E04B2/18 - CPC Classification

Classification description:

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 in, but not between, the elements, i.e. each cavity being enclosed by at least four sides forming part of one single element using elements having specially-designed means for stabilising the position by interlocking of projections or inserts with indentations, e.g. of tongues, grooves, dovetails
