Redoing damaged floor - what thickness insulation to buy??

We recently had to take up our living room floor after damage from a leak - it turned out to have loads of layers (thick wooden boards over plywood over plasterboard over insulation over chipboard), I am currently trying to get the materials back together for relaying everything above the chipboard but I don't really know what to do about the insulation layer.
It appears to be a kind of green fibreglass fluff similar to the kind you would get in a loft, but I don't really understand how such a soft material had all that heavy stuff (oak and plasterboard and furniture!) on top of it without compressing completely, it seems to be about 2.5cm thick underneath the plaster.... what thickness should I buy to account for it being squashed down?
Sorry if this doesn't make sense - I can take a photo if it would help but not sure where to post it!
EDIT: I think this stuff might be 'acoustic partition roll'...?
