1 Scope
This document specifies the structural performance requirements of curtain walling
under wind load, both its fixed and openable parts, under positive and negative static pressure.
This document applies to any curtain walling product as defined in EN 13830.
NOTE Due to the many diverse elevational layouts and dimensional variations which are accommodated by curtain walling installations, it is not practical to structurally classify the large variety of curtain walling systems and purpose designed constructions.
