What is a ventilated facade?

A ventilated facade is a dry-installed exterior building envelope system. It can be installed on new buildings or on buildings undergoing renovation.

A ventilated facade gives the building a space between its perimeter wall and the exterior cladding, which allows the facade to breathe (ventilate) and thus prevents the accumulation of humidity all while respecting the highest insulation standards.

Why should you choose a ventilated facade?

A ventilated facade in natural stone offers excellent thermal insulation, reducing the building’s energy footprint. In summer, it reduces indoor temperatures by reflecting light. In winter, on the other hand, it keeps the heat in and combats humidity.

Thanks to its thickness, a ventilated facade is also a natural sound insulator.


Its primary purpose is to moderate the exchange of cold, heat and air that circulates between the interior and exterior of the building. In this manner, the supporting wall is protected from both the cold and heat, resulting in energy savings.
