<p>The building panel 18 comprises at least one sheet of an electrically-conductive polymer 20. In use, the building panel defines at least part of a habitable space within a building, such as a room. The at least one sheet is heated by the application of electrical power, thereby heating the space. The electrical power may be mains electricity 12 delivered via a fused switch 14 and transformer 16. The panel can be used as part of a wall, floor or ceiling. The panel may comprise two plasterboard members (32 and 40, figure 2) that together define an enclosed space in which a plurality of electrically conductive polymer sheets are received, each of the sheets being webbed (figure 4) and comprised of particulate carbon black dispersed through polymeric material. The enclosed space can allow for expansion of the sheets. A set of third plasterboard members (54, figure 3) can be used to define a plurality of enclosed spaces within the panel. The sheet may include a polyester fabric reinforcement mesh embedded therein. A method of forming the panel is also claimed.</p> |
