Multi-Chamber Design
Multiple internal chambers enhance strength and thermal performance.
SG ALUMINIUM SPECIALITY
A dedicated look at the design thinking, profile engineering and documented performance that set SG Aluminium systems apart.
Explore the difference ↓WHY SG ALUMINIUM
Our speciality lies in approaching aluminium as an engineered building system. Profile geometry, chamber design, glazing compatibility, hardware coordination and fabrication precision all work together to influence how a door or window performs in the real world.
That system-led approach gives architects, designers and homeowners a clearer reason to specify SG Aluminium beyond surface aesthetics alone.
THE PROFILE, EXPLAINED
Explore the anatomy of a performance-focused aluminium profile and the design considerations that can help distinguish a specialist system from a standard frame.
Multiple internal chambers enhance strength and thermal performance.
1.6 mm - 3 mm nominal wall thickness for higher durability and structural stability.
High-performance EPDM gaskets ensure a tight seal, improved weather resistance and long-term durability.
Designed to accommodate a range of glazing options for optimal insulation and performance.

THE SG DIFFERENCE
Profiles, glazing, seals and hardware are considered together to create a more resolved architectural system.
Configurations can be adapted around opening size, architectural intent and the practical requirements of each project.
Where applicable, documented testing gives clients a more transparent basis for evaluating the system beyond marketing claims.
Clean junctions, controlled sightlines and coordinated finishes help performance-led engineering remain visually refined.
