Economy Pipe Insulation 22 x 13mm x 1m 45 Pack (57077)

Hello ClareRussell, The 22mm measurement refers to the pipe size that this will fit onto. The 13mm refers to the thickness of the insulation itself. Thank you for using Q&A

Hello DDavidD, The manufacturer has advised that the Class P fire rating refers to an older fire rating standard, which has been updated to the newer euro E fire rating. We are working to update the website to reflect the newer rating. Thanks for using Q&A.

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

Hello Stuhulk, Every installation/usage is different due to the varying circumstances of the site and environment. Therefore we advise that you contact a local tradesperson who will be able to view and assess your particular requirements. They will be able to provide further advice for the installation/usage of the insulation. Thank you for using Q&A.

Hello Daniel2599, This is not suitable for being put outside. It isn't waterproof nor UV-Protected so may rapidly degrade in external conditions. Thank you for using Q and A, EC.
