Cladding is a layer of a building frame structure and it mounted on the outer surface of a structure
In the context of a framed building the primary objectives of the cladding system itself are:
i) Provide an enclosure to the structure which will give the necessary protection against the elements

ii) Exploit dry construction methods where possible, including the use of off-site prefabrication
iii) Impose the minimal additional dead load onto the frame
iv) Enhance the architectural concept/appearance of the building

Strength to support its own self weight between points of supports or fixings to the structural frame.
Stability against lateral wind pressures.
Allowance for differential movements between itself, the structural frame and other adjacent building elements.

Structure wind bracing arrangements.
Ability to cater for frame movements

Resistance to wind, rain and other forms of precipitation (cladding and joints).

Durability, freedom from maintenance, and ability to weather well.

Avoidance of problems arising from ‘cold bridging’ and from surface and interstitial condensation.
Minimisation of air leakage

Restriction of flame spread to internal and external surfaces and within voids

Prevention of sound originating in one part of the building being transmitted to other areas via cladding members/elements.

The need to respond to the context within which the building is situated.
The need to satisfy the aesthetic aspirations of the client. (Weathering characteristics/durability of materials).
