Explore our elite collection of elastomeric rubber foam insulation rolls and tubes designed for compliant ceiling penetration and HVAC barrier sealing.
Why systemic thermal isolation and passive fire stopping are non-negotiable in modern commercial construction.
Sealing ceiling voids requires materials that inhibit energy loss while damping noise. Elastomeric closed-cell structures reduce acoustic transfer at penetration interfaces.
Fire retardant properties meeting Class 0, Class 1 (BS 476), and UL94 criteria ensure that in the event of an outbreak, the insulation retards flame propagation instead of feeding it.
A high moisture resistance factor (μ ≥ 10,000) prevents condensation buildup inside ceiling openings, avoiding localized rot and systemic structural decay.
Pioneering tomorrow's fire safety standards using elastomeric polymer engineering.
To eliminate toxic smoke emissions, we are routing R&D toward halogen-free rubber foam. These materials prevent the release of acid gases during high-temperature thermal runaways.
By infusing silica aerogels into standard NBR/PVC polymer matrix, our next-generation shields achieve thinner profiles with doubled thermal resistance (R-value).
Developing hybrid insulation rolls that chemically expand under intense heat (above 180°C) to dynamically seal ceiling penetrations from oxygen ingress.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Kingflex research development and production department is located in well-known capital of green-building materials in Dacheng, China. It is an energy-saving environmental friendly enterprise concentrating on research, development, production, and sales. In operation, Kingflex takes energy saving and consumption reduction as the core concept. We provide insulation solutions by means of consultation, research and development, production, installation guidance, and post-sale service to lead the development of the global building materials industry.
Kingflex was established by the Jinwei Group, which boasts more than 40 years of industrial history. Kingway Group, established in 1979, was the first manufacturer of thermal insulation materials north of the Yangtze River. Decades of research and continuous innovation have cemented our status as trusted global advisors in cold insulation, acoustic damping, and fire-resistant pipeline jackets.
Ensuring consistent quality and reliable lead times for megaprojects worldwide.
Our employees are amazing in their own right, but together they are what makes Kingflex such a rewarding place to work. The Kingflex team is a tight-knit, talented group with a shared vision of giving consistently first-class service to our clients. Kingflex has 8 professional engineers in our R&D Department, 6 professional international sales specialists, and 230 workers in our production department.
At present, our factory is a designated production enterprise certified by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry in China. This elite status allows us to support major national infrastructures and global logistics pipelines seamlessly.
