Window profiles have to maintain a stable connection between their interior and exterior aluminum sections while accommodating glazing, gaskets and hardware. The PA66 GF25 Window Thermal Break Strip from Jinxing provides the polyamide separation within this profile structure, with China factory production focused on accurate cross-sections, secure engagement and consistent assembly performance.
Unlike a general-purpose plastic insulation section, a window thermal break strip needs to fit the actual extrusion geometry.
The strip must correspond with:
· Frame or sash profile
· Thermal break cavity
· Groove dimensions
· Locking geometry
· Insertion direction
· Rolling conditions
This profile-to-profile fit is important for maintaining the designed separation after the aluminum sections are mechanically joined.
The strip uses PA66 nylon reinforced with 25% glass fiber. The reinforcement provides the rigidity needed during insertion and rolling while helping the profile maintain its shape after assembly.
The material also provides the low-conductivity barrier required between separated aluminum sections.
· Window-Specific Profile Fit — Developed for thermally broken aluminum window extrusions.
· PA66 GF25 Reinforcement — Provides rigidity and mechanical stability.
· Stable Cross-Section — Supports consistent engagement with the aluminum groove.
· Thermal Separation — Interrupts the continuous aluminum heat-transfer path.
· Customizable Geometry — Can be produced around different frame and sash profiles.
Both frame and sash sections can use thermal break profiles, but their cross-sections are not necessarily identical.
The required strip may vary according to the:
|
Window Profile Area |
Main Consideration |
|
Frame |
Cavity and mechanical engagement |
|
Sash |
Compact profile space and locking fit |
|
Glazing area |
Clearance around glazing and seals |
|
Corner sections |
Profile continuity and assembly |
|
Meeting section |
Matching geometry between adjoining profiles |
For this reason, the aluminum extrusion drawing is the preferred basis for confirming the strip size.
The PA66 GF25 Window Thermal Break Strip separates the interior and exterior aluminum sections, reducing direct heat conduction through the metal frame.
Its contribution works together with other window components, including glazing, gaskets, seals and the aluminum profile design. The strip itself is therefore one part of the complete window thermal performance.
During production, the strip needs to withstand insertion and mechanical rolling without excessive deformation or cracking.
Jinxing's PA66 GF25 material provides the required rigidity, while controlled extrusion helps maintain the profile dimensions needed for consistent engagement.
For new window profiles, strip geometry can be reviewed together with the aluminum extrusion before tooling and production.
PA66 GF25 Window Thermal Break Strip is suitable for compatible:
· Aluminum window frames
· Aluminum window sashes
· Sliding window profiles
· Casement window profiles
· Other thermally broken architectural window extrusions
Jinxing produces the strip through material blending, extrusion, cooling, shaping and precision cutting.
Incoming materials can be checked for melt flow index, glass-fiber content and moisture. During extrusion, process conditions are controlled to maintain profile consistency, while samples are inspected for dimensions and surface defects.
Finished profiles undergo appearance and dimensional inspection before shipment.
It is a glass-fiber-reinforced polyamide thermal break profile designed for thermally separated aluminum window systems.
The 25% glass-fiber reinforcement improves the rigidity and mechanical stability required during profile insertion and assembly.
Not necessarily. Frame and sash sections can have different cavities and locking geometries, so the strip should be selected according to the actual extrusion.
Yes. It separates the aluminum sections and interrupts the direct metal heat-transfer path, contributing to the thermal performance of the window system.
Yes. Jinxing can develop customized sections according to aluminum window profile drawings or physical samples.
The aluminum profile drawing, required strip dimensions, application type and assembly method are useful for confirming the correct profile.
