Hi there,
We’re considering an off the plan apartment and have asked the builder for wall specifications in terms of soundproofing levels, we’re primarily concerned with noise travelling between another apartment. They have advised the following:
Intertenancy walls are Rw/Rw+Ctr 60/52
Internal walls to corridors/terrace Rw/Rw+Ctr 55/50
Apartment /external Rw/Rw+Ctr 56/46
Was hoping for some input on whether these are “good” levels. I think the BCA minimum is RW + Ctr 50, so interested to see how a 52 is in comparison. Also I understand there are other factors at play with sound travelling, but keen to get anyone’s input or opinion on above. Thank you.
