Structure & Wall Height

Used in conjunction with framing that complies with NZS 3604:2011 will meet the requirements of the New Zealand Building Code. Studs are at a maximum of 600mm centres - dwangs are not necessary for effective bracing but may be required for linings or claddings.7mm DD IPL Bracing Ply™ is structural plywood manufactured to AS/NZ 2269:2012. It is suitable for design of earthquake and wind bracing for timber framed buildings in accordance with design codes NZS 3604 or NZS 3603 andAS/NZS 1170. Use section 5 of NZS 3604 when adjusting bracing capacities for walls of varying heights. A part sheet can be installed above a full sheet, in this instance the part sheet must be nailed off using the same pattern as standard full sheet.


As IPL Bracing Ply™ is an integral part of the building structure it must be durable in each application i.e. have at least 50years durability rating. In interior dry applications (i.e. 18% moisture content or less) untreated IPLBracing Ply™ is acceptable for use. However, in applications where IPL Bracing Ply™ may be subject to wetting, dampness or condensation (basically where potentially the moisture content may exceed 18% for prolonged periods) IPL Bracing Ply™ must be preservative treated to at leastH3.2 hazard rating and fixed with non-corrosive fasteners (i.e.stainless steel or silicone bronze).

Exposure during construction

IPL Bracing Ply™ will withstand rain exposure for at least 3 months.The possible wetting may causes light buckling of panels but generally, after drying, there is close to full recovery and structural values will be retained.

Installation, Sheet Fasteners and Connections

IPL Bracing Ply™ is to be installed and fixed as per the building design, technical literature and safety data sheets. As plywood dimensions can vary with changes in ambient humidity and wetting during construction it is recommended to allow expansion gaps between adjacent panel edges of at least 2mm. The minimum fastener requirement for7mm IPL Bracing Ply™ is 50mmx 2.8mm dia hot dip galvanised flat head power driven or hand driven nails. In sea spray zone D, stainless steel annular groove or ringshank nails must be used. For bottom plate hold downs refer to GIB HandiBrac® installation instructions for correct installation and bolt types to be used for concrete and timber floors. Ground clearance must be as specified inNZBC Acceptable Solution E2/AS1.


IPL Bracing is manufactured in accordance with AS/NZ 2269. All sheets have IPL construction details/NZ standard/plant number and name on rear of sheets.The Engineered Wood Products Association of Australasia (EWPAA) audits our production processes to ensure we meet the requirements of the productStandard.
