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