PA66GF25 Window Insulation Bars

He coefficient of thermal expansion (CTE) of Noise Reduction Thermal Barrier Strips is remarkably close to that of aluminum alloy (PA66 GF25 ~ 3.0 × 10⁻⁵ /K vs. aluminum alloy ~ 2.3 × 10⁻⁵ /K). This compatibility is absolutely critical, as it ensures synchronous thermal expansion and contraction between the thermal barrier and adjoining aluminum profiles during temperature fluctuations. Such dimensional harmony effectively prevents structural deformation, cracking, or seal failure caused by excessive differential expansion.Additionally, PA66 GF25 demonstrates excellent dimensional stability, resisting significant size variations due to moisture absorption or temperature changes.

Product Introduction

PA66GF25 Window Insulation Bars are engineered to offer superior performance and longevity in window and door insulation applications. These bars are designed with an impact-resistant PA66GF25 window insulation bars structure, ensuring they maintain their integrity even under mechanical stress. Their corrosion-resistant PA66GF25 window insulation bars properties make them ideal for use in harsh environments, while the high-tensile PA66GF25 window insulation bars propertiesstrength ensures they can withstand heavy loads without deformation. Abrasion-resistant PA66GF25 window insulation bars and non-toxic PA66GF25 window insulation bars, these bars provide a safe and durable solution for modern construction projects.

One of the standout features of these PA66GF25 window insulation bars is their excellent compatibility with aluminum profiles, thanks to the close coefficient of thermal expansion (CTE). This ensures that the bars expand and contract at the same rate as the surrounding materials, preventing structural deformation, cracking, or seal failure caused by temperature fluctuations. Additionally, the eco-friendly PA66GF25 window insulation bars composition of the PA66GF25 provides a sustainable solution, while the efficient PA66GF25 window insulation bars insulation properties of these bars contribute to enhanced energy performance in any building project.

Thermal Break Polyamide Strip in Plastic Extruded Profile enable Passive House windows to achieve ultra-low U-values of ≤0.8 W/m²K.
