type of curtain walling where the glass is primarily retained by a perimeter seal(3.21) and maybe witha supplementary mechanical restraint (see Figure A.8)
Note 1 to entry: Formerly known as structural sealant glazing (SSGs).3.2
type of curtain walling construction comprisingglazed or infilled sub-frames inserted in to a frameworkof usually vertical and/or horizontal profiles
component which protects the junction between the curtain walling and the roof edge from weather(see Figure A.9)
cover capface cover
profiled external cover applied, usually snap fitted, over the face of the pressure plate (3.22 ) to providean architectural finish (see Figure A.1,Figure A.3 and Figure A.4)
cradle guidegondola guide
specially profiled continuous recess or projection designed into or separately attached to the mullion(3.20) to provide a location guide for an access cradle (see Figure A.1)
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 partthereof, 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 curtainwalling.

assembly of components designed to transmit all actions on the curtain walling (3.6) back to the buildingstructure while allowing any required movement (see Figure A.1)
length of profiled material used around the periphery of a pane of glass, insulating glass unit (3.16) orinfill panel (3.14) to secure it in its frame
Note 1 to entry: Term “glazing stop” is also used in some countries.3.12
amorphous sealing material installed between face of a glass pane, insulating glass unit (3.16) or infillpanel (3.14) and the surrounding frame,glazing bead (3.11) or pressure plate (3.22)
horizontal framing member positioned at the top of the curtain walling (3.6) or at the top of an area ofglass, windows, panels or doors (see Figure A.1 and Figure A.6)
