- Non-load bearing lightweight façades are facades built with light industrial materials, on a building frame as opposed to a traditional construction in concrete veil and filling by masonry or other.
- Lightweight non-load-bearing façades are carried by the structure of the building, which is called the supporting structure.
- the supporting structure is based on the foundations.
- Light non-load bearing facades are attached to the supporting structure via a so-called primary framing framework.
- Lightweight non-load-bearing facades can themselves include, when necessary, a framework that is called a secondary framework, attached to the primary framework.
