The rainscreen cladding system is an advanced facade that provides the necessary protection against water penetration into buildings and improves their performance parameters. In particular, it can be described as a two-layer facade construction consisting of the outer "cladding" wall and the inner structure of the building, which is isolated from each other through an air gap.
Thus, what are rainscreen cladding systems utilized for? First, it needs to be highlighted that rainscreens ensure that buildings get protection from adverse weather conditions, including rainwater and, at the same time, prevent moisture accumulation. Contrary to traditional facade constructions that rely on one waterproof layer, rainscreens operate according to the pressure equalization and drainage principle. The main advantage of rainscreens is that moisture that may enter the building from the outside evaporates.
As far as the materials used to produce the outer wall are concerned, there is a range of options, such as aluminum panels, fiber cement boards, terracotta tiles, high-pressure laminate (HPL), composite materials, etc.
The importance of the cavity behind the cladding lies herein. The ventilation provides continuous air flow within the wall structure, ensuring the optimal condition of temperatures and humidity. This way, the system increases energy-efficiency, improving overall thermal performance of the building.
Another advantage of the rainscreen system lies in the increased lifespan of the structure itself. Thanks to the reduced moisture exposure, the cladding helps reduce costs associated with the structure’s maintenance and ensures that the building envelope remains healthy for a longer period of time. Rainscreen cladding systems can be applied in commercial facilities, apartments, and even institutions around the world.
To conclude, the rainscreen cladding system is more than just a facade – it is one of the most effective technologies used in contemporary construction.
