The most important factors are size, model, placement, and how much shade you need. The awning should fit the dimensions of your patio, the facade, and how you use the space. A larger awning provides more shade but also puts more strain on fixing, so plan everything together.
The width and projection should cover the part of the patio where you need shade. Open awning, half cassette, and full cassette provide varying degrees of protection for the fabric and arms. The mounting height, the building’s facade design, and the doors and windows all affect the placement. Choose the fabric and colour to match the facade, and manual crank, a motor, or an automatic system depending on how often awning is used.
