Custom curtain wall assemblies provide an excellent way to create a true architectural signature on a building. These systems are most often used to make a key statement at the entrance or podium level, and to convey the design language of the building. The ‘investment’ made in them is as much about the firm’s design reputation, as it is about actual project budget.

Testing Glazing in the Field: Performance Classes

Up until the 2008 edition of American Architectural Manufacturers Association/Window and Door Manufacturers Association/Canadian Standards Association (AAMA/WDMA/CSA) 101/I.S.2/A440, North American Fenestration Standard/Specification for Windows, Doors, and Skylights (NAFS), there were five performances classes of windows with differing requirements for test pressures, allowed leakage rates, and other variables. This sidebar discusses the current four types, and their minimum performance grades.
