IfcCurtainWall
What is IfcCurtainWall?
IfcCurtainWall represents a non-load-bearing exterior wall system that is hung from the building structure, typically consisting of a metal frame with glass, metal, or stone panel infill. Curtain walls carry only their own weight and wind loads, transferring these to the primary structure at each floor.

Real-World Usage
Curtain wall systems are typically the most expensive facade element per square meter. Construction teams coordinate installation sequences with structural frame progress and track panel deliveries, as each panel is often custom-sized.

IfcWall
IfcWall represents a vertical construction element that bounds or subdivides spaces. Walls are one of the most fundamental building elements in any IFC model, defining the physical envelope and internal partitioning of a building. IfcWall can represent both load-bearing structural walls and non-load-bearing partitions.
Building ElementIfcWindow
IfcWindow represents a construction element placed in a wall opening to allow light and ventilation. Windows carry properties about their glazing type, thermal performance, operation type (fixed, casement, sliding), and dimensions.
Building ElementIfcPlate
IfcPlate represents a planar, flat structural element with a constant thickness. Plates are commonly used in steel construction for gusset plates, base plates, connection plates, and cladding panels. In curtain wall systems, IfcPlate often represents individual glass or metal panels.
Building ElementIfcMember
IfcMember represents a structural element that carries loads primarily in tension, compression, or bending along a single axis. Members include bracing, struts, purlins, mullions, and other linear structural components that are not classified as beams or columns.
