Abstract
Abstract A lightweight cover for a shaped object such as an automobile for protecting the object from the environment comprising a plurality of panels of lightweight, impermeable sheet material having the edges joined to form an enclosure. The sheet material is preferably a laminate of a film of reflective metal between an outer layer of transparent resin such as Mylar or polyethylene and an inner layer of resin, preferably color coded. The laminate may optionally contain a layer of scrim reinforcement. Water trapped between the cover and the surface of the object is selectively exhausted by means of vents having a flap which opens in response to gas pressure developed on evaporation of the trapped water vapor and normally remains closed to prevent entry of rain, dust, sap or other substances harmful to the finish of the automobile stored under the cover.
