Thermally broken aluminum profiles, also known as insulated aluminum alloy profiles, thermally broken aluminum alloy profiles, thermally broken profiles, and thermally broken aluminum-plastic composite profiles, offer superior performance compared to ordinary aluminum alloy profiles. Advantages include waterproofing, burglarproofing, fire resistance, and condensation prevention.
The "bridge" in "thermally broken aluminum" refers to a thermal bridge in materials science, while "broken" indicates the action of breaking the thermal bridge.
Specifically, because aluminum alloy is a metal with relatively high thermal conductivity, it can act as a "bridge" for heat transfer when there is a significant temperature difference between indoors and outdoors. Windows and doors made from such materials suffer from poor thermal insulation. Thermally broken aluminum, however, breaks the aluminum alloy in the middle and connects the broken sections with a rigid plastic material. Since plastic has significantly lower thermal conductivity than metal, heat is less likely to pass through the entire material, thus improving its thermal insulation performance. This is the origin of the name "thermally broken aluminum (alloy)."
