Insulation for partition walls

[Arnold9801]

When I made wooden partition walls on our house 23 years ago,  I used fibreglass insulation inside them and then covered the partitions with chipboard and plasterboard.

 

I'm now doing a new build which will have a lot of wood partition walls upstairs. I would prefer to avoid using fibreglass insulation this time and was wondering about getting the gaps inside the walls filled with this paper fibre (if that's what it is?)

 

Has anyone else used similar?

Is this for soundproofing ..? If so you need to use acoustic fibre insulation and an air gap. It’s a standard detail for sound control.

No it's just for general insulation.

Isn’t sound insulation the only useful type of insulation on a non external wall?
