New High-Performance Window and Door Systems Successfully Tested for the European Market

REGWEN is pleased to announce that our newly developed RG70 Casement Window, RG95 Casement Window, and RG80 Casement Door have successfully completed performance testing at a laboratory designated by TÜV Rheinland Netherlands.

The test results demonstrate that all three systems achieved excellent performance and fully comply with relevant European standards. The test reports have now been officially reviewed and approved by TÜV Rheinland Netherlands, marking an important milestone in our product development for the European market.

At REGWEN, product performance is not just a requirement — it is a core principle throughout our entire development and production process. From system design and profile engineering to sealing structures, hardware integration, and glass configuration, every detail is carefully optimized to ensure reliable performance.

To further support this, our factory is equipped with in-house testing facilities for key performance indicators such as air tightness, water tightness, and wind load resistance. Each product undergoes strict internal inspection before delivery, helping to ensure consistent quality and compliance with project requirements.

The successful testing of these three systems reflects our ongoing commitment to engineering excellence, product reliability, and long-term performance.

With the introduction of RG70, RG95, and RG80, REGWEN is now able to provide more certified, high-performance solutions for residential, commercial, and project-based applications across Europe and beyond.

REGWEN — engineered for performance, built for long-term value.
