The concept of a ventilated façade consists of keeping the curtain wall separated from the supporting wall to allow natural ventilation through an air cavity. Air circulation is essential so that natural stone can release moisture more quickly, preserving its original tone for longer. In this way, salts and minerals from the supporting wall do not migrate into the stone, keeping it clean and free from stains.
Ventilation helps maintain a controlled temperature, reducing the effects of thermal expansion in the stone. Mechanical systems must be studied and adapted to different types of stone, allowing the installation of thinner thicknesses and larger panels. The main advantages of this system are energy efficiency, low maintenance costs, increased building longevity, and cladding durability.
