ᐅ Awning, Shading – A Guide to Choosing

I need some advice regarding an awning.
Our terrace faces south and measures 10 meters (33 feet) wide and 4.30 meters (14 feet) deep. Since it gets quite warm in summer, we need some shade. We don’t want umbrellas. Originally, we considered a fixed roof, but we discarded that option because 1. it is too expensive, and 2. we don’t like the posts.
You enter the terrace through a sliding door on the right half and then sit on the left half.

Now I have two offers but can’t really decide. What do you think?

Option 1: Klaiber Resobox BX8000
ONE awning, 9.40 meters (31 feet) wide with a 4-meter (13 feet) projection.
+ Possibly looks better
- We like the cassette less than that of the BX4500

Option 2: Klaiber Camabox BX4500
TWO awnings placed directly next to each other: one 5 meters (16 feet) and one 4.4 meters (14 feet) wide, each with a 4-meter (13 feet) projection.
+ We like the cassette of this model much better
+ More flexibility in shading different sides of the terrace
- Gap between the awnings
- Both awnings must be installed perfectly to look right

Option 2 is about 300€ more expensive, which is not a decisive factor.

As mentioned, we have a south-facing side. This means that in summer, the sun shines directly into the dining room from the left side. We can’t lower the blinds there either, otherwise we won’t be able to get out.
Also, the sun moves toward the left, which means the left side is west. The sunlight then comes in from the side. From the afternoon/evening onward, we wouldn’t be able to sit in the shade anymore.
Next to the raised bed, there is now a water feature. It’s not finished yet, though. The netting and the stones around it are still missing.

Oh yes, regarding costs. Both options, including installation, would cost between €8,600 (Resobox) and €8,900 (Carmabox).

One more question about that. Do you think a large awning is more susceptible to wind than two smaller ones side by side? It shouldn’t really make a difference, right? Both are rated for wind resistance class 2, which corresponds to wind force 5.

Yes, a large awning is more susceptible to wind. Ours measured 5x4 meters (16x13 feet), and when extended with a light breeze, it would bend significantly. It basically acts like a sail. Due to the design, ours was also attached to the roof rafters because it wasn’t supposed to be fixed directly to the timber frame.

If the wind picked up too much, we retracted it. When we sold it in 2018, after six years, it still looked like new. We now have a fixed patio roof.

Yes. That’s basic physics. Ultimately, you are attaching a "sail" to the house. The forces involved are significant. Whether both have the same wind resistance rating depends on the design of the supporting structure.
The "smaller" option with two awnings (still large sails) also offers more flexible use.

Hmm, okay. I was almost back to considering the single awning again. Oh well, tough decision. I can already tell, once it’s installed... Murphy’s law...
