I'd like to soundproof the party wall in my lounge, but the problem is the front window recess starts a mere 50mm from the party wall, ergo putting in a new detached stud wall is out of the picture.
I'm also on a budget!
What I had in mind was to first put in some 37mm x 6mm deep timber battens against the party wall and plasterboard across the front. The gap would be infilled with fibreboard underlay glued to the wall (supposed to give sound & thermal insulation plus I already have a load left over from a laminate floor install at my last house)
This should give me some limited decoupling by reducing the contact patches for sound transmission. I'm even considering pre-drilling screwholes in the plasterboard and gluing a couple of washers to the underside to decrease the contact patch even more.
The plasterboard itself would be two skins of 12.5mm acoustic plasterboard bonded together with green glue - apparently this stuff is great but not overly cheap, hence why I'm attempting decoupling rather than green glueing both layers of plasterboard right onto the wall.
Opinions, alternatives or suggestions most welcome!
