An off-ridge roof ventilation device for placing on an opening of a roof deck. The ventilation device comprises an elongated main hood with a curved shape. The right end of the main hood is closed by a right-side panel, and the left end of the main hood is closed by a left-side panel. The main hood comprises a perforated top face and a venting opening on a bottom face. A throat panel is placed on the bottom face of the main hood in a manner to reduce the venting opening. A perforated interior panel is placed between the top face of the main hood and the throat panel to eliminate wind driven rain and/or snow even in high wind situations. The perforations are preferably designed as mini-louvers, wherein the mini-louvers of the main hood and the mini-louvers of the throat panel comprise the same shape and count the same number.

A ventilated solar panel system mounted on a roof of a building (1), comprising a plurality of joists (12, 112) arranged substantially normal to an upper ridge (14) of the roof, and extending from the upper ridge (14) to a lower region of the roof, and a set of rectangular solar panels (2, 13), arranged on and supported by the joists (12, 112). The system further comprises a set of electrical fans (25), each fan (25) being arranged in the lower region of the roof and being aligned with one of the joists (12, 112), wherein each fan (25) is configured to create a flow of air towards the ridge (14), and wherein each joist (12, 112), in an end facing one of the fans (25), is formed with a dividing edge (32, 132) configured to divide the flow of air into two sub-flows (26a, 26b), a first sub-flow (26a), directed to a first side of the joist (12, 112), and a second sub-flow (26b) directed to a second side of the joist (12, 112), opposite to the first side.

A ridge vent for ventilating a roof of a building via a hole along a roof ridge to atmosphere, the ridge vent comprising a first ridge vent panel: a flange portion for resting on the roof, the flange portion having an opening for overlapping with the hole, the flange portion having a first flange portion positioned to one side of the opening and a second flange portion positioned to another side of the opening, such that the first flange portion and the second flange portion are at an acute angle with respect to one another; a frame portion coupled to the flange portion and having sides extending upwardly from the flange portion about the opening, the frame portion for maintaining a cap portion in a spaced apart relationship with the flange portion; the cap portion connected to the frame portion and covering over the opening; a first corrugated filter plate extending between the cap portion and the flange portion and positioned transversely between the opening and the atmosphere, the first corrugated filter plate positioned to said one side of the opening; and a second corrugated filter plate extending between the cap and the flange portion and positioned transversely between the opening and the atmosphere, the second corrugated filter plate positioned to said another side of the opening; wherein the corrugated filter plates providing for a passage of air between the atmosphere and the opening, the corrugated filter plates having a pore size sufficient for facilitating the air passage of air through the corrugated filter plates while blocking passage of atmospheric particles through the corrugated filter plates.

A framing assembly has at least one rafter vent assembly having a connecting member with a plurality of vent tubes for providing supplemental ventilation and additional structural support to a frame of a building structure. The at least one rafter vent assembly may be an interior rafter vent assembly or an exterior rafter vent assembly. The interior rafter vent assembly has at least one brace member and a connecting member, with the connecting member having a connecting plate, two end plates, and the plurality of vent tubes. The exterior rafter vent assembly has the connecting member that has a connecting plate and the plurality of vent tubes. The framing assembly also preferably has a plurality of modified structural insulated panels (SIPs) and modified rafter splines.

A ridge vent system is provided including a ridge vent having opposing exterior sidewalls that each define multiple fastener recesses that extend inward from the exterior sidewalls and downward from a top plate. The ridge vent can include ventilation elements within the exterior sidewalls and/or fastener recesses. The ridge vent can include an air permeable filter membrane that can be secured to bottom walls of the fastener recesses to impair environmental elements from entering a structure therethrough, yet still provide air flow out the vent. The ridge vent can be in sheet or roll form, depending on the application. The ridge vent can provide enhanced attic ventilation and/or airflow through the ridge vent, while still providing fastener recesses that facilitate rapid and efficient application of fasteners therethrough.

Greenhouse comprised of a ridge beam extending some distance above its roof defining two elongated side zones at either side of the ridge beam. The ridge beam is comprised of one or more elongated hollow spaces and with one or more closable openings in both side zones. The openings fluidly connect the exterior of the greenhouse with its interior and may be closed at one side and opened at its other side depending on the direction of the wind.

A vent is disclosed that is particularly suited to use in ventilating attic spaces beneath a hip roof. The vent is configured to be installed along a hip of the roof overlying and covering a ventilation slot formed through the roof deck along the hip. The vent includes an elongated laterally flexible top panel from which baffle arrays depend. The baffle arrays are formed of a plurality of depending arcuately curved vanes that arc away from the vent. The vanes are aerodynamically shaped to redirect wind-blown rain and snow away from the vent and are configured to block the migration of rain and snow through the vent. A pair of spongy conformable filler strips is attached beneath the edge portions of the vent. The filler strips conform to the shapes of underlying shingles when the vent is installed to fill any gaps that otherwise might be formed between the vent and the shingles. A weather filter drapes over some of the baffle arrays to allow attic air to pass but prevent ingress of blown snowflakes and raindrops.

Roof beams or ridges having configurable vent or flue openings therein are disclosed. Such members may be used in tents or other temporary structures to allow for versatility in positioning stoves, heaters, or other apparatuses requiring exterior venting therein.

Ridge vents and deck covers are disclosed that have a fibrous mesh mat and a moisture barrier. The mesh mat may be contoured to define a variety of structures and may have regions of relatively higher fiber density and regions of relatively lower fiber density. Solar cells may be exposed on the ridge vents to collect solar energy when the vents are exposed to sunlight.
