Whisperwall:

• Developed to provide superior acoustic properties with additional fire rated properties
• Interior wall construction

Double Steel:

• Generally used where two way FRR (Fire Resistance Rating), or superior acoustic performance is required
• Mainly intertenancy walls and corridors

Staggered Stud:

• Commonly used to provide effective resistance to sound transmission and acoustic impact
• Two way FRR

Double Steel and Staggered Stud:

• Recommended maximum wall height is 2700mm

Whisperwall:

• To achieve tested STC values install Pink Batts glass wool acoustic installation R1.8
• No SRP Continuous Nog Tracks or spliced SRP Studs to be used, doing so will compromise STC values
• Refer to GIB Noise Control System and GIB Fire Rated Systems

This is to certify that SRP Wall Products and associated componentry supplied by Steel Rollformed Products Ltd are designed to, and manufactured from, a compliant base material, to the relevant New Zealand / International Standards and to the relevant parts of the New Zealand Building Code.

In addition, all wall profiles manufactured by SRP meet the required BMT [Base Metal Thickness], strength and durability requirements. All wall component sizes and gauges manufactured by SRP are to precise specified requirements as established by design, and will not compromise structural integrity and/or fire/acoustic ratings of a relevant non-load bearing partition.

In particular SRP products are compliant as a minimum, with the following Codes, Standards and any referenced third party materials noted in this SRP Product Catalogue is current at the time of publication:

• AS/NZS 4600 Cold-formed steel structures
• Galvanised Coating Z275 to AS/NZS 1397
• NZS 3404 Steel Structures Standard
• NZS 3404.1 Steel Structures Standard — Materials, fabrication, and construction
• AS/NZS 1397 Steel sheet and strip
• AS/NZS 1170 Structural design actions
• NZBC — B1/VM1 and B2

SRP was established in 2007 and has been manufactirign and supplying to the New Zealand construciton industry since then.

In laboratory testing the SRP Whisperwall Stud Wall achieved an STC 52, STC 58 and STC 62 rating. Please visit the SRP website for configuration diagram, or contact SRP directly for a copy of actual Acoustic Test Reports (if required). SRP Whisperwall Steel Stud system provides significantly more Acoustic privacy than standard steel stud wall systems, or timber stud framing, of same size.

Whisperwall Stud is backed by a 50 year Durability Statement to demonstrate compliance with NZBC Clause B2-Durability, when used and maintained as described in the current New Zealand Steel Durability Statement.

SRP also offers a 10 year warranty across the product range.
