Specific changes relate to the New Zealand Building Code (NZBC) with regard to fire protection requirements. NZBC Clause C (Protection from Fire) has changed and Clause F7 has been amended. From April 2013, the old or new version can be used (installers should check which version they should be using with the specifier of the project).

What are the changes to Gib Fire-Rated Systems 2012?

1. Surface Finish Properties

The key change is a move from surface finish properties as determined by AS/NZS 1530.3 to a classification in accordance with ISO 5660 'Reaction to Fire Test – Heat release, smoke production and mass loss rate Parts 1 and 2'.

All unpainted paper-faced GIB plasterboard sheet materials now achieve a Group 1-S Classification. For paint or wallpaper finishes, contact the supplier of the finishing material.

This is relevant when applying for consent. Make sure you have the most up-to-date specification document from SmartSpec or Masterspec, as this will contain the change.

2. Steel Joist Systems

Steel joist systems have become more common in recent years. To assist with construction, the new book will also include recently tested steel joist floor/ceiling systems.

3. Garage Boundary Wall Details

New construction details for garage boundary walls are included. These now comply with the two-way stability requirement as specified in NZBC clause B1/VM1. The simplest solution is a change to nominally 140 x 45mm timber framing.

4. Text and Drawing Clarifications

The remaining changes relate to relatively minor text and drawing clarifications. This means that there has been little if any change to the majority of the specification and installation instructions.

Once you have the new GIB Fire-Rated Systems 2012 technical literature, check for any changes to the installation instructions, regardless of how familiar you are with the system.

Important reminders

Customised design solutions

The systems in the new GIB Fire-Rated Systems technical literature should cover most common situations where fire resistance is required. However, for special projects where specific performance is necessary, GIB Technical Services can assist you to develop a customised solution.

Beware of substitution

Different plasterboards react differently in fire. As such it is important that only the specified GIB plasterboard is used or that if a substitution is required, due to the requirements of a wet area for example, that only the following alternates are used.

 Penetrations in GIB Fire Rated Systems 2003

The Penetrations in GIB Fire-Rated Systems literature has stopped print. Generic details for the penetrations in GIB Fire-Rated Systems have now been provided in the main technical literature. A listing of proprietary penetration seals suitable for installation in GIB Fire-Rated Systems will now be available online only.

Since the penetrations section in the literature was last updated in 2003, there has been a steady growth in the number and range of accessories available for sealing penetrations in GIB Fire-Rated Systems. To ensure you have the most up to date information GIB has placed a listing online.
