An exterior wall typically forms part of the building envelope and so separates the accommodation inside from that outside. Its main function is to provide:

* Environmental control – mediating between indoor and outdoor climates.
* Weathering – providing resistance to the weather determines durability and appearance.
* Security – although this will also depend on window and door openings.
* Fire control – preventing fire spread either on the wall surface or in its cavities.
* Aesthetics – along with the roof, determines to a large extent the external appearance of the building.

In loadbearing construction such as masonry, the exterior wall may also provide support to the combined dead, imposed and wind loads of the roof and floor construction and convey them to the foundations. This is in addition to the wall’s own combined loads.

In a framed structure, the external walls are usually non-loadbearing and are therefore relieved of any upper floor and roof loadings. However, they are normally self-supporting and are designed to resist wind loads, prevent the spread of fire and accommodate thermal movements.

= Materials =

Exterior walls can be made of a wide variety of materials either singly or in combination with other materials. These can include:

* Masonry laid in courses with mortar (loadbearing or facings)
* Concrete
* Timber
* Metal cladding – requires a framework for support
* Glass, metal or timber panels
* GRP/GRC cladding.
* Terracotta.

Various construction systems can be used to build an external wall, including:

* Loadbearing – using bricks and blocks, or reinforced concrete. Timber is used for log cabin construction. Exterior walls form part of the structure.
