Mutares signs an agreement to acquire Kawneer EU from Arconic

The transaction strengthens the Mutares Engineering & Technology segment as a new platform acquisition and is expected to close in the fourth quarter of 2025, subject to merger control approval.

Kawneer EU is a leading designer, manufacturer, supplier, and distributor of aluminum window and façade systems, operating through three country-focused business units in the Netherlands, France, and the UK, each with deep market penetration and long-standing customer relationships. With over 450 customers and four highly efficient facilities, the platform delivers comprehensive building envelope solutions, including windows, doors, sliders, curtain walls, and framing systems in residential and non-residential markets, making it a one-stop shop for customers. The company generates approximately EUR 125 million in revenues and employs over 400 people.

Kawneer EU provides value through its products and service offerings across the entire value chain. The company’s brand is well-known for its reputation in quality, performance, energy efficiency, and ease of installation, which has earned it a loyal customer base.

Recent investments and market confidence have positioned Kawneer EU for growth and improved profitability. Mutares continues to support Kawneer EU’s transformation into a standalone European specialist through operational improvements, geographic expansion in Europe, and product innovation. The platform’s consolidated structure enables cost efficiencies and shared services across IT, procurement, and finance, enhancing profitability and scalability.

Johannes Laumann, CIO of Mutares, comments: “This acquisition marks a strategic step in further strengthening our construction focus in the Mutares Engineering & Technology segment. Kawneer is a perfect strategic fit for our existing portfolio companies, Byldis and Smart Curtain Wall – which is a part of Kalzip. These companies together broaden Mutares´ technological capabilities and customer offering, creating a competitive player in the European window and glass façade market. I am confident that, through further operational improvement initiatives, we can successfully increase profitability and market share while establishing a robust foundation for sustained growth.”
