A wooden door comprises a main section 2 and a plurality of substantially horizontal ledges. The ledges are fixed to the main section and have a wood grain 10 extending substantially horizontally. At least one of the ledges extends across a major portion of the door width, terminating in a hinge attachment region comprising additional ledge section 6 having a grain extending in a different direction 14 to the gain of the main portion of the ledge, preferably at right angles. Preferably or alternatively to the grain direction feature, deformable layer (24, figure 3) is provided between the main and additional ledge sections, which is able to accommodate differential expansion between the ledge sections. Preferably, deformable layer (24) is synthetic rubber or foam. The additional and main sections may be joined by a biscuit 22 or tongue and groove joint. The width of the additional section is preferably large enough to accommodate screws for a butt hinge, and is from 10 and up to less than 25 percent of the width of the door. An additional ledge portion is preferably provided at both ends of all ledges of the door. |
