How are roof windows operated?

Manual

Roof windows are opened or operated manually through a window handle at the bottom or a handle strip at the top of the window casement. Residential roof windows from the manufacturer ROTO have a so-called handle operation. Like a façade window with tilt and turn fitting, the casements are folded or turned depending on the handle position (see also Opening Types). The window handle is located at the bottom centre of the cross profile of the window casement in these roof windows. Hinged and pivoted windows from the manufacturer VELUX have two handles. The lower handle is used for folding. The upper handle for swinging the casement.

Electric

Roof windows can also be opened electrically – by a motor. Depending on the area of application of the skylight, the motors can be visibly attached to the underside of the frame (e.g. for smoke ventilation windows) or invisibly. In the case of pivoting windows, a chain motor is usually mounted in the upper area of the window frame, below the sunblind box. This motor then opens the roof window using a radio signal (hand-held transmitter) or button impulse (switch) from above and allows the window casement to rise approx. 20 cm.

The manufacturer ROTO offers a unique feature. Here, top-hung swing windows are possible, which fold the window casements up to 45° with concealed motors.

Of course, sliding roof windows are also available with electric operation on request.
