This course examines the use of opaque glass as a façade material in a drained and back ventilated rainscreen system. Highlighted within will be the design consideration and benefits thereof when designing with and specifying opaque glass rainscreen. The importance of the building science principle of exterior wall assembly control layers, and the role they play in providing occupant health and safety will be emphasized for use with opaque glass, open-joint, drained and back ventilated complete rainscreen systems. This presentation will also address sustainability, safety and durability benefits that are associated with properly designed and manufactured opaque glass panels. We will provide an understanding of required test criteria and typical test results when opaque glass panels are used within an open-joint, drained and back ventilated complete rainscreen system.
