The generic facade described is a curtain wall, an assembly consisting of a vertical and horizontal framework of aluminum profiles, assembled and anchored to the building structure, with transparent or opaque fillings to form a continuous and lightweight envelope that, alone or in conjunction with the construction, provides all the normal functions of an exterior wall, the closed and covered, but does not contribute in any way to the stability of the building structure.

Designated "grid facade", the lightweight load-bearing framework is composed of elements (cross members and uprights) assembled on site, anchored at the slab nose, on the height of one or more floors and then completed with prefabricated infill.

Justified in accordance with the European product standard NF EN 13830 and installed vertically with a maximum angle of 15° both towards the outside and the inside, it meets the requirements of NF DTU 33.1 unless specifically requested.

The function of the studied system is among other things to let light through. However, a facade fulfils a multitude of functions and must have characteristics that ensure the comfort level of the building's occupants.

The indication of the variation in the percentage of transparency represents the transparent glass surface for the same module

The system functions are as follows:
- limit heat loss, sound transmission and air flow,
steam flow and condensation formation;
- let the sun's heat penetrate in winter, while ensuring summer comfort.
- protect against bad weather, such as rain, snow and wind;
- contribute to limiting the spread of fire in accordance with regulations
applicable to the building;
- provide ventilation and air change when required;
- ensure safety against falls for occupants;
- ensure smoke extraction if required;
- allow the entry of emergency services (firemen) when required
