UPVC (unplasticized polyvinyl chloride) windows offer superior insulation, durability, and aesthetics. To enhance their functionality, friction stays are an essential hardware component that holds the window sash open at various angles, providing ventilation and ease of use. Installing friction stays on UPVC windows is a straightforward process that can be completed with basic tools and a bit of preparation. This step-by-step guide will provide precise instructions to ensure a successful and secure installation.

Tools and Materials Required

Friction stays

Measuring tape

Pencil or marking tool


Screwdriver or socket wrench

Foam tape (optional)

Lubricant (optional)

Installation Preparation

1. Measure and Mark

Determine the desired location for the friction stays on the window frame and sash. Measure and mark the center point for each stay on both the frame and sash using a pencil or marking tool.

2. Determine Screw Length

The screw length should be sufficient to penetrate both the frame and sash without exceeding the thickness of the sash. Measure the thickness of both sections and add approximately 10mm to determine the appropriate screw length.

Installation Steps

1. Install Frame Bracket

Place the frame bracket of the friction stay onto the marked location on the window frame. Align the bracket and secure it using the supplied screws. Ensure that the bracket is level and flush with the frame.

2. Install Sash Bracket

Position the sash bracket of the friction stay onto the marked location on the window sash. Align the bracket and secure it using the supplied screws. Make sure the bracket is parallel to the frame bracket and slides smoothly within its track.

3. Lubricate (Optional)

To ensure smooth operation, apply a small amount of lubricant to the moving parts of the friction stay, such as the pivot point and sliding track. This will reduce friction and enhance durability.

4. Install Friction Stay

Insert the friction stay into the installed frame and sash brackets. Align the stay and slide it into the brackets until it clicks into place. Ensure that the stay pivots freely and provides the desired friction when opening and closing the window.

5. Adjust Friction

The friction level can be customized to suit individual preferences. Tighten or loosen the adjustment screw on the friction stay using a screwdriver or socket wrench. Turning the screw clockwise increases friction, while turning it counterclockwise decreases friction. Adjust the stay until it provides the desired resistance.

Additional Tips

Use foam tape between the friction stay and the frame to seal any gaps and prevent rattling.

If the screw holes do not align perfectly, use a drill to create new holes to ensure proper alignment.

Ensure that all screws are fully tightened, but avoid overtightening.

Periodically check and lubricate the friction stays to maintain smooth operation and extend their lifespan.
