ABSTRACT:
A curtain is provided for use across the doorway of a garage, or the like, through which vehicles may pass easily but which substantially blocks out ambient weather conditions. The curtain provides a barrier which retains building heat during the winter and cool air during the summer and reduces entry of cold air in the winter and warm air in the summer. The curtain is comprised of a single main panel suspended across the upper portion of the doorway and a plurality of a relatively narrow, overlapping strips suspended from the lower edge of the fixed panel. Wide strips and/or one or more layers of narrow strips are provided at the sides to reduce heat transfer through the sides of the curtain. A breakaway line extends across the mid portion of the doorway opening to prevent the curtain from billowing inward in the event of unusually high wind gusts.
