Tremco Construction Products to Acquire Kalzip GmbH

The acquisition, valued at approximately €75 million ($81.8 million) based on Kalzip’s 2024 net sales, is expected to complete before the end of 2026.

By joining Tremco CPG, Kalzip will strengthen its international presence, the company says. The acquisition will benefit from Tremco’s broader network of complementary technologies “within a group that shares our commitment to innovation, sustainability and high performance building envelopes”, a Tremco spokesperson adds.

Kalzip has been manufacturing roofs and façades since 1968, delivering lightweight, visually distinctive aluminium building envelope solutions from its headquarters in Koblenz, Germany.

With more than 120 million m² of aluminium systems supplied worldwide, Kalzip has delivered many landmark projects.

Distinctive projects include the roofs of Barajas International Airport in Madrid, the Etihad Stadium in Manchester, Children’s Hospital Dublin and LAX Metro Station in Los Angeles.

“This acquisition represents a highly positive step for Kalzip, our customers and our employees,” said Andrew Leach, CEO of Kalzip GmbH.
