System Benefits
Why use a thermal break?
A thermal break reduces the direct conductive path between the interior and exterior aluminium sections. Actual whole-window performance depends on the complete frame, glass, seals, installation and project conditions.
Thermal Separation
Insulating elements interrupt direct heat transfer through the aluminium frame.
Clean Detailing
Performance-focused construction can still maintain a modern architectural profile.
Glazing Integration
Frame and glass selection should be considered together as part of the final system.
Project Matching
Final suitability depends on system series, opening size and project documentation.
