Kingflex
Highly adaptable closed-cell insulation designed to prevent corrosion under insulation (CUI) and limit smoke toxicity in public and industrial structures across Germany.
Germany has established some of the world's most rigorous regulatory frameworks regarding energy conservation, fire prevention, and indoor environmental health. The Building Energy Act (Gebäudeenergiegesetz - GEG) mandates highly efficient thermal containment on all hot water pipes, heating systems, and cooling infrastructure. Traditionally, standard elastomeric rubber foam insulation products containing halogens (chlorine and bromine) have been widely deployed due to their flexibility and flame-retardant properties. However, under high-temperature exposure during a fire, halogenated substances undergo pyrolysis, releasing toxic acid gases like hydrogen chloride (HCl). When these gases contact water, they form highly corrosive hydrochloric acid, threatening human life in escape pathways and severely damaging sensitive server equipment and electrical frameworks.
This dynamic has prompted a major pivot toward halogen-free (HF) insulation systems. Projects aligned with the German Sustainable Building Council (DGNB - Deutsche Gesellschaft für Nachhaltiges Bauen) place high priority on materials free from halogens, plasticizers, and volatile organic compounds (VOCs). Halogen-free flexible elastomeric foams (FEF) offer an exceptional solution: they ensure low smoke density and toxicity (complying with EN 13501-1 ratings like B-s1, d0 or B-s2, d0) while delivering a thermal conductivity value as low as λ10°C ≤ 0.036 W/(m·K). For German engineering consultants, plant operators, and HVAC planners, implementing certified halogen-free systems is no longer a secondary design option; it is essential for risk mitigation and compliance.
In municipal drinking systems and food-processing industrial setups across Bavaria, Baden-Württemberg, and North Rhine-Westphalia, stainless steel pipelines are standard. If moisture containing chloride ions penetrates the insulation material and reaches the hot metal surface, it can cause Stress Corrosion Cracking (SCC). Halogen-free elastomeric insulation products, which feature a closed-cell matrix, are specifically formulated with trace chloride levels below 50 ppm (complying with DIN 1988-200 and EN 13480-14 protocols). This prevents chemical attack on the pipes, safeguarding the physical infrastructure for decades.
From dense municipal networks to demanding marine engineering, our systems are optimized for specialized local applications.
Under the high-density server configurations of the Frankfurt cloud hub, our halogen-free NBR-based sheet rolls are deployed on air conditioning and chilled water pipelines. In the event of a fire, the absolute absence of acidic fumes protects servers worth millions from corrosive micro-deposition.
For vessel building and retrofitting at German northern shipyards, insulation must comply with strict marine safety directives (IMO / MED certifications). Our halogen-free tubing blocks sound propagation and resists continuous humidity and saltwater mist in tight bulkheads.
Sustainable housing developments require insulation with low outgassing properties to ensure healthy indoor air. Our closed-cell rubber sheet rolls supply high energy-conservation factors under the German GEG parameters without releasing formaldehyde or particulate matter.
Verified laboratory performance data satisfying DIN EN 14304 parameters for flexible elastomeric foams.
