Two large glass industry companies are ending 2020 with major leadership announcements. Oldcastle BuildingEnvelope® (OBE), a global supplier of architectural glass, metal and hardware, has appointed Liz Haggerty as president. She succeeds Nathan Creech, who will move into a global leadership role within parent company CRH after three years in the role. In addition, Apogee Enterprises Inc.’s board of directors has named Ty R. Silberhorn as the company’s new chief executive officer (CEO) and a member of the board of directors, effective January 4, 2021.


Liz Haggerty

Haggerty will assume her new post effective January 1, 2021. She was named president of OBE’s architectural glass and metal division in January 2020.

“I’d like to congratulate Liz on her appointment,” says Creech. “As OBE enters our next phase of growth, Liz and her team are poised to continue to drive improvement and deliver results for our customers, employees and shareholders, as have been demonstrated by her leadership through the economic impacts of the COVID-19 pandemic.”

Haggerty is a trained metallurgical engineer with extensive experience leading the manufacturing of highly customized as well as standard building products. Her career spans 30 years in the HVAC industry where she has held numerous leadership positions in engineering, operational excellence, sales and distribution. Prior to OBE, she oversaw the unitary HVAC business segment for Johnson Controls. There, Haggerty led a global business, which included the responsibility for the design, manufacturing and sales of both commercial rooftop and residential ducted products.

“This is an exciting time in our company’s history. I am grateful for the opportunity to continue delivering for our customers and on our strategic vision to be the global leader of value-added, glazing focused products and services,” said Haggerty.


Ty R. Silberhorn

Silberhorn will join Apogee from 3M, where he is currently senior vice president of transformation, technologies and services. This appointment follows the company’s previous announcement of Joseph F. Puishys’ planned retirement. With Silberhorn’s appointment, Puishys is stepping down from his position as CEO and board member.

“It is my pleasure to welcome Ty as Apogee’s next CEO. He is a proven executive, who brings a passion for leadership, building high-performing teams and shaping businesses,” says Donald A. Nolan, Apogee’s board chair. “During his career at 3M, he built a track record of success, leading change, driving growth and strengthening the operational performance of several global business units. We are confident Ty is the right choice to take Apogee forward.”

Silberhorn will become the fifth CEO in Apogee’s 71-year history. He joins Apogee following over 20 years at 3M. In his most recent role with the company, he worked to reshape 3M’s efforts in business process and digital transformation to further enable growth and productivity. Prior to this position, he held several global business unit leadership roles, serving as vice president and general manager for divisions within three of 3M’s business groups, including safety and industrial, transportation and electronics, and consumer. Earlier in his career, he served in a variety of roles in sales, marketing and management, including Six Sigma business group director. His experience outside of 3M includes running his own startup e-commerce company and working at Ashland Inc.

“I am honored and excited to have the opportunity to lead this great company,” says Silberhorn. “Apogee is an established leader in its industry with a long history of growth and providing exceptional value for its customers. I am confident about the company’s future and look forward to working together with the board and the entire Apogee team to build on this legacy and lead Apogee into its next chapter.”
