SOBOTEC’S WALL PANEL SYSTEM PASSES THE PRESSURE-EQUALIZED
RAINSCREEN SYSTEM TEST (AAMA 508-07)
With outstanding results, Sobotec’s SL-2000 wall panel system design has passed
the “Volunteer Test Method and Specification for Pressure-Equalized Rain Screen Wall
Cladding Systems.”
The AAMA 508-07 test takes rainscreen performance testing to the next level. It
requires the panel system to employ the advanced ‘Pressure-Equalized and
Compartmented’ (PE/C) rainscreen concept. This not only requires the proper
management of penetrating water but also the prevention of water penetration. The
compartmentalized system design concept is based on stringent pressure equalization
requirements by the American Architectural Manufacturers Association (AAMA).
The research and development team at Sobotec has been able to improve the
SL-2000 panel system response time to varying static and dynamic pressures created by
wind and driving rain. As a result, the air flow—which inherently carries water or
moisture—is virtually eliminated while any water that does enter the system is able to
quickly drain or dry out.
