A gutter guard for filtering water that enters a rain gutter on a building includes: a barrier member configured to be positioned above a lowest portion of the rain gutter and having a plurality of openings that are penetrable by water, the barrier member having first members that extend along a first direction; second members that extend along a second direction that is non-parallel to the first direction; and a protrusion extending from the barrier member. The protrusion has a first extension that comprises a first end, and a second extension that comprises a second end.

A spacer system for stacked building structures that is in mating engagement with a seal plate provided on an edge of an enclosure component.

A gutter debris preclusion device for use with a gutter having a support structure being substantially rigid; a screen having a plurality of apertures and being disposed on the support structure; and, a fastener member disposed on the support structure and having a barrier member and a protective film removably attached to the barrier member.

A kit for flashing a mount of a photovoltaic assembly on a surface includes a flashing assembly. The flashing assembly includes flashing that extends across an interface of the mount and the surface when the mount is attached to the surface. The flashing includes a bottom surface and a top surface. The flashing assembly also includes tape attached to the bottom surface of the flashing. The tape includes a first attachment area and a second attachment area. The flashing assembly has a first configuration in which the first attachment area is attached to the flashing and the second attachment area is unattached, and a second configuration in which the first attachment area is attached to the flashing and the second attachment area is attached to the surface. The tape is movable with the flashing as an assembly when the flashing assembly is in the first configuration. The first attachment area and the second attachment area positioned on opposite sides of the tape such that the tape extends between the surface and the bottom surface of the flashing when the tape is in the second configuration. The kit also includes a container defining an interior space to receive the flashing assembly.

The off-ridge roof vent with an internal water diverter includes a throat, a hood and a water diverter. The throat has a front throat wall, a rear throat wall and a pair of longitudinally opposed throat sidewalls. The throat has open upper and lower ends. The hood has an upper hood wall that is convex upward, a pair of longitudinally opposed hood sidewalls and a lower hood wall. A lower end of the hood has a rear portion, a central portion and a front portion, the rear portion being open, aligned with, and in open communication with the open upper end of the throat. The lower hood wall defines the central portion and projects forward from the front throat wall. The front portion is open, having a perforated grating mounted therein. A water diverter extends from the front edge of the lower hood wall and slopes above the grating.

A water diverter for diverting water on a building roof or gutter is provided. The diverter includes a main body having a first portion having a top side and a bottom side, a diverting portion extending from the top side of the first portion at a first angle, the first angle being an angle greater than zero degrees, and an attachment portion extending from the first portion and being configured to attach to the building roof or gutter; a first opening in one of the first portion and the diverting portion, the first opening being configured to allow the water to pass through the one of the first portion and the diverting portion; and a filter element positioned above the first portion of the main body and through which the water can pass.

A cover for water flow inlet for rainwater drainage of roof and buildings is disclosed. The inlet cover comprises an outer formation forming a plurality of ridged fins to avoid the vortex formation of rainwater entrainment and to protect the cover from debris materials and a central plate member. The central plate member has a profiled lower surface. The plate member is of an inverted shape with a plurality of ridged formation or channels on the lower surface to further eliminate formation of air inducing and vortices, therefore promoting high volume laminar flow of water in the inlet pipe of the drainage system.

A gutter guard for filtering water that enters a rain gutter on a building, the gutter guard having a barrier member configured to be positioned above a lowest portion of the rain gutter and having a plurality of openings that are penetrable by water. The barrier member having first members that extend along a first direction; second members that extend along a second direction that is non-parallel to the first direction; a third member made of an ion-dispersing material; and a protrusion extending from the barrier member.

The invention relates to a device for draining a liquid, in particular rainwater, from a first film layer (4) which forms at least one part of a building cladding element. A first valve element (26) can be arranged in the region of a first opening (22) provided in the first film layer (4) such that the valve element can be pivoted between a first position, which closes the first opening (22), and a second position, which at least partly releases the first opening (22). Additionally, first opening and closing means (30, 32, 34) which can be attached to the first film layer (4) are provided, said means being designed to keep the first valve element (26) in the first position as long as the pressure (40a) of a liquid (40) which has arrived on the upper face of the first film layer (4) is less than a specified first threshold or maximally equal to said threshold, said pressure acting on the first valve element (26), allow the first valve element (26) to pivot from the first position to the second position if the liquid (40) pressure (40a) acting on the first valve element (26) exceeds the first threshold, and pivot the first valve element (26) from the second position to the first position after the liquid (40) pressure (40a) acting on the first valve element (26) is substantially no longer present.
