Product Introduction

High-performance nylon thermal barriers are designed to create an effective "thermal break" when integrated into aluminum profiles, halting heat transfer along metal sections. These durable high-performance nylon thermal barriers are engineered with exceptional mechanical properties and thermal expansion coefficients that align with aluminum alloys, ensuring reliable, long-lasting performance.

Our UV-resistant high-performance nylon thermal barriers offer superior protection against sun exposure, preventing degradation and maintaining structural integrity over time. In addition, the waterproof high-performance nylon thermal barriers are ideal for applications where moisture resistance is essential, such as windows and doors exposed to external environments.

These barriers also boast excellent chemical-resistant high-performance nylon thermal barriers that withstand harsh chemicals, making them suitable for industrial and outdoor applications. Engineered to endure mechanical stress, the impact-resistant high-performance nylon thermal barriers are perfect for environments where durability is critical. Furthermore, the high-temperature high-performance nylon thermal barriers offer superior resistance to extreme heat, ensuring long-term insulation even in challenging conditions.

As a result of these advanced features, PA66GF25 thermal insulation profiles have become the dominant choice for high-performance windows, doors, and curtain walls in modern construction, offering both environmental sustainability and exceptional performance in energy-efficient designs.

Our advanced production lines significantly enhance the manufacturing efficiency of Heat Break Strip for Aluminum Windows.

Product Advantage

Thermal Break Strips for Aluminum Windows are precision-joined with aluminum profiles through roll-forming technology, ensuring structural integrity of windows and doors under wind loads, gravitational forces, and other mechanical stresses.
PA66GF25 Window Insulation Bars exhibit a thermal expansion coefficient (~25×10⁻⁶/°C) closely matched to aluminum alloy (~23.6×10⁻⁶/°C), enabling synchronous dimensional movement during temperature fluctuations.
The precisely matched thermal expansion characteristics between Weatherproof Thermal Break Strips and aluminum profiles effectively minimize internal stresses induced by thermal cycling, preventing profile cracking or deformation - making this system particularly suitable for regions with extreme temperature variations.
Thermal Break Strips for Curtain Walls are strategically positioned to work in tandem with sealing gaskets (e.g., EPDM rubber seals), creating a synergistic sealing system that enhances overall window airtightness.
PA66GF25 Low Thermal Conductivity Strips possess inherent sound-damping properties that effectively attenuate acoustic wave transmission through aluminum profiles.

Our PA66 GF25 thermal break strips fully comply with China's GB/T 23615.1-2017 national standard for architectural thermal barriers.
