View SpecsBelgium stands at the geographic and logistical center of Europe. Municipal and national mandates, including the Flemish Energy Performance (EPB) regulations and Brussels' Passive House standards, have set incredibly high expectations for modern insulation materials. Traditional halogenated flame-retardant foams are being phased out in public spaces, commercial complexes, and data centers due to safety concerns regarding acid gas releases in fire conditions.
In the event of fire, halogens (such as chlorine and bromine) release highly corrosive acid fumes (like HCl). These fumes pose a lethal threat to occupants and can destroy millions of euros worth of sensitive microelectronics in server farms and switching centers in Brussels, Ghent, and Antwerp. Our Halogen-Free Elastomeric Foam (HF-Elastomeric) solves this challenge by implementing an innovative mineral-based flame retardant matrix that prevents toxic gas release and minimizes smoke density, satisfying the EU's strict EN 13501-1 s1, d0 class expectations.

Kingflex Insulation Co., Ltd. is a leading professional manufacturer and exporter specializing in high-end elastomeric thermal insulation systems. Kingflex’s advanced research, development, and state-of-the-art production base are strategically located in Dacheng, China—historically recognized as the capital of green-building materials. As an energy-saving, environmentally conscious manufacturer, Kingflex prioritizes sustainable development, carbon footprint reduction, and energy efficiency.
Established by the prestigious Jinwei Group, which boasts over 40 years of pioneering history dating back to 1979, Kingflex was built upon a legacy of innovation. Jinwei Group was the first recognized manufacturer of thermal insulation materials north of the Yangtze River. Today, Kingflex carries that legacy forward into international markets, integrating design consultation, customized production, site installation guidance, and dedicated post-sale support to supply first-class global building material solutions.
Leveraging scale, advanced material science, and seamless global logistics to serve Belgian engineering projects.
The thermal insulation market requires a delicate balance between high technical performance and cost control. Operating out of our Dacheng production facility, Kingflex harnesses massive raw material supply chains and automated processes to lower standard unit costs compared to local European competitors, without compromising on materials parameters.
Our logistics pipeline is optimized for shipments into European hubs like the Port of Antwerp-Bruges and the Port of Zeebrugge. We offer custom container consolidation, direct factory clearance, and customized sheet/tube dimensions to minimize on-site cutting waste. This efficiency significantly reduces total project turnaround times and labor expenses for HVAC contractors in Belgium.
To ensure absolute peace of mind for engineering, procurement, and construction (EPC) contractors in the EU, Kingflex provides comprehensive certification files. All products are verified by third-party testing institutions to meet European Union construction product directives (CE marking), EN 13501-1 fire parameters, REACH safety declarations, and RoHS guidelines.
Our international business division operates with dedicated support channels for European buyers, delivering precise product traceability, technical drawings, CAD data, and post-delivery installation guides designed for high-stress HVAC and industrial piping setups.
