A thermal-break panel separates the inner and outer steel skins with a low-conductivity polymer barrier, cutting the cold bridge that runs through a conventional bonded skin [ESTIMATE]. The need is easy to demonstrate: published benchmark data for a premium 42 mm PU panel shows U 0.5 W/m²K for the panel alone but U 1.3 W/m²K for the installed door — the difference is thermal bridging at joints, edges and fixings [SOURCED https://www.renrendoc.com/paper/308976706.html].
RAX engineers thermal-break panel constructions to order on its automated PU foam line and CNC punching/bending center: galvanized skins 0.4–1.5 mm, PU core 40–50 mm, full RAL batch color, SGS material reports. Panels are validated in complete door systems from -30 °C cold storage to +50 °C desert conditions.
Thermal-break construction concept is an industry design convention [ESTIMATE] pending RAX per-project test data. Panel-vs-installed U-value benchmark (0.5 / 1.3 W/m²K) is published Hörmann EPU40 data [SOURCED https://www.renrendoc.com/paper/308976706.html]. RAX-specific claims are from the approved brand brief.

Set the required installed-door U-value and the interior/exterior temperature differential before choosing construction.
Confirm the polymer break path and skin gauge; conventional panels bridge at the skins [ESTIMATE].
Check interior-face temperature at design conditions to avoid condensation and frost lines at joints.
Benchmark data shows installed U-values can be 2–3× panel-only values [SOURCED https://www.renrendoc.com/paper/308976706.html] — request the assembled-door figure.
RAX supports full private-label production of the Thermal Break Door Panel: custom RAL panel colors, operator matching, packaging printing and installation-manual translation (EN/ES/FR/AR/RU). Start with an OEM sample and scale to container-load branded production. Custom molds, Tooling records are archived for up to 5 years — no extra tooling fee on repeat orders, all under strict NDA.
Industrial, commercial and garage doors and gates — the harmonized basis for CE marking.
Safety in use of power-operated doors — force limits and test methods for operators.
Wind (EN 12424), thermal (EN 12428), fire (EN 1634-1) etc. confirmed per product during enrichment.
Thermal-break panels are produced to your door width × height in RAX’s 40–50 mm PU range, with break geometry and skin gauge engineered to your U-value and condensation targets (construction concept is an industry convention [ESTIMATE]). Share your temperature differential and opening size; we reply with technical confirmation, from prototype to container-load with full flexibility on order quantity.
We are a pure manufacturer and do not provide on-site installation. Every order ships with an English installation manual, wiring diagrams for your local installation team; operators are pre-set and tested before dispatch.
RAX holds ISO 9001:2015 and CE to EN 13241 (industrial door product standard) and EN 12453 (operator safety), with SGS material reports and product liability insurance. Components are engineered to help the finished door satisfy EN 12604 (mechanical aspects: strength, cycle durability, finger-pinch and spring/cable safety), and product-specific test data (fire, wind, thermal) is confirmed per project against the matching standard.
Yes. RAL panel colors, operator matching, packaging printing and manual translation (EN/ES/FR/AR/RU) are all supported, from an OEM sample to container-load branded production.
Sample 7–15 days; standard container 12–20 days; custom first order 20–35 days. Door body 2-year warranty, operator/motor 3 years (servo 5 years), with spare parts dispatched by DHL/FedEx within warranty.
Factory inspection report, 100,000-cycle fatigue test record, FAI / pre-assembly photos, English installation Manual + Wiring diagrams, CE Declaration of Conformity, and export packing (steel frame + pearl cotton + stretch film).
