Building cladding is the exterior skin, or envelope of a
building, and includes all moisture barriers and siding
materials used to cover the outside of the structure.
While the term cladding is widely used in Europe and
Australia, these exterior finish materials are typically
known as siding in North America.
Cladding can serve both a decorative and a functional
purpose. It is used to complement the architectural
style of the building while also offering protection from
rain, wind, snow, and other outside elements.
Building cladding can also add insulation to the
structure while minimizing sound transmission through

Has exterior cladding attached

large panels which span one or

Example: precast concrete or
steel-stud frames welded or
bolted to attachments built into
the structural frame.

Cladding material is installed between exterior floor slab edges
and the exposed exterior columns of the structural frame being
the identifying feature.

2. Differential movement between structural frame and cladding

Aluminium composite panels (ACP) &
extruded aluminium are used. They are light

nature, have high strength-to-weight ratio and
come in diverse colours and finishes.
Copper, another type of metal cladding is

Brick cladding is designed to

the internal framing of the
building. This reduces the
risk of damage to the
framing caused by mold and
mildew. It also keeps the
interior dry and pleasant.
Timber cladding is done in dry areas and hilly areas.
Effective temperature insulator as it keeps the interior cool.
Fitted by tongue and groove joints mostly.

Available in variety of colours.
Plasterboard is generally used to clad internal walls. It is a pliable
material that can be easily cut with a craft knife. Plasterboard should
be cut a half-inch shorter than the wall and should be nailed onto the
wall framework. Jointing tape should be placed over the joints of
plasterboard to give a smooth finish.
Rain screen cladding includes an outer skin (of rear-ventilated) cladding
attached to an existing/new building. While the outer layer takes care of
the exterior weather elements, the inner layer provides thermal
insulation and carries the wind load, hence conserving energy.
With the advent of green buildings, the trend of green walls have
come into place. It can be installed both in the interiors and the
Application of aluminum or vinyl sheeting ,cut and
