– A Practical, Safe, and Modern Window Solution
As architectural design continues to evolve towards simplicity, functionality, and safety, aluminum windows have become the preferred choice for residential, commercial, and public projects. Among all the window hardware, one small but crucial component makes a major difference — the friction stay for windows.
Though often overlooked, friction stays determine the smoothness, safety, and long-term reliability of window operation. For contractors, hardware importers, and construction buyers seeking high-quality window systems, choosing the right friction stay directly impacts product performance and customer satisfaction.

✅ What Is a Friction Stay for Windows? What Does It Do?
A friction stay is a window hinge mechanism installed between the sash and the frame. It typically consists of stainless steel arms, sliders, friction pads, and riveted joints. Compared with traditional hinges, friction stays offer these key functions:
- Multi-angle opening & self-positioning
The window can remain open at various angles without additional support arms, reducing safety risks caused by wind or gravity. - Space-saving and modern design
Installed inside the window frame, it doesn’t interfere with interior space or accessories like curtains or insect screens – ideal for minimalist or modern home design. - Improved safety for daily use
Particularly effective in preventing accidental window slamming, especially in children’s rooms or high-rise buildings. - Smooth and silent operation
High-quality friction stays provide quiet, effortless window opening and closing, enhancing the overall user experience.
✅ Common Applications and Benefits of Friction Stays
Friction stays are suitable for many aluminum window systems, especially the following types:
✔ Top-hung Windows
Commonly used in kitchens, bathrooms, or basements. Friction stays hold the sash securely when opened upward, protecting against wind or accidental closure.
✔ Side-hung Casement Windows
Ideal for bedrooms, living rooms, and offices. Friction stays allow smooth side opening while maintaining ventilation and ensuring stability.
✔ High-rise External Windows
In tall buildings, window safety is critical. Friction stays ensure sashes remain steady even under wind pressure, reducing maintenance risks and increasing security.
