View Technical Specifications →The Barcelona metropolitan area is undergoing a profound industrial and structural change, driven by Spain's National Integrated Energy and Climate Plan (PNIEC) and EU decarbonization directives. As Catalonia transitions toward carbon neutrality, thermal efficiency in commercial building HVAC designs, industrial district cooling networks (such as Districlima), and marine engineering systems has become critical.
In Mediterranean climates like Barcelona, the main challenge is managing hot, humid summers combined with coastal atmospheric conditions. This environment demands insulation with high water vapor transmission resistance (expressed as μ-value ≥ 10,000) and exceptionally low thermal conductivity (λ ≤ 0.034 W/m·K at 0°C). Without these specifications, condensation immediately compromises structural integrity, creates biological hazards (mold growth), and reduces mechanical efficiency.
Our elastomeric rubber foam sheets strictly align with Spain's Technical Building Code (Código Técnico de la Edificación - CTE), particularly the DB-HE section focusing on energy saving, ensuring that thermal installations minimize energy losses.
Built-in water vapor barrier eliminates the need for separate external wraps. This reduces labor costs by up to 40% during complex retrofits in historic municipal quarters like Eixample and Ciutat Vella.
Targeted solutions developed for specific commercial, marine, and high-tech sectors in the region.
With major cooling grids expanding in 22@ Barcelona (Poblenou innovation district), our closed-cell rubber sheet rolls act as the primary defense against pipe condensation and thermal gain in high-flow cold water pipelines.
Serving boatbuilders and refit shipyards at the Port of Barcelona. Our marine-grade elastomeric sheets offer superb acoustic damping and resistance to salt spray, oil degradation, and structural vibration.
As Barcelona becomes the main digital gateway for Southern Europe, hyper-scale data centers use our cryogenic and standard elastomeric sheets to insulate refrigerant coolant networks, preventing expensive micro-dripping.

Kingflex Insulation Co., Ltd. operates in Dacheng, China—the global capital of energy-saving green building materials. Backed by the Jinwei Group (established in 1979, with over 40 years of pioneering research), we run 5 state-of-the-art fully automated continuous extrusion assembly lines.
This automated capacity yields over 600,000 cubic meters annually, insulating project sites across 66 countries. For Barcelona importers, developers, and distributors, our supply chain advantages include:
Developing the next generation of eco-friendly, halogen-free, and high-performance elastomeric compounds.
Engineering NH/NBR elastomeric foams that eliminate chlorine and bromine. This ensures zero acid-gas emissions during fire exposure, a critical safety requirement for Barcelona metro tunnels and shopping centers.
Replacing petroleum-derived plasticizers with vegetable-based alternatives. This lowers the embodied carbon footprint, helping architects earn LEED and BREEAM certifications for sustainable construction.
Developing ultra-thin hybrid aerogel-rubber sheets for space-constrained piping where traditional thicknesses are not viable, achieving class-leading thermal protection.
A global leader in research, development, and high-volume manufacture of elastomeric materials.
