Modern thermal design in construction increasingly relies on materials that combine exceptional insulation performance with structural durability. Our industrial-grade Thermal Break Strips for Aluminum Windows are engineered to meet these demanding standards, serving as a critical component in achieving energy-efficient building designs. Crafted from eco-friendly Thermal Break Strips for Aluminum Windows, these products leverage the superior properties of PA66GF25 polyamide. The high-strength Thermal Break Strips for Aluminum Windows incorporate 25% glass fiber reinforcement, enhancing their mechanical resilience while providing outstanding thermal insulation capabilities. These precision-engineered Thermal Break Strips for Aluminum Windows are ideal for insulating critical junctions such as window frames and wall connections, where traditional materials often fall short in preventing heat transfer. Our durable Thermal Break Strips for Aluminum Windows are designed to withstand the mechanical stresses of construction environments, ensuring long-term performance. For projects requiring specific measurements, we offer custom-sized Thermal Break Strips for Aluminum Windows that guarantee perfect fit and optimal thermal performance. By investing in our energy-efficient Thermal Break Strips, you are adopting a solution that promotes sustainable building practices, reduces energy costs, and improves overall building performance.
Glass-Fiber Reinforced PA66 Thermal Profiles are precision-manufactured with ±0.1mm tolerance, complying with ISO 527 tensile tests for consistent quality.
Thermal break aluminum profile insulation strips (Aluminum-wood composite doors and windows insulation strips) is made of glass fiber reinforced nylon (PA66+25%GF), with tensile strength ≥150MPa and flexural strength ≥200MPa. It withstands temperatures from -40℃ to 120℃, maintaining structural stability in outdoor doors/windows and extreme climates, reducing fracture risks caused by thermal expansion.
As a core material for building energy efficiency, Energy-saving doors and windows insulation strip (High-end doors and windows insulation strip PA66GF25) has a thermal conductivity of only 0.3W/(m·K), much lower than PVC (1.0W/(m·K)) and ordinary nylon (0.5W/(m·K)). It effectively blocks heat transfer in aluminum profiles, reducing building energy consumption by 15%-20% and supporting green building certifications (e.g., GB/T 50378).
With added UV and weather-resistant agents, Insulation strip for building curtain walls (Aluminum alloy thermal insulation profile PA66GF25) passes 1000-hour salt spray test (ISO 9227) and 5000-hour artificial aging test (GB/T 1865). No cracking or discoloration occurs after outdoor use, retaining over 90% performance after 20 years, reducing frequent replacement costs.
Manufactured via high-precision injection molding, High-temperature resistant insulation strip PA66GF25 (High-insulation insulation strip) has a tolerance of ±0.1mm, perfectly fitting thermal break aluminum profiles (e.g., 14.8mm/20mm standard grooves). It prevents air leakage and seal failure caused by dimensional deviations, meeting the needs of high-end system doors/windows customization.
The product is certified by ROHS (lead/cadmium-free), UL94 V-0 (flame retardant), and EU EN 14024 (thermal performance). It contains no halogens or harmful volatiles, ensuring odor-free installation, compliance with European/American safety standards (e.g., AAMA 810), and smooth export to meet GB/T 23615 (Energy-saving insulation strip PA66GF25).
Windows equipped with Thermal Break Strips for Aluminum Windows achieve a thermal conductivity of 0.25W/m·K, boosting energy efficiency by 60%.
