ThermalBar is the sole Indian originator of high-precision Polyamide (PA66 GF25) thermal break strips. We eliminated the need for imports by building complete in-house extrusion capability — from raw polymer compounding to finished profiles.
Our commitment to Atmanirbhar manufacturing means faster delivery, zero import dependency, and engineering support that speaks your language — literally and technically.
This molecular composition yields identical thermal expansion properties to high-grade aluminum, eliminating structural shear stress across temperature extremes.
Enhancing energy ratings for casement, sliding, and tilt-and-turn aluminum windows in luxury homes and high-rise apartments.
Eliminating thermal bridges across structural glazing and high-rise commercial facades to meet green building certifications.
Securing structural rigidity in heavy-duty hinged, pivot, and folding aluminum door sets across commercial and industrial spaces.
Meeting IGBC, GRIHA, and LEED compliance requirements with verified thermal performance data for sustainable construction.

We don't just manufacture — we engineer. If you need a proprietary strip shape for your window or door system, our team will design, tool, and mass-produce custom polyamide extrusion dies completely in-house.
Submit your CAD drawings or technical specifications, and our engineering team will deliver precision profiles matched to your exact system requirements.
Request Custom ToolingYes. Our PA66 GF25 profiles are engineered to withstand baking temperatures exceeding 200°C — the standard requirement for post-assembly powder coating on aluminum frames. Unlike PVC, there is zero warping or structural deformation.
PVC cannot match the thermal expansion coefficient of aluminum and fails at high baking temperatures. Polyurethane foam lacks structural rigidity. PA66 GF25 combines thermal isolation with mechanical strength, perfectly synchronized with aluminum's expansion behavior, making it the global industry standard.
Yes. While predominantly used in aluminum systems due to matched thermal expansion coefficients, our high-performance PA66 GF25 strips are equally effective in steel framing, UPVC composites, and other structural systems requiring high-strength thermal isolation. Their superior mechanical properties and temperature resistance make them versatile for any advanced architectural application.
We use precision gravimetric dosing systems during compounding to maintain exact 25% glass fiber content in every batch. Each production run is sampled and tested for fiber distribution, tensile strength, and density to ensure zero variance in structural performance.
Absolutely. We offer complete OEM engineering services. Submit your technical drawings or CAD specifications, and we will design, tool, and mass-produce custom extrusion dies perfectly suited to your proprietary aluminum system profiles.
Standard profiles are available with quick turnaround from our Indian manufacturing facility. For custom OEM tooling, lead times vary based on complexity. Contact our engineering team for project-specific timelines and availability.
