Kingflex
Ireland's construction and industrial sectors are undergoing a monumental transition driven by the Climate Action Plan and the Near Zero Energy Building (NZEB) mandates. Technical Guidance Document L (Part L) outlines strict conservation of fuel and energy parameters, making high-efficiency thermal insulation a priority. Kingflex NBR/PVC elastomeric rubber foam insulation is engineered to address these strict parameters by preventing heat loss, eliminating condensation risk, and offering sound dampening in commercial, residential, and industrial environments.
Whether you are engineering a multi-megawatt hyperscale data center in Dublin, setting up a pharmaceutical cleanroom in Cork, or retrofitting public commercial buildings, selecting the correct insulation density, closed-cell ratio, and thermal conductivity rating is essential for achieving compliance and long-term operating efficiency.

| Density | 40 - 55 kg/m³ | Ensures mechanical structure integrity | Optimizes flexibility during installation around complex valve manifolds and elbows. |
Our completely closed-cell configuration prevents condensation on chilled water pipes, which otherwise leads to damp insulation, reduced performance, and ceiling damage in commercial complexes.
Kingflex insulation utilizes specialized halogen-free and fire-retardant chemistry to maintain BS 476 and Euroclass compliance, prioritizing structural safety and public protection.
With an elastic recovery rating above 80%, our rubber foam handles complex physical strain, movements, and vibrations without developing cracks or microscopic air pockets.
Finding the right combination of cost and quality is a primary challenge for Irish MEP contractors. Buying insulation through standard distribution channels in the EU often comes with high markups. Kingflex acts as a factory-direct manufacturer and trading combo, bypassing middle layers to lower total project costs.
From our manufacturing hub, we orchestrate full container shipments directly to the Port of Dublin, Port of Cork, or Shannon Foynes. With specialized export packaging and container load optimization, we ensure bulk shipments of sheet rolls and pipe sections arrive in perfect physical condition, protected from oceanic humidity.
We work with international logistics providers to coordinate containerized shipments with customs clearance documentation (C88 and import duty declarations), ensuring deliveries align with your site schedules.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our research, development, and production facility is located in Dacheng, China—a hub for green building materials. As an energy-saving, environmentally friendly enterprise, we concentrate on the research, development, production, and sales of high-performance insulation systems.
Established by the Jinwei Group, which carries more than 40 years of manufacturing history since its founding in 1979, we operate with energy conservation and consumption reduction as our core concepts. Our team of eight professional R&D engineers, six international sales advisors, and 230 production staff work together to provide first-class service to clients globally.
At present, Kingflex operates five large automatic assembly lines. Our production processes are certified under the ISO 9001 Quality Management System, ensuring every cubic meter of rubber foam matches global standards before dispatch.
Our dedicated R&D lab continuously tests raw materials for thermal retention, moisture resistance, and fire behavior. We monitor parameters such as thermal degradation, cell wall consistency, and tensile recovery to ensure optimal insulation performance in harsh damp environments.
Providing high-efficiency thermal insulation, cold conservation, and sound reduction systems for Ireland's leading building and HVAC sectors.

View SpecificationsOur elastomeric insulation relies on a specialized blend of Nitrile Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC). This synthetic polymer blend combines NBR's low thermal conductivity and flexibility with PVC's resistance to ozone, flame spread, and mechanical wear.
During extrusion and vulcanization, we inject environmental expansion agents to create a uniform, closed-cell matrix. Over 98% of the cells are closed, trapping dry air. This structure keeps thermal conductivity low even when exposed to high environmental humidity, preventing moisture from compromising the insulation performance over time.
Additionally, the smooth skin finish of NBR/PVC helps prevent dust and dirt accumulation. This simplifies cleanroom sanitization procedures in pharmaceutical and microelectronic manufacturing facilities.
Unlike mineral wool or fiberglass materials, NBR/PVC does not settle, pack down, or lose density over years of operation. The built-in vapor barrier stays intact across the entire material thickness, meaning performance remains stable without requiring additional foil wraps.
"Choosing high-density closed-cell insulation prevents moisture infiltration and cold-bridge failures, helping to keep heating and cooling costs down over the operational lifetime of the building."
