Scudoflex NBR
Flexible elastomeric foamFlexible, closed-cell elastomeric insulation with high moisture-vapour resistance and low thermal conductivity.
Built for reliable thermal and moisture control.
Scudoflex NBR is engineered for duct and pipe insulation across HVAC, chilled-water, cold-water, heating and cooling systems. Its refined closed-cell structure helps limit heat transfer and control condensation across demanding temperature gradients.
Available as tubes, rolls and sheets, with unfaced, aluminium-foil and glass-cloth finishes. External installations require suitable protection from weather and ultraviolet exposure.
