External cladding and building facades are the outermost layers applied to a vertical structure of a building to give it adequate resistance to mechanical stress and atmospheric agents, as well as an aesthetic finish.
Facades are, in a certain sense, the building’s business card and it is easy to understand why aesthetics are often one of the main reasons for choosing one cladding material over another.
But in addition to defining the appearance of a building, exterior wall finishes must also perform other functions, such as building protection, and consequently guarantee certain characteristics.
Metal claddings for facades have the advantage of being prefabricated products to which any shape can be attempted thus lending themselves to the creation of light and weather-resistant curtain walls.
The most used materials are steel, aluminum, copper and zinc, available in the form of panels, shingles, but also nets.
Sandwich panels, or panels, are also part of this family of coatings
internally insulated boxes, to create curtain walls with excellent insulating performance.
Metal coatings are also often used for the construction of ventilated facades, or facades in which a ventilation chamber is inserted between the structure and the finish , thanks to a special framework.
The realization of these coatings requires careful planning that correctly defines the materials to be used, the dimensions, the surface finishes and the types of joints of the slabs.
