In brief: Conservatory shading (above-roof or below-roof awning) is driven by a 45 mm tubular motor. Automation with sun and wind sensors makes sense so that the conservatory does not overheat in summer. Combined with electric roof windows, this creates a climate package of shading and ventilation.
Choosing the motor
| Application | Motor | Net price |
|---|---|---|
| Above-roof awning, wall switch | A-OK AM45 mechanical (15–50 Nm) | from 65 € |
| mit Funk, Hinderniserkennung, Zeitsteuerung | A-OK AM45 radio (6–30 Nm) | from €100 |
| mit Nothandkurbel und Wind-/Sonnensensor | A-OK AM45E (30–50 Nm) | from €125 |
The required torque depends on area, fabric weight and tensioning system – send us the dimensions of the system.
Combining shading and ventilation
Shading alone is rarely enough in summer: the warm air also has to get out. Electric roof windows with chain or linear actuators open automatically in heat and close when it rains. More on this: Automatic conservatory ventilation.
Automation
- Sun sensor: extends the shading in strong sunlight.
- Wind sensor: retracts it in a storm (especially important for above-roof awnings).
- Timer: fixed times, e.g. close at midday.
Frequently asked questions
Interior or exterior shading?
Exterior shading keeps out much more heat but is exposed to wind and weather – so plan a wind sensor.
Can I convert existing crank systems?
Often yes, by replacing the crank with a tubular motor in the fabric shaft.
