Description
- This application claims the benefit of U.S. Provisional Application Ser. No. 60/717,382 filed Sep. 15, 2005; U.S. Provisional Application Ser. No. 60/717,383 filed Sep. 15, 2005; and U.S. Provisional Application Ser. No. 60/597,129 filed Nov. 11, 2005, the entire specifications of all of which are expressly incorporated herein by reference.
- The present invention generally relates to a duct assembly for disposition in an attic of a building. The present invention further relates to a method of using the duct assembly in the attic.
- Traditionally, vents include convection driven vents and power driven vents. The vents are disposed in an attic of a building, such as a residential or commercial building. The attic of the building is defined by a ceiling of the building and by a roof or a roof and a gable. The vents are mounted to the building and extend through the roof and/or the gable between the attic and an exterior of the building.
- Convection driven vents allow air to flow between the exterior of the building and the attic by convection. Power driven vents include fans for forcing air to move between the exterior of the building and the attic. The powered vent may be connected to an atmospheric control system that, for example, senses atmospheric conditions inside the attic and supplies or does not supply power to the fan based on the atmospheric conditions.
- The vents allow movement, or force movement of air between the exterior of the building and the attic to reduce the temperature of the air in the attic and to reduce the humidity of the air in the attic. The low temperature of the air in the attic is important in winter months to prevent ice dams. In other words, if the temperature of the attic is too high relative to the snow on the roof, the snow will melt and the water from the melted snow will flow down the roof and refreeze as ice. The refreezing ice causes damage to the roof and eventually leads to water intrusion and mold growth. The low temperature of the air in the attic is important in the summer months to aid in the efficiency of the cooling of the building. Low humidity of the air in the attic prevents mold growth in the attic.
- Buildings may also include a soffit, or an overhang where the roof and the ceiling of the building meet. The overhang defines an eave and a vent is generally mounted in the soffit to allow the flow of air through the eave.
- Some buildings include complexly shaped attics that result in stagnant areas of the attic. Air does not naturally flow through the stagnant areas of the attic. In other words, the ceiling, equipment disposed on the ceiling, and complexly shaped roofs create the stagnant areas where the flow of air is not natural. In addition, not all buildings include a soffit thereby creating a stagnant area of the attic along the eave between the roof and the ceiling of the building. Vents may be mounted near the stagnant areas to allow or to force air into the stagnant area of the attic. However, depending upon the shape of the attic, it is not always practical or possible to mount a vent near the stagnant area.
- It would be desirable to manufacture an assembly that directs the flow of air from the exterior of the building and through the vents into the stagnant areas of the attic to allow air flow in the stagnant areas of the attic thereby reducing the temperature and humidity of the air in the stagnant areas of the attic.
- The present invention includes a duct assembly for disposition in an attic of a building. The duct assembly includes a first vent and a duct coupled to the first vent. The first vent defines an opening for fluidly communicating with air in an exterior of the building. The duct includes an elongated side defining a passage. The duct extends between a first end and a second end with the first end coupled to the first vent and with the passage in fluid communication with the opening of the first vent. The duct includes an end plate sized larger than the passage and sealed to the second end covering the passage at the second end. The elongated side includes an unperforated portion being unperforated and a perforated portion defining a hole for providing fluid communication from the opening of the first vent to the hole.
- The present invention further includes a method of using the duct assembly to aerate the attic of the building. The method includes the step of mounting the first vent to an orifice defined by an enclosure of the attic to fluidly communicate the opening of the vent with the air of the exterior of the building. The method further includes the step of coupling the first end of the elongated side of the duct to the first vent. The method further includes the step of locating the perforated portion of the elongated side of the duct in a stagnant area of the attic to create airflow from the exterior of the building through the opening of the first vent through the passage of the duct through the hole of the perforated portion and into the stagnant area of the attic.
- Accordingly, the duct assembly allows airflow from the exterior of the building to the stagnant areas of the attic. The method of using the duct assembly results in airflow from the exterior of the building to the stagnant area of the building. The airflow in the stagnant areas of the attic manages the temperature and humidity of the attic to prevent ice dams on a roof above the attic and to prevent mold growth in the stagnant area of the attic.
- In accordance with one embodiment of the present invention, a duct assembly is provided for disposition in an attic of a building, the duct assembly comprising: (1) a first vent defining an opening for fluidly communicating with air in an exterior of the building; and (2) a duct including an elongated side defining an elongated passage extending along a longitudinal axis (A), the duct extending between a first end and a second end with the first end coupled to the first vent and with the passage in fluid communication with the opening of the first vent; the duct including an end plate sized larger than the passage and sealed to the second end covering the passage at the second end; the elongated side including an unperforated portion being unperforated and a perforated portion defining a hole for providing fluid communication from the opening of the first vent to the hole.
- In accordance with a second embodiment of the present invention, a method is provided for using a duct assembly to aerate an attic of a building with the duct assembly including a first vent and a duct defining a passage with the duct including a first end, a second end, an elongated side extending between a first end and the second end and an end plate sized larger than the passage sealed to the second end and with the elongated side including an unperforated portion being unperforated and a perforated portion defining a hole, the method comprising the steps of: (1) mounting the first vent to an orifice defined by an enclosure of the attic to fluidly communicate an opening of the first vent with the air of the exterior of the building; (2) coupling the first end of the elongated side of the duct to the first vent; and (3) locating the perforated portion of the elongated side of the duct in a stagnant area of the attic to create airflow from the exterior of the building through the opening of the first vent through the passage of the duct through the hole of the perforated portion and into the stagnant area of the attic.

If theopen vents 36 are convection driven vents the hot air flows through theopen vents 36 by convection. If theopen vents 36 are power driven vents, the hot air is forced through the vent with, for example, a fan. When theduct assembly 20 is connected to a convection driven vent, as the hot air flows to theexterior 25 of thebuilding 24, fresh air is drawn by convection through thefirst vent 34 and through theunperforated portion 42 of theduct 40 to the perforatedportion 44 of theduct 40. The fresh air is dispersed to thestagnant area 23 of the attic 22 through the holes 51 defined in the perforatedportion 44 of theduct 40. Likewise, when theduct assembly 20 is connected to a power driven vent, as hot air flows to theexterior 25 of thebuilding 24 or when certain atmospheric conditions exist inside the attic, the power driven vent forces fresh air through theduct assembly 20. Also, when power driven vents are disposed in the attic, when certain atmospheric conditions exist insideattic 22, the power driven vents force air fromattic 22, and fresh air is drawn through theduct assembly 20 into the attic 22. The fresh air is forced into thestagnant area 23 of the attic 22 through the holes 51 defined in the perforatedportion 44 of theduct 40. - Alternatively, the
duct 40 may include a plurality of unperforated portions and a plurality of perforated portions such each of the perforated portions may be disposed in one of a plurality ofstagnant areas 23 of the attic 22. Specifically, theduct assembly 40 may include a plurality of unperforated portions and a plurality of perforated portions arranged in alternating relationship with the unperforated portions. - The
duct assembly 20 may be installed during the construction of a building or may be installed to currently existing buildings. It should be appreciated that theduct assembly 20 is not limited to residential or commercial buildings, but may be mounted in any structure to allow for the exchange of air between an interior of the structure and anexterior 25 of the structure. - For exemplary purposes,
FIGS. 1-3 show an embodiment of theduct assembly 20. In this specific embodiment, theduct assembly 20 includes theboot 38 connected to thefirst vent 34, specifically agable 28 vent, a firstright angle elbow 54 connected to theboot 38, a firstunperforated portion 48 of theduct 40 connected to the firstright angle elbow 54 and extending to theceiling 32 of thebuilding 24, a secondright angle elbow 60 connected to the firstunperforated portion 48, a secondunperforated portion 50 connected to the secondright angle elbow 60 and extending to an eave 56 between theroof 30 and theceiling 32 of thebuilding 24, a thirdright angle elbow 58 connected to the secondunperforated portion 50, and a first perforated portion 52 connected to the thirdright angle elbow 58 and extending along the eave 56 between theroof 30 and theceiling 32 of thebuilding 24. The diameter of theduct 40 depends upon the length of the building, the size of the attic, and other factors. Theholes 46 defined by the perforatedportion 44 of theduct 40 are preferably spaced one inch apart and face theroof 30. - The invention has been described in an illustrative manner, and it is to be understood that the terminology which has been used is intended to be in the nature of words of description rather than of limitation. Obviously, many modifications and variations of the present invention are possible in light of the above teachings, and the invention may be practiced otherwise than as specifically described.
