Benefits
Advantages of the ventilated facades
Outdoor tiling realised with the use of ventilated walls brings significant benefits to a building.
Firstly, the quick disposal of condensation and dampness, allowing greater duration in time of the structures thanks to the healthier and dryer conditions that the ventilated facade, unlike the traditional outdoor tiling systems, manages to guarantee.
The high passive acoustic protection value is another advantage linked to ventilated walls and due to the sound insulation capacity of the ceramic slabs and of the insulating layer.
Thanks to the ventilated facades the buildings maintain a correct heat insulation, assured by the empty airway and by the insertion of the insulating layer, usually applied directly on the supporting wall. It is necessary that such layer is correctly laid and without any defects, to avoid condensation and mould phenomenons (main cause of the premature deterioration of walls).
The effect of high thermal inertia, meaning maximum use of the ability to keep the wanted thermal conditions within the building (hot during winter and cool during summer), is particularly efficient during the warmer months, in that the natural ventilation system of the airway manages to dispose most of the solar rays reaching the walls.
A correct and balanced permeability to steam is had with ventilated walls, allowed by the fact that it does not pose barriers for the dispersing of steam and that the induced ventilation favours its disposal.
The ventilated facades result being a lot more efficient for the protection from water that, together with atmospheric gases, it is one of the main sources of deterioration of buildings, also due to the forming of ice during the colder periods of the year. The latter inconvenient is however obstructed by the features of the same wall: the outside temperature must drop a few degrees below zero before the value inside the airway also drops below that threshold and ice in this way forms.
The highest economical investment requested for the installation of a ventilated wall therefore brings significant benefits to a building, guaranteeing greater living comfort, a high energy saving, a greater resistance to deterioration and the value preservation of the premises in time (in fact, the ventilated facade protects the wall).
All these features ensure that the ventilated wall can be considered as an excellent solution for the living wellbeing of the building and the best that can be obtained today in terms of energy and maintenance saving, in view of the protection supplied to the structure of the building.
The ventilated facade is also able to couple two qualities that are usually in contrast: the ability of protecting the wall from meteoric water infiltrations at the same time favouring transpirability to the steam.
The latter is in fact the main feature of the ventilated wall and is favoured by the created natural ventilation (which also gives the name to the entire system, in that predominant and qualifying element).
As previously mentioned, the airway ventilation can happen in two partially different ways:
1. By means of the ”chimney effect”. The outdoor tiling must be continuous and without cracks, therefore the joints between the slabs must be accurately sealed. In this way, the air present inside the airway, as it becomes warmer, it tends to rise exiting from the upper openings and creating a ventilation that avoids overheating of the walls (also because the ceramic tiling prevents the building being hit directly by solar radiation). During the winter period, this effect is a lot milder and, also thanks to the coupling of the insulating layer (usually made of glass/rock wool or polystyrene), a just as valid insulation against the dispersion of heat from the building is obtained.
2. When the ceramic slabs composing the tiling are not sealed, as in most cases, to the chimney effect also overlaps the “pressure - depression” created by the breeze and by the wind blowing on the walls. Studies carried out in the North European countries have established that this system is as valid as the first one. Obviously, in view of the lower cost, this is the system mainly used in the building sector.
