THERMAL-BREAK ALUMINUM WINDOWS
Thermal-break aluminum windows need whole-window evidence.
Compare documented casement and sliding routes without treating a thermal barrier as proof of completed-window performance. Frame, glass, spacer, seals, size and installation must be reviewed together.

PROJECT SELECTION
Choose from the opening schedule—not a material slogan.
Use the same project basis for every route. Final system, size, glass, hardware, finish and performance are confirmed only after authorised review.
- Whole-window thermal target and calculation basis
- Opening type, dimensions and exposed elevation
- Glass build-up, spacer and solar-control requirement
- Air, water and structural evidence for the proposed configuration
- Installation interface, perimeter sealing and drainage

BUYER QUESTIONS
Short answers before detailed review.
Does a thermal break guarantee a specific U-value?
No. A whole-window value depends on the complete frame, glass, spacer, seals, size and calculation or test basis.
Can one test report cover every window size?
Not automatically. Check the tested specimen, method, opening type and differences from the proposed unit.
Should hot-climate projects review SHGC as well as U-value?
Yes. Conductive heat transfer and solar gain are separate design questions that must be coordinated with the glazing route.
