What Are Polymer Components for Thermal Break Windows?
Polymer components for thermal break windows are engineered parts placed between the interior and exterior sections of aluminum profiles to interrupt the thermal bridge and prevent rapid heat and cold transfer between inside and outside. These components are the beating heart of a thermal break system — without them, aluminum windows cannot achieve effective thermal performance.
A thermal break window without polymer insulating parts is just a standard aluminum window that conducts heat rapidly. But when these polymer parts are engineered with precision and installed correctly, the aluminum profile becomes an efficient thermal insulator.
Why Are Polymer Components Used in Thermal Break Windows?
Aluminum, as a metal, has a very high thermal conductivity. If a window is made entirely of aluminum, heat transfers from inside to outside in winter, and from outside to inside in summer. This phenomenon, called a thermal bridge, causes energy loss, condensation on profiles, and reduced thermal comfort.
Polymers, unlike metals, have a very low thermal conductivity. That’s why placing a polymer piece between two aluminum halves interrupts the heat transfer path. This polymer part must simultaneously have several key properties: high thermal resistance, sufficient mechanical strength, resistance to moisture and UV, dimensional stability, and strong bonding to the aluminum profile.
Types of Polymer Components for Thermal Break Windows
1. Main Thermal Break (Polyamide Strip): The most important polymer component, placed as a strip between two aluminum profiles. Typically made of glass-fiber-reinforced polyamide PA66, offering a combination of strength and insulation.
2. Side Polymer Profiles: Parts used at corners and connection points of the profile, serving both structural and insulation roles.
3. Polymer Seals and Gaskets: EPDM, TPE, or PVC gaskets installed at glass-to-profile contact points and sash closing points, preventing air, water, and sound infiltration.
4. Hardware Insulating Parts: Small polymer components placed between metal hardware and the aluminum profile to prevent new thermal bridges.
5. Supplementary and Decorative Profiles: Polymer parts used to complete the window’s appearance, cover joints, or add decorative details.

Manufacturing Process of Polymer Components
These components are typically produced using the polymer profile extrusion method:
-
Preparation of polymer raw materials (PA66, PVC, or polyurethane granules)
-
Melting materials in an extruder
-
Passing the polymer melt through a die with a specific cross-section
-
Cooling and reaching final dimensions
-
Cutting, packaging, and quality control
This process enables mass production with high dimensional accuracy and reasonable cost. Custom polymer parts manufacturing with dimensions and specifications tailored to the client’s needs is also available.
