For years, in the foreign trade of building materials, Thermal Break Aluminum Profile has been a main component for overseas window and door manufacturers and real estate projects, especially in Europe, south America, the Middle East, and Southeast Asia and Africa where energy efficiency requirements are high. It's practically a standard component in high-end windows and doors. We only produce truly compliant products. All processes, parameters, and performance are tested in our factory and come with official testing reports. We never exaggerate or misrepresent, nor do we use inferior composite processes. Our products pass export standard and project acceptance without issue, giving our overseas customers complete peace of mind.
The core of this Thermal Break Aluminum Profile is made from 6063-T5 virgin aluminum rods through hot extrusion. It uses an industry-standard through-strip thermal break structure, with a PA66 GF25 fiberglass reinforced thermal break strip embedded in the center. This is not a brittle ordinary plastic strip; it's crucial for ensuring excellent insulation and long-term durability. The entire production process adheres to international profile standards GB/T 5237. It contains no harmful additives and is suitable for use in residential, commercial, and public buildings.
The profile wall thickness is divided into two categories: 1.4mm is standard for residential doors and windows, while 1.8mm and above are used for high-rise buildings and coastal projects requiring high wind pressure resistance, ensuring strength fully complies with overseas building codes. Lengths can be precisely cut from 1–6.5m to order, with dimensional tolerances controlled within the range that overseas door and window equipment can directly process. Milling, corner assembly, and splicing are all smooth, requiring no additional adjustments to processing parameters.
Surface treatments are exclusively for export-grade durable models: anodizing, powder coating, fluorocarbon coating, and wood grain transfer printing, with colors covering the full RAL color chart. The outdoor version features a fluorocarbon coating, resistant to UV rays and salt spray, and will not fade or chalk for over a decade, even under harsh conditions like seaside sun and Middle Eastern sandstorms. The indoor version uses powder coating or wood grain finishes, offering a smooth feel and easy maintenance, and complements various interior design styles.
Compared to ordinary aluminum alloy profiles, its practical advantages are obvious: the thermal break strip has extremely low thermal conductivity, structurally cutting off heat conduction. It blocks high outdoor temperatures in summer and reduces indoor heat loss in winter, effectively lowering building energy consumption, matching the material selection standards for passive houses and low-energy residences overseas. The multi-cavity design with dedicated sealing strip grooves ensures airtightness and watertightness, preventing water leakage in heavy rain and dust ingress in strong winds. Its sound insulation also meets the needs of noisy areas such as street frontage and airport surroundings.
Thermal Break Aluminum Profile offers sufficient overall rigidity and meets wind pressure resistance standards, ensuring it will not deform or sag in high-rise residential buildings or windy coastal areas, with a normal service life exceeding 20 years. Aluminum alloy itself is rust-free, and the thermal break strips withstand temperatures ranging from -40℃ to 120℃, ensuring stable use in most climate zones worldwide. Furthermore, aluminum is 100% recyclable, highlighting its environmentally friendly properties, making it a preferred choice for overseas government projects and large-scale real estate developments.
The production process strictly adheres to export quality control.
Each batch undergoes mechanical performance testing, shear strength testing, thermal cycling testing, and salt spray testing, with verifiable test reports.
