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 hea t exchange medium such as air is circulated. A barrier (10) is used to creat e 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 creat e additional foam - free voids below the crown. Heat transfer efficiency is increased. |
