An insulating panel (1) comprises a first sheet (2), a second sheet (4), and a body of insulating foam (5) between the sheets (2), (4). The foam (5) has a plurality of longitudinally extending conduits (7) through which a heat exchange medium such as air is circulated. A barrier (10) is used to create an enlarged void space for air circulation. The. barrier is located below profile crowns (3) to prevent foam from entering the crowns (3) and to create additional foam - free voids below the crown. Heat transfer efficiency is increased. |
