<p>A cavity wall spacer, a building structure and method are disclosed. The cavity wall spacer determines a separation of building elements of two leaves of a wall during construction. The cavity wall spacer comprises: a support body; and a plurality of spaced projections upstanding from the support body and operabl e to extend across a cavity between the two leaves, each projection having a recessed channel operable to inhibit transfer of moisture from one end of each projection to another. The recessed channel or groove helps to prevent the passage of moisture along the length of the projection which provides an efficient way of preventing moisture travelling between the two leaves of the wall. Also, a recessed channel reduces the amount of moisture which drips into the cavity since the moistur e is more likely to track back along the surface of the projection. Additionally, providing a recessed channel ensures no external obstruction on the projections which helps to achieve a significantly improved stacking density. Furthermor e, the projections are less prone to any damage since there are no external protrusions.</p> |
