Designed specifically for aluminum window profiles, the PA66 GF25 Aluminum Window Thermal Break Strip from Jinxing combines reinforced polyamide material with profile-specific extrusion accuracy. As a China manufacturer and factory, Jinxing produces thermal break strips that match different aluminum window structures, helping maintain the separation between interior and exterior aluminum sections while supporting the mechanical requirements of the finished window system.
Aluminum windows require thermal separation without losing the strength and rigidity of the metal frame. The thermal break strip works as the insulating connection between two aluminum sections, reducing the direct heat-transfer path while keeping the profile mechanically connected.
The strip design needs to match the actual window extrusion, including:
· Frame and sash structure
· Thermal break cavity
· Locking area
· Profile dimensions
· Assembly process
The strip is made from PA66 reinforced with 25% glass fiber. This material combination provides:
· Improved Rigidity — Supports stable installation within aluminum profiles.
· Dimensional Stability — Helps maintain the designed profile shape.
· Mechanical Strength — Suitable for insertion and rolling processes.
· Thermal Separation — Creates a lower-conductivity barrier between aluminum sections.
· Designed for Aluminum Windows — Matches the requirements of thermally broken window profiles.
· PA66 GF25 Reinforcement — Provides strength and stability during profile processing.
· Accurate Profile Dimensions — Supports consistent engagement with aluminum grooves.
· Stable Long-Term Performance — Helps maintain the integrity of the thermal break assembly.
· Custom Section Availability — Can be developed according to different window profiles.
Different aluminum window systems may require different thermal break strip designs.

PA66 GF25 Aluminum Window Thermal Break Strip is suitable for:
· Aluminum casement windows
· Aluminum sliding windows
· Tilt and turn windows
· Energy-efficient window systems
· Customized thermally broken aluminum profiles
Jinxing produces the strip through:
Material preparation → Extrusion molding → Cooling and shaping → Precision cutting
During production, extrusion parameters such as temperature, pulling speed and cooling conditions are controlled to maintain profile consistency.
Incoming PA66 and glass fiber materials can be checked for moisture, melt flow index and glass-fiber content. Finished strips are inspected for dimensions and surface quality before shipment.
Window systems often use different aluminum extrusion structures. Jinxing can customize thermal break strips according to profile drawings or samples.
Customization includes:
· Cross-sectional design
· Width and thickness
· Locking details
· Color
· Length
· Packaging
· Laser coding
The development process can include tooling, trial extrusion, dimension confirmation and mass production.
It is a glass-fiber-reinforced polyamide profile installed between aluminum window sections to provide thermal separation.
PA66 GF25 combines thermal insulation properties with the rigidity and dimensional stability required for aluminum profile assembly.
Yes, but the cross-section and dimensions should match the specific aluminum extrusion structure.
They are commonly used in casement windows, sliding windows and other thermally broken aluminum window systems.
Yes. Jinxing can develop customized sections based on aluminum profile drawings or samples.
The aluminum profile drawing, cavity dimensions, required section and assembly method are needed to confirm the suitable thermal break strip.
