View SpecificationsThe industrial and commercial construction sectors in Spain are undergoing a massive transformation. Driven by the aggressive goals of the European Green Deal and the Spanish National Integrated Energy and Climate Plan (PNIEC), energy optimization is no longer optional. Under this regulatory landscape, closed-cell elastomeric rubber foam insulation stands out as a critical building block.
In Spain's varied climates—from the humid Mediterranean coastlines of Valencia and Barcelona to the severe temperature fluctuations of Madrid and Castile—insulation materials must perform flawlessly under stress. Condensation control is the primary structural challenge in Southern Spain during the summer, when chilling systems run continuously in high ambient humidity. If moisture penetrates an insulation barrier, the thermal conductivity rises dramatically, resulting in energy loss, corrosion under insulation (CUI), and indoor air quality concerns.
Spanish Building Codes (CTE DB-HE) mandate strict rules for thermal transmittance and system efficiency. Closed-cell elastomers play a major role in achieving the required energy saving targets.
With a high water vapor diffusion resistance factor (μ ≥ 10,000), Kingflex NBR/PVC structures stop atmospheric moisture ingress, eliminating the risk of mold growth and structural dampness.
Meets the requirements of CTE DB-HR (Protection against Noise) by decoupling system pipe vibrations from wall brackets and structures in high-occupancy commercial projects.
Standard open-cell or fibrous materials often fall short in applications requiring robust chemical resistance, flexibility, and a built-in vapor barrier. Elastomeric rubber foam combines these criteria inside a single, easy-to-install material. Leveraging a dense, micro-cell layout, our rubber foam rolls and accessories maintain continuous thermal efficiency over a service lifespan of 10 to 15 years.
Furthermore, local safety regulations require class-leading fire behavior. Under the European Euroclass system (EN 13501-1), Kingflex systems are engineered to meet strict ratings, restricting smoke density and preventing fire droplets, which is essential for evacuation routing in Spanish hospitals, high-occupancy hotels, and municipal complexes.

Jinwei Group Industrial History
Dedicated R&D Specialists
Kingflex Insulation Co., Ltd. stands as a premier modern production combo for thermal and acoustic insulation systems. Located in Dacheng, China—historically recognized as the capital of energy-saving construction materials—our operations cover research, high-precision extrusion manufacturing, and direct global distribution.
As part of the Jinwei Group, established in 1979 as a pioneer in thermal materials north of the Yangtze River, we maintain over four decades of development expertise. Our facility features five large automatic assembly lines, ensuring consistent density, cell structure, and fire performance properties.
Kingflex operates under a core philosophy of environmental responsibility, reducing power requirements across the life cycle of our products. Our technical formulations are completely free of ozone-depleting substances, halogenated additives, and high-VOC raw components, ensuring safety and environmental compliance for green building projects under the Spanish BREEAM and LEED green rating systems.
In high humidity environments like the Balearic Islands, Andalusia, and the Costa Brava, HVAC chilled water lines operate under intense vapor pressure. Conventional materials risk early saturation, causing surface condensation, structural ceiling damage, and thermal failure. Kingflex elastomeric tubes, combined with Kingflex thermal insulation glue 520 and vapor-proof foil tapes, create a continuous sealed barrier to eliminate condensation risks.
With Spain leading in solar thermal integration, insulation must withstand high temperatures and UV degradation. Our special elastomeric structures handle temperature ranges up to 105°C, making them suitable for domestic hot water (DHW) loops and solar thermal piping across Southern Spain.
In offices and hotels in Barcelona and Madrid, air conditioning fan units generate significant structural noise. Using Kingflex elastomeric sheets wrapped on rectangular galvanized steel ducts dampens vibration noise, contributing to compliance with local acoustic comfort requirements.

View SpecificationsAs EU regulations tighten regarding chemical contents and the emissions profiles of construction elements (REACH & RoHS guidelines), the next generation of insulation systems must continuously evolve. Kingflex's engineering department focuses on developmental research across three key areas:
We are researching the integration of renewable, plant-based materials into our rubber matrix, reducing reliance on fossil fuels while maintaining the high performance of closed-cell insulation.
To support high Indoor Air Quality (IAQ) requirements in projects like classrooms, hospitals, and high-occupancy corporate hubs, we are expanding our zero-halogen formulations to minimize smoke toxicity during fire events.
With urbanization rising in Madrid, Barcelona, and Seville, noise control is a priority. We are developing composite systems that combine thermal elastomeric layers with dense mass-loaded vinyl sheets to provide simultaneous thermal control and sound insulation in a single installation step.
