Question13
13. What thickness and type of insulation do I need in
a 50mm Knauf C steel stud partition at 600mm centres with 12.5mm
Knauf Wallboard on each side to achieve the Building Regulation
requirement of 40dB for internal walls in houses, flats and rooms
for residential purposes?
Installing 50mm of Crown Acoustic Partition Roll or 50mm of
Rocksilk Flexible Slab between the C studs would achieve a Sound
Reduction Index of at least 40dB.
