Hi,
I'm developing 2 flats in a 4 story building. The sound consultant has recommended the following sound wall lining to pass the sound flanking tests
25mm air gap
50mm stud filled with soundproof insulation
2 x 12.5 soundbloc board
Plaster skim
This is a big cost item in both materials and labor....does anyone know if this is all needed or could a different (cheaper!) solution be used?
