The facade corresponds to the frontage of a house and this one can show different technical characteristics, according to the plans of construction. The facade can be a carrier but here we will approach the facades non-bearing or so-called light. What are their specificities and their usefulness?
What is a non-load bearing facade?
Also called light facade, a non-load bearing facade does not contribute to the robustness of the structure unlike the load-bearing façade which guarantees the solidity of the building. Moreover, the non-load bearing or light facades are usually made with light materials, with a rather low mass: less than 100 kg / m².
It should be noted that the portage of a light facade is provided by the structure of the construction which can be wood, metal or concrete. It is based on a primary framework.
Because of its lightness, the implementation of such a non-bearing facade is fast. Note that this type of facade most often equips buildings for industrial or commercial use. However, there is one caveat: the insulation of the wall (whether thermal or phonic) is not optimal and the costs to maximize it are quite high.
In what materials is a light facade?
Insofar as the non-load bearing facade is not part of the solid structure, it is therefore possible to bet on lightweight materials. Most of the time, the support is metallic, with filling elements that are integral with the latter. In professional jargon, it is a question of "curtain facade". Among the filling elements, there is a watertight wall and among the star materials, there is steel or sheet metal. But modern buildings can also be decorated with glass.
In addition to the sealed wall, it is also necessary to consider the internal wall which ensures, for its part, a secondary filling. This element ensures the insulation of the construction. The material used must be light, but also resistant and insulating. Most often we use the fiberglass, mineral wool, polystyrene or wood fiber.
Finally, there is the inner wall at the level of the house which provides the same protection of the insulation. In practice, it is a light partition, usually plywood, agglomerate or plaster. This support usually accommodates the interior wall covering (wallpaper, plaster, paint...).
