Kingflex
Direct from standard-compliant manufacturing bases. Closed-cell technology designed for extreme temperature profiles and critical HVAC application fields.
Understanding BS 476 Part 7 Class 1 and the global commercial paradigm shift in high-performance thermal barriers.
This critical British Standard specifies the test method for measuring the lateral spread of flame along the surface of a product oriented in the vertical position. Achieving Class 1—the highest rating under this specific testing section—guarantees that the materials exhibit extremely restricted flame propagation properties, reducing risks in enclosed building environments and industrial high-risk installations.
Worldwide regulatory authorities are strengthening building codes, aligning regional directives with British fire safety protocols. From mega-scale LNG liquefaction plants to dense commercial HVAC piping structures, designers mandate Class 1 compliant materials to mitigate hazard vulnerabilities, directly reducing liability and insurance costs.
Untested substitutes introduce severe structural risks. Using products verified by international agencies (BS 476, CE, REACH, UL94) guarantees the stability of thermal conductivity, aging characteristics, and fire safety performance over decades of continuous operational load.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Located in Dacheng, China—a renowned hub of green-building materials—we are an energy-saving and environmentally friendly enterprise. Our core operations span research, development, and high-volume production of elastomeric rubber foam solutions.
In practice, Kingflex prioritizes energy efficiency and environmental protection. We offer end-to-end system solutions—encompassing technical consultation, tailor-made R&D, structural installation guidance, and dedicated post-sale support—to lead the global building materials sector.
Established under the aegis of the Jinwei Group, which possesses a rich history spanning over four decades. The group commenced its operational journey in 1979 as the pioneering manufacturer of high-quality thermal insulation materials north of the Yangtze River. This deep heritage ensures unmatched reliability in manufacturing and technical support.
