Providing the critical thermal performance, structural reliability, and acoustic barrier requirements for modern industrial and commercial developments.
Glass wool insulation blankets feature a highly complex system of microscopic air pockets entrapped within fine silica glass fibers. This micro-structure actively resists heat transfer via conduction and convection, delivering exceptionally low thermal conductivity. Over decades of operation, these fibers maintain their structural resiliency without settling, assuring long-term thermal resistance (R-values) under varying temperature extremes.
By leveraging its porous fiber matric structure, glass wool acts as a natural acoustic trap. High-frequency HVAC reverberations, machinery vibrations, and ambient structural noises are systematically absorbed as sound energy dissipates into minor thermal energy within the dense glass fibers. This acoustic attenuation profile is critical for hotels, healthcare facilities, and modern office spaces.
Engineered from naturally non-combustible inorganic materials, premium glass wool insulation does not support flame spread or generate toxic smoke. When integrated into envelope assemblies or partition walls, it functions as a critical thermal barrier, preventing flame migration and providing invaluable evacuation windows during fire events, aligned with ASTM, BS, and CE standards.
Combining over four decades of thermal insulation heritage with state-of-the-art automated manufacturing capacity.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our dedicated research development and production department is situated in the well-known capital of green-building materials in Dacheng, China. As an energy-saving, environmentally friendly enterprise, we concentrate on advanced R&D, high-volume production, and comprehensive global sales.
Our core operating concept is built on active energy saving and consumption reduction. We provide full-scope insulation systems through technical consultation, dedicated R&D production, expert installation guidance, and high-standard post-sale service designed to lead the development of the global building materials industry.
Kingflex is established by the Jinwei Group, which has a legacy spanning more than 40 years. Established in 1979, Kingway Group was the first manufacturer of thermal insulation materials north of the Yangtze River. This rich historic depth ensures that our processing methodologies, material selection, and quality management protocols represent generations of expertise refined for modern industrial standards.

The technical foundation that ensures consistent output of advanced insulation materials.
Our employees are amazing in their own right, but together they are what makes Kingflex such a fun, rewarding, and highly efficient 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.
Currently, our R&D department features 8 professional engineers who continuously optimize cell formulation, fire-retardancy metrics, and fiber tensile strengths. Our international trading team is staffed with 6 professional international sales specialists to assist in global procurement logistics, while our production lines are operated by 230 dedicated workers.
We believe in maintaining control over physical properties. Through extensive testing inside our testing rooms, we consistently check factors like flame propagation index, smoke density, moisture barrier properties, and thermal conductivity coefficients.
Kingflex materials undergo systematic evaluations and are certified compliant with international benchmarks. Our products have passed BS 476, CE, REACH, RoHS, UL94, and ASTM standards, offering peace of mind to safety inspectors, project managers, and property developers globally.
Strategic geographic location coupled with raw material availability secures unmatched delivery speed.
Our plants are based within Dacheng, China, the premier green building materials manufacturing cluster. This provides immediate access to high-grade silica, raw polymer compounds, packaging supplies, and industrial gas networks. By concentrating our raw material loop, we reduce internal logistics emissions and maintain highly competitive cost structures.
With 5 fully-automated continuous production lines operating under strictly managed parameters, Kingflex maintains an annual production capacity exceeding 600,000 cubic meters. This structural capacity allows us to absorb large, fast-tracked infrastructure orders without compromising on product consistency or lead times.

We take deep responsibility for the energy-saving profile of our materials. Our company supply mission is structured around two key goals:
Quick answers regarding performance characteristics, compliance certifications, logistics, and applications.
It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation and sound insulation.
Yes, our rubber foam insulation is fire retardant, which meets the safety standards of building and industrial projects.
Rubber foam is flexible, closed-cell and moisture-proof, suitable for HVAC and building insulation; rock wool is high-temperature resistant and fireproof, suitable for industrial high-temperature pipeline insulation.
Yes, we support OEM services to meet different project dimensions, thickness variations, facings (such as aluminum foil clad), and density parameters.
Our products have passed BS 476, CE, REACH, ROHS, UL94, ASTM and other international certifications, ensuring product quality and compliance with global standards.
Yes, all Kingflex products have batch traceability, allowing us to track production lines, raw materials batches, and quality inspector assignments.
We can produce thicknesses ranging from 6mm to 50mm based on specific thermal protection requirements.
With correct installation and standard ambient conditions, the average service life ranges from 10 to 15 years.
We utilize high-tensile glass fibers bonded with specialized thermosetting resins. This guarantees high structural spring-back, preserving the air-cell voids that prevent conduction even after transport compression or vertical application installation.
