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

Constant | Description
--- | ---
MOVABLE | A 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.
PARAPET | A 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.
PARTITIONING | A 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.
PLUMBINGWALL | A pier, or enclosure, or encasement, normally used to enclose plumbing in sanitary rooms. Such walls often do not extent to the ceiling.
SHEAR | A 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.
SOLIDWALL | A 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.

STANDARD

A standard wall, extruded vertically with a constant thickness along the wall path.

> The value is deprecated, it is expressed by choosing the subtype IfcWallStandardCase.

POLYGONAL | A polygonal wall, extruded vertically, where the wall thickness varies along the wall path.

ELEMENTEDWALL

A 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.

USERDEFINED | User-defined wall element.
NOTDEFINED | Undefined wall element.
