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).

A through-wall flashing support system for supporting a through-wall flashing membrane installed in a cavity wall. The system includes multiple support parts, multiple spline parts and a through-wall flashing membrane. Each support part has a flange, configured to abut and be attached to an inner wall of the cavity wall, and a base, extending with a downward slope from the lower portion of the flange such that the outer portion of the base penetrates an outer wall of cavity wall. Spline parts are configured to connect adjacent support parts. The through-wall flashing membrane extends across the cavity and covers the bases of the support parts and the spline parts. Weep holes are installed to enable water to flow through the outer wall along through-wall flashing membrane. Methods for installing this system in a new cavity wall and retrofitting an existing cavity wall are also provided.

Method and apparatus for a rectangular shaped body which forms a receiver for moisture that collects in or about the drainage plane behind an Exterior Insulation and Finish System which receiver collects the water and allows the water to drain away from the wall system to the outside of the finished wall through at least one drainage tube. The receiver body is expected to be installed behind the Expanded Polystyrene on front of the exterior surface of the interior sheathing.

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.

A fenestration flashing system includes a body member having a planar header leg extending horizontally from a rearward end to a forward end, a vertical leg extending upward from the forward end of the header leg, and a positively-sloped drainage leg extending upwardly and rearwardly from a top end of the vertical leg. A termination member has a vertical termination leg for attachment to the back-up wall and a positively-sloped drainage leg to overlap and attach to the positively-sloped drainage leg of the body member. The termination member and the body member define a drainage path down and out of the wall cavity. A method of flashing a fenestration of a cavity wall or non-cavity wall is also disclosed.

The present disclosure is directed to casing accessories for use with multi-component wall systems. Some of the casing accessories of the present disclosure can include a mounting bracket to attach the accessory to a wall structure and a channel formed in part by a spacer that can be adjusted to adjust the channel width in order to encase components of multi-component wall systems that can vary in width from one installation to another. In another aspect, some of the casing accessories can include one or more drainage canals that direct water from one part of the casing accessories to another. In another aspect, some of the casing accessories can impede fire propagation through multi-component wall systems.
