Founded in 1948, the National Glass Association is the largest and most influential trade association serving the architectural glass, and window and door industries. The NGA represents nearly 2,200 member companies, produces the industry's leading events and publications, and provides cutting-edge education and training programs. Its sister organization, the Window and Door Dealers Alliance, represents the interests of retail, wholesale, and installing dealers of new and replacement windows, doors, skylights, and related building products. The NGA's annual events— including GlassBuild America and the Glazing Executives Forum—serve as a centralized meeting place for thousands of professionals.
