Sunbreakers B290 – Protection for the Largest Architectural Challenges

Sunbreakers B290 represent the peak of engineering performance in the field of exterior shading systems. When standard solutions are not enough, the B290 system takes over. With an exceptionally wide elliptical blade of 290 mm and a reinforced internal structure, this system is designed for shading the largest glass surfaces, atriums and facades, where uncompromising stability and clean aesthetics are required.

Span up to 4 meters without intermediate supports

The main advantage of the B290 model is its structural superiority. It is engineered to bridge extreme spans of up to 4000 mm (4 m) in a single piece.

“Blackout” technology even at the largest dimensions

Despite the size, the system ensures precise sealing. The blades feature integrated overlap wings at the ends, which lock together when closed.

Severe weather protection

Sunbreakers B290 are the strongest shading systems in our offer. Their massive aluminum structure acts as a shield:

Versatile installation and applications

The B290 system is ideal for commercial buildings, sports halls and luxury residential homes. The blades may be installed in a vertical or horizontal orientation, allowing architectural manipulation with shade across the façade.

Controlling large systems

Due to the weight and size of the blades, the system is optimized for motorized operation, though other options are available:

Blades can rotate up to approx. 150 degrees, giving precise control over the amount of indoor light.

Technical specifications

We use only the highest-quality extruded aluminium to ensure long-term structural stability.

Energy savings for large buildings

Large glass surfaces are the main cause of building overheating. Sunbreakers B290 stop the solar energy before it reaches the glass. Due to their size, air circulation between the blades is even more effective, drastically reducing cooling energy consumption in large-volume spaces.

Frequently Asked Questions (FAQ)

1. Why choose B290 instead of B220?
The key reason is span capacity. If you have a glass wall between 3.2 m and 4.0 m wide and want to shade it in a single uninterrupted span (without an intermediate column), B290 is the only correct solution. Visually, B290 also appears more powerful and proportionate on very large façades.

 

2. Is a 4-meter-long louver stable in strong winds?
Yes. The B290 louver is specially engineered with reinforced internal walls and increased mass. Despite its 4-meter length, it is statically stable and withstands wind speeds of up to 200 km/h without twisting or vibration.

 

3. Can the motor handle such heavy louvers?
Yes. The B290 system uses specialized, high-performance linear motors designed for heavy loads. Operation is smooth and quiet, while allowing precise positioning of the louver angle.

 

4. Can the B290 system be used as a canopy or roof?
Absolutely. B290 louvers are often used as a fixed roof for canopies or as a rotating roof (pergola). Thanks to their 290 mm width, fewer louvers are needed to cover the same area, creating a more open and airy ceiling appearance.

 

5. Do such massive louvers darken the space too much?
No, because you have full control. When the louvers are open (up to 150°), the wide spacing between them allows a large amount of natural light to enter. When closed, the overlapping edges ensure complete blackout.

 

6. Is vertical installation possible at a height of 4 meters?
Yes. Vertical installation of B290 louvers up to a height of 4 meters is a striking architectural solution that adds a strong vertical accent to the building and provides excellent protection against low-angle sun.
