Hi all,
I am embarking on a studio project soon, which I have drawn up but haven't figured out how to upload yet!
Anyway,
I am wanting to know the stc rating of 4inch concrete blocks, cavity and then an inner wall of concrete blocks?
Will it be any good?
or would i be better with 4 inch concrete block, cavity and then a stud wall system with double gyproc on the inside sat on rc?
I have searched the forum and only found one thing similar.
Please help!
stc values
