Testing Rainscreens to AAMA 508 & AAMA 509 - Recorded Webinar


The rain screen design principle relies on the cladding panel to resist wind loads, protect the wall system from UV exposure, limit water intrusion into the wall system and allow trapped moisture to escape to the exterior of the wall system. The purpose of this free 60-minute recorded webinar is to educate manufacturers, architects/ specifiers, as well AHJ’s and the building inspection community, about the differences between rainscreen systems, and how they are tested within a laboratory environment




  • Understand the differences between the two standards
  • Provide main attributes of testing to AAMA 508 and AAMA 509
  • Discuss the test specimen setup and pass/fail criteria as required by the standards
  • Provide examples regarding lab testing
