View SpecificationsLondon's dense commercial infrastructure and strict building regulations place extraordinary demands on thermal engineering designs. From deep-level commercial building service basements in the City of London to District Heating Schemes in Greenwich and Battersea, modern developers are pushed to meet the Net-Zero initiatives under the London Plan 2021.
Preventing surface condensation, minimizing thermal envelope degradation, and managing noise levels in high-density multi-use spaces are critical goals. Our premium NBR/PVC closed-cell elastomeric foam and accessories directly address these requirements. They provide low thermal conductivity ($\lambda \le 0.034 \, \text{W/(m}\cdot\text{K)}$ at $0^\circ\text{C}$) and robust water vapor resistance ($\mu \ge 10,000$), ensuring compliance with the stringent requirements of BS EN 14304 and BS 476 fire rating standards.
Providing seamless material procurement, customizable technical specifications, and end-to-end logistics solutions for large-scale infrastructure projects.
Elastomeric foam insulation is no longer just a pipeline wrap; it is a foundational component of modern building envelopes. By integrating high-density NBR/PVC closed-cell structures with specialized joint accessories—such as Class 0 adhesive 520 and reinforced aluminum foil tapes—we provide continuous vapor seals. These systems are critical for prevent condensation on chilled water pipes and HVAC ducts, eliminating the risk of structural mold development and indoor air quality degradation in institutional buildings, hospitals, and high-rise apartments.
Furthermore, for ultra-low temperature networks, such as cryogenic processes and liquefied gas transport pipelines, our flexible cryogenic elastomeric systems offer micro-cellular structures that remain stable down to $-200^\circ\text{C}$, preventing thermal shock and mechanical failure.
Our manufacturing processes rely on advanced vulcanization and foaming technology, creating an even, dense cell distribution (closed-cell rate exceeding 98%). Here are our standard dimensions and physical parameters:

Strict adherence to BS 476, CE, REACH, RoHS, UL94, and ASTM certifications. Fully traceable manufacturing batches.
Our materials undergo regular testing by third-party laboratories to ensure consistent quality and safety compliance across international regions.
Proven protection in extreme environments, from commercial HVAC system designs in Greater London to low-temperature cryogenic systems.
District energy systems require long-lasting performance. In London's underground service tunnels, standard insulation can suffer from moisture ingress, leading to corrosion under insulation (CUI) and energy loss. By specifying Kingflex Closed-Cell NBR/PVC Rubber Foam rolls paired with high-performance Class 0 vapor sealing accessories, engineering firms have created robust barrier systems. These setups prevent thermal bridging, isolate sound in structural risers, and keep heat gain to a minimum.
Managing acoustic reverberation and thermal transfer within ventilation ductwork is crucial for maintaining indoor air quality and workspace comfort. Our elastomeric open-cell acoustic insulation systems absorb sound while maintaining a closed-cell moisture barrier layer externally. This design protects the ductwork from condensation issues, even during peak summer temperatures.
