Kingflex
Specially calibrated elastomeric materials optimized for heavy commercial complexes and high-demand HVAC pipelines in Manila.
Flexible elastomeric NBR foam rolls designed to combat intense relative humidity in Metro Manila building installations.
Advanced cold-insulation systems engineered for low-temperature industrial processes and deep cryogenic storage lines.
Superior pipe insulation manufactured from dynamic NBR/PVC blend, offering excellent thermal conductivity control.
Halogen-free environmental elastomeric sheets meeting strict green building codes and toxicity guidelines.
Metro Manila operates under a tropical wet and dry climate classification (Köppen Aw), marked by persistently high ambient air temperatures, averaging 27°C to 34°C, paired with intense relative humidity levels that often top 85% during the monsoon months. Under these extreme conditions, the thermodynamic dew point swings dangerously close to the operational temperatures of chilled water pipe networks and central air conditioning ducts.
When raw copper or carbon steel conduits are exposed without a highly resistant barrier, condensation triggers immediately. This leads to continuous moisture dripping, degrading ceilings, encouraging mold, and driving Corrosion Under Insulation (CUI). Kingflex NBR/PVC rubber foam sheets prevent these failures by utilizing a completely closed-cell configuration with a water vapor diffusion resistance factor (μ) exceeding 10,000. This design acts as a built-in vapor barrier, keeping heat transfer coefficients stable over years of operation.
Integrating advanced engineering and production scales to lead energy-saving insulation projects globally.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for high-end thermal insulation products. Our R&D and manufacturing hub is located in Dacheng, China—historically recognized as the capital of green-building materials. Concentrating heavily on the convergence of research, development, and environmental safety, Kingflex prioritizes energy conservation and consumption reduction as core performance indexes.
By offering structural consulting, targeted chemical development, installation training, and responsive post-sale services, Kingflex has established itself as an integrated partner for structural and industrial insulation needs.
Kingflex was founded by the Jinwei Group (now Kingway Group), an industrial pioneer established in 1979. With over 40 years of specialized manufacturing history, the parent group was the very first thermal insulation material manufacturer built north of the Yangtze River. This deep heritage ensures our formulas, QC standards, and material properties are backed by decades of thermal research.
While our individual teams bring specialized skills to our operations, together they form a close-knit group focused on first-class service. Our organization features 8 professional engineers in the R&D Department, 6 international logistics coordinators, and 230 technicians on the assembly line.
Understanding fire safety regulations and green code integrations required for commercial infrastructure in the National Capital Region (NCR).
For high-occupancy structures such as BGC office towers, QC shopping malls, and Pasay residential skyscrapers, fire safety is critical. The Philippine Bureau of Fire Protection (BFP) strictly enforces RA 9514 (Fire Code of the Philippines), demanding structural insulation materials that resist flame propagation and limit toxic smoke emission.
Kingflex NBR/PVC elastomeric rubber foam sheets are manufactured to meet BS 476 Part 6 (Fire Propagation) and Part 7 (Surface Spread of Flame) Class 0 ratings. In the event of a fire, the closed-cell rubber self-extinguishes, produces no flaming droplets, and significantly limits smoke density, protecting evacuation pathways.

The closed-cell design blocks water absorption, eliminating the risk of internal mold or mildew growth in high-humidity climates.
Dampens structural vibration and airborne noise inside multi-story air ducts and mechanical plant rooms.
Formulated to resist airborne salts, acids, and solar exposure in exposed rooftop marine and coastal settings.
Engineered configurations designed for direct application across commercial construction and complex pipe arrays.
Perfect for large air handling units (AHU), expansive ducts, structural concrete walls, and broad storage tanks. The flexibility of our sheet rolls allows rapid wrapping around circular and rectangular profiles alike, minimizing seams and reducing cold bridging risk.
Specifically manufactured for direct installation over copper piping, steel water supply lines, and chilled water conduits. Fitted slide-on or slit-and-glue designs ensure snug joints, reducing labor costs on commercial project sites.
