Self-regulating window vent DUCOTOP 60 'SR' AK+

acoustic

Sitting on top of the window frame, the vent is almost invisible. It does not interfere with the designed U value of the complete window. The integrity of the window frame and glazing is untouched. The DucoTop 60 'SR' sits on top of any style of window frame, uPVC, aluminium or timber. From 68 to 188 mm in depth, and creates no visual distraction to the window. It removes the fitting of a vent from the window manufacturing process. The self regulating vent equalizes the airflow thus avoiding uncomfortable draughts.The DucoTop 60 'SR' range is further enhanced by the addition of the DucoTop 60 'SR' AK+ for locations with higher noise levels.
