Compliance Statement
Scope of Use
The SRP Whisperwall stud has been developed and manufactured to provide superior acoustic properties in interior wall construction, up to Max. Height = 3.6m (0.55BMT) or 4.2m (0.75BMT).
SRP Whisperwall System provides significant advantage over staggered stud in ease of installation and better acoustic results. Also significantly increases acoustic (STC) performance vs Standard steel stud partition walls.
The SRP Whisperwall System requires a special 2-pc split-nog track - as opposed to standard (1 pc) continuous Steel Nog Track - in order to maintain/ maximise Acoustic (STC) performance.
New Zealand Building Code (NZBC)
