Abstract: A roof exhaust for exhausting gas from a building is provided. The roof exhaust includes: an enclosure including a base and a hollow body extending from said base, the enclosure having side sections and a front section extending between the side sections; a conduit extending within the hollow body along a central axis, the conduit having an inlet connectable to a source of gas and an outlet for exhausting the gas from the conduit; a hood extending in the front section over the outlet, the hood comprising an aperture and being configured to direct gas exiting the outlet through the aperture in a downward direction towards the base; and a damper hingedly mounted relative to the outlet and including a counterweight configured to bias the damper towards a closed position.

Abstract: An exhaust vent has a plate that mounts on a building external wall. Attached to the plate is a main body with an aperture extending therethrough, and a first seal surrounding the aperture. A flap is pivotally attached to the body, alternately opening and closing the aperture. The flap has an inner surface having a flange projecting therefrom. The flange fits within a groove provided within the main body, the groove having a second seal recessed therein. The groove and abuts the body second seal when the flap is in the closed position.

Abstract: An exhaust which comprises a mounting plate mountable onto the external wall of the building and having an opening therein. The exhaust vent also comprises a main body attachable to the mounting plate and having a rear face, a front face, and an aperture extending from the rear face to the front face in fluid communication with the opening of the mounting plate and the conduit. The exhaust vent also comprises a flap pivotally attached to the main body and movable between a closed position, where the aperture is blocked by the flap, and an opened position where the flap extends away from the aperture. Finally the exhaust vent comprises a first seal which surrounds the aperture when the flap is in the closed position, the seal being located on either one of the flap or the main body. This invention aims at improving air-tightness of the exhaust vent when in the flap is in the closed position.

Abstract: A roof ventilator including: a first module defining a first module passageway having a first passageway longitudinal axis. The first module including a first module louver support extending substantially parallel to the first passageway longitudinal axis and a first module louver for creating a draft within the first module passageway upon wind blowing onto the first module louver. The first module louver extending from the first module louver support, located peripherally relatively to the first module passageway. A second module attached to the first module, defining a second module passageway, in fluid communication with the first module passageway and defining a second passageway longitudinal axis. The second module including a second module louver support, extending substantially parallel to the second passageway longitudinal axis. A second module louver creates a draft within the second module passageway upon wind blowing onto the second module louver.

Abstract: A roof ventilator mount for mounting a roof ventilator onto a gable-type roof (21), the roof ventilator including a roof ventilator base (10) defining a cupola mounting portion (25) for mounting a cupola (12) thereto, the roof ventilator mount comprising: a first mounting component (26), the first mounting component (26) including a first mounting plate (48) mountable to the roof (21); a second mounting component (26), the second mounting component (26) including a second mounting plate (48) mountable to the roof (21); the first and second mounting components (26) being mountable to the roof ventilator base (10) with proximal edges (47) thereof located substantially adjacent to each other and distal edges (49) thereof located spaced apart from each other; the first and second mounting plates (48) being each provided with a breakable segment (66) extending from the proximal edge (47), the breakable segment (66) being breakable from the remainder of the mounting plate (48) along a predetermined break line locat

Abstract: A new exhaust vent has a mounting plate that mounts onto an external wall of a building Attached to the mounting plate is a main body that has an aperture that extends between a rear face and a front face that is in fluid communication with an opening of the mounting plate. A flap is pivotally attached to the main body and moves between a closed position, where the aperture is blocked by the flap, and an opened position, where the flap extends away from the aperture. A seal surrounds the aperture when the flap is in the closed position.
