IPL Flooring & Roofing is manufactured in accordance with AS/NZ 2269 Construction Plywood. The panels are to be installed in accordance with the building design code. 

In New Zealand, the maximum joist spacing for 19mm F8 structural plywood is typically 480mm. This spacing is recommended to ensure adequate support and to comply with NZS 3604:2011 standards for structural plywood applications. This spacing is suitable for applications such as flooring and decking where the plywood serves as a structural element.

For 19mm F11 Structural plywood in New Zealand, according to NZS 3604:2011, the maximum joist spacing is 600mm. This spacing is appropriate for structural applications such as flooring and decking, where the higher stress grade of F11 plywood provides the necessary support for larger spans without compromising structural integrity.

For comprehensive details and to ensure compliance with all relevant standards, you can refer to the full text of NZS 3604:2011, which provides extensive guidelines on timber-framed building construction in New Zealand. You can access the standard through the Standards New Zealand website (Standards.govt.nz).

The Engineered Wood Products Association of Australasia (EWPAA or PAA) audits the production processes and internal quality control procedures to ensure we meet the requirements of the product Standard. This third party audited, process based, quality assurance scheme meets the requirements of an ISO Type 5 system and ensures constant monitoring of maintaining production of quality.

All veneer used in IPL Flooring & Roofing is from renewable, plantation-grown Pinus Radiata New Zealand plantations.

All IPL construction plywood is bonded with phenol formaldehyde resin (dark red in colour). This results in a permanent bond which after manufacture will not part. This is the same bonding material used in Marine type plywood. 
Formaldehyde emissions in IPL plywood are very low and rated as Super E0 - less than 0.3mg/l AS/NZ Standard 2098:11.
