The National Building Specification (NBS) is one of the most widely used frameworks for specifying construction in the UK.  It provides architects with specification clauses that match the architectural packages of work.  In particular:
  • NBS Section H11 Curtain walling invokes the CWCT Standard for curtain walling
  • NBS Section H92 Rainscreen cladding invokes the CWCT Standard for walls with ventilated rainscreens


Further details of the National Building Specification are available here.
