Concrete panels inner layer (103)

In this evolution of the rain screen façade towards prefabrication, seeking to build both, the interior and the exterior layers, with dry systems highly prefabricated, it is not that usual to find massive solutions. Those solutions would permit, not to lose thermal inertia, or decrease the acoustic barrier.

The inner sheet based on heavy concrete panels is a very good option.

The clue in these situations is understanding the role of the outer sheet and the camera. The panel system is watertight and airtight since the joint is sealed. The cavity and the outer layer of these rain screen facades serves to block the effect of direct sun radiation, taking advantage of the ventilated cavity to dissipate the excess of thermal energy.

It is a ventilated facade, not a rain screen. The outer layer, plus the cavity, do not behave as a rain screen but as a sun shading.

Obviously water tightness has been improved thanks to the outer layer, the cavity, and the fact that the sealing of the joints between panels are now protected from the effects of direct sun radiation.
