How does the choice of material affect thermal insulation performance?

The choice of PA66 nylon as the base material for thermal break strips significantly influences thermal insulation performance in aluminum building systems. PA66 inherently has low thermal conductivity , meaning it does not easily transfer heat compared to metals like aluminum. When placed between interior and exterior aluminum profiles, PA66 creates a continuous insulating barrier that reduces thermal bridging and limits heat flow , helping maintain more stable indoor temperatures and improving overall energy efficiency.

In many high-performance thermal break strips, PA66 is reinforced with glass fiber (e.g., PA66 GF25). This reinforcement not only enhances mechanical strength and stiffness but also improves dimensional stability across temperature variations, ensuring the insulating gap remains consistent over time. Because PA66 has a relatively low coefficient of thermal expansion close to that of aluminum, stresses at the metal-to-plastic interface are minimized during temperature changes, which contributes to long-term performance in both hot and cold climates.

Overall, the use of PA66 nylon enables thermal break strips to combine effective heat insulation with structural reliability, making them suitable for application in windows, doors, curtain walls, and other architectural systems where energy performance and durability are essential.

Product Packaging

Our products are packaged in waterproof bags. During each vehicle loading, random weight checks are conducted on every package. Typically, pallets are placed underneath to support the weight, facilitating subsequent packaging and preventing bag damage from rough handling during transport. Goods on each pallet are wrapped in stretch film to minimize moisture exposure during transit.
