Support element formed by a two-dimensional component that, after fitting, closes the facade and defines its outer image. Depending on the degree of complexity of the panel, especially with regard to the design of the joints and the sealing mechanisms, these are of the following types:
- External panels that add supporting layers on the interior. They are usually associated with a single material and technique and need a seal or creation of the joint in situ (concrete or GRC - glass fiber reinforced concrete panels-).
- Complete panels that are brought to the site with all their layers and thusly all their functions.
These include a variety of subtypes according to the technology used.
