extra layer of plasterboard
 

i'm installing a false ceiling in what will be a coffee shop. our
sitting room is directly above. so far we've put in a timber frame
with 100mm of acoustic rockwool flexi between the joists, there is an
airgap above that (150mm). above that the original lath and plaster
ceiling, above that is deadening, its a victorian house (no idea about
how in tact this is as in my experience lifting the floor when CH/
rewiring gets done a lot is removed), and finally floorboards (no
carpet)

i am attempting to take what *practical* measures i can to
soundproof. would an extra layer of plasterbaord be worth the effort?

also i'm confused about the fire rating. BC made no mention of a fire
rated ceiling when the plans were approved, however the ceiling does
seperate differnent "occupancies"... and what if we sold the shop or
house at a later date?

double layer of plasterboard - or not worth it?

It's one of the most cost effective 'sound proofing' methods.

I must admit to being surprised there were no fire reg stipulations.

I'd still double board for fire resistance anyway as someone will pick
up on it at some point.

You can get 15mm sound deadening plaster board (I got mine from Jewsons) @
£8 per sheet delivered, that makes a hell of a difference compared to normal
15mm board. Be carefull when putting up as is quite heavy compared to a
normal sheet. I used it when redoing the kitchen to stop sound passing into
the bedroom above.

It's one of the most cost effective 'sound proofing' methods.

If you go for it, do make sure that the joints are staggered versus the
first layer of plasterboard - would make a big difference.

Me too.

Worth it certainly in my opinion.

And if you want to go to extra expense lay fibre batts on the floor
above and 1/2 chipboard over that then ply on top again.

Don't overlook the importance of having solid doors as opposed to
modern crap egg boxes. I am assuming there is a doorway
interconnecting. Double doors will almost eliminate all sound.

But the double layer of PBd (use the pink fireproof stuff) is by far
the most effective single thing to do and probably the cheapest
option.

Good luck.
