Type definition

This enumeration defines the different types of walls that can further specify an IfcWall or IfcWallType.

HISTORY  New enumeration in IFC2x2.
IFC2x2 CHANGE  The enumerator POLYGON has been changed to POLYGONAL.
IFC2x3 CHANGE  The enumerators ELEMENTEDWALL and PLUMBINGWALL have been added.
IFC4 CHANGE  New enumerators MOVABLE, PARAPET, PARTITIONING, and SOLIDWALL have been added.
IFC4 DEPRECATION  The enumerators STANDARD, POLYGONAL and ELEMENTEDWALL are deprecated and shall no longer be used.
NOTE  The potentially misleading term SHEAR shall not impose a particular resistance against shear forces, but a particular shape.
Enumeration definition
MOVABLEA movable wall that is either movable, such as folding wall or a sliding wall, or can be easily removed as a removable partitioning or mounting wall. Movable walls do normally not define space boundaries and often belong to the furnishing system.
PARAPETA wall-like barrier to protect human occupants from falling, or to prevent the spread of fires. Often designed at the edge of balconies, terraces or roofs.
PARTITIONINGA wall designed to partition spaces that often has a light-weight, sandwich-like construction (e.g. using gypsum board). Partitioning walls are normally non load bearing.
PLUMBINGWALLA pier, or enclosure, or encasement, normally used to enclose plumbing in sanitary rooms. Such walls often do not extent to the ceiling.
SHEARA wall designed to withstand shear loads. Such shear walls are often designed having a non-rectangular cross section along the wall path. Also called retaining walls or supporting walls they are used to protect against soil layers behind.
SOLIDWALLA massive wall construction for the wall core being the single layer or having multiple layers attached. Such walls are often masonry or concrete walls (both cast in-situ or precast) that are load bearing and fire protecting.
STANDARDA standard wall, extruded vertically with a constant thickness along the wall path.
The value is deprecated, it is expressed by choosing the subtype IfcWallStandardCase.
POLYGONALA polygonal wall, extruded vertically, where the wall thickness varies along the wall path.
ELEMENTEDWALLA stud wall framed with studs and faced with sheetings, sidings, wallboard, or plasterwork.
The value is deprecated, it is expressed by choosing the subtype IfcWallElementedCase.
USERDEFINEDUser-defined wall element.
NOTDEFINEDUndefined wall element.
