Hi all,

What is the best material for noise-insulating a stud partition wall?
Simply stuff in some loft insulation or is there a better way?


You need decoupling of the two surfaces: thad means separate sets of
uprights for the two sides. They can be 'interleaved' but should not
be coupled. this stops sound transmission through the wood. i.e one
side's platerboard is fixed to one set of uprigths, the other side to
the other set. This is very importnat if yo uwant maximum isolation.

You need mass: each side should have a double thickmness of
plasterboard.

You need good caulking: fill around the edges to stop flanking paths.

You need 'loft insulation' inside to stop transmission through the
air.
