Aluminum Thermal Break for Window Door curtain wall Profile

Key Functions of a Thermal Break in Aluminum:

1. Reduces Heat Transfer – Aluminum is highly conductive, allowing heat/cold to pass easily. A thermal break (often made of polyamide or similar material) interrupts this flow, improving energy efficiency.

2. Prevents Condensation – By minimizing temperature differences between interior and exterior surfaces, thermal breaks reduce condensation buildup.

3. Enhances Energy Efficiency – Helps maintain indoor temperatures, reducing HVAC costs (important in green building standards like Passivhaus or LEED).

4. Structural Integrity – The thermal break material must maintain strength while providing insulation, ensuring durability.

5. Noise Reduction – Can also help dampen sound transmission.

Common Applications:

• Windows & Doors – Thermal breaks help meet energy codes (e.g., U-factor requirements).

• Curtain Walls & Facades – Used in commercial buildings to improve thermal performance.

• Industrial & Cold Storage – Prevents thermal bridging in refrigerated spaces.

Types of Thermal Breaks:

• Polyamide Strips – Most common, with good insulation and mechanical strength.

• Foam Insulation – Sometimes used for additional thermal resistance.

• Hybrid Systems – Combining multiple materials for better performance.
