The 34.0-K5 thermal break strip is a wide-format insulating profile made from high-strength PA66 GF25 material. Engineered for ultra-deep aluminum profiles, its 34mm width and K5-type structure provide enhanced thermal separation, excellent mechanical performance, and dimensional stability. It’s ideal for large-format façade and high-load architectural systems where energy efficiency and structural performance must go hand-in-hand.
Ultra-Wide Thermal Barrier: 34mm width delivers superior insulation performance for large profile systems
K5 Structural Geometry: Reinforced design improves mechanical load-bearing capability
Excellent Dimensional Accuracy: Ensures tight fits and minimal deformation during assembly and long-term use
Aging and Weather Resistant: Withstands UV, moisture, and temperature extremes
Flexible Integration: Compatible with both European and international aluminum profile systems

Large-Spec Aluminum Curtain Wall Systems
Provides thermal breaks for thick aluminum frames used in high-rise and expansive glass curtain walls, maintaining performance in both extreme cold and heat.
High-Performance Commercial Door Systems
Ideal for oversized entrance systems in commercial buildings, airports, and shopping centers where wide profiles require maximum structural support and insulation.
Energy-Efficient Building Envelopes
Supports compliance with international energy codes and building sustainability targets (e.g., passive house, LEED, BREEAM) by reducing heat loss through structural frames.
Heavy Structural Glazing Systems
Applicable in structurally glazed façades with load-bearing aluminum profiles, where material rigidity and reliable thermal separation are vital.
Severe Climate Zones
Perfect for use in desert, alpine, or coastal environments, where buildings face strong temperature swings, high humidity, or UV exposure.
