for copper cladding a building:
* seamed-cladding
Cladding is an outer layer of material covering another. It may refer to the following:
*Cladding (boiler), the layer of insulation and outer wrapping around a boiler shell
*Cladding (construction), materials applied to the exterior of buildings

(typically 0.7mm thick copper sheet on the facade): max 600mm by 4000mm 'seam centres'.
* shingle-cladding (typically made from 0.7mm thick copper sheet): max 600mm by 4000mm 'seam centres'.
* slot-in panels (typically made from 1.0mm thick copper sheet): max 350mm wide for 1.0mm, by nominal 4 m length.
* cassettes (typically made from 1.0mm up to 1.5mm thick copper sheet): largest-format cladding elements, more subframing is needed: can be 900mm x nominal 4000mm length.
When selecting size of a cladding element, take wind-loadings into account, and also consider the standard sizes available of the sheet (or coil) pre-material, to minimise material wastage through off-cuts. This helps to reduce costs.
The choice of which system to use depends on the aesthetic effect required, and building geometry
Geometry (; ) is, with arithmetic, one of the oldest branches of mathematics. It is concerned with properties of space such as the distance, shape, size, and relative position of figures. A mathematician who works in the field of geometry is ...
can also have an influence on the choice.
Copper cladding is very durable, lightweight compared to other materials and techniques, and at the end of the building life is also 100% recyclable
Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the p ...

Depending on metal prices, copper may be a very cost-effective cladding and roofing material. With good building design, materials choice and craftsmanship Workmanship is a human attribute relating to knowledge and skill at performing a task. Workmanship is also a quality imparted to a product. The type of work may include the creation of handcrafts, art, writing, machinery and other products.

, copper roofing or facade cladding may be cheaper than slates or concrete
Concrete is a composite material composed of fine and coarse aggregate bonded together with a fluid cement (cement paste) that hardens (cures) over time. Concrete is the second-most-used substance in the world after water, and is the most wid ...

-free and lightweight nature of the cladding.
Because the UK code of practice for "hard metal" cladding (as opposed to lead cladding) is quite old – CP143: part 12 (1970) – the major manufacturers have to provide detailed technical advice and information for architects, designers and builders, and cultivate skilled installers with years of experience to draw on.
Typically, an installer of hard metal roofing and cladding must put in around 8–10 years on-the-job in order to achieve a respectable experience on a work site.
