ABSTRACT:
A gasket assembly for use with a ventilation control apparatus in a building ventilation system in a building. The building ventilation system includes inlet and outlet vents and a fan. A plurality of generally narrow continuous openings are formed in a ceiling portion of the building for introducing a ventilating air flow from a first chamber into a second chamber of the building. Air flow through each opening is selectively controlled by a movable baffle device for regulating air flow through the opening into the building. The movable baffle devices are positioned over a ventilation subject, for example a livestock cage, to cooperatively create a desired ventilating air flow pattern in combination with neighboring movable baffle devices. The gasket assembly is employed with the movable baffle device to provide an extremely uniform yet suitably fresh minimum air flow through the building. The gasket assembly includes a dam portion and a curtain portion. The curtain portion channels air flow from the opening to a reduced horizontal opening defined by the dam portion, ends of the curtain portions and the movable baffle.
