Biform composite decking has been formulated especially for New Zealand and Australian high UV conditions. We have backed this up with extensive testing by the Building Research Association of New Zealand (BRANZ) in conjunction with CSIRO in Australia. This testing includes accelerated weathering, UV xenon arc exposure (equivalent of 15 years) and testing of quality control systems throughout the whole supply chain.

Here at BiForm, our BRANZ Appraisal No. 680 [2015], is something that we are proud of, and being the only BRANZ appraised Composite Decking on the market, it is another thing that sets us apart. After rigorous testing, our eco decking was given the BRANZ Appraisal. We have held the Appraisal for over 5 years.

As New Zealand’s leading supplier of composite decking, BiForm is pleased to offer our transferable 25 year limited warranty.

After 15 years experience with our product in New Zealand’s high UV and high relative humidity conditions, alongside our robust testing, we are confident in offering our customers this peace of mind.

Fire testing and ratings for building materials are extremely important. Projects will often come to a halt if certain materials don’t meet NZBC requirements for fire safety.

To ensure a streamlined specification, BiForm had their solid composite decking fire-rated and now has this information readily available for architects.

It was found that BiForm’s rating of 5.7 k/Wm2 exceeds the Building Code requirement considerably.
