Acceptable Solution E2/AS1 provides a means of compliance with Building Code Clause E2 External Moisture.
Building Code Clause E2 requires external roof, wall claddings and external openings to 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; and allow for dissipation.
This Acceptable Solution coves the weathertightness of the building envelope.
The scope of this Acceptable Solution is limited to the materials, products and processes contained herein, for buildings within the scope of NZS 3604, and:
a) Up to 3 storeys with a height measured from lowest ground level adjacent to the building to the highest point of the roof (except for chimneys, aerials and the like) of 10 m or less, and
b) With floor plan area limited only by seismic and structural control joints, and
c) External walls that are vertical, and roofs that are 60 or less above the horizontal. Where buildings are based on NZS 3604, but require specific engineering design input, the framing shall be of at least equivalent stiffness to the framing provisions of NZS 3604.
This Amendment includes Alterations on:
