ABSTRACT:
Strips of heavy transparent plastic are suspended in a doorway with the edge of each strip overlapping an adjacent strip to completely close the doorway in a manner which minimizes heat transfer through the doorway while permitting hand-free movement through the door. The strips are suspended by loops formed on the upper end of each strip. Various loop constructions and overlap arrangements are disclosed to facilitate the mounting of the strips.
