Closed-Cell Foaming Density Rate
The Greek mainland and its extensive archipelago present unique challenging environments for building envelope design and HVAC piping system integrity. Extreme summer solar gains, accompanied by high relative atmospheric humidity in coastal municipalities like Piraeus, Thessaloniki, Patras, and Heraklion, trigger rapid vapor drive. Without high water vapor resistance (high μ-factor), thermal insulation systems degrade fast, leading to CUI (Corrosion Under Insulation), system failure, and severe energy loss.
Modern HVAC-R designs in Greece must strictly align with the KENAK (Greek Regulation on the Energy Performance of Buildings) and the EU Energy Performance of Buildings Directive (EPBD). To satisfy these directives, designers are moving away from traditional open-cell materials like fiberglass, which are prone to moisture absorption, towards high-performance elastomeric NBR/PVC closed-cell foams.
• Coastal High Humidity: Promotes rapid water vapor condensation inside porous insulation materials, rendering standard mineral wool ineffective.
• Strict EU Compliance: Local Greek projects demand Euroclass fire safety certification (EN 13501-1, BS 476 Part 7) and certified low toxic smoke emissions.
• Maritime Sub-Sector Focus: High request for MED-certified marine-grade elastomeric insulation for Greek shipping fleets operating out of Piraeus.
By preventing moisture absorption, Kingflex NBR/PVC rubber foam guarantees a stable, low thermal conductivity rating over a lifespan exceeding 10 to 15 years, eliminating premature retrofits.
| Performance Metric | Kingflex NBR/PVC Standard | Traditional Glass Fiber / Mineral Wool | Benefit for Greek Projects |
|---|---|---|---|
| Thermal Conductivity (λ at 0°C) | ≤ 0.034 W/(m·K) | 0.040 - 0.045 W/(m·K) | Lower energy waste in cooling HVAC systems |
| Water Vapor Resistance (μ-factor) | ≥ 10,000 | 1 (Completely permeable) | Zero condensation in high-humidity islands |
| Service Life in Coastal Areas | 10 to 15 Years (Stable) | 3 to 5 Years (Due to moisture decay) | Significant savings in long-term maintenance costs |
| Fire Safety Classification | Class 0 (BS 476) / Class B (EN 13501-1) | Variable (Depends on binder structure) | Safe for public facilities and escape corridors |
Engineered utilizing high-accuracy automated manufacturing structures to guarantee structural cellular consistency.
Boasting a >98% closed-cell foaming configuration, our NBR/PVC matrix blocks water droplets and gaseous vapor molecules, maintaining dry piping surfaces and stopping rust.
Designed with balanced NBR and PVC polymer proportions, these sheets and tubes offer enhanced resistance to atmospheric salt degradation and high temperatures, ideal for coastal resorts.
Formulated with premium halogenated flame-retardant agents. In case of ignition, the carbonizing surface blocks oxygen penetration, emitting minimal toxic gases in line with Greek building codes.
Established under the parent umbrella of the Jinwei Group, which features an rich industrial lineage spanning over 40 years since its foundation in 1979, Kingflex has grown to be the premiere thermal insulation developer in Northern China. Jinwei Group was the pioneer manufacturer of thermal insulation materials north of the Yangtze River, paving the way for thermal material breakthroughs.

As the construction and HVAC industry moves toward absolute carbon neutrality, building materials must achieve more than just energy savings. Material chemistry must adapt to limit environmental impact throughout the product lifecycle. Kingflex's engineering team is actively pursuing a three-phase green modernization program to support environmental compliance for European specifiers:
We are phasing in next-generation physical foaming agents that yield zero Ozone Depletion Potential (ODP) and negligible Global Warming Potential (GWP), meeting the strictest EU environmental standards.
Our research department is developing bio-sourced monomers to partially replace petroleum-derived NBR. This reduces the carbon footprint of production while maintaining flexibility and insulation performance.
To protect outdoor pipes under Greece's intense UV radiation, we are launching an integrated, factory-applied composite cladding that eliminates the need for manual weather-proof jacketing on-site.
