Failures include air and water leakage, glass breakage, loss of (falling) metal components, fogging glass, and other serious deterioration. The authors will explain the reasons for the failures and explain how to avoid such problems.|We will also summarize a few recent successful curtain wall installation projects and some of the key design, preconstruction, and construction procedures that led to the successes and some critical tasks that are often overlooked.
