Luxury thermally broken steel facades are designed to create transparent building envelopes that connect interior and exterior spaces. Brombal develops custom curtain wall systems for high-end architecture, enabling large glass surfaces, structural performance, and refined minimal aesthetics.
What Are Thermally Broken Steel Facades?
Thermally broken steel facades—also known as curtain wall systems—are large-scale glazing structures that use steel profiles with an integrated thermal barrier to reduce heat transfer.
These systems create a continuous external envelope made primarily of glass, supported by high-strength steel structures.
In simple terms:
- Steel provides structural support for large glass surfaces
- The thermal break improves insulation
- The result is a high-performance architectural facade
They are widely used in luxury architecture to achieve transparency, light, and visual continuity.
What Is a Steel Curtain Wall System?
A steel curtain wall is a non-load-bearing facade system designed to enclose a building while supporting large expanses of glass.
Brombal curtain wall systems offer:
- Slim thermally broken steel profiles
- Large-format glazing
- Integration of operable windows and doors
- Full customization based on architectural design
These systems act as both a design feature and a high-performance building envelope.
Why Steel Facades Are Used in Luxury Architecture
Steel is the preferred material for high-end facade systems due to its superior structural properties.
Key advantages include:
- Exceptional strength → supports very large glass panels
- Slim sightlines → maximizes transparency and natural light
- Architectural precision → enables complex geometries
Compared to other materials, steel allows architects to push the limits of façade design.
Steel Facades vs Aluminum Curtain Walls
Material choice significantly impacts both performance and aesthetics.
Steel vs Aluminum:
- Steel is stronger → allows thinner mullions
- Aluminum requires thicker profiles
- Steel offers a more refined and minimal appearance
- Steel can achieve higher structural performance in large facades
Conclusion:
Steel curtain walls are ideal for projects where design precision and structural performance are critical.
Energy Efficiency and Thermal Performance
Modern steel facade systems are engineered to meet strict energy performance standards.
The thermal break within the steel profiles reduces heat transfer, improving insulation across the building envelope.
Performance benefits include:
- Reduced energy loss
- Improved indoor comfort
- Integration with solar-control and high-performance glass
These systems support sustainable and energy-efficient building design.
Design Possibilities with Steel Facades
Steel facades unlock architectural possibilities that are difficult to achieve with other materials.
They are ideal for:
- Full glass building envelopes
- Floor-to-ceiling facades
- Complex geometries and custom structures
- Seamless integration of windows and doors
Their minimal profiles allow uninterrupted views and a strong visual connection between interior and exterior spaces.

Frequently Asked Questions
What is a steel curtain wall?
A steel curtain wall is a facade system made of glass panels supported by a steel structure. It is not load-bearing but acts as the building’s external envelope, providing protection while maximizing transparency and light.
Why use steel instead of aluminum for facades?
Steel is stronger than aluminum, allowing for slimmer profiles and larger glass surfaces. This results in a more refined aesthetic and better structural performance, especially in large-scale or complex facade systems.
Can steel facades include operable windows and doors?
Yes, steel curtain wall systems can integrate operable windows and doors within the facade. This allows for ventilation and access while maintaining a consistent design across the building envelope.
Are steel facades customizable?
Steel facades are fully customizable and designed to meet specific architectural requirements. Systems like those from Brombal are engineered to adapt to unique geometries, materials, and performance needs.
How durable are steel facade systems?
Steel facade systems are highly durable and designed to withstand environmental stress, including wind loads and weather exposure. They offer long-term performance with minimal maintenance.
Are steel facades suitable for residential projects?
Yes, steel facades are increasingly used in luxury residential architecture, especially for villas and modern homes that emphasize large glass surfaces and indoor-outdoor continuity.
What is the difference between a curtain wall and a facade?
A curtain wall is a type of facade system that is non-load-bearing and typically made of glass supported by a structure. It acts as the building’s outer skin while maximizing transparency.
Are steel facades suitable for large buildings?
Yes, steel facades are ideal for large-scale buildings because of their structural strength. They can support extensive glass surfaces while maintaining slim profiles and high performance.
Can steel facades improve natural light in buildings?
Yes, steel facades maximize natural light by allowing large glass panels with minimal structural interruption. This improves interior brightness and enhances the connection with outdoor spaces.
