Mativ Secures First Commercial Order for Advanced Materials in Miru’s Revolutionary eWindow Technology
In a groundbreaking development for the automotive and smart glass industries, Mativ (NYSE: MATV), a global leader in specialty materials, has announced its first commercial purchase order for advanced polymer film solutions used in Miru Smart Technologies’ (“Miru”) cutting-edge electrochromic window technology. This milestone underscores Mativ’s commitment to driving innovation, sustainability, and safety while supporting the large-scale adoption of dynamic smart glass systems by leading automotive OEMs.
Through its advanced polymer film brand, Argotec, Mativ is providing critical thermoplastic polyurethane (TPU) interlayer films that serve as a foundational component in Miru’s revolutionary eWindows. These windows dynamically adjust their tint on demand, delivering enhanced energy efficiency, improved passenger comfort, and an elevated user experience across both automotive and architectural applications.
A Strategic Partnership for Next-Generation Smart Glass
Miru, a pioneer in smart window innovation, collaborates with major global glass manufacturers and key supply chain partners to develop state-of-the-art dynamic electrochromic windows. At the heart of this technology lies Argotec’s specialty TPU interlayer film, which ensures exceptional optical clarity, durability, and manufacturability. The recent purchase order secures a significant volume of these advanced materials, reinforcing the readiness of the supply chain to meet growing market demands.
This collaboration has already yielded impressive results, including the successful fabrication of one of the world’s largest electrochromic sunroof prototypes—a compound-curved device measuring 1.5 meters by 1.6 meters. This achievement demonstrates the scalability of Miru’s eWindow technology and highlights its potential to revolutionize next-generation vehicle design.
Driving Innovation Through Collaboration
The partnership between Mativ and Miru represents a shared vision for customer-driven innovation platforms. After extensive co-development and rigorous materials testing, this first commercial order marks a pivotal step forward in scaling production capabilities.
“This order reflects our confidence in the market demand for Miru’s exciting eWindow technology and our shared commitment to innovation,” said Ryan Elwart, Group President of Mativ. “Argotec’s advanced films are engineered to meet the performance needs of smart glazing applications, and we’re proud to support Miru in scaling electrochromic glass for the future of mobility.”
For Miru, the collaboration ensures access to high-performance, scalable materials that align with the stringent optical and mechanical standards required for their eWindow systems. Curtis Berlinguette, Founder and CEO of Miru, emphasized the importance of this milestone: “Our partnership with Mativ strengthens our supply chain readiness and positions us to deliver reliable, high-quality solutions to customers worldwide. We’re excited to deepen this collaboration as we move toward full-scale production.”
Showcasing the Future at Glass Performance Days 2025
Industry professionals and innovators will have the opportunity to witness the transformative potential of Miru’s eWindow technology firsthand at Glass Performance Days (GPD) 2025, taking place in Tampere, Finland, from June 10 to 12. Visitors are invited to stop by booth F9 to explore live demonstrations of the eWindow system and learn about the joint solution developed by Miru and Argotec.
In addition to showcasing their technology, the companies will host a networking mixer during GPD, bringing together thought leaders and stakeholders to discuss the future of smart glass. This event aims to foster collaboration and inspire new ideas within the industry, further accelerating the adoption of advanced materials and technologies.
Why Electrochromic Windows Are Transforming Industries
Electrochromic windows, such as those enabled by Miru’s eWindow technology, represent a significant leap forward in sustainable building and transportation design. By dynamically adjusting tint levels based on environmental conditions or user preferences, these windows reduce reliance on HVAC systems, lower energy consumption, and enhance occupant comfort. In automotive applications, they also contribute to improved aesthetics and reduced glare, creating a more enjoyable driving experience.
As global demand for energy-efficient solutions continues to rise, the integration of advanced materials like Argotec’s TPU interlayer films becomes increasingly vital. These materials not only ensure the performance and longevity of smart glass systems but also enable cost-effective manufacturing processes at scale.
