Question12
12. What thickness and type of insulation do I need in
a 63 x 38mm timber frame partition with studs at 600mm centres and
a layer of 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 timber studs will achieve the
40dB requirement.
