What types of shutters can be automated?
Rolling and hinged shutters can be automated, and there's nothing fancy about selecting the right type of motor: it's just a matter of shifting the weight!
Since the shutter drive is installed under the lintel of the window frame, its width must be appropriate to that of the window frame.
How to calculate the weight of your shutter?
PVC weighs about 4kg per m² for typical slat thicknesses up to 8mm; assume 5.5kg for thicker slats up to 14mm thickness.
Aluminium is significantly heavier than PVC, at around 4.5kg for slats up to 8mm and 6kg up to 14mm thickness.
It is therefore necessary to measure the width of the window frame - from one side to the other - and multiply it by the height (adding 20cm to account for the extra slats going as far as the shaft inside the shutter housing).
Example of automating a PVC roller shutter (8mm slat thickness)The window frame, where the shutter rollers will be fixed, is 1.15m high and 1.20m wide, i.e. [(1.15 + 0.20) X 1.20] = 1.62 m²
This area is then multiplied by the material weight per m², ie 1.62 X 4 = 6.48 Kg
How to determine the necessary lifting force?
Depending on the material, the force needed to lift your shutters will differ. This force is expressed in Newton metres (Nm) and is calculated very simply by multiplying the weight of the apron by 0.7!
The minimum force required to lift the shutter is therefore 4.53Nm.
Characteristics of rolling shutters
Just like with roller shutters, the diameter of the shaft is important because this is where the drive motor is housed. The effective diameter of the motor must be smaller than that of the shaft.
Long roller shutters have a powerful return spring inside the shaft, which compensates for the weight of the apron. Watch your hands!
Choosing a hinged shutter drive
Drives for hinged shutters come in the form of complete kits to be installed under the lintel.
Re installation: just a little cutting to do!
Shutter automation: wireless or not?
For optimum user comfort:go for remote control!
Radio-controlled motors allow remote opening and closing of the shutter and the most sophisticated models can even be operated from your Smartphone.
Remote controls can control one or more shutter drives via separate channels.
Shutter automation options
A timer will let you automatically open and close your shutters according to settings chosen in advance. Programming can be daily, weekly or monthly.
Generally - as explained above - drive motors are sold in the form of kits and the manufacturers just provide the essential information so you can make the right choice with ease: maximum shutter weight and area, minimum and maximum shutter width, minimum depth of window frame, etc.
Automation of entryways - such as a motorized gate - will enhance the comfort and security of your home.
