A heat-transfer panel or sheet material comprises a woven wire mesh core of high thermal conductivity metal, for example copper or nickel, embedded in a closure layer of plastics material, for example a urethane, so that the mesh and the closure layer extend in the same longitudinal direction. The mesh core defines a nodal network and the nodes are located at or closely adjacent the outer surfaces of the closure layer so that satisfactory heat transfer between opposite sides of the panel is achieved over the whole outer surface area of the panel by virtue of heat conduction by the mesh core. |
