Product Features

Thermal Insulation: Thanks to its polyamide composition, the CF34 strip minimizes thermal bridging in metal frame systems, improving overall building energy performance.

Mechanical Strength: The nylon material offers strong tensile and flexural strength, ensuring structural stability in aluminum windows, doors, and curtain walls.

Customizable Dimensions: Width, thickness, and length can be tailored to meet project-specific needs, making CF34 flexible for various frame profiles.

Eco-Friendly & Safe: BGM-CF34 is eco-friendly and free from harmful substances, with CE and ISO 9001 certifications backing its reliability.

Logo Personalization: Customers can request custom logos, helping with brand identification or specification requirements.

Long Warranty: Backed by a 5-year (or more) warranty, this thermal barrier strip provides reassurance about quality and performance over time.

What structural advantages do nylon-based thermal barrier strips offer beyond thermal insulation? 

Nylon-based thermal barrier strips offer important structural advantages beyond just reducing heat transfer. Because they are typically engineered from reinforced polyamide (nylon) with glass fiber, they combine excellent mechanical strength and dimensional stability with thermal insulation properties, allowing them to support aluminum profiles under load without deformation or failure. This means assemblies like curtain walls, windows, and door frames can maintain structural integrity while still benefiting from reduced thermal bridging.

In practice, this results in better resistance to wind loads, repeated movement, and environmental stresses compared with non-reinforced materials. The similar coefficient of thermal expansion between nylon and aluminum helps prevent internal stresses during temperature cycling, avoiding cracking or separation at the interface.

Additionally, nylon’s stability under heat and moisture gives it an edge over many alternative materials. It resists creep and long-term deformation, helping maintain tight seals and dimensional precision over time. In some cases, nylon thermal breaks also contribute to improved acoustic insulation and weather resistance, enhancing overall building performance and occupant comfort.

Product Capacity

Our production facility in Zhejiang, China, is fully equipped to manufacture BGM-CF34 at scale while maintaining tight quality controls. As part of our broad offering of Thermal Barrier Strips, we support both standard and customized orders — whether for small architectural runs or large building projects. We maintain stable capacity and flexible production planning, enabling timely delivery even for tailored widths, thicknesses, or packaging requirements.

Product Packaging

Our products are packaged in waterproof bags. During each vehicle loading, random weight checks are conducted on every package. Typically, pallets are placed underneath to support the weight, facilitating subsequent packaging and preventing bag damage from rough handling during transport. Goods on each pallet are wrapped in stretch film to minimize moisture exposure during transit.
