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 1,700 member companies include glazing contractors, full-service glass companies, glass and metal fabricators, primary glass manufacturers and glass building product suppliers.
What We Do
We bring together some of the best minds in the glass industry to develop standards, create technical resources, and promote and advocate for glass in the built environment.
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.
We bring news, product announcements, financial insights and more directly to your inbox or mailbox through our official publications Glass Magazine and Window + Door.
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.
