THERMAL BREAK FRAMES
Thermal-Break vs Non-Thermal-Break Aluminum Frames
Thermal-break aluminum frames include a lower-conductivity separation between metal sections to reduce heat transfer through the frame. Non-thermal-break frames do not use that same separation.
For importers, distributors, contractors, project buyers and homeowners planning custom aluminum windows.
FAQ
Before we begin.
A few things to know before you start your window and door inquiry.
Does double glazing make a frame thermal-break?
No. Double glazing describes the glass arrangement, while thermal-break describes the frame construction. A non-thermal-break frame can be shown with double glazing in the catalogue. Read both fields when comparing the entries.
Is a thermal-break frame the same as a certified energy rating?
No. It describes a construction feature, not a certification status or a particular whole-product result. A rating must be tied to the relevant document and configuration.
Can I compare glass Ug with whole-window Uw?
They describe different parts of the product assessment: glass alone and the complete window respectively. Identify what each value measures before using it in a comparison, and check the units and supporting method.
Does thermal-break construction guarantee that condensation will never occur?
Condensation depends on the conditions, complete product and installation; thermal-break construction alone cannot guarantee that it will never occur. Do not treat a frame description as proof that condensation is impossible in every use environment.
Is non-thermal-break construction suitable for my project?
Start with the requirements specified for your project and compare the proposed complete product against them. The catalogue description alone cannot establish suitability for every climate or building use.
Which ENGGIA ranges include both frame types?
The initial catalogue includes both types within awning windows, sliding windows, sliding doors and bifold doors. The listed casement entries are thermal-break. See the relevant category table for the specific model and glass configuration.
