Hello PeterMc,
The ‘Improvement’ was actually a reduction in the THERMAL CONDUCTIVITY of the material a few years ago.
-The THERMAL CONDUCTIVITY was ‘improved’ from 0.04W/mK @ Zero Degrees Centigrade down to 0.035W/mK @ Zero. This means that the material now transmits 0.035 Watts of Energy/Heat, through a metre of the material, when the ambient temperature is Zero. This was previously the higher figure of 0.04W/mK energy/heat that was lost.
-By virtue of the lower thermal conductivity loss then the insulation value of the pipe insulation has increased/improved.
-I also agree that we should probably change this on the portal and that we should change the terminology to the following :-
-‘Improved, Lower Thermal Conductivity’ instead of ‘Improved Thermal Conductivity’
I hope this is useful.
Thank you for using Q and A.JB
