Abstract
An aerator pad assembly having an aeration pad with a number of cutouts forming a shaped perimeter, is provided. The aeration pad may include a number of supports providing which provide air flow paths between the aeration pad and an associated aeration panel. A gasket may be disposed about the shaped perimeter, the gasket having a plurality of protuberances with fastener openings included, and the protuberances preferably cooperate with the cutouts to form a generally continuous interface between them. In one embodiment, a notched opening within the gasket is provided at the generally continuous interface with the shaped perimeter at least partially occupying a portion of the notched opening. In a particular embodiment, the gasket may be molded onto the aeration pad. In another embodiment, an adhesive material may be provided to form the attachment. In yet another embodiment, stitches of thread may attach the gasket and the aeration pad. A sealant material may also be provided at the generally continuous interface to seal voids between the gasket and the pad.
