Open-joint cladding design elements are being applied by the world’s most advanced building professionals designing some of the most cutting-edge buildings. However, they require extra attention to manage the infiltration of exterior weather. While enhancing the visual aesthetics of a building, this design can expose structural components within the wall to wind, water, and sun, ultimately jeopardizing building performance if not properly protected.

Dr. Joe Lstiburek, acclaimed educator and founding principal of Building Science Corporation, discusses the challenges of open-joint cladding and best practices.
