PA66 GF25 Large Section Thermal Break Strip is developed for aluminum profiles with wider thermal break cavities and larger section dimensions. Jinxing manufactures the PA66 GF25 profile in China, combining 25% glass-fiber reinforcement with controlled extrusion to provide stable thermal separation, rigidity and reliable mechanical engagement in large window, door and curtain wall systems.
Large aluminum sections place greater demands on the thermal break component because the strip must maintain its shape and connection across a wider profile structure. Jinxing, a China manufacturer and supplier, produces the PA66 GF25 Large Section Thermal Break Strip according to the actual extrusion, allowing the section width, thickness and engagement areas to correspond with the aluminum profile.
Built for Large Aluminum Sections
Wider Thermal Break Geometry
Large-section aluminum profiles often require a wider or deeper thermal break structure than conventional window sections. The strip needs to provide sufficient separation between the aluminum components without compromising the mechanical connection.
For this reason, the overall section should be evaluated together with the aluminum extrusion rather than selected by application name alone.
Profile Stability Along the Section
A PA66 GF25 Large Section Thermal Break Strip needs consistent dimensions across its full length. Variations in width, thickness or locking areas can affect insertion, rolling and the final connection between the aluminum sections.
Jinxing controls extrusion temperature, pulling speed and cooling conditions to maintain the required profile geometry.
PA66 GF25 Reinforcement
Mechanical Rigidity
The 25% glass-fiber reinforcement gives the PA66 profile the rigidity required for handling, insertion and mechanical rolling.
Dimensional Retention
The reinforced material helps the strip maintain its designed cross-section under the mechanical and temperature conditions encountered in the finished aluminum profile.
Product Application
Large Windows and Doors
Suitable for aluminum window and door systems using wider thermal break cavities or deeper profile sections.
Curtain Wall Mullions and Transoms
Applicable to larger façade profiles where the thermal break needs to remain stable within long aluminum sections.
Customized Architectural Profiles
Suitable for special aluminum extrusions where a conventional thermal break dimension does not provide the required section.
What Determines the Correct Size?
The size of a large-section thermal break strip depends on the actual aluminum extrusion.
Profile Factor
Why It Matters
Break width
Determines the required strip width
Profile depth
Defines the available installation space
Wall geometry
Affects strip positioning
Locking areas
Determines mechanical engagement
Assembly method
Influences insertion and rolling
Manufacturing for Large Profiles
Jinxing produces PA66 GF25 Large Section Thermal Break Strips through material preparation, extrusion, cooling, shaping and precision cutting.
For larger sections, maintaining stable profile geometry during cooling and shaping is particularly important. Production samples are checked for cross-sectional dimensions and surface condition, while finished profiles undergo appearance and dimensional inspection.
Why Choose Jinxing
Section Development
Jinxing can develop large-section thermal break profiles according to aluminum extrusion drawings or physical samples instead of limiting production to fixed standard dimensions.
Controlled Extrusion
From material preparation to cooling and cutting, the production process is managed around the required profile geometry and dimensional consistency.
Practical Assembly Support
For profile manufacturers, Jinxing can provide technical support related to strip insertion, slot design, roll-forming conditions and problems such as cracking or insufficient mechanical engagement.
Customized Large-Section Profiles
Customization can include:
· Overall width and thickness
· Profile depth
· Locking geometry
· Special cross-sections
· Color
· Cut length
· Packaging
· Laser coding
New profiles can proceed from aluminum profile drawing → section review → tooling → trial extrusion → dimensional confirmation → mass production.
Supply Options
Standard straight strips are supplied at 6 m per piece. Coiled supply can be arranged for suitable specifications, while cut-to-length processing is available for specific profile requirements.
FAQ
What is a PA66 GF25 Large Section Thermal Break Strip?
It is a glass-fiber-reinforced polyamide thermal break profile designed for aluminum extrusions with wider or larger thermal break sections.
Why is PA66 GF25 suitable for large-section profiles?
The 25% glass-fiber reinforcement provides the rigidity and dimensional stability needed for insertion, rolling and long-term profile assembly.
What aluminum systems use large-section thermal break strips?
Typical applications include large aluminum windows, doors, curtain wall mullions, transoms and other wide architectural aluminum profiles.
Does a larger aluminum profile always require a large-section strip?
Not necessarily. The required strip depends on the actual cavity, profile geometry, thermal break width and mechanical engagement structure.
Can Jinxing customize the large-section profile?
Yes. Jinxing can customize the cross-section and dimensions according to aluminum profile drawings or physical samples.
What should be provided for size confirmation?
An aluminum extrusion drawing or sample, required thermal break dimensions and the assembly method are useful for confirming the suitable profile.
