value—regular concrete is probably more soundproof and comes in panels (like, for bathroom tile backer)

Just do the dense - visco-elastic - dense stack like everyone else, it's the standard for a reason. Dense can be concrete or brick or drywall or plywood. Visco-elastic can be green glue, mass loaded vinyl or rebond foam.

Not just soundproofing. Thermal too.
The idea is to go
AAC
Wood beams screwed onto the AAC
Insulation between beams.
Spacer clips
Drywall carried by spacer clips
Mass loaded Vinyl
Second layer of drywall
Seal air gaps with green glue

there is a few tours of sound stages on youtube and hanging a rug off the wall appears in a lot of sound stages.

Fuck no. Glass or mineral fiber wool is for that.

This. Mineral wool is absolutely superior for soundproofing and provides good insulation that cannot hold water.

breathable insulation is actually a good thing, it helps regulate indoor moisture and improve air quality. just don't use non-permeable paint/plaster on the outside because dew will form under it, freeze and make the whole thing crumble and fall off.

Not a problem in my area, bucko.

>>2991810
you still shouldn't paint over it with acrylic paint or other non-breathable shit because the moisture will accumulate in your walls instead of freely evaporating outside, potentially causing mold and not helping you regulate indoor humidity without relying on ventilation
