I'm building two stud walls joining at a right angle to create a small room in the corner of a larger room. The timber I'm using is 63x38mm (2 1/2" by 1 1/2" - actual measurement) CLS. One wall is 2.4 m long, the other wall with the door is 1.8m long.
Now looking at the soundproofing solution I have in mind I wonder if these studs will be strong enough to support the wall. Can anyone advise on the strength of such a structure with 40 or 50cm centres? The walls are not loadbearing.
Heaviest case, the wall layering will be: Soundboard | Stud wall (40cm centres) | Soundboard | Rubber panels on which are suspended: | Soundboard | Soundboard
An alternative layering would be | Soundboard | Stud wall (50cm centres) | Rubber panels on which are suspended: | Soundboard | Soundboard
The soundboard is heavy sound resistant plasterboard which weighs 28kg for 2.4m by 1.2m.
The rubber panels weigh 15kg for 1m by 1m
