How to select the right motorised system for your pergola

There are several types of pergola. Here are the differences: 
1. Winding canvas pergolas. The canvas always remains taut regardless of the weather conditions. 
2. Folding canvas pergolas. Its PVC-coated canvas gives you dual protection against the sun and rain.
3. Adjustable slat or bioclimatic pergolas. Their aluminium structure and adjustable slats protect you perfectly from the sun and rain.
