44mm Polyamide Thermal Barrier Strips for Aluminium Doors

Technical Specifications

Overview

Aluminium conducts heat more than 500 times faster than polyamide, which makes direct use of aluminium frames a major source of energy loss. Our 44 mm thermal barrier insulation profiles solve this problem by placing a reinforced polyamide strut between interior and exterior aluminium sections. This thermal barrier cuts the heat bridge, improves U-value, and reduces condensation risk. Manufactured with glass fiber reinforced polyamide, the strut is designed with multidirectional fibers to deliver both thermal separation and mechanical strength. With this wider separation, you gain reliable energy savings and long-lasting frame performance even under severe climates.

Product Features

• Creates a 44 mm thermal separation – Provides a wide insulating barrier that lowers both heating and cooling loads, helping buildings cut energy demand throughout the year.

• 3D glass-fiber reinforcement – Multidirectional fibers transfer loads securely, ensuring frames resist wind pressure and glazing weight without compromising thermal performance.

• Maintains frame durability and dimensional stability – Withstands seasonal temperature swings, keeping aluminium frames free from distortion and extending service life.

• Reduces condensation – Controls temperature transfer across aluminium sections, preventing moisture build-up that can damage interiors and reduce frame integrity.

• Wide cavity functionality – Offers design flexibility by accommodating gaskets, drainage channels, or acoustic upgrades, making the system adaptable to complex project needs.

• Stable at coating temperatures up to 200 °C – Supports post-assembly powder or liquid finishing, enabling dual-color or custom designs without reducing performance.

Product Advantages

• Achieves superior U-values – Wide separation improves insulation efficiency in curtain wall and façade systems, enabling compliance with strict energy codes.

• Supports wider separation than typical systems – Offers stronger thermal performance compared to standard barriers, meeting advanced passive house and net-zero requirements.

• Provides excellent mechanical response – Reinforced polyamide maintains stability under heavy glazing and high wind loads, ensuring safe and reliable operation.

• Enhances building sustainability – Reduces overall energy consumption and lowers CO₂ emissions, aligning with global green building and sustainability goals.

• Consistent quality control – Strict production checks ensure reliable shear strength, precise fit, and repeatable performance across all project deliveries.

Product Applications

• High-performance curtain wall and façade systems – Suitable for commercial and public buildings demanding long-term efficiency, safety, and visual quality.

• Aluminium windows and doors with wide breaks – Provides thermal separation for systems requiring larger cavities to meet energy and comfort standards.

• Passive house and net-zero energy projects – Delivers the thermal performance necessary for buildings designed to achieve the lowest possible energy consumption.

• Hospitals, airports, and high-rise buildings – Ensures reliable comfort and system durability in environments with strict operational and safety requirements.

• Large glazing systems – Controls condensation and maintains structural strength, supporting long-span glass façades and complex architectural designs.
