Welcome to the Glass Documents Website

The Glass Documents Website is jointly sponsored by the American Architectural Manufacturers Association (AAMA), the Glass Association of North America (GANA), the Insulating Glass Manufacturers Alliance (IGMA) and the National Glass Association (NGA). All sponsoring organizations are active in standards development and publication of manuals, technical bulletins, test methods and reports in North America. These documents encompass all areas of glass for fenestration and are categorized within the site by Codes & Standards, Design & Fabrication, Voluntary Test Methods, Post Fabrication & Installation, Thermal Performance and Care & Maintenance. AAMA, GANA, IGMA and NGA have teamed up to provide this one-stop reference site listing all publications and documents relating to fenestration glass for the benefit of the architectural and code communities in North America irrespective of jurisdiction. This website will provide you with the sources of information you need to ensure code compliance and good design. The four organizations will be continuously updating the site with document references as they become available. Our goal is for this site to be relevant, timely and of service to the industry. We appreciate your feedback.

Since 1936, the American Architectural Manufacturers Association (AAMA) has stood as a strong advocate for manufacturers and professionals in the fenestration industry with respect to product certification, standards development, education and training, legislative regulations and building and energy codes. AAMA is a material-neutral organization comprised of window, door, skylight, curtain wall and storefront manufacturers and their suppliers and test labs.
