Flooring and wall cladding is a type of decorative covering intended to make look like it is made of a different sort of material than it actually is. Some of the most common examples are on the outside of buildings, but cladding can also be an artistic element in interior decorating. It's usually non-structural, which means that it doesn't impact the stability or integrity of a building's architectural core. In most cases it's designed to be permanent, and it may provide benefits like insulation and waterproofing. It can be made out of almost anything, but various metals, stones, and composite materials are the most common.
