The PA66 GF25 Fire Resistant Thermal Break Strip from Jinxing is designed for aluminum systems requiring a reinforced polyamide thermal barrier with added fire-resistance requirements. As a China manufacturer and supplier, Jinxing produces the strip according to the aluminum profile cavity and assembly method, balancing thermal separation, mechanical stability and profile accuracy.
PA66 provides the base material for the thermal barrier, while 25% glass fiber increases rigidity and dimensional stability. For fire-resistant applications, the material formulation can be selected according to the required project specification.
The strip needs to maintain its intended shape and mechanical connection while also meeting the fire-related requirements of the application. The exact fire-performance level should be confirmed according to the applicable test method or project standard.
The polyamide section interrupts the direct connection between interior and exterior aluminum parts, reducing the metal heat-transfer path.
The reinforced profile is designed to withstand insertion, rolling and the mechanical loads generated after the aluminum sections are joined.
· Fire-Resistant Material Option — Developed for aluminum systems with additional fire-performance requirements.
· PA66 GF25 Reinforcement — Provides rigidity and mechanical stability.
· Stable Profile Geometry — Supports accurate engagement with aluminum cavities.
· Thermal Separation — Creates a lower-conductivity barrier between aluminum sections.
· Customizable Section Design — Can be adapted to different aluminum profile structures.
Suitable for thermally broken window profiles where fire-related material requirements are part of the system specification.
Used in door systems requiring both thermal separation and a reinforced polyamide profile.
Applicable to curtain wall framing where the thermal break component must be considered alongside the overall façade fire-performance design.
PA66 GF25 Fire Resistant Thermal Break Strips should not be selected only by the product name. Buyers should confirm the required:
· Fire-performance classification or test method
· Aluminum profile design
· Strip dimensions
· Mechanical engagement
· Installation method
This allows the material and profile to be evaluated against the actual application.
The aluminum extrusion determines the required strip geometry.

Jinxing can review drawings or physical samples when a standard section does not match the aluminum profile.
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, temperature, pulling speed and cooling conditions are controlled to maintain profile consistency.
Finished strips are inspected for appearance and dimensions before shipment, while applicable mechanical, thermal aging, water resistance and fire-related properties can be evaluated according to the required specification.
Jinxing manages the material preparation and extrusion process, helping maintain consistent profile dimensions and reinforcement characteristics.
PA66 GF25 Fire Resistant Thermal Break Strips can be developed around the actual aluminum extrusion instead of relying on one fixed cross-section.
Jinxing can assist with profile slot design, strip insertion and roll-forming conditions for projects requiring a specific thermal break profile.
Customization can include:
· Cross-sectional geometry
· Width and thickness
· Locking details
· Color
· Cut length
· Packaging
· Laser coding
The development process can proceed from profile drawing → tooling → trial extrusion → dimension confirmation → mass production.
Standard straight strips are supplied at 6 m per piece. Coiled supply can be arranged for suitable specifications, with cut-to-length processing available for specific aluminum profile requirements.
It is a PA66 thermal break profile reinforced with 25% glass fiber and developed for aluminum systems with additional fire-resistance requirements.
GF25 means the PA66 material contains 25% glass-fiber reinforcement.
No. The thermal break strip is one component of the system. Overall fire performance depends on the complete design, materials, glazing, seals and applicable testing requirements.
The required material grade and fire-performance level should be confirmed according to the project specification before production.
Yes. Jinxing can develop customized sections according to aluminum profile drawings or physical samples.
It can be used in compatible thermally broken aluminum windows, doors, curtain walls and other architectural aluminum systems.
