Rock Wool. cut between attic joices or roll over

[rebelbuttmunch]

Hi,

Cutting Rockwoll with a saw in an attic just cant be fun. Do I get any benefit from rolling it out over the beams (parallel or perpendicular) or should I cut it to fit between the beams?

I don't use my attic for storage except for decorations and the odd bag of clothes.

Thanks!

standard practice is to fit between the rafters, then a 2nd layer over them
