If you give them a ring they will send you the Orange Book and this will give you all the construction techniques for various applications, Fermacell boards are very dense and are designed for soundproofing and fireproofing, i am using it in my house, if you are doing it yourself you can request one man boards these are 1200 x 1200 and relatively easy to handle, also the panels are glued together when you install them and it makes a crackin job.
