Polyester Insulation Option for GIB Noise Control Systems

GIB has responded to a large number of requests for a polyester insulation option in their GIB Noise Control Systems.

Having completed an extensive series of acoustic tests, they can now verify the properties required (density, thickness, and flow resistivity) of 100% polyester fibre insulation needed to retain the equivalent STC and IIC ratings to the GIB Noise Control Systems which have Pink Batt glasswool insulation specified.

It remains the responsibility of the specifier, supplier and user to ensure the product used meets all the performance characteristics set out and any other quality, durability and New Zealand Building Code requirements.

Full details can be downloaded from the latest GIB Noise Control Systems Supplement (September 2017). Or call the GIB Helpline on 0800 100 442.

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.

In the opinion of BRANZ , the GIB Noise Control systems, if designed, and used, installed and maintained in accordance with with the statements and conditions of Appraisal No.394 [2017], will meet the following provisions of the NZBC:

Clause B1 Structure: Performance B1.3.1, B1.3.2 and B1.3.4.
Clause B2 Durability: Performance B2.3.1(a), B2.3.1(b), B2.3.1(c).
Clause C3 Spread of Fire: Performance C3.4(a) and C3.6
Clause F2 Hazardous Building Material: Performance F2.3.1
Clause G6 Airborne and Impact Sound: Performance G6.3.1 and G6.3.2.

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.
