Abstract
An inflatable cover is constructed with a base sheet to which is attached an overlaying material sheet in order to form an inflatable structure. There is an opening to admit warmed air into the inflatable structure. A plurality of apertures open through the base sheet, into the inflatable structure for the purpose of exhausting warmed air therefrom, through the base sheet. The plurality of apertures vary in density toward an edge of the base sheet for the purpose of establishing various temperature profiles with respect to the inflatable cover. In a particular embodiment, the density of the apertures increases toward the edges of the base sheet, from the center of the inflatable cover.
