Who We Are
NGA was founded in 1948. In 2018, we combined with the Glass Association of North America (GANA) 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, focuses on the interests of retail, wholesale, and installing dealers of new and replacement residential windows, doors, skylights, and related building products.
What We Do
Our informational bulletins and business resources help guide you and your company to success, and our online training courses at MyGlassClass.com, teach basic job skills and knowledge that will complement your company’s on-the-job training.
And our many events, like GlassBuild America, Annual Conference, Building Envelope Contractors (BEC) Conference and others, provide a gathering place for you to learn, share, engage, and make connections to help you and your business grow.
