For aluminum profile systems using a simple, straight thermal break cavity, the I-Type design provides a direct connection between the two sides of the extrusion while maintaining a polymer barrier between them. Jinxing supplies Polyamide I-Type Thermal Break Strip as a China factory product with profile dimensions developed around the customer's actual aluminum extrusion and mechanical engagement requirements.
The cross-section is shaped like the letter “I,” with the two ends engaging with the corresponding aluminum profile grooves.
Its relatively straightforward geometry makes the I-Type suitable for many conventional thermal break profile designs, particularly where the aluminum extrusion has matching pockets for strip insertion and mechanical locking.
The important point is not the shape alone. The strip width, thickness, end geometry and groove fit all need to correspond to the aluminum profile.
· Straightforward Profile Geometry — Suitable for aluminum sections designed around a simple thermal break cavity.
· Reliable Mechanical Engagement — The profile can be matched to the aluminum groove for stable assembly.
· PA66 Glass-Fiber Reinforcement — Provides the rigidity needed during insertion and profile processing.
· Consistent Cross-Section — Controlled extrusion helps maintain the dimensions required for profile matching.
· Flexible Size Selection — Different dimensions can be produced for different aluminum extrusion systems.
Jinxing uses PA66 nylon with glass-fiber reinforcement for its thermal break strips. The reinforcement improves the stiffness and mechanical stability of the polyamide profile while keeping the material suitable for extrusion into continuous thermal break sections.
Material preparation is followed by extrusion, cooling, shaping and precision cutting. Incoming material checks can include melt flow index, glass-fiber content and moisture to help maintain batch consistency.
Polyamide I-Type Thermal Break Strip can be used in thermally separated:
· Aluminum window profiles
· Aluminum door profiles
· Curtain wall profiles
· Other architectural aluminum extrusions with compatible I-Type cavities
The final strip size should be selected from the actual profile section rather than only from the application name.
For I-Type thermal break strips, profile compatibility is especially important. Buyers should check:
|
Item |
What to Confirm |
|
Strip width |

|
Strip thickness |
Provides the required separation and fit |
|
End geometry |
Engages correctly with the profile grooves |
|
Insertion method |
Compatible with the production process |
|
Rolling conditions |
Maintains mechanical retention after assembly |
|
Profile drawing |
Confirms the complete cross-section |
Jinxing can produce non-standard I-Type dimensions when an existing size does not match the aluminum extrusion.
During extrusion, Jinxing controls key process conditions such as extrusion temperature, pulling speed and cooling. Production samples are checked for cross-sectional dimensions and surface defects.
Finished strips are inspected before shipment, while relevant mechanical, thermal aging, water resistance and other properties can be evaluated according to the applicable requirements.
I-Type strips can be supplied in straight lengths or coils according to the product specification. Standard straight strips are available at 6 m per piece, while customized cutting can be arranged for specific project requirements.
Jinxing can also provide customized:
· Cross-sectional dimensions
· Special colors
· Cut lengths
· Packaging
· Laser coding
For profile manufacturers developing a new aluminum extrusion, production can start from a drawing or physical sample and proceed through tooling, trial extrusion and final dimension confirmation.
It is a polyamide thermal break profile with an I-shaped cross-section, installed between separated aluminum sections to provide thermal separation within the finished profile.
Its relatively simple cross-section can fit aluminum profiles designed with corresponding grooves and provides a straightforward approach to thermal break assembly.
Jinxing uses PA66 nylon with glass-fiber reinforcement for its thermal break strip production.
Yes. Dimensions, cross-section details, color, length and packaging can be customized according to aluminum profile drawings or samples.
The aluminum extrusion drawing should be used to determine the required strip width, thickness, end geometry and engagement dimensions.
