Component Specifications

Definition
A thermal break insert is a critical component in precision aluminum extrusion profiles, designed to interrupt thermal conductivity between interior and exterior sections. It consists of a polyamide or polyurethane strip mechanically or chemically bonded between aluminum profiles, creating a barrier that minimizes heat flow while maintaining structural integrity. This component is essential for meeting energy efficiency standards in building construction and industrial applications.
Working Principle
The thermal break insert operates on the principle of thermal resistance by introducing a material with low thermal conductivity between two aluminum sections. This creates a thermal barrier that reduces heat transfer via conduction, while the mechanical connection maintains structural stability. The insert's design ensures minimal thermal bridging, preventing energy loss and condensation formation.
Materials
Polyamide 6.6 (PA66) with 25% glass fiber reinforcement, polyurethane (PU), or other engineered polymers with thermal conductivity below 0.3 W/m·K. Aluminum contact surfaces may have serrations or adhesive coatings for enhanced bonding.
