BRANZ Junctions Seminar

E2/AS1 provides a limited number of junction details based on junctions between a single material such as weatherboard (internal and external corners) and elements such as aluminium windows and doors.

The aim of this seminar is to cover the key influences on junction details such as:

  • Building Code clauses B2 and E2 - minimum B2 requirements, what E2/AS1 covers
  • Application of the 4Ds to junctions - cavity, cladding flashings
  • Impact of location - sheltered/exposed, internal corner, external corner, above/below
  • Risks - weathertightness, durability, trapped moisture, getting it wrong, drainage/drying, corrosion, wind, complexity/buildability, compatibility
  • Dealing with movement - thermal, moisture, building settlement, seismic
  • Protection to junctions - flashings (shapes, back upstand/cover, laps), cover boards, sealant
  • Dealing with different thicknesses/profiles - thin versus thick or vice versa, flat versus corrugate
  • Maintenance issues, future access
  • Fixing locations
  • Aesthetic - the transition needs to look good
  • Pressure moderation across junctions.

The seminar will then take the attendee through a wide range of actual junction details backed by 3D drawings of those details such as:

  • Vertical wall cladding material junctions within the wall area and at corners such as profiled metal/weatherboard, weatherboard/brick veneer
  • Horizontal wall cladding material junctions such as weatherboard over brick veneer
  • Wall cladding over roofs (horizontal/raked aprons)
  • Wall cladding below roof (flush eaves, wide eaves)
  • Parapets, valleys, ridges, gables and hips
  • Rainwater heads and internal gutters.
