ABSTRACT:
A thermally efficient window shade that folds into attractive pleats in the raised position. The shade is fabricated from a laminated insulating material composed of encapsulated air bubbles in combination with one or more skins. The shade folding properties are obtained by slitting the laminate partially through the laminate at predetermined locations. The disclosure includes modified versions of the laminated insulating material as well as shade configurations wherein numerous three-sided pockets are formed by the shade to provide small regions of stagnant air. The disclosure further includes apparatus for efficiently slitting a continuous web of the laminated insulating material.
