Designed around your project
A thermal-break aluminium frame uses a less conductive separation between parts of the metal profile. This addresses heat transfer through the frame, while the glazing and installation remain equally important parts of the assembly.
Thermal break is a construction description, not a universal energy rating. Compare proposed systems using the relevant whole-window evidence, the glazing specification and the dimensions used in the supporting assessment.
Before sourcing thermal-break windows from China, share your destination, climate context and the required design criteria. The project team can then review an appropriate combination of frame, glass, opening style and installation detail.
From brief to specification
A starting point for selection. Final dimensions and configurations are confirmed through the quotation and drawing review.
| Decision | What to discuss |
|---|---|
| Frame construction | Aluminium profiles with a thermal separation |
| System selection | Review against project dimensions and design criteria |
| Glazing | Coordinate glass build-up with the required performance |
| Condensation | Assess climate, humidity and installation conditions |
| Evidence | Verify applicable reports for the proposed configuration |
Performance, compliance and suitability must be confirmed for the selected assembly and destination. No generic rating is implied.
No. Frame geometry, the thermal separator, glass, opening type and installation all contribute to the result. Compare like-for-like assemblies and relevant documentation.
Condensation also depends on indoor humidity, ventilation, surface temperatures and installation. A thermal break alone cannot guarantee that condensation will never occur.
Use the requirements of the building and destination as the starting point. Share the performance criteria and have the proposed assembly reviewed by your project team.
