Curtain walling and cladding


Curtain walling and cladding systems shall have suitable interfaces and resist the penetration of water and wind.

The design should indicate the contractor responsible for constructing interfaces.

Interfaces, including those between curtain walling and cladding systems, and those between curtain walling and cladding systems and other elements of the building (e.g. walls, roof, doors and windows), should be carefully designed and detailed to be weather resistant, and prevent moisture reaching parts of the wall that it could adversely affect.

The design should take account of:

  • differing profile characteristics
  • movement
  • continuity of insulation, vapour barriers and breather membranes
  • tolerances and deviation
  • the erection sequence
  • planned maintenance.
