Kingflex
High-performance elastomeric sheets designed specifically for temperature ranges, condensation prevention, and fire safety regulations standard in Irish commercial projects.
The industrial and commercial building sectors in Ireland are experiencing an unprecedented transition. Driven by the Irish Government's Climate Action Plan and stringent updates to Part L of the Building Regulations (Conservation of Fuel and Power), engineering consultancies and HVAC system planners are demanding more robust insulation metrics. Closed-cell elastomeric rubber foam sheets are at the forefront of this revolution, providing the essential thermal resistance needed to eliminate energy leakage across cold water systems, chilled water loops, and air distribution ductwork.
"To meet Ireland's Net-Zero targets by 2050, commercial facilities must reduce operational HVAC energy consumption by up to 35%. Modern closed-cell elastomeric rubber foam sheets provide the thermal barrier required to meet these ambitious sustainability objectives."
Given Ireland's maritime climate characterized by persistent high relative humidity levels, mechanical systems running below ambient temperatures are highly susceptible to surface condensation. Uncontrolled condensation leads to moisture accumulation, compromising the surrounding structure, degrading indoor air quality via mold growth, and inducing pipe corrosion under insulation (CUI). Kingflex's NBR/PVC closed-cell matrix offers a high moisture vapor diffusion resistance factor (μ ≥ 10,000), ensuring long-term thermal integrity without the need for additional external vapor jackets.
Our materials undergo strict testing to ensure they comply with local BS 476, European EN 13501-1 fire ratings, and global CE frameworks.

How our elastomeric foam sheet rolls solve design challenges across diverse local industrial sub-sectors.
Dublin is one of Europe's premier data center hubs. Cooling infrastructure must run non-stop. Our closed-cell rubber sheet rolls prevent condensation on chilled water pipes and air handling systems, safeguarding electronic systems from potential drip hazards.
Irish biopharma facilities require precise temperature controls. Our dust-free and fiber-free NBR/PVC matrix prevents particulate contamination in cleanroom environments, ensuring full compliance with ISO cleanroom design standards.
From Dublin offices to Limerick commercial retail spaces, HVAC ductwork insulated with Kingflex sheets prevents energy losses, optimizing thermal efficiency and ensuring compliance with national energy efficiency regulations.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Kingflex research development and production department is located in the well-known capital of green-building materials in Dacheng, China. It is an energy-saving, environmentally friendly enterprise concentrating on research, development, production, and sales.
In operation, Kingflex takes energy saving and consumption reduction as its core concept. We provide insulation solutions via consulting, R&D production, installation guidance, and post-sale service to lead the development of the global building materials industry.
Established by the Jinwei Group, which possesses more than 40 years of history, Kingflex has deep roots in industrial engineering. Kingway Group was established in 1979 and was the first manufacturer of thermal insulation materials north of the Yangtze River.

High-performance elastomeric tubular systems and high-density industrial rock wool solutions.
Traditional mineral wool systems have long been used in industrial applications across Ireland. However, their open-fibrous structure makes them susceptible to moisture absorption. When water penetrates open insulation, the overall thermal conductivity increases significantly, leading to energy losses and potential corrosion of underlying pipelines.
By contrast, Kingflex closed-cell rubber foam features millions of microscopic air pockets. This design provides built-in water vapor resistance, preventing moisture ingress and eliminating the need for external vapor barrier coatings.
Part L Section 2 Compliance: Under Irish regulations, any insulation material used in mechanical plumbing installations must prove long-term performance stability without decay from humidity. Kingflex elastomeric insulation achieves this requirement naturally, ensuring stable thermal performance over decades.
Leveraging our 600,000 m³ annual production capacity, we provide optimized shipping logistics to all Irish destinations. Kingflex products are compressed using vacuum packaging techniques, minimizing freight volume and shipping costs to Dublin Port, Cork Port, and Belfast Port. All shipments are fully traceable and include complete quality certification documentation.
