The Alucobond A2 Tray Panel System meets all NZBC requirements for commercial cladding, including for buildings over 7m high.
In addition to BRANZ ISO5660 testing, Alucobond recently had “intermediate scale fire testing” conducted on their Alucobond A2 System. The NFPA285 testing was performed on a wall build-up common to New Zealand construction, to give specifiers confidence when designing with the Alucobond A2 system.
The system tested
The test specimen comprised a structural wall frame constructed of 90mm timber framing with GIB plasterboard on both surfaces. The frame cavity was fitted with glass wool thermal insulation.
The outside of the wall frame was covered with a water-resistive barrier and Alucobond A2 cladding. The Alucobond A2 panels were fixed with Alucobond Tray Panel System extruded aluminium profiles and support rails.
The cavity between the Alucobond A2 and the air barrier incorporated rock wool and stainless steel fire barriers.
This wall system passed the NFPA285 testing which involved exposure to two gas fires for a total duration of 30 minutes.
The Alucobond A2 Tray Panel System requires no sealant in the joints and provides a long-term low maintenance cladding option — as would be expected of a system designed to safeguard a building against the environment and potentially fire.
