The ventilated facade is a solution that is often used for covering building facades. A way to enhance the aesthetic but also the functional side by promoting the breathability of the building and therefore increasing its performance.
In general, a facade plays an important role in the context of a building: it acts as a barrier between the external and internal environments, thus determining the level of insulation and, at the same time, acting as an architectural aesthetic element. When creating a facade, the aspect of protecting indoor environments must be taken into consideration, therefore reducing energy consumption, as well as the aesthetics of the building itself.
Among the many solutions that are adopted there is the ventilated facade, which offers multiple advantages both in terms of energy savings and from the point of view of the architecture of the building.
What is the ventilated facade?
The ventilated facade of a building is an external cladding system consisting of several layers that can be adapted to both new buildings and existing buildings with a facade redevelopment work. The layers that make up a ventilated facade are:
- Insulating layer, on the external perimeter wall;
- Cavity for ventilation;
- Support structures where to anchor the external coverings;
- The actual external coating.
A technology that can guarantee high performance, which is why it is increasingly used in architecture for building facades. The advantages are recorded in terms of thermal, acoustic insulation, protection of the structure and enhancement of the building’s aesthetics. Obviously, these performances are guaranteed when using materials of a certain type, especially with regard to the external cladding of buildings.
Mechanism is quite simple: an empty space is created between the wall and the external cladding thus promoting the breathability of the building itself and significantly improving energy efficiency, as well as comfort.
How ventilated facades work
It can be installed on any building facade using supports that guarantee a mechanical anchoring system for the cladding, always leaving an air chamber between the external facade and the load-bearing structure of the building. This means that the building has high performance both in the summer months, as part of the heat will be reflected outside, and in the winter months.
It is important for a good result the external covering panels to be applied on the facade with anchoring systems to form a continuous layer. They are elements that are specifically created for ventilated facades that allow you to create continuous ventilation (the so-called chimney effect) in the empty space of the air chamber.
Materials must be of high quality, as in the case of Cladia panels made with Ductal, to guarantee high resistance to temperature changes, external stresses, chemical attacks and smog. The result will be a more insulating facade, suitable for problems such as humidity, infiltrations, detachments.
The ventilated facade is also an ideal system for an energy redevelopment work on existing buildings, giving a new skin to a building and also allowing maximum freedom of expression for the architect who works. All this to also guarantee a remarkable aesthetic result.
