The term 'cladding' refers to components that are attached to the primary structure of a building to form non-structural, external surfaces. This is as opposed to buildings in which the external surfaces are formed by structural elements, such as masonry walls, or applied surfaces such as render.
One of the most common methods of cladding buildings is through the use of timber softwoods, such as western red cedar. This type of wood is relatively knot-free and has a natural resistance to decay and moisture. It can be readily stained or painted and altered to create a range of profiles.
Thermally-modified timbers are also being used such as Kebony, Keywood, Platowood and ThermoWood. These softwoods are heated to high temperatures which removes moisture and resins, resulting in a stable and durable material.
Some of the most common laying styles are:
- Square edge: Square-edged boards of a uniform thickness, usually between 12-18 mm, with widths of boards vary from 125-225 mm.
- Feather edge: Boards are tapered across their width, producing a rustic, rural aesthetic.
- Shiplap: Has a shaped front face and profile so that the top of each board fits behind the bottom edge of the adjacent board, providing a neat finish.
- Tongue & groove: Have a flat face and, in which a groove covers the tongue of the board below. This produce a uniform look that suits contemporary houses.
