It was the first industry event from the now-combined National Glass Association and Glass Association of North America. Below: During GlassBuild America 2017, some members of the combined NGA board of directors, along with Nicole Harris, president and CEO of the NGA, announced the boards' unanimous decision to move forward with a member vote to combine.

NGA Board of Directors

The new board of directors of the combined associations will consist of 13 voting members:

  • 3 glazing contractors
  • 3 full-service glass companies
  • 2 Window and Door Dealers Alliance dealers
  • 2 glass fabricators
  • 1 primary glass manufacturer (company changes yearly or biennially)
  • 2 glass industry suppliers
  • the NGA President/CEO as a non-voting ex officio member

On Feb. 1, 2018, the National Glass Association and the Glass Association of North America merged to form the largest trade association serving the architectural glass and glazing supply chain, including glazing contractors, full-service glass companies, glass fabricators, primary glass manufacturers and suppliers to the industry. 

Trade associations reflect the industries they serve, and with ongoing consolidation among architectural glass and metal companies, combining two legacy member organizations was due for consideration.

“The boards, memberships and the professional staff of both organizations have taken a huge step forward for the industry,” says Rod Van Buskirk, president, Bacon & Van Buskirk. “History teaches us the industry has constantly changed and evolved over decades, and so, too, have our trade associations. I look forward to how the newly combined association will grow and evolve yet again to better serve all of our various industry segments.”

Combining NGA and GANA is a continuation of glass industry segment mergers that occurred over several decades, especially within GANA’s history. “What this combination finally achieves is the unification of the entire supply chain,” says Nicole Harris, president and CEO of the NGA.

It also allows two proud membership organizations to pool resources, volunteers and staff to better meet the needs of the industry they serve. 

“GANA and NGA have supported each other in the past, but now, as a single organization, I am looking forward to the synergies among all segments of the glass industry,” says Valerie Block, architectural marketing consultant, Kuraray America Inc.

Combined strengths

Members can expect more technical information, education, training, and other tools and resources to help them improve their businesses. There is also cost-savings for members and the association as a whole. 

“You want to belong to as many organizations as you can, but it’s hard, because each has dues,” says Dustin Anderson, Anderson Glass & Mirror. “NGA and GANA are two powerhouses, and the beauty is, I don't have to make that decision anymore. They're coming together, sharing information. It's quality, and on the same page.” 

“By removing duplicative efforts, and redundant costs, members can expect a more efficient and beneficial industry experience,” agrees Chris Mammen, CEO, M3 Glass Technologies

It wasn’t lost on the leadership of either organization that NGA and GANA had similar mission statements focused on three principles: provide, promote and protect. The two organizations also shared strong legacies of committed volunteer participation. 

“Both organizations have a well-established history of contributing to and promoting the glazing industry. Change is always difficult, but just think of what may be possible going forward with an expanded membership and additional resources to amplify the ‘Voice of the Industry,’” says Steve Marino, manager, technical services, Vitro, who served on the GANA board and on the NGA-GANA Joint Task Force.

“This integration is a natural progression. It’s no different than years back with GANA’s consolidation. It’s a positive for the industry to combine strengths of two organizations into a larger organization and makes financial sense for the associations,” says Arthur Berkowitz, board member for Consolidated Glass Holdings.

How best to structure the new combined association to be a powerful, purposeful voice for the industry is beingscoped out now by the Integration Task Force. Made up of six representatives, three each from NGA and GANA, the ITF’s top priority is to ensure that the important GANA technical and advocacy work continues uninterrupted. 

“Everyone involved in working on the combination and working to smooth out the wrinkles on the task force has the best interests of our industry in mind, and are seasoned veterans of the industry and [the associations],” says Gus Trupiano, director of sales, Building Products, AGC Glass North America

At the Annual Conference, in Napa, California, April 26-28, the ITF will present to committee leadership and members. The new technical structure for the combined association will be announced at the Fall Conference preceding GlassBuild America, Sept. 12-14, in Las Vegas. 

“Technical advocacy has to be strengthened with this combination. The NGA has a stronger glazier orientation, versus GANA with its focus on manufacturers who drive development and output. I am hopeful that NGA will marry the strengths of both.” Chuck Knickerbocker, curtain wall manager, Technical Glass Products

Strengthening a legacy

In addition to combining the strengths of volunteers and staff, the new association combines resources to inform and promote the industry.

“We rely on the associations to be a voice for the industry on key advocacy issues and educate on technical matters,” says Helen Sanders, strategic business development, Technoform. “As these issues evolve over time, we need resilient structures to address changes in the market and built environment. By combining GANA and NGA, we will bring even more industry stakeholder voices together to create a unified and more influential advocacy platform.”

GANA had a long history of generating important technical documents and code advocacy. NGA provides educational platforms and resources, North America’s largest trade show and an industry-specific magazine. Now, a much larger organization with additional resources can expand the work—produced by volunteers and executed by staff—that both organizations bring to the glazing industry.

“I hope the new combined association can be a strong voice of advocacy on issues that are important to the glass industry and the association membership,” says Chris Dolan, director, commercial segment for Guardian Glass. “Glass sometimes is maligned … I hope the new organization can provide focus to become an advocate for glass use and all its possibilities.”

“When we don't work together and introduce products that don't work in the field, the industry gets a black eye,” agrees Berkowitz. “When you combine the expertise of glazier with a glass fabricator, it’s a positive to the industry and ensures our success and future.”

“At the end of the day, we need to promote glass. We now have a unified voice with a strong technical base [and] the critical mass of a [fully integrated] membership. We have an opportunity to grow the entire organization for everyone to be more successful.” Ren Bartoe, director of glass and industrial technologies for Vesuvius, and Integration Task Force member
