Abstract

The present invention broadly relates to insulated window shades, and more particularly to window shades of various designs which incorporate an aerogel blanket.

1 . An insulated window shade comprising:
 a shade cloth; and   a flexible blanket of aerogel material affixed to the shade cloth.   
     
     
         3 . The insulated window shade as set forth in either  claim 1  wherein the shade is pleated or folded to form either a pleated or a roman window shade.
