Resistant to water vapour diffusion (μ factor)

Our materials are resistant to water vapour diffusion. The higher the resistance to the penetration of water vapour, (denoted by Mu (μ)), the greater the consistency of performance over a period of time. This benefit is significant when insulating cold items, where insulation thicknesses are chosen so as to achieve a surface temperature above the ambient dewpoint. Ambient humidity will try to breach the insulation in order to achieve equilibrium conditions. Because the thermal conductivity of water is 0,58 W / (mK), and therefore about 16 times higher than our insulation, any absorption of water vapour could reduce the insulation efficiency. The formation of condensation on the surface of tubing and ducting is the main cause of corrosion beneath insulation which quickly leads to damage of pipes and ducts.
