The component comprises a thermally insulating material 125 and at least one strengthening bar 120 sandwiched between first and second layers 100. The thermally insulating material may be a plurality of elongate foam blocks with uniform cross sections, which may locate with an interference fit in elongate cavities formed by the layers and strengthening bars. The strengthening bars may be cross laminated wood whose grain may extend along its length, and which has a greater stiffness than the thermally insulating material. The first and second layers may be cross laminated wood. The component may form a door core, panel, rail or stile. Also claimed is a door 20 comprising the component. The door may have a wooden frame 150. Also claimed is a method of manufacturing the door component comprising arranging the first and second layers and strengthening bars to form a cavity into which is pushed an elongate block. Also claimed is a method of manufacturing a joint-less door. |
