E04B 2/28 Walls having cavities between, but not in, the elements; Walls of elements each consisting of two or more parts kept in distance by means of spacers, all parts being solid
Introduced: September 1968
Full Title
Full titles differ between systems:
Walls, e.g. partitions, for buildings; Wall construction with regard to insulation; Connections specially adapted to walls > built-up from layers of building elements > Walls having cavities between, but not in, the elements; Walls of elements each consisting of two or more parts kept in distance by means of spacers, all parts being solid
Walls, e.g. partitions, for buildings; Wall construction with regard to insulation; Connections specially adapted to walls (connections for building structures in general E04B1/38; insulation for buildings in general E04B1/62; building elements of relatively thin form for parts of buildings E04C2/00) > built-up from layers of building elements > Walls having cavities between, but not in, the elements; Walls of elements each consisting of two or more parts kept in distance by means of spacers, all parts being solid
IPC and CPC are identically structured here. All 4 subcodes exist in both systems.
