Hoping somebody here might be able to help! (Have done a search under soundproofing/insulation but havent found the answer I'm afraid!)
We are trying to improve sound insulation (as its non existent!) on the party wall of our semi-d which consists of a cavity block with a regular plasterboard (and no insulation) stuck to it.
The plan is as space is quite tight, to apply a layer of acoustic membrane to the existing plasterboard and then double board it with staggered sound boards and fill the pillars and into the ceiling with acoustic rated expansion foam.
(we have looked into packing with rockwool and then double boarding but space is a real issue so trying to minimise the loss of space is also a priority!)
But my problem is I have not been able to source a reasonable type of acoustic membrane roll and I wonder if anyone has used such a product, or knows of a good substitute or indeed a supplier either online or in the leinster area (have tried alot of the builders providers in Dublin and am also waiting for an email back from atil)
This is the only place I've found it so far but its fairly steep at £180 per roll + delivery etc

Appreciate any info if anyone has experience of this type of product!!
