Schüco AF UDC 80 – Dynamic Facade Platform for Maximum Flexibility

The Schüco AF UDC 80 (Aluminium Façade Unitized Dynamic Construction) is a dynamic unitized façade system offering a high degree of design freedom. This platform provides architects and designers an adaptable toolkit of components to create bespoke façades without starting from scratch. AF UDC 80’s scalable, tested assemblies make it easy to construct complex building envelopes with confidence in their performance and quality.

Commercial Application

Suited for office buildings, mixed-use complexes, and other commercial projects requiring a reliable curtain wall with design versatility. Whether the design calls for classic vertical ribbon windows or bold modern patterns, this system can adapt to various building styles and heights.
Design Versatility

AF UDC 80 offers modular flexibility. Architects can choose from various mullion depths and profile configurations to achieve the desired look – from emphasized vertical lines to a uniform grid. Cover caps are available to create different exterior aesthetics, including a slimmer sightline option for a sleek appearance. The continuous 80 mm profile width ensures visual consistency and maximum glass area, yielding bright interiors and impressive exterior transparency.
Robust Performance

Robust Performance: Despite its elegant lines, this system handles large panels and heavy glass with ease. Its strong aluminum profiles allow large unit dimensions and high unit weights, enabling floor-to-ceiling glazing in commercial towers. All units are thermally broken for energy efficiency, and the system integrates advanced sealing and drainage to achieve outstanding weather tightness under extreme conditions.
Efficient Fabrication & Installation

The UDC 80 platform is engineered for efficient off-site fabrication and quick assembly. Its components are pre-tested and standardized, streamlining the curtain wall production process. During installation, the system’s clever design accommodates building movements and tolerances, ensuring a precise fit. This translates to faster enclosure of the structure and reduced on-site adjustments – critical for tight construction schedules.
Integrated Sun-Shading Option

Uniquely, Schüco AF UDC 80 can incorporate a concealed textile sun-shading system (Schüco AB ZDS) within the façade. This built-in solar shading, which remains stable even in wind, helps reduce cooling loads and glare without disrupting the façade’s clean lines. Such integration exemplifies a user-centric design, keeping occupants comfortable while preserving architectural unity.

Schüco AF UDC 80 SG – All-Glass Aesthetic with Structural Glazing

For projects desiring a flush, uninterrupted glass façade, Schüco AF UDC 80 SG (Structural Glazing) is the perfect choice. This variant delivers a dynamic unitized façade with an all-glass look– from the exterior it appears as a continuous plane of glass, with minimal aluminum visible. Internally, it still uses the 80 mm module system, ensuring structural strength and integration with other UDC 80 components.

Commercial Application

Ideal for high-end corporate headquarters, commercial towers, and institutional buildings aiming for a sleek mirror-wall appearance. It’s often used where modern aesthetics and prestige are paramount – such as landmark skyscrapers or luxury hotels – providing a seamless glass curtain wall that reflects the sky and city.
Sleek All-Glass Facade

AF UDC 80 SG achieves an expansive glass curtain wall effect. Externally, the framing is concealed behind structurally bonded glass panels, creating a smooth glass surface that maximizes reflection and transparency. This system allows architects to emphasize light and openness, blurring the boundaries between inside and out.
High Energy Performance

Despite its minimalist appearance, the system delivers high thermal insulation (Uf values up to ~1.3 W/m²K) and robust performance against air and water infiltration. The structural glazing is paired with advanced thermal breaks and insulation, ensuring the building remains energy-efficient and comfortable. Large unit sizes are possible, enabling panoramic views without compromising performance.
Design Flexibility

AF UDC 80 SG supports creative façade designs – including horizontally offset units and integrated opaque panels for visual interest. Designers can introduce features like fritted glass spandrels or sloped glazing accents while maintaining the all-glass look. The system accommodates three bonding methods (direct structural bonding, adapter profiles, or glass replacement frames) for attaching glass, offering flexibility in fabrication and future maintenance.
Integrated Operable Ventilation

Even with its seamless exterior, the SG system can include large insert windows (top-hung or parallel opening) using Schüco’s concealed AWS 114 SG vent technology. These operable panels are virtually invisible from the outside (thanks to stepped glass and hidden frames), providing natural ventilation without disrupting the facade’s flush appearance. Users inside can enjoy fresh air, while the outside retains a uniform glass skin – a perfect balance of form and function.

Schüco AF UDC 80 CV – Concealed Vent Façade for Transparency and Comfort

The Schüco AF UDC 80 CV (Concealed Vent) façade system is a highly transparent unitized curtain wall with hidden opening units. It is engineered so that even operable windows are completely concealed within the façade framing, maintaining a clean, continuous look. This design sets new standards by combining ventilation functionality with an uncompromised all-glass appearance.

Commercial Application

Suited for modern offices, hospitals, or educational buildings where natural ventilation is desired without the look of traditional windows. It’s particularly valuable in climates or building designs focused on fresh-air cooling or mixed-mode ventilation – offering the ability to open sections of the curtain wall for air flow while preserving the sleek exterior.
Invisible Operable Windows

User comfort meets design elegance. The CV system integrates projected top-hung or parallel-opening vents that are invisible from the outside. With a face width of just 80 mm, the frames of these vents align seamlessly with fixed panels, ensuring uniform façade transparency. Occupants can open sections for ventilation, but when closed, even a keen eye can hardly distinguish them – the façade reads as continuous glass.
Seamless Aesthetics

From the exterior, AF UDC 80 CV is indistinguishable from the standard UDC 80 system. This means you get all the benefits of operable units without any visual penalty. The interior design is equally minimal; the only hint of an operable unit is a discreet handle on the inside. This fidelity in design is ideal for architects striving for absolute visual purity in their glass facades.
Structural Capacity & Performance

The concealed vents are engineered to handle large sizes and heavy glass (up to ~1000 kg per panel, depending on design). Even with operable functionality, these units maintain high structural integrity and weather resistance. The system’s flexibility allows integration of large fixed glass panes and opening units on the same module, all tested for air-tightness and water-tightness under demanding conditions. The facade remains robust against wind loads, ensuring safety at great heights.
Design Harmony

AF UDC 80 CV supports combining fixed and operable panels freely, giving designers and building users the freedom to place ventilation where needed (for example, every third panel can open for air, without any pattern visible externally). This approach fosters a user-centric environment – fresh air and natural ventilation can improve occupant well-being – while the building retains a crisp, modern facade. It’s truly innovation in service of the user, packaged in an elegant solution.
