A COMPOSITE INSULATING PANEL

摘要

A composite insulating panel comprises an external sheet, an internal sheet, and an insulating body between the sheets. The external sheet has a first longitudinally extending raised side underlap projection at one side and a side overlap projection on the opposite side of the panel with a substantially flat portion extending between the projections. A photovoltaic solar collector is mounted to the flat portion of external sheet. The solar collector comprises a photovoltaic sheet and a protective translucent cover for the photovoltaic sheet. A first adhesive layer is provided between the photovoltaic sheet and the translucent cover. A second adhesive layer is provided between the underside of the photovoltaic sheet and the external surface of the composite panel upper or external sheet.
