Thermal Break Strips for Aluminum Profiles | Polyamide Insulation Solutions

A thermal break is a fundamental engineering component strategically inserted within a metal frame, such as an aluminum window or door, to significantly reduce heat transfer. This transfer, known as thermal bridging, is a major source of energy loss in buildings. The principle is to separate the interior and exterior sections of the metal profile with a material of low thermal conductivity, effectively creating a barrier that interrupts the flow of heat. Our specialization lies in the design and production of polyamide thermal break strips, which are mechanically inserted and rolled into the aluminum profile during fabrication. The effectiveness of a thermal break is not merely a function of the material used, but also of its geometric design, the integrity of its bond with the aluminum, and its overall durability. We have invested years in optimizing the profile designs to maximize the insulation path while maintaining the structural strength required to transfer shear and tensile forces between the two aluminum sides. Our one stop service philosophy, realized through Polywell, ensures that the thermal break strip is not viewed in isolation. We provide the entire ecosystem—from the raw polyamide material and extrusion expertise to the downstream equipment—guaranteeing that the final integrated product performs as a reliable, long lasting thermal barrier, enhancing occupant comfort and reducing HVAC energy consumption for buildings across diverse global climates.
