Chilled Water Pipe Insulation
Specialist pipe insulation for chilled water systems, fan coil units, and cooling pipework. Chilled water pipework operates at low temperatures — typically 6–12°C — making condensation control the primary challenge. Our chilled water pipe insulation products are engineered to prevent surface condensation, protect against moisture ingress, and maintain system efficiency across commercial HVAC and cooling installations.
Closed-cell elastomeric foam insulation is the industry-standard choice for chilled water pipework, providing an integral vapour barrier that resists moisture diffusion and prevents the condensation that leads to corrosion, mould, and energy loss. Products such as Armaflex EVO and K-Flex ST are widely specified for chilled water applications in commercial buildings, data centres, hospitals, and industrial cooling systems.
