Glazed-in Vents

Glazed-in, or overglass ventilators are custom-made to size and installed during fabrication to fit along the top of the sealed glass unit. They deliver a constant airflow without having to actually open the window or compromise security. Glazed-in vents are ideally suited to installations that demand higher levels of airflow or where there is no room for a trickle vent on the frame or where the window recess prohibits their use.
