Enhanced Mechanical Stability: Engineered with strong tensile and flexural properties, KTU30 maintains frame rigidity even in large curtain wall units and high-rise facade systems.

Customizable Design: Width, thickness, and length can be tailored to meet project specifications, ensuring seamless integration with multiple aluminum profile geometries.

Eco-Friendly Assurance: Made from environmentally safe materials and supported by CE and ISO9001 certifications, the product aligns with modern green building requirements.

Branding Options: Custom logo printing is available, enabling better identification, traceability, and professional presentation for system manufacturers.

Long-Term Warranty: KTU30 comes with a warranty of five years or more, reflecting its long-lasting performance and dependable quality.

When installing polyamide thermal barrier strips proper preparation and execution are critical to ensure they perform as intended in aluminum profile systems. These strips must fit precisely within the aluminum channels to create an effective thermal break that reduces heat transfer and enhances energy efficiency. To achieve a secure and functional installation, several practical considerations should be addressed. 

What practical installation considerations should be addressed for thermal barrier strips in aluminum systems?

First,  frame handling and preparation are essential. Components should be handled carefully to avoid damaging the polyamide strips or aluminum channels. Before installation, verify all profiles and dimensions against project specifications and drawings, and confirm that grooves or pockets in the aluminum extrusions are designed to accept the thermal breaks without gaps. 

During mounting, proper fastening techniques help maintain both structural integrity and insulation performance. Fasteners should be corrosion‑resistant and positioned to prevent thermal bridging, and drilled holes should be slightly larger than the fastener diameter to avoid cracking or compressing the polyamide strips. 

Attention to sealant and glazing orientation is also important. Correct application of sealants around critical joints and sub‑sills prevents air and water infiltration, while correct glazing alignment ensures that the thermal break remains unobstructed. 

Finally, factors like shimming, alignment, and environmental conditions influence long‑term performance. Non‑compressible shims and controlled fastening prevent deformation of the frame or strip. Installation in dry conditions and allowances for thermal movement help maintain effectiveness over time, especially since polyamide and aluminum have similar but not identical expansion rates.

Product Capacity

Our Zhejiang-based production center is equipped with advanced extrusion and machining technology, enabling stable mass production of the BGM-KTU30 Thermal Barrier Strip. We support a wide range of order sizes—from standard product batches to fully customized specifications—without sacrificing manufacturing precision. Strict quality checks are applied throughout each stage of production to ensure uniformity, mechanical strength, and dimensional accuracy. Flexible capacity planning allows us to meet project deadlines and accommodate special customization requirements efficiently.

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.
