Description

The Nu-Wall Aluminium Vertical Weatherboard Cavity System is a cavity-based, inter-locking, powder coated aluminium weatherboard system.

It is designed to be used as an external wall cladding system for residential and light commercial type buildings where domestic construction techniques are used.

The system includes vertically fixed Nu-Wall weatherboards, cavity battens, internal and external corner mouldings, base channel, board jointers, board locators, soffit caps, joinery flashings and accessories.

The system incorporates a primary and secondary means of weather resistance (first and second line of defence) against water penetration by separating the cladding from the external wall framing with a nominal 20 mm cavity.

Scope

The Nu-Wall Aluminium Vertical Weatherboard Cavity System has been appraised as an external wall cladding for buildings within the following scope:

  • the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1; and,
  • with a risk score of 0-20, calculated in accordance with NZBC Acceptable Solution E2/AS1, Table 2; and,
  • situated in NZS 3604 Wind Zones up to, and including Extra High.

The Nu-Wall Aluminium Vertical Weatherboard Cavity System has also been appraised for weathertightness and structural wind loading when used as an external wall cladding system for buildings within the following scope:

  • the scope limitations of NZBC Acceptable Solution E2/AS1, Paragraph 1.1 with regards to building height and floor plan area; and,
  • constructed with timber and steel framing subject to specific engineering design; and,
  • situated in specific design wind pressures up to a maximum design differential ultimate limit state (ULS) of 2.5 kPa.

The Nu-Wall Aluminium Vertical Weatherboard Cavity System must only be installed vertically on vertical, flat surfaces.

The Nu-Wall Aluminium Vertical Weatherboard Cavity System is appraised for use with aluminium window and door joinery that is installed with vertical jambs and horizontal heads and sills. (The Appraisal of the Nu-Wall Aluminium Vertical Weatherboard Cavity System relies on the joinery meeting the requirements of NZS 4211 for the relevant Wind Zone or design wind pressure.)
