Send Inquiry NowIsrael is a high-growth industrial and technological hub, requiring advanced building envelopes and specialized industrial thermal barriers. The local climate varies from the hot, arid Negev desert to the humid Mediterranean coastline of the Tel Aviv Metropolitan area. This climate creates complex challenges for energy-efficient building systems. In addition, the Israeli building code, particularly standard SI 5281 (Sustainable Buildings), sets strict benchmarks for energy performance, heat gain coefficients, and eco-friendly raw materials.
Industrial settings like chemical processing installations in Haifa Bay, gas processing structures near the Tamar and Leviathan gas pipelines, and manufacturing parks in Yokneam require top-tier fire safety and thermal performance. Rock wool insulation (stone wool) has become the preferred option for these applications because it can withstand temperatures exceeding 1000°C without melting. This property helps slow the spread of fire and protects critical structural elements.
Our rock wool insulation products are designed to meet thermal, acoustic, and fire protection requirements simultaneously. By using basalt rock as the primary raw material, our manufacturing process produces fiber matrices with low thermal conductivity (typically $\lambda \le 0.035$ W/m·K at 25°C) and excellent acoustic absorption.
| Product Standard Specification | Thermal Conductivity ($\lambda$) | Density Range | Fire Safety Standard Compliance |
|---|---|---|---|
| Basalt Rock Wool Slab / Board | 0.034 - 0.038 W/m·K | 40 - 160 kg/m³ | EN 13501-1 (A1), SI 755 (Non-Combustible) |
| Reinforced Aluminum Foil Rock Wool Blanket | 0.035 - 0.040 W/m·K | 60 - 120 kg/m³ | BS 476 Part 4/6/7 Certified |
| High-Temperature Pre-Formed Pipe Shells | 0.033 - 0.036 W/m·K | 80 - 150 kg/m³ | ASTM C547 Compliant |
| Acoustic Dampening Open-Cell Glass Wool | 0.038 - 0.042 W/m·K | 24 - 48 kg/m³ | UL 94, Class 0 rating |
Kingflex Insulation Co., Ltd. is a major manufacturer and trade combo for thermal insulation products, providing direct access to reliable supplies and customized engineering. Operating out of Dacheng, China—a hub for green building materials development—Kingflex has built a production facility designed for scale, quality control, and cost-efficiency.
Our operations utilize 5 large automatic assembly lines, enabling an annual production capacity of over 600,000 cubic meters. This scale allows us to fulfill large orders for Israeli infrastructure developments, such as the Ashdod Port Expansion, Jerusalem Light Rail depots, and power generation facilities in Hadera. By controlling our supply chain, we offer direct factory pricing, customized density profiles, and reliable lead times. This helps minimize risk for procurement managers working in fluctuating raw material markets.
Kingflex Insulation Co., Ltd. was established by the Jinwei Group, which brings over 40 years of manufacturing history. Established in 1979, the group was the first thermal insulation materials manufacturer north of the Yangtze River. Today, our research, development, and production facility focuses on energy-saving, environmentally friendly insulation systems.
We prioritize energy efficiency and consumption reduction. Our services support clients throughout the project lifecycle, including consultation, customized design, factory production, installation support, and post-sale technical service.
Since our founding in 1979, we have adapted to new technologies and changing international standards. Our manufacturing processes incorporate advanced raw material selection, specialized automated curing ovens, and online visual inspection systems. This ensures consistent density and fiber structure for every production run of rock wool and elastomeric rubber foam.
We serve projects in construction, petroleum refining, petrochemical manufacturing, defense aerospace, and deep cryogenic processing. Over the past 16 years, Kingflex has exported to more than 66 countries, establishing a reliable global distribution network.
How our technical department customizes physical parameters to meet high performance standards.
Our facility features an dedicated R&D department staffed by eight senior materials engineers. We focus on improving the physical properties of our basalt insulation fibers to achieve better thermal resistance and durability in challenging environments.
Through physical modification and raw material refinement, our R&D team has developed low-shot rock wool sheets. This type of insulation contains fewer non-fibrous particles (shot), which helps maintain thermal resistance and prevents insulation settling or degradation in high-vibration industrial settings.
We also test our materials under simulated coastal conditions to check for Corrosion Under Insulation (CUI). Basalt wool with low leachable halide ions (chlorides and fluorides) helps minimize galvanic corrosion on steel pipe outer surfaces. This protection is critical for chemical plants located near coastal saltwater environments.
Every production batch undergoes strict quality control to meet global and Israeli building regulations.
Our thermal and acoustic solutions are tested and certified to verify key safety and performance metrics, including BS 476, CE, REACH, RoHS, UL94, and ASTM. This comprehensive documentation supports building compliance audits and general contractor approvals across Israel.
Modern high-rises in Tel Aviv feature glass and aluminum curtain walls. These facade systems require perimeter fire barriers (spandrel insulation) to prevent fire from moving between floors. High-density Kingflex rock wool boards, combined with steel structural backing, provide fire containment along the building envelope.
In processing plants, steam lines and catalytic converters operate at high temperatures. Our pre-formed rock wool pipe shells offer insulation that withstands high heat, helping control process temperatures, save energy, and protect personnel. Their low chloride content also reduces the risk of corrosion under insulation (CUI).
Israeli summers bring high temperatures and humidity along the coast, leading to condensation risks on HVAC air ducts and chilled water pipes. For these installations, closed-cell elastomeric rubber foam sheets and tubes complement mineral rock wool insulation. The elastomeric material serves as a moisture barrier to protect systems from damp-related damage.
