Panelling
Panelling is a millwork wall covering constructed from rigid or semi-rigid components. These are traditionally interlocking wood, but could be plastic or other materials.
Panelling was developed in antiquity to make rooms in stone buildings more comfortable both by insulating the room from the stone and reflecting radiant heat from wood fires, making heat more evenly distributed in the room. In more modern buildings, such panelling is often installed for decorative purposes. Panelling, such as wainscoting and boiserie in particular, may be extremely ornate and is particularly associated with 17th and 18th century interior design, Victorian architecture in Britain, and its international contemporaries.
Wainscot panelling
The term wainscot originally applied to high quality riven oak boards.Wainscot oak came from large, slow-grown forest trees, and produced boards that were knot-free, low in tannin, light in weight, and easy to work with. It was preferred to home-grown oak, especially in the Netherlands and British Isles, because it was a far superior product and dimensionally stable.
The Oxford English Dictionary states that it derives from the Middle Low German wagenschot as well as wageschot or 'wall-board'. Johnson's Dictionary defined it thus:
A 'wainscot' was therefore a board of riven oak, and wainscoting was the panelling made from it. During the 18th century, oak wainscot was almost entirely superseded for panelling in Europe by softwoods, but the name stuck:
Today the term wainscot refers commonly to the different treatment of the lower part of the wall ; see also dado.
