Hello,
We are planning to install a cassette awning on our terrace. We live in an area where it can occasionally get quite windy. According to major manufacturers, most awnings are designed for wind speeds up to force 5 on the Beaufort scale.
Is there anyone here who has installed an awning in a windy area and can share what these products can really withstand? We are concerned about light wind. In strong wind, we would not use the awning anyway.
Thank you very much!

WilderSueden30 Jun 2023 15:54How large should it be? And what exactly do you consider light and strong wind to be—wind speed or wind force?
I did some research for us and found that a range of 3-4 on the Beaufort scale is suitable for an awning. As a sailor, I have to say that 5 Beaufort is already quite strong wind and can be powerful. When you consider this, don’t forget that gusts can be significantly stronger than the steady wind.
We are also quite exposed to wind here, located on a hill with relatively open exposure to the west. That’s why we chose a patio roof with an integrated under-roof awning. Alternatively, you could consider a pergola awning and skip the glass roof.

ateliersiegel30 Jun 2023 16:32We have a motorized awning equipped with a safety mechanism that automatically retracts it when a preset level of vibration is detected.
The awning should be about 5.5 to 6 meters (18 to 20 feet) wide. We actually don’t want a pergola awning because of the visible frame.
Even a light wind makes the bushes sway, and you can really feel the breeze. We would also consider a wind sensor.
Most awnings have a wind resistance class of 2, which corresponds to 5 on the Beaufort scale. That shouldn’t be too low.

WilderSueden30 Jun 2023 23:15The width is not that important, but how far do you want to extend it? It easily goes over 3 meters (10 feet), and with today's common terraces, often significantly more. This puts considerable leverage on a small threaded rod. Not only is the awning itself relevant for wind resistance, but also how it is fastened. Nowadays, even solid masonry structures aren’t very stable (thermal insulation means walls mainly consist of air...), so mounting is usually done into the ceiling between floors. However, you first have to drill through some kind of insulation... you can’t compare this to screwing the awning directly into a concrete or old solid wall.
At least I’m not comfortable with that idea. And I want to be able to sit in the shade when it’s windy. It sounds easy now, but later it will definitely be annoying if the awning retracts in the wind.
