The ventilated facade system is a form of double-wall construction that uses an outer layer to keep out the rain and other atmospheric influences and an inner layer to provide thermal insulation, prevent excessive air leakage and carry wind loading. The outer layer breathes like a skin and protect the inner layer which reduces energy losses.
The structural frame of the building is kept absolutely dry, as water never reaches it or the thermal insulation. Evaporation and drainage in the cavity space between inner and outer layer removes water that penetrates between panel joints.Water droplets are not driven through the panel joints or openings because the ventilated facade principle means that wind pressure acting on the outer face of the panel is equalised in the cavity.
Therefore, there is no significant pressure differential to drive the rain through joints.During extreme weather, a minimal amount of water may penetrate the outer cladding. This, however, will run as droplets down the back of the panels and be dissipated through evaporation and drainage.
