  • ii. NASH building Envelop Solution (2019) Table 23 for steel framed buildings, or
  • iii. a current Codemark certificate or BRANZ appraisal demonstrating suitability for the use conditions, and
• b. Directly fixed or fixed over a ventilated cavity in accordance with Table 3, E2/AS1 or E2/AS4. For applications not referenced in the applicable acceptable solution, the cladding will be installed over a ventilated cavity, and
• c. used on buildings with a risk score not greater than 20, when evaluated against:
  • i. NZBC Acceptable Solution E2/AS1, Third Edition including amendment 10 (5/11/2020) risk matrix for timber framed building or
  • ii. NASH building Envelope Solution (2019) risk matrix as referenced by E2/AS4 for steel framed buildings, and
• d. used with aluminium window and door joinery that meets the requirements of NZS 4211:2008 including amendment 1 or has a current Product Certificate or with traditional timber joinery as set out in BRANZ bulletin BU481, and
• e. where Pineclad is finished with a paint coating, the LRV of the top coating paint must not be less than 45% (excludes Pineclad TMT).
