What is the wind resistance of BSOs?
Wind resistance tests were carried out by the Civil Engineering Centre (Centrum stavebniho inenyrstvi, as) in Zlin in accordance with SN EN 13659 .

What is the standard for wind resistance of a sunshade?
In Europe, the standard that governs this is EN 13659 :2015, which concerns external shutters and sunshades. EN 13659:2015 defines the performance and safety criteria for external shutters and sunshades.
It specifies requirements for thermal performance, wind resistance, burglar resistance, safety of use, operational durability, and fire behavior.
For wind resistance in particular, products are rated from 0 to 6 , where 0 is the lowest and 6 is the highest in terms of resistance.
The class is determined by tests carried out in specialized laboratories. For an adjustable sunshade, we will seek to obtain a fairly high wind resistance class, because these are products that are often used outdoors and must withstand bad weather.

Here is a simplified version of this standard:
| Class | Approximate wind pressure | Application example |
|---|---|---|
| 0 | < 20 km/h | Interior, highly protected areas |
| 1 | 20 - 39 km/h | Low wind areas, sheltered areas |
| 2 | 40 - 59 km/h | Moderate wind areas, suburbs |
| 3 | 60 - 79 km/h | Stronger wind areas, coastal areas |
| 4 | 80 - 99 km/h | Windy areas, coastal areas with strong winds |
| 5 | 100 - 119 km/h | Areas with very strong winds, mountains |
| 6 | 120 km/h and more | Extreme wind areas, high altitude mountains |

Frequently asked questions about sunshades and wind
1. What is an adjustable sunshade ( BS )?
An adjustable sunshade is a type of exterior sun protection made up of tilting blades. It allows you to control the amount of incoming light while preserving the view to the outside.
2. Are the adjustable sunshades wind resistant?
Yes, BSOs are designed to withstand certain wind forces, according to EN 13659:2015. However, their resistance depends on their wind resistance class.
3. How is the wind resistance of a BSO classified?
The wind resistance of a BSO is classified from 0 (low resistance) to 6 (exceptional resistance), according to the EN 13659:2015 standard.
4. What is the effect of wind on a BSO?
Too much wind can damage a BSO, especially by making it vibrate or deform it. This is why it is important to choose a BSO that is suitable for the installation area.
5. Can BSOs be used in windy weather?
Yes, but it is recommended to close them or put them in a safe position in strong winds to avoid damage.
6. How to choose a BSO based on its wind resistance?
First, you need to assess the climatic conditions of the place where it will be installed. Then, choose a BSO with an appropriate wind resistance class.
7. Is a higher class BSO always better?
Not necessarily. A higher class BSO will be more wind resistant, but it can also be more expensive. The important thing is to choose one that suits your specific needs.
8. How to check the wind resistance class of a BSO?
The wind resistance class should be indicated by the manufacturer. If not, do not hesitate to ask.
9. Can BSOs be damaged by wind?
Yes, too much wind can damage your outdoor blind, especially if it has a lower wind resistance class than that required for the installation area.
10. What should I do if my BSO is damaged by wind?
It is recommended to contact the manufacturer or a professional to assess the damage and make the necessary repairs.
