Regenrückseitenlagen

Regenrückseitenlagen, often translated as "rain screen cladding" or "rainscreen systems," are a building construction technique designed to protect the exterior walls of a building from moisture damage. The core principle involves creating a gap or cavity between the outer cladding material and the underlying weather-resistive barrier. This cavity allows for ventilation and drainage, effectively managing any water that penetrates the outer layer.

The outer layer, known as the rainscreen, can be made of various materials such as wood, metal, stone, or fiber cement. Behind this layer, a weather-resistive barrier, typically a house wrap or building paper, is applied to the sheathing. The space between the rainscreen and the barrier is crucial. It allows air to circulate, drying out any moisture that may enter, and provides a path for water to drain down and out of the wall assembly.

The benefits of using Regenrückseitenlagen include improved durability of the building envelope, reduced risk of mold and rot, and increased energy efficiency due to better drying capabilities. By preventing water from accumulating within the wall structure, these systems significantly extend the lifespan of the building and contribute to a healthier indoor environment. Installation requires careful attention to detail to ensure proper sealing and detailing at all openings and penetrations.
