Our experience with drained and back-ventilated rainscreen assemblies in North America is extensive. In fact, Cladding Corp was an original industry member of the AAMA Task Force responsible for developing the AAMA 509 Standard – the first North American testing standard for Drained and Back-Ventilated (DBV) Rainscreen Cladding.
This ground-breaking new standard was developed to create a benchmark in DBV rainscreen performance and provides specific criteria for ventilation and moisture control. As expected, joint design in a DBV rainscreen has a dramatic impact with the amount of water penetration within the rainscreen assembly. This is why Principle #2 – Outer Moisture Control – is so critical with DBV rainscreens.
All Cladding Corp systems follow The 5 Principles of Rainscreen Cladding Design and subscribe to the requirements of AAMA 509. In fact, Cladding Corp has the first system test report provided by AAMA for the 509 Standard. If you are interested in more information on the new standards, please contact us.
