For areas with restricted access Velux Integra roof windows offer a simple solution. A fully programmable control pad can operate the window, blinds, awnings, and shutters individually or in groups. Easily installed by just plugging into a power supply the fully integrated motor runs almost without a sound. The control pad can be used within 20 metres of the window.
Velux solar powered windows have all the same features as Integra but a PV solar cell on the external side of the window powers the motor from the sun. NB PV cell requires direct exposure to sunlight.
