Wall cladding is a type of decorative covering used on building
exteriors. Though usually non-structural in nature, it may be
functional in addition to decorative. This can include a degree of
water-proofing, a barrier against the wind, or other protections.
Cladding can take a number of different forms, be made from many
different materials, and is often used to create a decorative
building facade. Some of the popular materials for cladding include
various metals, stone, and composite sidings.
