This hi-flow frame trickle vent is designed for installation in window frames to provide continuous background ventilation. Measuring 525mm in length, it is suitable for use with a range of window types where controlled airflow is required.
On site, installers typically fit this trickle vent into the upper frame section, allowing fresh air to circulate while the window remains secure and closed. It helps reduce condensation and supports comfortable indoor air quality without compromising on security.
