Wood is, along with stone and earth, one of the principal materials used in the construction of buildings, and particularly older buildings. The principal varieties used are oak, poplar and beech, known as hardwood in UK. Spruces and pines(softwood in UK) are also much used, especially in new-build. It is important to have some understanding of the nature of wood, its uses in the older house and some sympathy for its virtues as well as its limitations.
Wood is used in a wide variety of applications, and the most important of these are the support structure for floors; the roof timbers and associated work; and the interior finishing timber. Timber is also used in the construction of interior walls and in many areas in the construction of supporting walls.
There are three timbers commonly found in older buildings in France, namely oak, poplar and pine. Other timbers are often found as parts of outhouses and sheds.
