The most important thing to consider when deviating from the traditional rainscreen types is the system’s behavior; each part of the building envelope must be carefully studied prior to specification. Once the envelope materials are selected, they should be examined again as a system, for moisture loading on the wall, and drying forces in the cavity. If care is taken in the design stage with use of proper materials, a number of combinations are available to create a rainscreen that will offer
a lasting line of defense against water penetration into structures.
Standards
Association (AAMA) 508-7, Voluntary Test Method and Specification for whatsapp number database Pressure-equalized Rainscreen Wall Cladding Systems, and AAMA 509-9, Voluntary Test and Classification Method of Drained and Back Ventilated Rainscreen Wall Cladding Systems, can be used to determine the performance of a variety of products used in rainscreen applications.
In AAMA 508-7, the rainscreen must prevent water penetration throughout, vent water vapor, have a WRB that resists the full positive and negative wind load, not trap or conceal water, and be able to control water penetration.
