Expands Its Aluminum Roof and Façade Systems Portfolio
BEACHWOOD, OH / ACCESS Newswire / April 1, 2026 / Tremco Construction Products Group ("Tremco CPG") today announced the successful acquisition of Kalzip GmbH ("Kalzip"), following completion of the standard regulatory review process. A global leader in the design and production of aluminum-based roofs and facades for building envelopes, Kalzip now is part of Tremco CPG.
Based in Koblenz, Germany and founded in 1986, Kalzip specializes in lightweight, weather-resistant and flexible roof systems, as well as aesthetically advanced and functional facade technologies. Their cutting-edge roll-forming machines and mobile production units ensure high-quality, customizable solutions for architects, planners and installers. Delivering over 1.2 billion square feet of aluminum solutions worldwide, key projects have included LAX Metro Station in Los Angelos; the Louisiana Superdome; Santiago Bernabéu football stadium in Madrid, Spain; Children's Hospital Dublin, Ireland; and the Pickering GO Pedestrian Bridge in Ontario, Canada - the world's longest enclosed pedestrian bridge.
"In addition to expanding our business across Europe, India and other regions around the world where Kalzip already has a strong presence, this acquisition will eventually allow Tremco CPG to market a wider range of aluminum building envelope options to our North American customer base," said Scottie Stinson, president, Tremco CPG Inc. "This is critical as demand grows for aluminum building systems due to their many benefits including durability, longevity, sustainability and energy efficiency."
Strategic Alignment with Focus on High-Performance Building Envelopes
Combining Kalzip's innovative aluminum technologies with Tremco CPG's integrated portfolio-which includes a range of roofing restoration and maintenance systems, field-applied and panelized EIFS, MCM and ACM panels, sealants and waterproofing, floor coatings, passive fire protections and structural solutions-aligns with Tremco CPG's strategy of offering a seamless, integrated approach to modern construction, enhancing efficiency, durability and aesthetic appeal for new construction and restoration.
"Our global reach, complementary product portfolios and customizable solutions will enable Kalzip, as part of Tremco CPG, to deliver tailored, high-performance, end-to-end building envelope systems for varied architectural and restoration needs across diverse markets and large-scale projects," Stinson said. "And our shared commitment to green building practices will continue to drive innovation in sustainable construction worldwide."
Looking Ahead in North America
In North America, Kalzip's aluminum roofing and façade products will eventually be integrated into the Tremco CPG brands. This transition will provide customers with expanded options within Tremco's trusted product lines. More details will be shared as the rebranding process progresses.
Outside of North America, Kalzip's products will continue to be marketed under the Kalzip brand, maintaining the company's strong presence and reputation in Europe, India and other global markets.
