Rainscreens provide a successful method for deterring rainwater intrusion into walls. Rain screens shed most of the rain and manage the rest, preventing moisture intrusion and premature decay in homes.

Tackling the source

Rather than attacking the symptoms of moisture intrusion, rain screens tackle the source - the forces which drive water into the building shell. By neutralising these forces, rain screens can withstand extreme environments. They are effective in any climate and handle any weather condition.

All rain screens include the following elements:

There are four basic approaches to water penetration control in buildings:

Mass: traditional, solid assemblies that shed most surface water, effectively absorb the remainder, and subsequently release absorbed moisture as a vapor. Examples include solid concrete, masonry, and timber structures. This approach has variable effectiveness in most climates.

Barrier: surface designed to completely shed surface water with no moisture penetration.

Internal drainage plane: a drainage plane or moisture barrier located between the exterior cladding and the supporting wall that provides redundancy of moisture resistance.

Rain screen: a moisture-management system incorporating cladding, air cavity, drainage plane, and airtight support wall to offer multiple moisture-shedding pathways.
