Yes, the Velux top hung windows are very popular because of their opening style. A top hung window can be completely opened to allow maximum airflow and daylight. This allows for uninterrupted views, as well as a fire escape if necessary. If used as an escape window, it must be a minimum of 450mm x 750mm and be installed 600m (min) – 1100mm (max) from the floor. Contact your local Building Control department for more information.
