Contemporary architecture is increasingly pushing beyond the limits of classical dimensions. Large atriums, panoramic façades, sports and business halls, and luxury residential buildings require external shading systems that are not only aesthetically refined, but also structurally uncompromising. Precisely for such demanding projects, Sunbreakers B290 were developed – the most powerful external shading system for the greatest architectural challenges.
What are Sunbreakers B290 and when should you choose them?
Sunbreakers B290 are external aluminium shading systems with exceptionally wide ellipsoidal blades measuring 290 mm in width. They are designed for buildings where standard Sunbreakers or conventional shading systems do not provide sufficient load-bearing capacity, stability, or protection.
They are ideal for:
- large glass façades,
- atriums and multi-storey glazing,
- commercial and public buildings,
- sports halls,
- luxury villas with open panoramic views.
Their key function is to stop solar energy before it reaches the glass, ensuring effective control of light, heat, and security even at extreme dimensions.
Spans of up to 4 metres without intermediate supports
The greatest advantage of the B290 system is its exceptional structural load-bearing capacity. The blades allow spans of up to 4000 mm (4 m) in a single piece, without intermediate supports or additional structural elements.
This means:
- an unobstructed view from interior spaces,
- clean, minimalist façade lines,
- fewer structural components,
- greater architectural freedom in design.
For large glazed surfaces, this is a crucial advantage, as it preserves spatial openness and the aesthetic value of the building.
Complete blackout even at extreme dimensions
Despite their size, the B290 system enables complete blackout. The blades are equipped with special overlapping lips that interlock when closed, preventing any light from passing through.
The result is total darkness within the space, which is extremely rare for shading systems of this scale. This makes it an ideal solution for:
- conference and presentation halls,
- hotel rooms,
- multimedia spaces,
- luxury bedrooms,
- buildings where precise light control is essential.
Extreme resistance to wind, hail, and mechanical loads
Sunbreakers B290 are among the strongest shading systems on the market. Their robust aluminium construction and reinforced internal structure ensure outstanding resistance to weather conditions.
The system withstands:
- hurricane-force wind gusts (tested at speeds exceeding 200 km/h),
- heavy rainfall and hail impacts,
- high mechanical loads.
In the closed position, the sunbreakers also act as additional anti-burglary protection, forming a solid metal barrier in front of glass surfaces.
Flexible installation and complete light control
The B290 system allows for:
- horizontal or vertical installation,
- fixed or movable configurations,
- blade rotation of up to approximately 150°.
The user has full control over:
- the amount of natural light,
- shading,
- privacy,
- outward visibility.
Control options are adapted to large-scale systems and include:
- motorised operation (recommended option),
- manual operation,
- integration into Smart Home systems with wind and sun sensors.
Energy efficiency for large buildings
Large glass surfaces are one of the main causes of building overheating. Sunbreakers B290 stop solar energy before it reaches the glass, significantly reducing the greenhouse effect.
Advantages:
- reduced need for air conditioning,
- lower cooling costs for large volumes,
- a more comfortable indoor climate,
- higher long-term property value.
Thanks to the large blades, air circulation between the shading system and the glass is even more efficient, further improving the building’s overall energy performance.
Sunbreakers B290 – when architecture demands the maximum
Sunbreakers B290 are not merely external shading devices, but a strategic architectural solution for buildings where size, safety, and aesthetics allow no compromises. They combine advanced engineering, contemporary design, and maximum functionality into a system capable of meeting even the most demanding projects.
When architecture goes beyond standards, B290 is the right choice.
