Preventing moisture intrusion with rainscreens
Rainwater penetration is caused by the presence of water in the substrate, openings in the structural backup of the wall, and/or pressure differences (e.g. raindrop kinetic energy, surface tension, gravity, and capillary action) forcing water ingress through the structural backup.

rainwater intrusion into walls. They shed most of the rain and manage the rest to prevent moisture intrusion. Rather than attacking the symptoms of moisture intrusion, rainscreens tackle the source—the forces that drive water into a rcs data building shell. By neutralizing these forces, rainscreens can withstand extreme environments. They appear to be effective in any climate and handle any weather condition short of a disaster.

Rainscreens consist of the exterior surface of the building (cladding) that has direct contact with the weather and elements, but is not directly attached to the building substructure. It is a barrier that sheds and attempts to control, but does not prevent, the majority of the rainwater intrusion into the cavity between the rainscreen and the substructure. Rainscreens stand off from the moisture-resistant surface behind it, creating a cavity or pocket of air.
