Abstract
Various embodiments of the present invention provide an insulated structural panel including a superinsulating, desiccant-filled, vacuum-sealed insulating panel sandwiched between a pair of composite panels. The composite panels are configured to impart structural strength to the panel without introducing heat transfer pathways through the vacuum-sealed insulating panel. The desiccant material disposed within the vacuum-sealed insulating panel is capable of absorbing moisture within the vacuum established within the vacuum-sealed insulating panel and thereby reducing the degradation of the vacuum-sealed panel's insulating capacity.
Claims22
An insulated composite panel assembly comprising:
- a first composite panel;
- a second composite panel disposed substantially parallel to and spaced apart from the first composite panel;
- and
- a vacuum-sealed insulating panel operably engaged between the first composite panel and the second composite panel, the vacuum-sealed insulating panel comprising a desiccant material disposed therein.
