Slim uPVC Window Trickle Vents for Quiet Airflow

Shengxin’s uPVC window trickle vents provide a reliable and unobtrusive solution for controlled background ventilation. Designed specifically for integration into uPVC window frames, these vents are easy to operate, lightweight, and highly resistant to weathering. With a manual slider to open or close airflow, they help reduce condensation and improve indoor air exchange, especially in well-sealed buildings. Ideal for both new builds and refurbishment projects, these vents offer quiet performance and minimal visual impact.

Usage Tips

• For best performance, install on the upper part of the uPVC window sash
• Slot or drill guides should match the vent’s airflow opening
• Ensure the sliding flap opens smoothly before final installation
• Do not over-tighten screws to avoid damage to plastic housing
• Avoid installing in non-uPVC frames, as fit and performance may vary
