What is a rainscreen system? A rainscreen system can be considered as an exterior wall assembly that aims to shield buildings from rainwater, wind action, and other weather-related damages. The mechanism behind the operation of the rainscreen system is based on the creation of a ventilated gap between the outer cladding and the wall itself. This space ensures proper drainage of water and provides ventilation for drying the remaining moisture, thus protecting the wall structure from any mold or rot growth.

An outer layer of the rainscreen system serves as a first protection from external rain and severe weather conditions. The layer beneath it is referred to as the weather-resistant barrier that provides additional protection for the building.



One of the advantages of rainscreen systems is their ability to provide increased durability of a building since they ensure energy savings, reduced maintenance needs, and longevity of exterior walls. Moreover, such systems can be installed using different materials including metal panels, fiber-cement boards, wood, and composites.
