What is a trickle vent?


A trickle vent is a small, adjustable air vent typically located at the top of a window frame. Its primary purpose is to allow a controlled amount of fresh air to enter a room while maintaining the window closed. This helps improve ventilation and reduce humidity levels, which can prevent issues like mold growth and improve indoor air quality. Trickle vents can also contribute to energy efficiency by allowing for better airflow without needing to open windows completely.
