Rainscreen Systems Provide Superior Moisture Protection
Numerous terms have been used in the past to describe rainscreen systems, which has caused some confusion as to what a rainscreen really is.
One of the most successful technologies used today to deter rainwater intrusion into a building's exterior wall and protect its envelope is the rainscreen system. Introduced more than 20 years ago in the United States, rainscreen technology has continued to advance, along with its popularity among building owners who desire a "stylish raincoat" for their structure.
Walls with rainscreen systems tend to be more durable and are less prone to costly repairs resulting from water damage. In addition to water infiltration, rainscreen systems are also effective at managing air infiltration, negative wind pressures, heat transfer and vapor transmission into and out of a building. The only real drawback to a rainscreen system is the added cost associated with its more complex design and installation, according to Michael Radigan, Western Specialty Contractors Building Facade - Rainscreen Division.
