Heat Insulation Strips For Windows

Product Features

Excellent Thermal Insulation: The polyamide base material offers low thermal conductivity, significantly reducing heat transfer in metal frame systems and improving the building’s overall energy performance.

High Mechanical Strength: With strong tensile and flexural properties, the HK35 Heat Insulation Strips maintains structural integrity in demanding façade applications, resisting deformation under load.

Adaptable Dimensions: The strip can be customized in width, thickness, and length to match specific aluminum profile designs, ensuring compatibility with various curtain‐wall, door, and window systems.

Eco-Conscious Material: Made from environmentally safe polymers, the HK35 Heat Insulation Strips supports green building practices; the production is backed by quality management certifications such as ISO 9001 (per BGM’s general product line).

Brand Customization: Customers can request tailored logos or markings on the strip for brand recognition, easier specification control, or production traceability.

Warranty Assurance: The product comes with a multi-year warranty (e.g., five years or more), reflecting BGM’s confidence in its durability and long-term thermal performance.

What Engineering Challenges Do Thermal Barrier Strips Solve in Curtain Wall and Window Systems?

Thermal barrier strips such as the BGM-I30 Heat Insulation Strips address several critical engineering challenges in curtain wall and window systems by interrupting the direct heat conduction path through aluminum frames. Without a thermal break, aluminum aggressively conducts heat from outside to inside (and vice versa), causing significant energy loss and higher heating or cooling loads. A properly engineered nylon thermal insulation strip inserted between interior and exterior profiles breaks this thermal bridge, helping maintain interior comfort and reduce overall energy consumption.

Another major challenge is condensation and moisture control . In unbroken metal frames, cold exterior temperatures can cool interior surfaces below the dew point, leading to water condensation. Over time, this can degrade adjoining materials, promote mold growth, and impair indoor air quality. Thermal barrier strips raise the surface temperature of internal frame components, significantly reducing the likelihood of condensation and its associated problems.

Structural performance under environmental stress is also a concern. Changes in temperature can cause differential expansion between metal components, compromising seal integrity and energy performance. By using engineered nylon materials with compatible thermal expansion behavior and high mechanical stability, products like the BGM-I30 help maintain both insulation and structural reliability throughout temperature fluctuations.

Product Capacity

BGM’s manufacturing facility in Zhejiang is fully equipped with advanced extrusion lines and quality control systems, enabling stable and scalable production of the HK35 Heat Insulation Strips. Whether the order is for standard dimensions or custom variants, the plant can accommodate both small runs for custom architectural features and large-volume orders for major facade projects. Each batch undergoes rigorous inspections, including dimensional verification, mechanical tests, and surface finish checks, to ensure consistency and reliability. This flexible capacity planning helps BGM meet varied lead-time requirements without compromising on quality.

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.
