When using a thermoplastic material, the system may include means (5,9) for controlled cooling said liquid material excluding said intended rooms, below the melting point. When using a thermosetting material the system may include means (5,9) for controlled heating the liquid material, excluding said intended rooms. Moreover, means (6) are provided for driving out the liquid material within said intended rooms by means of air or another gaseous medium or by means of water or another liquid medium. In the product some rooms or conduits may comprise a conductive layer or structure, e.g. applied upon the surface of the relevant room or conduit, in/on a foam structure (18) or upon the surface of an auxiliar carrier (20) within the relevant room or conduit.</p> |
