Strategic Integration: NFRC & Title 24 in France

As global construction moves toward extreme energy efficiency, Grandex Door Solutions leads the transition by applying rigorous USA NFRC (National Fenestration Rating Council) and California Title 24 thermal performance standards to the French market. While France adheres to RE2020 regulations, our expertise in high-insulation door systems allows French developers to exceed baseline energy requirements, ensuring superior thermal bridging protection and sustainable building certification.
