• NZBC Clause B2 Durability: Under normal conditions of dry internal use GIB Fire Rated Systems have a serviceable life in excess of 50 years and satisfy the requirements of NZBC Clause B2.
• NZBC Clauses C1 – C6 Protection from Fire: GIB Fire Rated Systems can be used to provide passive fire protection in accordance with the requirements of NZBC Clauses C1 - C6.
• NZBC Clause C6 Structural Stability: In order to satisfy the requirements of this clause, designers must ensure that fire rated elements are supported by elements having at least the same Fire Resistance Rating (FRR). Collapse of elements having a lesser FRR shall not cause the consequential collapse of elements required to have a higher FRR.
• NZBC Clause G6 Airborne and Impact Sound: For many specifications in the technical literature Sound Transmission Class (STC) and Impact Insulation Class (IIC) performances are given. For higher performances, including those required by NZBC Clause G6, reference should be made to the current version of ‘GIB Noise Control Systems’. 

All GIB unfinished plasterboard sheet materials achieve a Group 1-S interior fire rating to NZBC C/AS2-AS6, Table 4.1, following testing in accordance with ISO 5660.1 and ISO 5660.2.

BRANZ Appraised

Noise control plays an important role in office comfort, productivity and privacy/confidentiality. Studies show that a positive environment has a positive effect on business. Attention needs to be given to noise control, room acoustics, and services. Open plan offices require a degree of privacy which is achieved to some extent by masking sounds. Senior managers expect more noise control and require it for confidentiality. Seminar and meeting rooms, and walls between tenants need to protect the amenity value of users. Wall penetrating ceilings will provide a higher level of performance, thus making GIB Noise Control Systems the perfect solution.

Other areas requiring attention are those that endure noise disturbance from neighbouring rooms (adjacent, above or below) in the form of airborne sound from TV and voices, impacts from footsteps along corridors and stairs, or services like showers and toilets. Noise from impacts travels horizontally along floors as well as up and down; impact through walls can be a concern where there are no buffers from wardrobes or bathrooms.

Noise from lobbies, entertainment and conference rooms can require special attention as well.

Protection from external noise is important near main roads and airports, while room acoustic treatment around receptions in large foyers can aid intelligibility.

GIB Noise Control Systems are ideal for use in such situations.
