IfcWindow
What is IfcWindow?
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.

Real-World Usage
Windows are critical for energy performance calculations. Construction teams track window specifications for procurement, verify thermal transmittance values for code compliance, and manage installation schedules by floor.

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 ElementIfcDoor
IfcDoor represents a construction element that is used to close an opening in a wall or partition. Doors provide access between spaces and carry properties about their operation type (single swing, double swing, sliding, revolving), fire rating, and accessibility compliance.
Opening ElementIfcOpeningElement
IfcOpeningElement represents a void or hole cut through a building element such as a wall, slab, or roof. Openings are used to accommodate doors, windows, ducts, pipes, and other penetrations. The opening itself is a subtractive element — it defines the shape to be removed from its host element.
Building ElementIfcCurtainWall
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.
