Cold façade

Rear-ventilated constructions and multi-skin exterior wall constructions with rear ventilation are also referred to as cold façades in terms of building physics.

1. solid wall, load-bearing function
2. of insulating layer, protection against heat / cold,
3. rear ventilation, removal of building and usage moisture
4. , curtain wall cladding, protection against weather / architectural appearance

Rear ventilation thermally decouples the outer layer (weather protection) from the primary structure (supporting structure), while the outer layer remains "cold". The heat-insulating function is usually taken over by the insulation level, e.g. in the case of highly thermally insulating perforated bricks, only by the construction layer.
