AliBat was developed by Nu-Wall in response to the Amendment in early 2017 to NZBC Clauses C/AS2-7, which applied restrictions to the use of combustible exterior cladding systems. AliBat is extruded from 6061-T6 aluminium alloy; being categorised as non-combustible it can form part of a non-combustible cladding system as defined by NZBC Clause C3. As such, AliBat may be used as part of a non-combustible exterior cladding system on buildings greater than 10m in height.
AliBat has additionally been designed to perform as a structural element and has been subjected to testing, incorporated into panels clad with Nu-Wall, by BRANZ Structural Engineers, with wind pressure performance verified up to design differential pressures of 6.09 kPa.
While primarily developed for incorporation into installations of Nu-Wall Aluminium Cladding, AliBat is compatible for use with a variety of cladding products; similar performance may be expected with other cladding materials when appropriately fixed to the AliBat battens in accordance with their manufacturers’ specifications.
AliBat is supplied pre-drilled in 5.8m lengths and may be incorporated as a structural element onto a range of substrate materials using appropriately-specified fasteners. AliBat can be installed vertically or horizontally to suit the fixing requirements of the cladding material being used. The product is stocked in mill-finish or can be supplied with an oven-baked powdercoat finish applied.
