What Is a Cavity Wall? A cavity wall consists of a hollow space between them. The cavity walls normally consist of two skins, which should be brick, cinder blocks, or reinforcement concrete blocks, etc. The absorbent materials are used in cavity wall construction to that draw out the rainwater and consist of humidity in the wall.

Simply stated, a cavity wall is two wythes of masonry, separated by a cavity of varying dimension. The mason-ry wythes may consist of solid brick, structural clay tile, or concrete masonry units and are bonded together with masonry ties. The cavity (ranging from 2 inches to 4 1/2 inches in width) may or may not contain insulation. See Figure 1.
