Hi, please can anyone recommend some batts etc. for sound insulation for a new stud wall seperating a bathroom and bedroom. Studs (2x4) are up but plasterboard not attached yet.
I have looked at
Lastly, are Resilient Bars and Acoutic Membrane (expensive) worth it?
Thank you
Have a look at Part E of the building regulations, it has examples of building sound insulating stud walls with commonly available materials
- more emphasis on decoupling each side of the wall than on sound absorbent material.
Now's the time to build a second stud wall not touching the first. Clad both in double thickness plasterboard. Fill with any of the less expensive sound insulation materials. You'll have adequate sound insulation between bathroom and bedroom even after a curry...
Thank you for the replies. I've trimmed the studs and moved them to one side of the 2x4 sole and header plates, and then inserted some more 2x3 to make offset stud walls. I now notice that I may have to connect noggins between the studs on one side of the wall to those on the other side. Will this spoil the sound insulation properties? Thank you
other, Fermacell prefinished wallboard (don't use two layers of plasterboard as Fermacell is superior) and rigid Rockwool batts
It will reduce the insulation. Can I ask why you need the noggins?
You'll live without noggins. If you want to stabilise against twist and distortion, a 45 degree piece at top and another at bottom, effectively bracing to the top and soleplate, will prevent twist if fixed solidly. It wont prevent warp.

Whether these are worth putting in I'm not so sure.

More hi-tech expensive 'solutions' where non is needed.
Fermacell costs approx 3 times as much as single plasterboard and doesn't give as good sound insulation properties as a double layer.
So if sound insulation is the priority and cost an issue stick to plasterboard.
Keep your poor comments to yourself. Don't respond to me.

But I'm sure you know you must be corrected when you give poor advice, dribble.
The noggins are for the toilet cistern and basin. Cheers
Any reason not to just fit them to the bathroom side of the double stud wall?
