TopVent BE SR (AK+)
Compact & aesthetic
With the TopVent BE range, DUCO puts energy efficiency and acoustic and thermal comfort first. This grille is the redeveloped version of the DucoTop 60 SR (AK+).
The aesthetic appearance of the grille is enhanced by the invisible punching. The upward airflow guarantees a healthy and comfortable indoor climate. The grille guarantees quick assembly, high stability on the window and the highest airtightness class. The top is transparent and fitted with pre-drilled fibreglass-reinforced ties. The anchor channel at the top provides a rapid and secure fixing to the solid structure.
A variant was specifically designed for the UK in line with current regulations: the TopVent UK . Here the internal ventilation flap is limited at the equivalent area to 5000, 7500 or 10000 mm. This is always performed in a sound-absorbing AK version. More information about the TopVent UK can be found in our .
