REHAU |Run Through Sash Horns Manufactured at Fenster

---

At Fenster Trade Frames, we manufacture run-through sash horns using REHAU uPVC window systems, providing trade installers, builders, and specifiers with a product that combines period charm with modern performance.
Unlike clip-on or stick-on alternatives, our sash horns are milled directly into the frame, creating a seamless, timber-like appearance that replicates traditional joinery while maintaining all the benefits of uPVC, low maintenance, strength, and energy efficiency. 

Our manufacturing facility is equipped to handle large-scale production runs, allowing us to meet even the most demanding production schedules. We have the capacity to produce thousands of units per day without sacrificing quality or efficiency.

Because every unit is manufactured at our own facility, we keep lead times short and prices competitive. You get factory-direct trade value without compromising craftsmanship or quality. Our advanced equipment and quality-assurance process mean installers can fit confidently, knowing each window meets REHAU’s exacting standards. 

REHAU run-through sash horn windows achieve Part L energy compliance and can meet PAS 24 security ratings, offering homeowners exceptional performance and peace of mind. They provide the heritage look your customers want, paired with the durability, weather resistance, and thermal efficiency your business relies on. 

At Fenster, we work collaboratively with trade partners to deliver solutions that help win more projects. Whether you’re pricing a period property or designing for a conservation area, our team provides the product support, marketing materials, and expert advice you need to present REHAU sash horns with confidence.
