There are several types of pergola. Here are the differences: 1. Winding canvas pergolas. The canvas always remains taut regardless of the weather conditions. For this pergola, we recommend you use the Pergola io motorised system. 2. Folding canvas pergolas. Its PVC-coated canvas gives you dual protection against the sun and rain. For this pergola, we recommend you use the Pergola io motorised system. 3. Adjustable slat or bioclimatic pergolas. Their aluminium structure and adjustable slats protect you perfectly from the sun and rain. For this pergola, we recommend combining the Pergola Tilt 24V io motorised system with the Pergola Tilt io control unit with built-in weather io sensors.
