Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

3.6
curtain walling
part of the building envelope made of a framework usually consisting of horizontal and vertical profiles,
connected together and anchored to the supporting structure of the building, and containing fixed and/
or openable infills, which provides all the required functions of an internal or external wall or part
thereof, but does not contribute to the load bearing or the stability of the structure of the building
Note 1 to entry: Curtain walling is designed as a self-supporting construction which transmits dead-loads,
imposed loads, environmental loads (wind, snow, etc.) and seismic loads to the main building structure.
Note 2 to entry: In some English speaking countries, the term “curtain wall” is also used to describe curtain
walling.
Note 3 to entry: The term “curtain wall” in English may be used for other types of external wall.
Note 4 to entry: Fixed and/or openable infills can be described as fixed and/or openable parts in some countries.
3.7
double skin curtain walling
type of curtain walling (3.6) comprising inner and outer skins and an air cavity, designed and supported
as an integrated system fulfilling the functions of the curtain walling (3.6) (see Figure A.7)
