    Hi

    What is the best insulation to use in the floor of our loft conversion?

    Are there minimum standards for building regs?

    Our building control officer doesn't seem to care to much but I would like to do the right thing for sound/heat purposes.

    Cheers

    200mm rockwool rolls will do just fine.

    Thanks Jord

    Is there any need to use chicken wire to support it?

    Presumably rockwool is the stuff to use in stud walls also?

    Cheers

    No chicken wire, just wedge it in before ceiling goes up. Can put it in a stud wall, but for sound reduction rockwool acoustic slabs are superior.

    You can also use a resilient layer on the joists, ie a strip of foam or rubber.

    Id say you'd need the chicken wire. The Rockwool you put in the floor for a loft conversion is for fire benefit. I had to put chicken wire in mine.
