hinterlüftungssystem

Hinterlüftungssystem is a German term that translates to "ventilated facade" or "rear-ventilated facade" in English. It refers to a building construction method where an air gap is created between the outer cladding and the building's primary wall structure. This air gap is intentionally designed to allow for airflow, facilitating natural ventilation.

The primary purpose of a hinterlüftungssystem is to improve the thermal performance and moisture management of a building. The circulating air within the gap helps to remove moisture that may build up on the inner surface of the cladding or the outer surface of the primary wall. This prevents condensation and the potential for mold growth, which can damage the building's structure and negatively impact indoor air quality.

In warmer months, the airflow can also help to dissipate heat that builds up on the exterior cladding, reducing the amount of heat transferred into the building and thus lowering cooling loads. In colder months, the trapped air can act as an insulating layer, further improving the building's thermal efficiency.

The outer cladding of a hinterlüftungssystem can be made from a variety of materials, including stone, wood, metal, or composite panels. These materials are typically attached to a substructure that is fixed to the primary wall, creating the necessary air gap. The design of the hinterlüftungssystem, including the width of the air gap and the placement of ventilation openings, is crucial for its effectiveness. It is a widely used and effective method for enhancing building performance and durability.
