Product Overview
The YF-25.3-CT2 is a high-precision polyamide thermal break strip, specially designed for premium aluminum windows, doors, and curtain wall systems requiring superior insulation performance and structural stability. With its 25.3 mm width and enhanced CT2 geometry, it provides exceptional bonding strength and thermal barrier properties.
✅ Excellent Thermal Insulation
Made from top-grade PA66 GF25, the YF-25.3-CT2 effectively reduces thermal bridging, boosting the energy efficiency of aluminum profiles.
✅ Enhanced CT2 Tooth Design
The “CT2” knurling-friendly geometry ensures secure mechanical interlocking with aluminum frames, delivering higher pull-out resistance and better stress distribution.
✅ High Dimensional Stability
Maintains precise shape and performance even under extreme temperatures and long-term exposure.
✅ Durable Weather & UV Resistance
Designed for harsh climate zones — with proven resistance to aging, moisture, and UV degradation.
✅ Seamless Integration
Supports standard knurling and crimping processes for fast, efficient, and reliable assembly.
