Nu-Wall Weatherboard



Nu-Wall Aluminium weatherboard system on AliBat non-combustible cavity battens. The Nu-Wall weatherboard system is a New Zealand made, BRANZ appraised, extruded aluminium cladding system consisting of 22 board profiles and a selection of standard flashings.

A wide range of finish options are available and Nu-Wall offers a 100 year substrate and 20-25 year coating warranty, making it a very suitable system for MDH. The aluminium used to produce Nu-Wall is at least 90% recycled aluminium collected from New Zealand.


Nu-Wall offers both a non-combustible structural batten system as well as a traditional gauged thickness cavity batten system. Because the system is locally produced and not subject to the current international logistics backlog, the MDH project will not be held up awaiting cladding.

The completed wall system has BRANZ tested performance, watertightness (to 4.5KPa), high wind pressure (to 6.09KPa), non- combustible, seismic (72mm in P21 test).

Nuwall Types


  • The Nu-Wall system provides a selection of board profiles, that although visually different, are technically identical – all 10.8mm thick, all use same underlap/ overlap and all use the same flashing system.
  • This uniformity allows builders to develop a system familiarity regardless of profile.
  • Designers are also free to inter-mix profiles and colours to achieve unique appearances.
  • Boards can be supplied up to 8.3m lengths where long-run is desired.
  • Durable cladding system with low maintenance requirements (typically an annual wash) ideal for MDH projects.
