Thermally broken vs Non thermally broken aluminium frames

Thermally broken and non-thermally broken aluminum frames are two types of construction methods used in aluminum windows and doors. Let's compare them:

1. Thermal Performance:
   
   
   • Thermally broken frames: These frames have a thermal barrier, typically made of a non-conductive material like polyamide, inserted between the interior and exterior aluminum sections. This barrier helps reduce heat transfer and improves insulation, resulting in better energy efficiency and reduced heat loss or gain.
     
   • Non-thermally broken frames: These frames lack a thermal barrier, allowing heat to easily transfer between the interior and exterior surfaces. This can result in more significant heat loss or gain, leading to reduced energy efficiency.
     
2. Condensation and Moisture:
   
   
   • Thermally broken frames: The presence of a thermal barrier helps minimize condensation on the frame's interior surface by reducing the temperature difference between the inside and outside. This can help prevent moisture-related issues such as mold or mildew growth.
     
   • Non-thermally broken frames: Without a thermal barrier, these frames are more prone to condensation, especially in areas with significant temperature differences between the inside and outside. This can increase the risk of moisture-related problems if not properly managed.
     
3. Structural Strength:
   
   
   • Thermally broken frames: The addition of a thermal barrier can enhance the structural strength of the frame by providing better load-bearing capabilities and rigidity.
     
   • Non-thermally broken frames: While still structurally sound, non-thermally broken frames may have slightly lower load-bearing capacities compared to their thermally broken counterparts.
     
4. Sound Insulation:
   
   
   • Thermally broken frames: The thermal barrier in thermally broken frames can also contribute to improved sound insulation, reducing the transmission of external noise into the interior space.
     
   • Non-thermally broken frames: Without a thermal barrier, non-thermally broken frames may provide slightly less sound insulation, allowing more external noise to penetrate the space.
     

It's important to note that both thermally broken and non-thermally broken aluminum frames have their advantages and considerations. The choice between the two depends on factors such as climate, energy efficiency requirements, budget, and specific project needs.
