As someone else pointed out, I dont really need soundproofing come to

single skin stud would be effective.

I wouldn't... you say security is a concern: if you consider that there's
a risk of a scrote breaking into your neighbour's house and climbing up
into his roofspace in order to enter your house, do you think a couple of
sheets of plasterboard will impede his progress for more than a few
seconds?!

Yes.

Also, I don't know how big your loft hatch is but that might well be an
issue when it comes to taking sheets of plasterboard up there; at least
you're going to be restricted to using small bits only.

Good point. Probaly best to use blocks if they can be eaily taken up.
