This course provides AEC professionals with both an overview of the problems that can lead to failure in glazed curtain wall systems, and the means by which to remediate these failings. The course presents a brief history of the development of glazed curtain walls, then moves quickly into the causes of distress and failure and considerations for rehabilitation and remediation. Also provided: a glossary of basic terms in curtain wall construction and a short review of infrared testing of glass curtain wall systems.
Based on the information presented in this AIA/CES Discovery course, you should be able to:
- Identify causes of distress in glazed curtain wall systems that can lead to premature failure, necessitating the consumption of additional materials, energy, and manpower resources for remediation.
- Describe types of glazing and frame construction commonly used in curtain wall systems, and explain the benefits and drawbacks of each in terms of energy, safety, performance, cost, environmental impact, and construction scheduling.
- Apply ASTM International test standards to the evaluation of existing curtain wall systems, so as to assess air and water penetration resistance and structural integrity and thereby protect the health, safety, and welfare of occupants and users.
- Adapt design considerations, including energy efficiency, fire safety, seismic and wind loading capacity, and daylighting, to the rehabilitation of glazed curtain walls, in order to improve building performance (including indoor environmental quality) and extend the service life of the building (i.e., durability).
