Minimal Curtain Wall System
A façade this size is not really about glass — it’s about how little is allowed to stand in front of it. Ultra-slim aluminium framing recedes behind expansive glazing, letting a building read as light and transparency rather than structure. Capped, semi-structural, or fully structural silicone glazing options push that transparency further still, toward a face that reads as almost entirely glass.
None of that scale comes at the cost of performance. Thermally broken profiles, heavy-duty mullion and transom systems, and pressure-equalized drainage are engineered to hold their integrity across vertical façades, sloped glazing, skylights, atriums, and canopies alike — accommodating thermal movement and differential building movement without ever showing the strain. It is a system built for the scale of towers and landmark developments, where architectural ambition and engineering precision have to move together.
1. Ultra-Slim Sightlines
Minimal visible aluminium profiles maximize glass area, creating clean, uninterrupted architectural lines across even the largest façade.
2. Structural Glazing Options
Capped, semi-structural, or fully structural silicone glazing configurations allow the façade to achieve a seamless, near all-glass appearance where the design calls for it.
3. Thermally Broken Aluminium Profiles
Advanced polyamide thermal barriers significantly reduce heat transfer through the frame, improving whole-building energy efficiency at scale.
4. Large Glass Panels
The system supports oversized glazing units, enabling dramatic floor-to-ceiling façades that bring in exceptional natural daylight.
5. Flexible Architectural Design
The same system adapts across vertical façades, sloped glazing, skylights, atriums, canopies, and custom curtain wall applications, without compromising performance.
6. Exceptional Weather Performance
Engineered for demanding environmental conditions, the system delivers superior resistance to air infiltration, water penetration, and wind loads at façade scale.
