<p>The panel has two identical shaped covers (1, 2) of steel or other conducting material bent at the ends to form tongue and groove type joints, and it is filled with insulating material by injection moulding. The thermal bridge between the heat conducting outside parts of the panel is cut by the form and shape of the joint which allows for a continuous thickness of insulating material through the centre line of a series of adjacent connected panels. The metal cover and joint shape make the panel damage resistant and cheap to erect.</p> |
