Strategically engineered to deliver optimized thermal efficiency ($\lambda \le 0.034$ W/m·K at 0°C) and robust condensation control, our top-tier elastomeric foam tubes are ideal for HVAC, plumbing, and low-temperature process pipework throughout Southern Europe.
Thermal insulation in Spain's commercial, residential, and industrial construction sectors is strictly regulated by the Código Técnico de la Edificación (CTE) and the Reglamento de Instalaciones Térmicas en los Edificios (RITE). Under RITE (specifically IT 1.2.4.2.1), thermal insulation systems must satisfy rigorous criteria regarding energy efficiency, thickness thresholds, and thermodynamic stability. Our closed-cell rubber foam insulation tubes are custom-engineered to meet these requirements across all climate zones in Spain (Zones A to E).
Key parameters like thermal conductivity ($\lambda \le 0.034$ W/m·K at 0°C) and water vapor transmission resistance ($\mu \ge 10,000$) play a crucial role in preventing surface condensation. In high-humidity coastal zones such as Catalonia, Valencia, and Andalusia, poor insulation choices lead to moisture ingress, organic growth, and structural corrosion (Corrosion Under Insulation - CUI). Utilizing Kingflex elastomeric foam provides long-term thermodynamic stability and protects mechanical assets.
As part of the European Green Deal and the Spanish National Integrated Energy and Climate Plan (PNIEC 2021-2030), Spain has committed to reducing greenhouse gas emissions and improving primary energy efficiency. Heating, ventilation, and air conditioning (HVAC) systems in buildings account for nearly 40% of Spain's total energy consumption. High-quality elastomeric insulation acts as a primary tool for operational carbon reduction.
By optimizing insulation on chilled and hot water loops, commercial properties in Madrid, Barcelona, and Seville can reduce thermal transmission losses by up to 85%, cutting utility bills and aiding ESG alignment.
Major cities are investing in District Heating and Cooling (DHC) grids. These systems depend on premium, low thermal conductivity insulation pipes to carry chilled and hot water over long municipal distances without temperature degradation.
Industrial processing facilities—ranging from chemical processing plants in Tarragona to food and beverage hubs in Murcia—rely on NBR/PVC foam tubes to maintain tight control over process temperatures.
Kingflex insulation products are manufactured under rigorous quality systems, utilizing NBR (Nitrile Butadiene Rubber) and PVC (Polyvinyl Chloride) as the main raw materials. This composite formula offers flexibility, high flame-retardant properties, and a closed-cell physical architecture.
Ideal for large diameter HVAC ducts, storage tanks, and irregular system components.

Kingflex Insulation Co., Ltd. represents a professional manufacturing and trading combo for high-end thermal insulation products. Established by the Jinwei Group, which boasts over 40 years of industrial history (established in 1979 as the pioneer of thermal insulation materials north of the Yangtze River), our production facilities are situated in China's green-building material capital, Dacheng.
Our plant operates 5 large-scale automatic extrusion and foaming assembly lines, generating an annual capacity exceeding 600,000 cubic meters. This scale of operation guarantees short lead times, stable supply lines, and consistent material quality for large-scale construction projects across the Spain market.
Our workforce includes 8 professional R&D engineers, 6 dedicated international sales managers, and 230 skilled production technicians, ensuring high quality control from raw material receipt to export logistics. Kingflex is a designated production enterprise certified by the Ministry of Energy, Ministry of Electric Power, and Ministry of Chemical Industry.
Spain's diverse geography demands tailored HVAC design and material selection. Our rubber foam insulation tubes are optimized for the following real-world applications:
Condensation control in commercial high-rises and hotels in Madrid's metropolitan area. Our high water vapor resistance prevents dripping ceiling lines and preserves indoor air quality.
For installations in sunny areas like Andalusia and Extremadura, NBR/PVC foam requires UV cladding or weather-resistant coatings to prevent degradation under intense solar radiation.
Cold room storage, agricultural transport infrastructure, and chemical process cooling lines require thick-walled elastomeric tubes to maintain low energy footprints at sub-zero operations.
Below are real installation snapshots demonstrating the application of Kingflex rubber foam insulation solutions on HVAC and cold-chain pipework.
We provide a comprehensive range of dimensions, wall thicknesses, and material combinations to satisfy every design engineer's specifications.
Kingflex enforces an end-to-end quality management protocol, ensuring every batch of rubber foam insulation shipped to Spanish ports (such as Valencia, Barcelona, and Bilbao) satisfies or exceeds local European compliance codes.
Our products have undergone third-party laboratory evaluations, achieving key national and international certifications:
Every shipment includes complete tracking parameters, production timestamps, and physical testing documentation to ensure supply chain transparency for Spanish project developers.
Our commitment to quality has earned us positive feedback from distributors and MEP contractors in Spain and across the globe.
