Kingflex
Premium elastomeric insulation configurations certified for commercial HVAC, refrigeration loops, and condensation control in maritime and desert zones.
Israel presents a unique geographical mix of hyper-arid desert zones in the Negev, high-humidity Mediterranean coastal plains (including the dense Tel Aviv-Jaffa metro area), and temperate highland regions like Jerusalem. For mechanical engineers, builders, and MEP consultants, choosing the right elastomeric insulation is critical to control water vapor condensation and thermal losses.
In Israel’s high-tech corridors—often termed "Silicon Wadi"—advanced semiconductor fabrication facilities, bio-pharmaceutical labs, and high-efficiency commercial centers require exact environmental controls. Operating chilled water loops and cleanrooms continuously demands high-performance closed-cell elastomeric rubber foam insulation to prevent structural damage, biological growth, and performance decay.
Kingflex elastomeric rubber foam solutions comply with Israeli Green Building Standard SI 5281, reducing operational carbon footprint while maintaining long-term physical integrity under conditions of high ambient temperature and salt-laden sea air.
Engineered to international mechanical and safety metrics including NBR/PVC composition parameters for optimized thermal and physical performance.
Designed for large-diameter ducts, tanks, and irregular mechanical shapes. Equipped with multi-layered protective options including fiber reinforced foil facings.
Precision-extruded piping cores designed for immediate slip-on application on copper, steel, and plastic HVAC pipelines.

Detailed answers to engineering and commercial questions about rubber foam insulation imports and applications.
It is primarily used to insulate HVAC ductwork, VRF refrigerant lines, chilled water pipes, industrial process piping, and cryogenic systems. Its closed-cell structure helps control thermal losses and prevents water condensation on cold metal surfaces.
Yes, our rubber foam products are formulated with flame retardants. They meet Class 0 / Class 1 fire safety criteria (BS 476 Part 6 & 7), DIN 4102, and UL94, ensuring reliable compliance with building regulations.
Rubber foam is a flexible, closed-cell material that prevents moisture penetration without requiring a separate vapor barrier, making it ideal for refrigeration and cold-water systems. Rock wool is a fibrous material that handles high temperatures and provides excellent fire resistance, making it suitable for hot-water loops, boiler systems, and high-temp industrial applications.
Yes. We offer customized OEM production, including custom wall thicknesses, internal diameters, adhesive backings, and outer cladding options like reinforced aluminum foil (Alu-Clad) for outdoor UV protection.
Our products have passed BS 476, CE, REACH, ROHS, UL94, ASTM, and ISO 9001 certifications. Testing documentation is available upon request for commercial projects.
Yes. Each production run has unique batch numbers printed directly on the carton packaging and insulation skins, allowing full traceability from raw materials to final shipping.
We manufacture sheet rolls in thicknesses ranging from 6mm to 50mm, allowing engineers to select the exact thickness needed to meet local climate and condensation requirements.
When installed and maintained correctly indoors, our elastomeric foam has a typical service life of 10 to 15 years. For outdoor installations, adding a protective UV cladding is recommended to maximize durability.
