VENTILATED FAÇADES (OR RAIN SCREEN SYSTEMS)
THE MAIN REASONS FOR CHOOSING THEM
The growing need for sustainable development as a solution to the environmental emergency, the reduction of energy consumption in buildings, the application of new technologies in construction and the need to upgrade existing assets, are all issues that can be addressed by means of the ventilated façade.
In its narrowest definition, a ventilated façade is a dry-built screen in which the interspace between the cladding and the wall is designed to allow the natural flow of air using the "chimney effect". But in our interpretation it is not merely an internal - external diaphragm but rather a dynamic filter that is the expression of an architectural "language" capable of properly satisfying the needs of well-being and comfort in a sustainable manner.
The defining characteristic of a "ventilated façade system" is the chamber created between the wall and the external cladding that allows the air to move.
Having spent decades analysing the behaviour of air chambers we have adopted the principle of the open joint façade. This creates a more regular and continuous ventilation than with sealed joint systems, perfectly regulating the air heating-cooling cycle.
In addition, using this method ensures that the circulation of the air remains constant and is not interrupted by any architectural features.
- PROTECTION FROM THE ELEMENTS
A Ventilated Façade is a system for protecting walls that has high breathability. This allows moisture produced within the building to disperse externally, without encountering obstacles or barriers, thus keeping both the walls and the insulating panels in the ideal condition for insulating and preserving the structure.
The Ventilated Façade is a thermo-hygrometric shield that significantly restricts the entry of the elements and of pollutants, both of which cause degradation of the building fabric.
- THERMAL PROTECTION
The Ventilated Façade is the most effective solution for ensuring compliance with energy efficiency standards, whether in new constructions or renovations.
The Ventilated Façade creates a "heat shield" for the building to which it is applied, protecting it from heat through the constant circulation of air at ambient temperature that washes over the outer surface of the insulation.
In summer conditions it results in a phase shift of the heat wave: the heat penetrates the interior of the building less and at times when the ambient temperature is lower.
In winter conditions, it increases the time it takes for the walls to cool.
- SOUND INSULATION
The Ventilated Façade makes it possible to comply effectively with sound insulation regulations.
Being a multi-layer system, it has a higher noise absorption effect; this results in continuous and uninterrupted insulation that easily eliminates acoustic bridges.
The correct choice of the insulating material and the correct design of the enclosing envelope can give the building a high level of sound insulation at a reasonable cost of construction.
