Manufacturing & Assembly
Engineered To Perform. Crafted To Endure.
At H.O. Schlüter, our commitment to precision and quality is brought to life inside our state-of-the-art 38,000 sq. ft. manufacturing facility — the heart of our operations and the place where innovation, craftsmanship, and engineering excellence converge.
We produce over 200 high-quality uPVC windows each day, making our facility one of the most productive of its kind in Germany. Since 1992, uPVC windows and doors "Made in Lübz" have earned a leading position in the market — recognized for their exceptional quality, fast delivery, and competitive pricing.
A balance of human expertise & digital precision.
Our facility is equipped with cutting-edge production machinery designed to meet the demands of modern construction, including short production timelines and increasingly complex design requirements. Every window and door we produce is the result of highly skilled specialists working in tandem with advanced technologies — a balance of human expertise and digital precision that ensures our products meet the highest standards, both technically and aesthetically.
To maintain our reputation for excellence, we’ve implemented fully computer-aided workflows that guarantee consistency and accuracy throughout every stage of production. In the world of high-performance windows and doors, precision isn’t optional — it’s essential. Whether it’s tight tolerances, thermal efficiency, or custom specifications, we believe accuracy is a defining quality feature, and we’ve built our entire production process around that principle.
Our manufacturing process is supported by an innovative, fully online production monitoring system, giving our team real-time visibility into every project’s progress. This is complemented by a robust inventory management platform that helps ensure seamless coordination of materials, optimized logistics, and on-time delivery — every time.
Our facility is backed by numerous industry certifications and approvals, validating not only the quality of our output, but also our adherence to international standards of safety, sustainability, and performance. These recognitions reflect our ongoing mission: to manufacture windows and doors that aren’t just built to specification — but built to last. From first sketch to final shipment, every product that leaves our facility is a reflection of our company values: precision, performance, and long-term reliability.
