NGA combined with the Glass Association of North America (GANA) in 2018 to create the largest trade association serving our industry. Our 1,500 member companies include glazing contractors, full-service glass companies, glass and metal fabricators, primary glass manufacturers and glass building product suppliers. NGA’s sister organization, the Window and Door Dealers Alliance (WDDA) serves retail, wholesale, and installing dealers of new and replacement residential windows and doors. • NGA is a technical powerhouse that brings some of the best minds to the table to create technical resources, and to promote and advocate for glass in buildings. • Our information bulletins and business resources help guide you and your company to success, and our online training courses at, teach basic job skills and knowledge that will complement your company’s on-the-job training. • We bring news, product announcements, financial insights and more directly to your inbox or mailbox through our official magazines Glass Magazine and Window + Door. • And our many events throughout the year—GlassBuild America, Annual Conference, Building Envelope Contractors (BEC) Conference, Fall Conference, Glazing Executives Forum, GPAD (Glass Processing Automation Days), and Window & Door Dealer Day—provide a gathering place for you to learn, share, engage, and make connections to help you and your business grow.
