Real PA66 Insulation Strips
Our Thermal Break Aluminum Profiles come with PA66 fiberglass nylon insulation strips as standard. We do not use PVC strips. The standard wall thicknesses are 1.4mm, 1.8mm, and 2.0mm. We offer both single-cavity and multi-cavity designs. The insulation strip widths are available in 20A, 25A, and 30A. Surface finishes include powder coating, fluorocarbon coating, wood grain transfer, and electrostatic spraying.
We have been manufacturing aluminum profiles in Foshan for 15 years. We hold ISO9001 and CE export certifications. Every batch of insulation strips is tested for tensile strength and aging resistance before entering production.



Quality You Can Trust

Many customers ask about the quality of insulation strips. We explain clearly that PA66 strips cost several times more than PVC strips, but they also provide much longer service life. We choose PA66 because we do not want our customers to experience strip shrinkage or detachment after two or three years.
We support customized sections and colors based on your drawings. We provide complete OEM and ODM services. From section design and surface color to logo printing, we can customize products according to your requirements.
Our quality control starts with chemical testing of aluminum billets. We then check extrusion dimensions, and after finishing, we test color difference and coating thickness. Every production step is recorded. We inspect every piece before packing. We also welcome third-party inspections at our factory.

Wide Application and Strong Support
These Thermal Break Aluminum Profiles are mainly used in residential windows, project doors and windows, and energy-saving renovation projects for commercial buildings. Their thermal performance meets common building energy efficiency requirements. The multi-cavity design also improves overall rigidity and wind load resistance.
We provide free section selection advice and load calculations before purchase. During production, we send regular progress photos to keep you updated. After sales, we respond to any issues within 24 hours.
We support EXW Foshan factory delivery and FOB shipment from Foshan or Shenzhen port. Payment terms are 30% deposit, with the balance paid before loading. The spray-coated and fluorocarbon surfaces come with a 5-year warranty.
We are not the largest supplier, but we are very strict about insulation strip details. If you need a thermal break profile with stable performance and flexible structures, we can provide long-term cooperation.
