AAMA releases voluntary test and classification method for drained and back ventilated rain screen wall cladding systems

AAMA 509-09, a test and classification method based on the results of testing a representative sampling of drained and back ventilated rain screen wall cladding systems has been released by the American Architectural Manufacturers Association (AAMA).

The document is titled Voluntary Test and Classification Method for Drained and Back Ventilated Rain Screen Wall Cladding Systems and addresses air leakage of the air/water barrier, air flow/cavity ventilation and water management. The primary purpose of this test method is to quantify the volume of rain water contacting an imperfect air/water barrier and the system’s ability to allow for ventilation/drying as measured by air flow through the cladding.
