Phenolic Pipe Insulation
Phenolic Pipe Insulation — UK Specialist Supplier
Shop our range of phenolic pipe insulation including Supaphen and Kingspan Kooltherm. Phenolic foam offers the lowest thermal conductivity of any rigid pipe insulation, making it the preferred choice for chilled water, district heating, domestic hot and cold water and refrigeration pipework where space is limited and maximum thermal performance is required.
Product Ranges
- Supaphen Phenolic Pipe Sections — Foil-faced rigid phenolic foam pipe insulation sections for domestic and commercial pipework. Available in a wide range of bore sizes and wall thicknesses to suit 15mm to 219mm pipe. Lightweight, easy to cut and install, with a bright foil facing that provides an integrated vapour barrier.
- Kingspan Kooltherm Pipe Insulation — Premium phenolic pipe insulation with a thermal conductivity as low as 0.021 W/mK — the best available for any pipe insulation product. Ideal for applications where insulation thickness must be minimised, such as service voids, plant rooms and district heating networks.
Why Choose Phenolic Pipe Insulation?
- Lowest thermal conductivity — phenolic foam achieves λ values of 0.021–0.025 W/mK, significantly better than mineral wool (0.034–0.040 W/mK) or elastomeric foam (0.033–0.040 W/mK)
- Thinner insulation for the same U-value — saves space in congested service voids and plant rooms
- Foil-faced — integrated vapour barrier suitable for chilled water and cold pipework
- Compliant with Part L and CIBSE Guide C — suitable for use in new build and retrofit commercial and domestic projects
- Lightweight and easy to install — can be cut with a standard knife and secured with foil tape
Common Applications
- Chilled water flow and return pipework in commercial HVAC systems
- District heating and communal heating network pipework
- Domestic hot and cold water pipework in new build and retrofit
- Refrigeration and cold store pipework
- Pipework in service voids where insulation thickness is restricted
