Abstract
An improved device for use in a cavity-wall construction includes a water-permeable body yielding a first-average opening size that is large enough to permit water to pass therethrough, but small enough to substantially prevent mortar and other debris from passing therethrough. The device includes a water-permeable material likewise adapted to permit water to pass therethrough, but also forms a barrier to insects which are of an effective size that is much smaller than the first-average opening size.
