GANA Spring Supplement
An Introduction to GANA 

Founded in 1994, the Glass Association of North America (GANA) is the convergence of three glass and glazing industry decades-old associations: the Flat Glass Marketing Association (FGMA), Glass Tempering Association (GTA) and the Laminators Safety Glass Association (LSGA). The original structure of GANA consisted of three divisions, with each division having equal representation on the association’s board of directors. Today GANA includes seven divisions: building envelope contractors (BEC), decorative, flat glass manufacturing, insulating, laminating, mirror and tempering.

Meeting Member Needs
GANA has a large arsenal of tools to address the different needs of each division. One of the most visible tools is its group of targeted and highly successful meetings, conferences and seminars. Meetings are an important resource for GANA members, and provide significant opportunities for attendees to pool and share technical resources and information, ideas and experiences with peers, customers and suppliers. GANA conducts several industry meetings and educational seminars each year for specific segments of the industry.

Industry executive management and technical leaders gather in the first quarter of the year for Glass Week™, an annual event that passed its 21st anniversary this year. Glass Week features committee meetings to target and solve issues facing the industry, as well as the development of standards, test methods and other technical documents designed to help better the glass and glazing industry. Industry-related forums and executive-level informational presentations and roundtables, as well as networking and social opportunities enhance the opportunities available to attendees. 

The BEC division hosts the annual BEC Conference™, the industry’s leading opportunity for glazing contractors, window and curtainwall erectors and their suppliers to gather and address industry issues. Growing from only a handful of attendees at its first meeting to more than 500 in 2007, the BEC Conference has become one of the top events for the entire glass and glazing industry. 

Later in the spring, GANA hosts the annual Glass Fabrication Educational Seminar™, which focuses on in-depth training for fabricators, and features sessions on glass insulating, laminating and tempering fabrication procedures. GANA also hosts the Contract Glazing Educational Conference™ with technical presentations and forum discussions for project managers, sales and estimators. The annual GANA Fall Conference concludes the year by providing more intense committee work, industry presentations and networking. This event is held in conjunction with GlassBuild America, which is co-sponsored by GANA.

Technical Information
While each division includes several committees that address subjects of specific concern to its members, the individual technical committees are responsible for the association’s major publications. GANA publishes a number of technical manuals and free downloadable informational bulletins, with the Glazing Manual, Sealant Manual, Engineering Standards Manual and the Laminated Glazing Reference Manual as the most referenced and extensively used by the industry, government, architects and specification writers. The technical committees make a concerted effort to see that association technical manuals and information address the current needs of the industry.

In addition to its technical committee work, GANA members and staff actively represent the industry in the development of industry codes and standards, and also serve as liaisons to other fenestration-related organizations including the American Architectural Manufacturers Association (AAMA), Glazing Industry Code Committee (GICC), Insulating Glass Manufacturers Alliance (IGMA), National Glass Association (NGA) and Protective Glazing Council (PGC). GANA’s general counsel monitors the activities of Congress and those federal regulatory agencies that impact the association’s members or the industry. The general counsel also regularly attends association meetings and monitors its activities and publications to ensure strict compliance with current laws and regulations, particularly anti-trust regulations.

Communication is Key
Timely communication is essential in today’s business environment, and the association’s website (www.glasswebsite.com), newsletter (Glass Reflections), Special Bulletins (issued on an as-needed basis) and monthly Safety Bulletins all serve to keep members and the entire industry informed regarding technical, people and environmental issues that are a part of the day-to-day operations of a glass and glazing business. In addition, USGlass magazine has served as GANA’s official publication since September 2003. USGlass has the largest circulation of any glass trade magazine and provides the industry with news articles and features on topics that matter in an unbiased manner.

GANA is committed to helping members develop the management and technical skills needed to remain competitive in a continually changing business environment, while maintaining the flexibility to respond promptly to matters of importance to members and the industry.

Architects Design with Wood – Within the Glass 
OKAWOOD insulating glass from SCHOTT North America in Elmsford, N.Y., is composed of two lites of glass with a wood grid placed between them. This grid provides solar protection, yet still enables warm daylight to enter through the glass. The type and width of the wood, as well as the intervals within the grid, can be customized.  www.us.schott.com 

Tamglass Upgrades Sonic™; Bavelloni Introduces New Cutting Lines
Two Glaston Technologies companies, Tamglass and Bavelloni, have upgraded equipment lines.

Tamglass upgraded its high-speed Sonic™ full convection tempering furnace to provide “Easier than ever™” tempering of super low-E glass.

The latest Sonic was designed to reduce processing time, maximize quality and minimize breakage rates. 

Bavelloni has introduced new LAMY cutting tables for laminated glass. The new tables feature a break-out technology that uses a triple wheel, eliminating micro-splinters; side grippers that only touch the edge of the glass, so rollers or suction cups are no longer needed. The company says this innovation enables the line to offer numerous advantages, including the ability to process low-E glass with limited contact to the glass surface. www.tamglass.com  www.bavelloni.com
