Abstract
An insulating window shade assembly includes a first roller carrying an insulating shade and a second roller carrying a cover fabric. The shade and cover fabric are supported in essentially face to face relationship, and their bottoms are secured together by a Velcro-type fastener. The cover fabric conceals the insulating shade, it may be removed from the shade for cleaning or may be changed and it may be adjusted for smoothness and to compensate for any stretching which occurs in the materials.
