Abstract: Weep hole insert (10, 10) comprising a tubular body (12) defining an air flow conduit (14) extending therethrough, along axis (L), from a first open end (12a) to a second open end (12b) of the body. Grate (16) comprises a perforated body (16a) configured to permit air flow but to inhibit passage of embers and sparks. In an operative configuration, perforated body (16a) extends across the conduit (14). Elastically compressible member (16c) is engageable between perforated body (16a) and an interior surface of body (12) to releasably secure the perforated body in the operative configuration. When engaged between body (16a) and the interior surface of body (12), member (16c) is elastically compressed from an expanded configuration to a compressed configuration by a distance of at least a wall thickness (T) of body (12) at its point of engagement by member (16c).

Abstract: A pest barrier (10, 10?, 10?, 10??, 10??), comprising a body (12, 112) for installation in or over an opening in a building to inhibit passage of pests through the building opening (200, 302). Body (12, 112) is formed from one or more components and comprises one or more first opening (18, 28, 29, 116) extending therethrough to facilitate ventilation through the building opening when the body is installed therein or thereover. A pest repellent is carried by at least part of body (12, 112) and has efficacy within a first zone extending a predetermined first distance inwardly from a perimeter of the one or more first opening (18, 28, 29, 116) to deter one or more target pest species from passing through the one or more first opening and/or within a second zone extending a predetermined second distance outwardly from the body (12, 112) toward the periphery of the building opening (200, 302) to deter said one or more target pest species from passing through each of one or more second opening in the second zone.

Abstract: Disclosed herein is a weep hole insert (10, 10?) for providing a barrier in a weep hole (11). A handle (24, 24?) for facilitating insertion of the insert (10, 10?) in the weep hole (11) is also disclosed.

Abstract: An insert (1) for a weep hole opening in a masonry wall is disclosed. The insert (1) includes a hollow body (2) defining an air flow conduit (3) and including a first open end (4) and a second open end (5). A stainless steel mesh screen (6) extends across the conduit (3) near the first open end (4) and is adapted to prevent fire brands and sparks from passing through the body (2). A locating member, in the form of a grate (7), is hingedly connected to the body (2) adjacent the first open end (4). The screen (6) is located in a recess (8) in the rear of the grate (7) and friction between the screen (6) and the grate (7) retains the screen (6) in the recess (8). The grate (7) is formed from a material that substantially retains its spatial integrity when exposed to the heat flux profile generated by a typical forest fire, such that the grate (7) continues thereafter to locate the screen (6). The grate (7) also has a plurality of ventilation apertures (9) to allow air to pass through the air flow conduit (3).
