Overview
The 62.75-K thermal break strip is a specialty insulating profile made from PA66 reinforced with 25% glass fiber (PA66 GF25). Designed with an extra-wide width of 62.75 mm and a unique K-type geometry, this profile is purpose-built for heavy-duty aluminum systems that demand both high thermal insulation and structural adaptability. Its special shape offers enhanced contact stability and custom fit for complex or oversized architectural profiles.

Material: PA66 GF25 (Polyamide 66 with 25% glass fiber)
Width: 62.75 mm
Profile Type: K structure (custom-fit geometry)
Thermal Conductivity: ≤ 0.3 W/m·K
Tensile Strength: ≥ 80 MPa
Heat Deflection Temperature: ≥ 230°C
Linear Expansion Coefficient: (2.3–2.7) × 10⁻⁵ /K
Color: Black (custom colors available)

The 62.75-K thermal break strip is ideally suited for systems that involve extra-deep, complex-shaped aluminum profiles, such as:
Unitized Curtain Wall Systems with Large Cavities
Offers a stable thermal separation in oversized mullions and transoms, ensuring low U-values without compromising structural integrity.
High-End Commercial Facades
Used in advanced façade systems where both mechanical performance and aesthetic integration are required.
Large Span Glazing and Skylights
Supports wide framing sections used in transparent roofs and atriums, where long-term stability and insulation are essential.
Customized Structural Aluminum Systems
Tailored for profile systems with non-standard grooves or unique internal geometries, where regular strips are incompatible.

Unique 62.75 mm Width + Special K Shape: Accommodates ultra-deep or complex aluminum profiles with greater surface contact
Custom Geometry: Enhances mechanical anchoring and reduces misalignment during assembly
Superior Thermal Performance: Wide contact area provides effective thermal barrier
Dimensional Precision: Manufactured with tight tolerances for seamless integration
Durability in Harsh Conditions: Withstands UV, humidity, and high-temperature stress over long service life
