Abstract
A retractable cover for an architectural opening is described that includes a honeycomb insulating panel wherein each cell of the panel has multiple layers of material formed by embedding tubular cells. In this manner, the retractable cover may be formed that has superior insulating or light blocking capabilities in a volume comparable to one with a honeycomb panel made of tubular cells having a single layer of material. The panel of the resultant cover is formed by attaching a plurality of embedded tubular cell units, wherein each embedded tubular cell unit comprises at least one side having multiple layers of material.
