Trickle_vent
A trickle vent is a very small[quantify] opening in a window or other building envelope component to allow small amounts of ventilation in spaces intended to be naturally ventilated when major elements of the design – windows, doors, etc., are otherwise closed.[1][2] Trickle vents are used extensively in Europe and are integrated into window frames to provide minimum ventilation requirements for naturally ventilated spaces.
