Designed primarily for use at the top of windows or in transoms, the 'Aerovent' has a generous weather hood on the outside and is opened or closed on the inside by a slide. The airflow is through a series of vertical slots that are hidden from view, and the slide is a U-channel that also deflects air movement to prevent draughts.

The Aerovent replaces the previously available Truvent product and features an internal insect mesh barrier. It is applied full length across the head of the window and can be incorporated into mainstream residential fixed windows and Metro Series windows. Placement at the bottom of the frame at sill level is also possible.

Powder coated zinc end caps are applied to each end of the exterior weather hood.

The Vented Sash option for trickle ventilation through the bottom rail of an awning sash is also available.
