Isopartner Supaphen Phenolic Foil Covered Pipe Insulation 1m Long
How to measure?
Pipe insulation sizes refer to the outside diameter of the pipe — not the bore (internal diameter).
|←— OD —→|Wrap a tape measure around the pipe, divide by π (3.14) to get the OD. Or use calipers across the outside of the pipe directly.
Isopartner Supaphen Phenolic Foil-Faced Pipe Insulation – 1m
Supaphen is a high-performance rigid phenolic foam pipe insulation with a factory-applied Class 0 aluminium foil vapour barrier facing. With an independently tested thermal conductivity of λ = 0.025 W/(m·K) at 10°C mean temperature, it achieves required insulation values at thinner wall thicknesses than mineral wool or elastomeric foam alternatives — making it an excellent choice for space-critical commercial HVAC, chilled water, and heating installations. Supplied in pre-slit 1m sections for pipe outside diameters from 15mm to 76mm, with 15mm, 20mm, and 25mm wall thicknesses.
Supaphen is a strong alternative to Kingspan Kooltherm for projects requiring ultra-low λ phenolic foam insulation at competitive pricing.
Key Features & Benefits
- Ultra-Low Thermal Conductivity: λ = 0.025 W/(m·K) at 10°C — independently tested at Exova Warrington Fire. Achieves Part L and CIBSE Guide C compliance at reduced wall thicknesses.
- Outstanding Fire Performance: BL-s1,d0 (EN 13501-1) — very limited smoke production, no burning droplets. Independently tested to EN 13501-1 as a pipe section.
- Closed-Cell Structure: Resists moisture ingress and maintains long-term thermal performance in humid plant room environments.
- Silicate Bore Coating: Unique factory-applied silicate solution throughout the product — not just at the surface. Remains effective after cutting for elbows, fittings, and welded joints. Compliant with NES Y50 specification.
- Class 0 Foil Facing: Factory-applied plain aluminium foil vapour barrier. Seal joints with self-adhesive aluminium foil tape for a continuous vapour barrier.
- Zero ODP: CFC/HCFC-free with zero ozone depletion potential.
- Load-Bearing Option: Available in higher densities for thermally insulating pipe supports (contact us for details).
