RPM International Inc. announced that a definitive agreement has been signed for its Tremco Construction Products Group to acquire Kalzip GmbH, a global leader in the design and production of metal-based roofs and facades for building envelopes. The transaction will bolster Tremco CPG’s building envelope systems capabilities with a premier brand known for architectural innovation and high-performance solutions that meet demanding specifications.

Kalzip is a globally recognized leader in aluminum roofing and façade systems. Headquartered in Koblenz, Germany, the company specializes in customized lightweight, weather-resistant building envelope technologies. Delivering over 1.2 billion square feet of aluminum solutions worldwide, key projects have included El Prat Airport roof refurbishment in Barcelona, Mercedes Benz Arena in Berlin, Children’s Hospital Dublin and Ikea Dubai. Kalzip generated calendar year 2024 net sales of approximately €75 million. The acquisition enhances Tremco CPG’s position in key international markets, including Europe and India, while creating future opportunities to expand Kalzip’s aluminum systems to North American customers.

The addition of Kalzip represents a strategic enhancement to Tremco CPG’s integrated portfolio of building envelope solutions, which includes roofing restoration and maintenance systems, field-applied and panelized EIFS, panel systems, sealants, waterproofing and more. This combination aligns with Tremco CPG’s strategy to offer a seamless, end-to-end approach to construction that enhances building efficiency, durability and aesthetics.

The transaction is expected to close in the fourth quarter of fiscal 2026, subject to customary closing conditions. Andrew Leach, along with the current senior management team, are expected to remain with the business to ensure continuity and accelerate growth in partnership with Tremco CPG.

“This acquisition aligns with our strategy to build leadership positions in selling systems to high-growth, high-specification construction markets,” stated Frank C. Sullivan, RPM chairman and CEO. “Kalzip provides Tremco CPG with a world-class platform in the attractive aluminum building envelope sector that enhances building efficiency and durability. We are well-positioned to leverage our global marketing and operational expertise to support the brand’s continued growth. I am pleased to welcome the talented Kalzip team to RPM.”
