Technical DataAs one of Central Europe's most prominent industrial and manufacturing hubs, the Czech Republic plays a pivotal role in the European automotive, heavy machinery, and chemical processing sectors. Regions like Central Bohemia, Moravian-Silesian, and South Moravia are undergoing rapid modernization, fueled by the imperative to align with EU Green Deal goals and local energy efficiency requirements.
In modern HVAC, district heating, and process plant setups across Pilsen, Brno, and Prague, thermal insulation is no longer just about basic temperature maintenance; it is a critical strategy for energy containment. Tightening regulations under the Energy Performance of Buildings Directive (EPBD) demand insulation materials that possess extremely low thermal conductivity, durable vapor barrier properties, and superior fire resistance.
This shift in requirements has driven demand for high-performance closed-cell elastomeric rubber foam sheets. Unlike traditional open-cell materials, rubber foam structures prevent the ingress of ambient humidity, protecting mechanical systems from Corrosion Under Insulation (CUI)—a major concern in industrial facilities across Central Europe.
Kingflex Insulation Co., Ltd. operates as a leading manufacturing and trading complex dedicated to high-grade thermal insulation products. Our advanced research, development, and production divisions are located in China's green building materials industrial zone in Dacheng. As an energy-focused, environmentally progressive enterprise, Kingflex integrates continuous research, bulk manufacturing, global sales, and post-installation support into unified solutions.
Established by the Jinwei Group, which boasts a heritage spanning more than 40 years since its founding in 1979, Kingflex benefits from deep technical expertise. Jinwei Group was the pioneer manufacturer of thermal insulation materials north of the Yangtze River, building a solid foundation in material science and raw material sourcing.
Currently, Kingflex runs 5 fully automated, high-output production lines with an annual capacity exceeding 600,000 cubic meters. Our systems are recognized and recommended by industrial authorities, making Kingflex a trusted partner for large-scale energy, power generation, and chemical projects worldwide.

Technical DataKingflex NBR/PVC closed-cell elastomeric thermal insulation products are developed to offer consistent thermal barrier properties over a long service life. The fine-celled structure blocks air movement and convective heat transfer. The material's formulation yields a water vapor diffusion resistance factor (μ-value) exceeding 10,000, creating a reliable built-in vapor barrier.
For the Czech Republic and wider EU markets, fire behavior is verified under BS 476 and EN 13501-1, ensuring compliance with local safety standards for building envelopes and mechanical systems.
| Insulation Material | Cell Structure | Vapor Resistance (μ) | Flexibility | Corrosion Risk (CUI) | Installation Speed |
|---|---|---|---|---|---|
| Kingflex Elastomeric NBR/PVC | Closed-Cell (>98%) | ≥ 10,000 | High (No crack at low temp) | Negligible (Hydrophobic) | Fast (Pre-slit, self-adhesive) |
| Traditional Rock Wool | Open-Cell Fibrous | ≤ 1.20 | Rigid / Semi-rigid | High (Retains moisture) | Moderate (Requires metal cladding) |
| Polyurethane Rigid Foam | Closed-Cell (>90%) | ≥ 60 | None (Brittle) | Moderate (At joint breaks) | Slow (Requires precise cutting) |
Industrial projects require reliable supply chains. Kingflex provides end-to-end support for Czech contractors, distributors, and engineering companies, offering direct shipping to key industrial hubs like Prague, Ostrava, Brno, and Plzeň.

Technical DataTo achieve target thermal resistance (R-value) and avoid condensation, correct material sizing is essential. Kingflex supplies elastomeric sheets and pre-formed tubes in various standardized thicknesses (ranging from 6mm to 50mm) to match the outer diameter of commercial metal piping systems (ranging from 6mm to 114mm ID).
When insulating cold systems in central air-conditioning networks or process piping, structural engineers must calculate the minimum thickness needed using local weather data (relative humidity and dry bulb temperature). Our R&D team can provide these calculations to verify the design against condensation risks.
