Upgrade your existing window to a solar-powered remote-controlled window

Control your existing windows with the flexibility and convenience of remote control. The VELUX conversion kit KSX 100K WW upgrades your manually-operated VELUX roof window produced after February 2014 to function like a solar-powered VELUX electric roof window.

This solar-powered window conversion kit is the perfect solution to transform you manually-operated centre-pivot roof window into a solar-powered roof window with the same functionality as the VELUX electric series. It is easily installed in manually-operated windows and doesn't require wiring. It's a great solution for adding convenience and functionality to your existing window. 

The solar-powered conversion kit includes a rain sensor that automatically closes the window if it rains and a wall switch.

For centre-pivot roof windows GGL & GGU produced after Febuary 2014. For windows produced before 2014, see KSX 100 WW.
