Patent Images
1. A composite insulating panel comprising:
- a first sheet having an inner surface and an outer surface;
a second sheet having an inner surface and an outer surface;
an insulating foam core extending from an inner surface of the first sheet to an inner surface of the second sheet;
the insulating foam core having at least one heat exchange conduit extending longitudinally therethrough from one end of the panel to an opposite end of the panel for passage of a heat exchange fluid;
at least one of the sheets including at least one outwardly directed raised projection which extends longitudinally along a length of the panel, the projection having an internal open mouth, the raised projection having an external surface and an internal surface, the internal surface of the projection defining a first portion of the heat exchange conduit; and
an internal barrier membrane between the internal open mouth of the projection and the foam core, the barrier membrane extending outside a plane of the open mouth of the projection and extending into the foam core to define a second portion of the heat exchange conduit.

Abstract
An insulating panel includes a first sheet, a second sheet, and a body of insulating foam between the sheets. The foam has a plurality of longitudinally extending conduits through which a heat exchange medium such as air is circulated. A barrier is used to create an enlarged void space for air circulation. The barrier is located below profile crowns to prevent foam from entering the crowns and to create additional foam-free voids below the crown. Heat transfer efficiency is increased.
