IMPORTANT INFORMATION FOR BUILDERS AND INSTALLERS

The recent revision of NZS 3604:2011 has resulted in some changes to

the methods used for designing and installing GIB EzyBrace® bracing

elements.

Full information relating to design and installation of GIB EzyBrace®

bracing elements are provided in the publication GIB EzyBrace®

Systems May 2011.

KEY CHANGES

• GIB EzyBrace ® 2011 systems requiring GIB Braceline ® can now be

fastened with 32mm x 6g GIB ® Grabber ® screws.

• The corner fastener pattern now requires 2 additional screws

to each corner of all bracing elements.

• Ceiling diaphragms are now limited to 12m in length.

Any 10 or 13mm GIB ® Plasterboard lining may now be

used for ceiling diaphragms.

Information relating specifically to the correct installation of GIB EzyBrace® bracing elements

will be provided in the next reprint of the GIB® Site Guide. In the meantime they are provided in

this publication. These pages replace pages 52 – 54 in the GIB ® Site Guide Jan 2010 when

installing GIB EzyBrace ® 2011 systems. Projects designed using GIB EzyBrace ® 2009

systems still need to be installed using those system requirements.
