The names Giesse, Schlegel, Reguitti, Era and Zoo are well-established in the global fenestration industry, representing decades of excellence in the design, manufacture, and distribution of high-quality hardware, sealing systems, and decorative solutions for windows and doors. These brands have long been synonymous with quality, innovation, and customer focus, building a strong presence across global markets. Now, they embark on a new journey under the ownership of Quanex, signalling both a continuation of their legacy and the start of an exciting new era of integration and growth.
Quanex Building Products Corporation, a global leader in high-performance fenestration components and other building solutions, acquired all legacy Tyman brands as part of a broader strategy to strengthen its position in the industry. Headquartered in Houston, Texas, and founded in 1927, Quanex operates across more than 60 sites globally and employs over 7,000 people. The company serves Original Equipment Manufacturers (OEMs) in over 90 markets worldwide, offering a diverse portfolio that includes window components, PVC extrusions, wood panelling, specialised access systems, and even solar panels.

With this strategic acquisition, Quanex has expanded its global footprint and brand portfolio significantly, pushing its annual turnover to nearly $2 billion. By bringing together the strength of these iconic brands with its own established operations, Quanex is now even better positioned to lead through innovation, geographic reach, and customer-focused service.
Central to this strategy is the investment in Centres of Excellence, which will drive future product development in both seals and hardware. From fully recyclable thermoplastic vulcanised (TPV) sealing systems to smart, concealed automation hardware, the emphasis is firmly on pushing the boundaries of what’s possible in fenestration. These technological advancements are designed not only to meet current market demands but to anticipate and lead them, with a firm commitment to reducing environmental impact and enhancing product performance.

For customers, the integration with Quanex means more than just continuity. It represents a strengthened partnership backed by expanded capabilities, a broader product range, and the financial and operational power of a global leader. While the Giesse, Schlegel, Reguitti, Era and Zoo brands will continue to deliver the trusted solutions they are known for, they will now do so with access to Quanex’s extensive R&D, manufacturing, and service infrastructure.
This transition marks the beginning of a bold new chapter. As part of Quanex, Giesse, Schlegel, Reguitti, Era, and Zoo are now part of something bigger®, and they are set to play an even more influential role in shaping the future of the fenestration industry.
