Hi,
I am converting a double garage in to a Lounge (habitable space) and a study (technically non habitable). The dividing stud wall is classed as an external wall and hence it's construction has been agreed with Building Control as:
12.5mm Plasterboard, 18mm OSB, 160mm cavity (with 200mm acoustic insulation), 18mm OSB & 12.5mm plasterboard. The 160mm cavity is actually two stud walls sharing top and bottom plates.
I have the wall constructed with the lounge side left to plasterboard. I'm using taper edge plasterboard which won' be plastered.
Can anyone advise whether it would be beneficial to plasterboard the lounge side with 12.5mm soundbloc board or will it not make too much difference?
Appreciate any comments,
Regards,
Peter
