Well, I have to spec a new downstairs toilet stud wall for building regs. This is my first "controlled" stud wall ;-) Its going onto an ammended full plans, which must pass. I want to keep the wall thickness to a minimum. So ... From part E, I need 75mm timber stud, plasterboard at 10kg/m2 (12.5 echeck board or somesuch), and suspended mineral wool inside at 10kg/ m2, at least 25mm thick and suspended. Whats the deal with "suspended" ? Do I get out the sewing machine ? Can I use more mineral wool and standard 12.5mm PB ? Any other requirements for a toilet room wall. Any special requirements for the door ? (must let in air for the fan, so whats the point in the super wall and a leaky door) Thanks, Simon.
