• AliBat can be used in conjunction with non-combustible exterior cladding products to form a non-combustible cladding system compliant with the provisions of NZBC Clause C3 — External Spread of Fire
• As such, AliBat may be used as part of a non-combustible exterior cladding system on buildings greater than 10M in height
• AliBat has been subjected to testing by BRANZ Structural Engineers with performance verified up to design differential pressures of 6.09 kPa. While testing was carried out on panels having Nu-Wall cladding affixed, similar performance may be expected with other cladding materials appropriately fixed to the AliBat battens in accordance with their manufacturers’ specifications
• Can be installed vertically or horizontally
• When fixed appropriately, can form a structural element
• Suitable for use with timber or steel framing and structural concrete — Alibat can be used over a variety of substrates using fasteners and specs appropriate to achieve a structural fixing
