GIB Fire Rated Systems have been appraised for use as fire-rated load bearing and non-load bearing framed constructions elements in buildings.

• 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.
