Description

Verification Method E2/VM1 provides a means of compliance with Building Code Clause E2.3.2 of cladding systems and associated window and door junctions only, for buildings of importance Levels 1 or 2 as described in Table 1.1(a) of NZS 3604. 

Builing Code Clause E2 ensures that external roof, wall claddings and external openings will prevent external moisture from causing undue dampness or damage.

It requires buildings to be constructed to provide adequate resistance to penetration by, and the accumulation of, moisture from the outside.

It contains requirements for roofs, wall claddings and external openings to:

  • prevent water entry
  • prevent water absorption and transmission
  • prevent the accumulation of water
  • allow for dissipation.  

Scope

This Verification Method is restricted to buildings that:

  • a) are in accordance with the scope of Paragraph 1.0 of E2/AS1, and within the wind zones covered by Section 5 of NZS 3604, and
  • b) have claddings that include a drained and vented cavity of nominal 20 mm minimum depth with minimum ventilation opening of 1000 mm2/m at the foot, including any claddings that require a rigid wall underlay in accordance with Paragraph 9.1.7.2 of E2/AS1, and
  • c) include window and door units that are manufactured to comply with the relevant requirements of NZS 4211, and
  • d) may include buildings based on (a), (b) and (c) above, but with specific engineering design frame elements of at least equivalent stiffness to the framing provisions defined in NZS 3604.

It may also be used for individual buildings that comply with  (a) to (d) above, and that are designed for a specific wind pressure up to a maximum ultimate limit state (ULS) of 2500 Pa.
