In addition to satisfying basic performance requirements, curtain walls installed in many health care and laboratory facilities are often required to meet more demanding performance requirements for durability, air and water penetration resistance, and thermal efficiency. To meet these demands, additional provisions that are above and beyond many curtain wall manufacturers' standard details are often necessary. The presenters will discuss glass-and-metal curtain wall technology, including an introduction to "standard" systems and enhancements recommended for hospital and laboratory facilities. Case studies and design examples from recent renovation and new construction projects will be highlighted. Results of in-situ moisture testing and monitoring will be used to bolster design recommendations.
